<p>For many IT Managers, there is no moment more gut-wrenching than running an automated vulnerability scan, receiving a "clean" green report, and then having a manual Penetration Test uncover 10 critical vulnerabilities within hours.</p><p>This gap often leads management to ask: "If the automated tools said we were safe, why are we paying experts for manual testing? Is the scanner just a psychological comfort?" In reality, the failure of a scanner to find these holes isn't about software quality—it's about the fundamental difference between "tools" and "human logic." This article reveals why automated scanning can never fully replace manual human testing.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Smoke Detectors vs. Master Thieves: A Difference in Strategy</h2><p>To understand the difference, the best analogy is a "Smoke Detector" versus a "Master Thief."</p><p>An automated scanner is like a smoke detector on the wall. It runs 24/7 and is excellent at identifying the known signatures of a fire. It is cost-effective and efficient for broad, daily checks. However, a detector is static; it doesn't think about how to bypass the sensors. It can tell you if there is smoke now, but it cannot tell you if a hacker has already picked the lock on the back door.</p><p>A manual Penetration Test is like hiring a professional master thief. He doesn't just look at the detector; he looks for gaps in security shifts, tries to crawl through vents, or looks for the spare key you left in a drawer. A manual tester (Pentester) possesses logical reasoning and "hacker's intuition"—technologies that no automated code can currently replicate.</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">The Blind Spot of Scanners: Business Logic Flaws</h2><p>Why do automated tools miss the most critical vulnerabilities? The primary reason is that scanners do not understand your "Business Logic."</p><p>Scanners are great at finding technical flaws, such as an outdated server version. However, they cannot judge if a valid request leads to an invalid result. For example, in a transfer system, a hacker might change a transfer amount from a positive number to a negative one to increase their own balance. To a scanner, this is a perfectly formatted data request, so it reports it as "Safe."</p><p>A human pentester, however, will proactively challenge these workflows. They will attempt to manipulate order amounts, gain unauthorized access to other customers' data, or test for flaws in the business logic itself. These logic-based attacks are the primary battlefield for modern financial fraud and data breaches, and they remain a permanent blind spot for automated scanners.</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">The Power of Chaining: Combining Minor Flaws for Major Hacks</h2><p>Another reason scanners fail is their lack of "Vulnerability Chaining" capability.</p><p>In a scan report, you might see three "Low" risk findings. Individually, these may seem harmless to an IT department. However, an experienced pentester sees them as puzzle pieces. They might use a low-risk information leak to find a username and then leverage a minor misconfiguration to enter the internal network.</p><p>Scanners view vulnerabilities in isolation. They cannot evaluate the explosive threat created when multiple minor flaws are combined. This is why a scanner says you are safe, but a pentester ends up with full control of your database. This ability to "chain" attacks is something only a human hacker with real-world experience can achieve.</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Configuration Errors and Hidden Side Doors</h2><p>Modern enterprise IT environments are incredibly complex. Automated tools often "skip" testing when faced with non-standard configurations or complex authentication flows because they cannot log in automatically.</p><p>Pentesters dive deep into these complexities. They look for API keys left in frontend code or test for "Broken Function Level Authorization." These hidden "side doors," buried deep within the system and requiring multi-step interactions to trigger, are areas that automated scanners simply cannot reach.</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Building a Resilience Loop: How Scanners and Pentesters Work Together</h2><p>This doesn't mean automated scanning is worthless. On the contrary, scanners and penetration testing should be complementary.</p><p>We recommend that businesses include automated scanning in their "Daily Maintenance" to catch obvious system updates and configuration issues. Manual Penetration Testing should be reserved as a "Deep Check-up" to simulate complex, objective-driven attacks.</p><p>When you realize that a scanner is only "the first door of defense" rather than the whole solution, you begin to build genuine cyber resilience. Security shouldn't be about a perfectly green report; it should be a dynamic process of continuous testing and strengthening alongside real-world experts.</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">🛡️ Ready to Strengthen Your Security?</h2><p style="text-align:center;">UD is a trusted <strong>Managed Security Service Provider (MSSP)</strong><br>With 20+ years of experience, delivering solutions to 50,000+ enterprises<br>Offering Pentest, Vulnerability Scan, SRAA, and a full suite of cybersecurity services to protect modern businesses</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/en/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">Consult Security Experts Now</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/en/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">Conduct a PenTest for Your Enterprise</a></div><p>&nbsp;</p><p>&nbsp;</p>

<p>许多 IT 经理都经历过这种令人心跳加速的时刻：公司刚刚花钱跑完自动化漏洞扫描，拿到一份显示“安全无虞”的绿色报告。然而，随后进行的人工渗透测试（Penetration Test），却在短短几小时内被专家挖出 10 个足以让系统瘫痪的致命漏洞。</p><p>这种巨大的落差常让管理层产生怀疑：既然自动化工具已经显示安全，为什么还要花钱请专家做人工测试？难道扫描器只是心理安慰吗？事实上，扫描器漏掉漏洞并非软件质量问题，而是“工具”与“人类思维”之间的本质差异。本文将揭开为什么自动化扫描无法完全取代人工测试的真实原因。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">烟雾侦测器与专业神偷的定位差异</h2><p>要理解这两者的区别，最贴切的比喻就是“烟雾侦测器”与“受雇神偷”。</p><p>自动化扫描器就像是安装在墙上的烟雾侦测器。它二十四小时运行，能快速识别已知的火灾特征，对于大范围的日常巡检非常有效且成本低廉。然而，侦测器是静态的，它不会主动思考如何绕过监控。它只能告诉你“现在有没有烟”，却无法告诉你黑客是否已经撬开了后门的锁。</p><p>人工渗透测试则像是一位受雇的“专业神偷”。他不会只看你有没有装侦测器，他会寻找保安交班的空档，尝试通过冷气通风管爬入金库，或者利用你留在桌上的备用钥匙进入系统。测试员具备的是逻辑推理能力与黑客的直觉，这正是目前任何自动化代码都无法完全取代的技术。</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">扫描器看不见的致命伤：业务逻辑漏洞</h2><p>为什么自动化工具会漏掉最关键的漏洞？最核心的原因在于扫描器看不懂你的“业务流程（Business Logic）”。</p><p>扫描器擅长发现的是技术性缺陷，例如你的服务器版本是否过期。但它无法判断一个正确的请求是否会导致错误的结果。例如，在一个转账系统中，如果黑客将转账金额从正数改为负数，从而让自己的账户金额不减反增。对于扫描器来说，这是一个格式完全正确的数据传输，它会毫无警觉地报平安。</p><p>然而，人工渗透测试员会主动挑战这些流程。他们会尝试篡改订单金额、越权查看其他客户的资料、或者测试流程中的漏洞。这种针对业务逻辑的攻击，是目前金融诈骗与数据外泄的主战场，也是自动化扫描器永远的盲点。</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">漏洞连连看的威力：攻击链的串联与突破</h2><p>另一个让扫描器失效的原因，是它缺乏“漏洞串联（Vulnerability Chaining）”的能力。</p><p>在扫描报告中，你可能会看到三个“低风险”的微小缺陷。单独看这些问题， IT 部门可能觉得不需要优先处理。但经验丰富的渗透测试员会像拼图一样将它们串起来：他可能先通过一个低风险的信息泄露获取员工账号，再利用另一个配置错误进入内网。</p><p>扫描器只会孤立地看待每一个漏洞，无法评估多个细微弱点叠加后产生的爆炸性威胁。这就是为什么扫描报告说你很安全，但渗透测试员却能直接拿走你数据库控制权的原因。这种串联攻击的能力，只有具备实战经验的人类黑客才能达成。</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">配置错误与隐藏的侧门：发现被忽略的安全死角</h2><p>现代企业的 IT 环境极其复杂。自动化工具在面对非标准配置或复杂的身份验证流程时，往往会因为无法自动登录而选择“跳过”。</p><p>渗透测试员则会针对这些复杂环节进行深度挖掘。他们会观察开发人员是否在前端代码中遗留了密钥，或者测试是否存在“失效的功能级授权”。这些隐藏在系统深处、需要多步骤交互才能触发的安全死角，是自动化扫描器难以触及的领域。</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">构建防御闭环：扫描与测试的协作策略</h2><p>这并不代表自动化扫描没有价值。相反，扫描器与渗透测试应该是互补的关系，而非替代关系。</p><p>我们建议企业将自动化扫描纳入“日常巡检”，用于发现那些显而易见的系统更新问题。而人工渗透测试则应作为“深度体检”，用于应对更复杂的攻击模拟。</p><p>当你意识到扫描器只是“防御的第一道门”而非全部时，你才能建立起真正的资安韧性。网络安全不应是一张全绿的报告，而应是一次次与真实专家交手后，不断强化与修補的动态过程。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">强化企业安全 🛡️ 立即行动</h2><p style="text-align:center;">UD 是值得信赖的託管安全服务供应商（MSSP）<br>拥有 20+ 年经验，已为超过 50,000 家企业提供解决方案<br>涵盖渗透测试、漏洞扫描、SRAA 等全方位网络安全服务，全面保护现代企业。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">马上谘询资安专家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">为企业进行渗透测试</a></div><p>&nbsp;</p><p>&nbsp;</p>

Why a "Clean" Security Scan Isn't Enough: 3 Reasons Automation Misses Critical Hacks

弱点扫描「全绿」仍有危险？揭开自动化工具漏掉致命漏洞的 3 大真相

弱點掃描「全綠」仍有危險？揭開自動化工具漏掉致命漏洞的 3 大真相

<p>As ransomware attacks become more frequent, insurance companies have become extremely stringent when reviewing Cyber Insurance renewals. Today, "MFA on Everything" is almost a non-negotiable baseline for receiving a premium quote. However, for many IT Managers, the reality includes one or two "Legacy Servers" running mission-critical applications on operating systems or software architectures that simply do not support native MFA.</p><p>When faced with the mandatory renewal questionnaire asking, "Is MFA implemented for all access?" IT Managers find themselves in a dilemma. Checking "No" could lead to sky-high premiums or an outright denial of coverage, but checking "Yes" could lead to a claim denial later if an incident occurs. This article provides a survival guide on using "Compensating Controls" to satisfy insurers without replacing your legacy systems.</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">The Insurer’s Bottom Line: Why the Obsession with MFA?</h2><p>From an insurer's perspective, over 80% of data breaches involve compromised credentials. If a single entry point in your environment exists without MFA protection, hackers can use it as a foothold to move laterally through your network and launch a massive attack.</p><p>Consequently, insurers care about more than just your cloud email or VPN; they are deeply concerned about privileged access to servers. Even if it's an unpatchable Windows Server 2008 that has been running for a decade, its connection to the network makes it a fatal gap in your enterprise defense. This is why "MFA on Everything" has become a critical metric for renewal.</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Never Lie on the Questionnaire: The Importance of Honest Disclosure</h2><p>Under pressure, some businesses might choose to be vague on their questionnaire or hide legacy servers that lack MFA. This is an extremely dangerous decision. Cyber insurance is built on the principle of "Utmost Good Faith."</p><p>If, during a claim investigation, forensic experts discover that a breach occurred via a legacy system you claimed was "MFA-protected" when it wasn't, the insurer has every right to void the policy and deny all payouts. For IT Managers, the most professional and secure approach is to be honest while providing a detailed explanation of your "Compensating Controls."</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Compensating Controls: Technical Alternatives to Native MFA</h2><p>When a legacy server cannot support MFA software directly, insurers often accept "Compensating Controls." This means that while you haven't installed MFA on the server itself, you have built an equivalent layer of protection around it.</p><p>One common solution is using a "Bastion Host" or "Jump Server." You can move the legacy server into a completely isolated network segment (VLAN) and prohibit all direct logins. All administrators must first log into a Jump Server secured with strong MFA. Only after successful authentication can they remotely access the legacy system. Logically, this ensures that the "access behavior" is fully protected by MFA.</p><p>A second solution involves "Micro-segmentation and Network Access Control (NAC)." By using strict firewall rules, access to the legacy server is restricted to a few specific IP addresses, and these source devices must themselves be subject to rigorous authentication. When combined with "Virtual Patching" to protect against known vulnerabilities of the old system, insurers typically recognize the effectiveness of this composite approach.</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Implementing Third-Party MFA Proxy Solutions</h2><p>If an insurer insists on seeing protection at the server level, IT teams can consider third-party MFA proxy solutions (such as Silverfort or specific Duo components) designed for legacy environments.</p><p>The advantage of these solutions is that they do not require heavy software installations on every legacy server. Instead, they intercept underlying authentication protocols (like NTLM or Kerberos) and inject an MFA confirmation step into the validation process. This allows older versions of Windows or specialized industrial control systems to gain MFA capabilities instantly without changing a single line of code or system architecture.</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Establish a Clear Decommissioning or Upgrade Plan</h2><p>Beyond technical remediations, insurers highly value a company's "Commitment to Improvement." Including a clear "Decommissioning Plan" with your renewal—stating how the company plans to phase out non-compliant legacy equipment over the next 12 to 18 months—will significantly strengthen your case.</p><p>Cybersecurity is a journey of continuous improvement. Insurers are far more willing to cover companies that understand their weaknesses and have an active plan to address them.

<p>随着勒索软件攻击日益频繁，保险公司在处理网络保险（Cyber Insurance）续保时，审核条件变得极其严苛。现在，“全面实施多因素认证（MFA on Everything）”几乎已成为保费报价的底线要求。然而，对于许多 IT 管理者来说，现实环境中总有一两台运行关键业务的“旧服务器（Legacy Server）”，其操作系统或软件架构根本无法原生支持 MFA。</p><p>面对续保问卷上那题必答的“是否所有访问都已实施 MFA？”，IT 经理往往陷入两难：勾选“否”可能导致保费飙升甚至被拒保，但勾选“是”若日后发生事故，保险公司可能以欺诈为由拒绝赔偿。本文将解析如何通过“补偿性控制措施”，在不更换旧系统的情况下满足保险公司的安全要求。</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">保险公司的底线：为什么他们对 MFA 如此执着</h2><p>从保险公司的角度来看，超过 80% 的网络入侵都与身份凭证被盗有关。如果你的环境中存在任何一个不需要 MFA 就能登录的入口，黑客就能以此为跳板，在你的内网中横向移动并发动大规模攻击。</p><p>因此，保险公司关心的不仅仅是你的云端邮件或 VPN，他们更在意那些拥有高权限的服务器访问。即便那只是一台运行了十几年、无法更新的 Windows Server 2008，只要它连接着网络，它就是整个企业防线中的一个致命破口。这就是为什么续保问卷会将“全面 MFA”列为关键指标的原因。</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">千万不要在问卷上撒谎：诚实申报的重要性</h2><p>在压力之下，有些企业可能会选择在问卷上含糊其辞，或者将未实施 MFA 的旧服务器隐藏不报。这是一个极其危险的决定。网络保险的本质是建立在“最大诚信原则”之上。</p><p>如果在理赔调查过程中，保险公司的资安专家发现黑客是通过一个你声称“已受 MFA 保护”但实际上却没有的旧系统入侵的，保险公司完全有权宣布保单无效，并拒绝支付任何赔偿金。对于 IT 管理者而言，诚实填写并提供“补偿性方案”说明，才是最专业且最安全的做法。</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">补偿性控制：无法直接实施 MFA 时的技术替代方案</h2><p>当旧服务器无法直接安装 MFA 软件时，保险公司通常接受“补偿性控制（Compensating Controls）”。这意味着你虽然没有在该服务器上安装 MFA，但你在其前端或周边建立了一层同等强度的保护。</p><p>第一个常用的方案是“堡垒机或跳板机（Jump Server）”。你可以将旧服务器移入一个完全隔离的网络网段（VLAN），并规定任何人都不能直接登录该服务器。所有管理员必须先登录一个支持强效 MFA 的跳板机，通过验证后才能远程操作旧系统。这在逻辑上达到了“访问行为受 MFA 保护”的效果。</p><p>第二个方案是实施“微隔离与网络访问控制（NAC）”。通过严格的防火墙规则，将访问旧服务器的权限限制在极少数特定的 IP 地址上，并且要求这些来源设备本身必须经过严格的身份验证。如果能配合虚拟补丁（Virtual Patching）来防范该旧系统已知漏洞，保险公司通常会认可这种组合方案的有效性。</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">引入第三方 MFA 代理解决方案</h2><p>如果保险公司坚持要看到服务器层级的保护，IT 团队可以考虑采用一些专门为旧系统设计的第三方 MFA 代理解决方案（如 Silverfort 或 Duo 的特定组件）。</p><p>这些方案的特点在于，它们不需要在每一台旧服务器上安装沉重的软件。相反，它们拦截底层的身份认证协议（如 NTLM 或 Kerberos），在验证过程中加入一个 MFA 确认步骤。这种方式可以让原本不支持 MFA 的 Windows 旧版本或特定工业控制系统，在不改动代码或系统架构的情况下，瞬间具备多因素认证的能力。</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">制定清晰的系统退役或更新计划</h2><p>除了技术补救措施，保险公司也非常看重企业的“安全改进承诺”。在续保文件中，如果你能附上一份清晰的“旧系统退役或迁移计划（Decommissioning Plan）”，说明公司预计在未来 12 到 18 个月内如何逐步淘汰这些无法合规的设备，这将极大增加你的说服力。</p><p>网络安全是一个持续改进的过程。保险公司更愿意承保那些了解自身短板并有积极计划去改善的企业。结合补偿性控制措施与清晰的更新路线图，你不仅能顺利通过续保审核，还能将保费维持在一个合理的水平，同时真正提升企业的抗风险能力。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">强化企业安全 🛡️ 立即行动</h2><p style="text-align:center;">UD 是值得信赖的託管安全服务供应商（MSSP）<br>拥有 20+ 年经验，已为超过 50,000 家企业提供解决方案<br>涵盖渗透测试、漏洞扫描、SRAA 等全方位网络安全服务，全面保护现代企业。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">马上谘询资安专家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">为企业进行渗透测试</a></div><p>&nbsp;</p><p>&nbsp;</p>

Mandatory MFA for Cyber Insurance? How to Pass Renewal with Legacy Servers

网络保险续保要求“全面 MFA”，但旧服务器不支持怎么办？

網絡保險續保要求「全面 MFA」，但舊伺服器不支援怎麼辦？

<p>In the pursuit of corporate network security, many IT Managers often face an embarrassing situation: to prevent ransomware, the company invests in state-of-the-art Endpoint Detection and Response (EDR) or Next-Gen Antivirus (NGAV). However, within three days of installation, complaints pour in from every department. Employees report slow boot times, lagging Excel files, and system crashes during video calls.</p><p>This conflict between "Security and Performance" is not accidental. Modern security tools are fundamentally different from the traditional antivirus software of a decade ago. Understanding the operating mechanisms of these tools and identifying the root causes of performance bottlenecks is key for IT departments to strike a balance between protection and productivity. This article provides a deep dive into why computers slow down and offers practical optimization strategies.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">From Static Matching to Dynamic Monitoring: The Price of Modern Security</h2><p>Traditional antivirus software relied primarily on "Signature Matching." It functioned like a security guard holding a stack of photos of known criminals, only acting when a file matched a photo. Otherwise, it had minimal impact on the system. However, modern cyberattacks, such as fileless attacks or polymorphic viruses, can easily bypass these static checks.</p><p>Modern EDR systems utilize "Behavioral Analysis." Instead of just looking at what a file looks like, it monitors what every program is "doing." It analyzes every network connection, every line of read/write command, and every activity in the memory in real-time. This 24/7 deep monitoring inevitably consumes more CPU and RAM resources. This is the fundamental reason why employees feel their computers have become "heavier."</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Primary Cause One: Scanning Strategies and Scheduling Conflicts</h2><p>Many enterprises, in an attempt to be as secure as possible, enable "Full Disk Scans" or "Deep Scans" immediately after deploying new security software. If these scans are scheduled during peak working hours, the disk I/O efficiency is instantly maxed out.</p><p>This is especially true on older computers still using traditional Hard Disk Drives (HDDs) or weaker processors, where comprehensive read/write operations can make the system extremely sluggish. Even on modern computers with SSDs, excessively frequent background scans compete for system resources with business software like ERP or large data processing tools, resulting in micro-lags during operation.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Primary Cause Two: Compatibility Conflicts Between Multiple Security Products</h2><p>Another common performance killer is the conflict between overlapping security products. Some companies install a new EDR without thoroughly uninstalling the old antivirus software, or they inadvertently run third-party security software alongside the built-in Windows Defender.</p><p>When two security products with real-time monitoring capabilities run simultaneously, they end up monitoring each other's activities. For example, when Software A tries to scan a file, Software B detects Software A's activity and scans Software A. This creates an "infinite recursion" or severe resource contention. The most obvious symptom is CPU usage staying above 90% for long periods, with the system becoming unresponsive to clicks.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Primary Cause Three: Lack of Proper Exclusion List Settings</h2><p>Not every computer activity requires deep scanning. Many IT teams forget to set up "Exclusion Lists" during deployment.</p><p>Examples include program compilation folders used by developers, large database files (SQL/Oracle), or specific internal ERP software. These files are usually massive and subject to frequent read/write cycles. If an EDR attempts real-time interception and analysis for every database read, it causes catastrophic latency. Furthermore, if backup software is not whitelisted, the security software may try to monitor hundreds of gigabytes of data transfer, slowing down the backup and dragging down the entire server's performance.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Optimization Guide: Reclaiming Performance Without Sacrificing Security</h2><p>When faced with employee complaints, IT teams should not simply disable security features but should adopt more scientific optimization measures.</p><p>The first technical strategy is to implement Staged Scanning and Intelligent Scheduling. Full disk scans should be scheduled during lunch breaks or after work hours. Enabling "Scan Priority Control" ensures that the security software automatically reduces its resource footprint when it detects the user is performing high-load tasks.</p><p>The second technical strategy is the precise configuration of Scanning Exclusion Lists. IT departments should communicate with business units to identify trusted, high-traffic applications and folders. For instance, excluding database log files, virtual machine disk images (VMDK/VHD), and known internal office applications can significantly reduce unnecessary CPU drain.</p><p>The third technical strategy is leveraging Cloud Queries instead of Local Computation. Modern, high-quality EDRs feature cloud-based threat intelligence matching. By offloading part of the analysis work to cloud servers, the local processor burden on the staff's computer is greatly reduced.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Cybersecurity as the Art of Balance</h2><p>A computer slowing down after installing a new EDR or antivirus is a warning sign that the system configuration may not yet be optimized. Cybersecurity should not come at the expense of employee productivity. Through proper scheduling, thorough removal of legacy software, and fine-tuned exclusions, IT teams can achieve protection that is both "silent and powerful."</p><p>In a modern enterprise, security tools should be like air—essential and present, but never oppressive.

<p>在追求企业网络安全的过程中，许多信息主管（IT Manager）常遇到一个尴尬的局面：为了防范勒索软件，公司投入预算安装了最先进的端点侦测与回应系统（EDR）或新一代防毒软件（Next-Gen AV），结果安装后不到三天，各部门的投诉便接踵而至。员工纷纷抱怨电脑开机变慢、开启 Excel 文件卡顿，甚至在视频会议时系统宕机。</p><p>这种“资安与效能”的冲突并非偶然。现代资安工具与十年前的传统防毒软件有着本质上的不同。理解这些工具的运作机制，并找出导致效能瓶颈的根源，是 IT 部门在保障安全与维持生产力之间取得平衡的关键。本文将深度解析导致电脑变慢的核心原因，并提供切实可行的优化策略。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">从静态比对到动态监控：现代端点安全的运作代价</h2><p>过去的传统防毒软件主要依赖“特征码比对（Signature Matching）”。它就像一个拿着通缉犯照片的保安，只有在发现文件与照片吻合时才会动作，平时对系统的干扰极小。然而，现代的黑客攻击（如无文件攻击或变种病毒）早已能轻易规避这种静态检查。</p><p>现代的 EDR 系统采取的是“行为分析（Behavioral Analysis）”机制。它不再只是看文件长什么样子，而是监控每一个程序“正在做什么”。它会实时分析每一个网络连接、每一行读写指令以及内存中的每一项活动。这种全天候、深层次的监控必然会占用更多的 CPU 与内存资源。这就是为什么员工会感觉电脑变得比以前“沉重”的根本原因。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">导致效能大幅下降第一个主因：扫描策略与排程冲突</h2><p>许多企业在部署新的资安软件后，会为了求安全而开启“全盘扫描（Full Disk Scan）”或“深度扫描”。如果这些扫描被设定在员工上班的高峰时间执行，电脑的硬盘读写效率会被瞬间占满。</p><p>特别是在仍在使用传统硬盘（HDD）或效能较弱的处理器的旧电脑上，这种全方位的读写操作会导致系统反应极度迟缓。即便是在使用 SSD 的现代电脑中，过于频繁的后台扫描也会与商业软件（如 ERP 或大型数据处理工具）争夺系统资源，造成操作过程中的微卡顿。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">导致效能大幅下降第二个主因：多重资安产品的兼容性冲突</h2><p>另一个常见的效能杀手是“一山不能藏二虎”。有些企业在安装了新的 EDR 后，没有彻底卸载旧的防毒软件，或是 Windows 内置的 Defender 与第三方资安软件产生了冲突。</p><p>当两个具备实时监控功能的资安产品同时运作时，它们会互相监控对方的活动。例如，当 A 软件尝试检查一个文件时，B 软件会侦测到 A 的活动并进行检查，这会形成一个“无限递归”或严重的资源争夺。这种冲突最明显的征状就是电脑的 CPU 使用率长时间维持在百分之九十以上，且系统对任何点击都没有反应。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">导致效能大幅下降第三个主因：缺乏合理的排除清单设定</h2><p>并不是所有的电脑活动都需要进行深度扫描。许多 IT 团队在部署时，忘记设定“排除清单（Exclusion Lists）”。</p><p>例如，开发人员使用的程序编译文件夹、大型数据库文件（SQL/Oracle），或是企业内部的特定 ERP 软件。这些文件通常体积巨大且读写频繁。如果 EDR 尝试对每一次数据库读取进行实时拦截分析，那将造成灾难性的延迟。此外，备份软件在执行任务时，如果不被列入信任名单，资安软件会尝试监控数百 GB 的数据传输，这会让备份速度变慢，同时拖累整台服务器的表现。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">优化指南：如何在不降低安全性的前提下找回电脑效能</h2><p>面对员工的抱怨， IT 团队不应简单地关闭资安功能，而应采取更科学的优化措施。</p><p>第一个技术策略是落实分阶段扫描与智能排程。应将全盘扫描设定在午饭时间或下班后进行，并开启“扫描优先级控制”，确保资安软件在检测到使用者正在进行高负载工作时自动降低资源占用。</p><p>第二个技术策略是精确设定扫描排除清单。IT 部门应与各业务部门沟通，识别出那些信任的、大流量的应用程序与文件夹。例如，排除数据库日志文件、虚拟机磁盘镜像（VMDK/VHD），以及已知的内部办公软件。这能显著降低不必要的 CPU 损耗。</p><p>第三个技术策略是善用云端查询而非本地计算。现代优质的 EDR 具备云端威胁情报比对功能。通过将部分分析工作移交给云端服务器处理，可以大幅减轻员工电脑本地处理器的负担。</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">网络安全是一场关于平衡的艺术</h2><p>安装新的 EDR 或防毒软件后电脑变慢，这是一个警讯，提醒我们系统配置可能尚未优化。网络安全不应以牺牲员工的生产力为代价。通过合理的排程、彻底清除过期软件以及精细化的排除设定，IT 团队完全可以实现“安静而强大”的防护。</p><p>在现代企业中，资安工具应该像空气一样，虽然存在且至关重要，但却不应让人感到压迫。当你的资安系统能够在后台默默运作，既能挡住黑客，又不被员工察觉时，那才是真正成功的资安部署。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">强化企业安全 🛡️ 立即行动</h2><p style="text-align:center;">UD 是值得信赖的託管安全服务供应商（MSSP）<br>拥有 20+ 年经验，已为超过 50,000 家企业提供解决方案<br>涵盖渗透测试、漏洞扫描、SRAA 等全方位网络安全服务，全面保护现代企业。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">马上谘询资安专家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">为企业进行渗透测试</a></div><p>&nbsp;</p><p>&nbsp;</p>

The Cybersecurity Dilemma: Why is Our New EDR or Antivirus Slowing Down All Staff PCs?

企业资安的兩難：为什么新的 EDR 或防毒软件会让员工电脑变慢？

企業資安的兩難：為什麼新的 EDR 或防毒軟件會讓員工電腦變慢？

<p>In the business world, email remains the most vital tool for maintaining client relationships and closing deals. Recently, however, many Hong Kong businesses have encountered a frustrating problem: legitimate business emails are suddenly landing in the client’s "Spam" or "Junk" folder, or even being bounced entirely. This doesn't just hinder efficiency; it can lead to missed multi-million dollar contracts and cast doubt on your company's professional reputation.</p><p>The primary reason behind this shift is the implementation of stricter email sender requirements by major providers like Google (Gmail) and Yahoo starting in early 2024. If your company domain lacks properly configured security records—specifically SPF, DKIM, and DMARC—your emails are highly likely to be flagged as suspicious by international mail servers. This article deciphers these three technical indicators and provides actionable remediation steps.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">The Gatekeeper: SPF (Sender Policy Framework) Explained</h2><p>Think of SPF as your company’s "Official Guest List." When your company sends an email, the recipient’s server checks your domain’s DNS records to see if the IP address sending the email is on this authorized list.</p><p>If your company uses Microsoft 365 or Google Workspace, but your DNS record doesn't include the authorization for these providers, the recipient’s server will flag the email as a spoofing attempt. Common errors include forgetting to update SPF records after switching email providers, or having an SPF record that is too long, which triggers the "10 DNS Lookup Limit" and causes the validation to fail.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">The Digital Wax Seal: DKIM (DomainKeys Identified Mail)</h2><p>While SPF checks "who" sent the email, DKIM checks if the "content" was tampered with during transit. DKIM adds a "Cryptographic Signature" to the header of every outgoing email.</p><p>The recipient’s server uses a "Public Key" found in your domain records to decrypt this signature. If the decryption is successful, it proves that the email truly originated from your domain and that the contents were not intercepted or modified by hackers. Many businesses set up their email systems but forget to publish DKIM records in their DNS, which significantly lowers the "Sender Reputation" score and lands the email in the spam folder.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">The Instruction Manual: Implementing DMARC Policy</h2><p>DMARC is the most critical component of the email authentication ecosystem. It acts as an "Instruction Manual" you provide to the recipient’s server, telling it: "If an email claiming to be from us fails SPF or DKIM checks, what should you do with it?"</p><p>DMARC implementation typically follows three stages:<br>The Monitoring Policy (p=none): This allows you to observe unauthorized usage without blocking any emails.<br>The Quarantine Policy (p=quarantine): This sends emails that fail authentication to the recipient’s spam folder.<br>The Reject Policy (p=reject): This instructs the recipient's server to block and bounce all unauthenticated emails entirely.</p><p>If your company has no DMARC record at all, modern mail systems view your domain as unmanaged and untrustworthy—the most common reason for emails being marked as SPAM after the 2024 rule changes.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Why Fixing These Issues Is Urgent and Essential</h2><p>Cyber fraud and phishing are rampant globally, with hackers frequently spoofing legitimate sender names to deceive victims. To protect users, international email providers no longer trust "unauthenticated" emails.</p><p>For Hong Kong businesses, this is more than just a technical glitch; it’s a matter of "Brand Trust." If your sales team’s quotations constantly land in junk folders, your domain reputation is being eroded. If left unaddressed, your domain could be blacklisted globally. Rebuilding a damaged reputation can take months and cost significant resources.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Action Guide for IT Managers: How to Detect and Fix</h2><p>To ensure your emails land in the inbox, IT departments or cybersecurity partners should follow these steps:</p><p>Step One: Perform a Domain Diagnosis. Use professional online tools like MxToolbox or Dmarcian. Enter your domain to check whether SPF, DKIM, and DMARC are correctly deployed and valid.</p><p>Step Two: Clean Up Legacy Authorized Records. Remove any third-party email service providers you no longer use (e.g., old newsletter systems) to ensure your SPF record is concise and efficient.</p><p>Step Three: Gradually Implement DMARC. Start with a p=none policy to collect reports for a month or two. Ensure that all legitimate business communications—including emails from ERP or HR systems—are authenticated correctly before moving to p=quarantine or p=reject policies to fully eliminate spoofing.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Bringing Your Business Communication Back on Track</h2><p>While email authentication involves many technical details, its core goal is to build "Digital Trust." By correctly configuring SPF, DKIM, and DMARC, you are essentially placing an official "Anti-Counterfeit Label" on every email you send.</p><p>This does more than just ensure 100% delivery to your client’s inbox; it protects your clients from receiving fraudulent emails disguised as your company.

<p>在商业世界中，电子邮件是维系客户关系与达成交易最重要的工具。然而，许多香港企业最近都遇到了一个棘手的问题：原本往来正常的公务邮件，突然被客户反映掉进了“垃圾邮件箱（SPAM）”，甚至直接被退信。这不仅影响工作效率，更可能让公司错失数百万元的生意合约，甚至让客户对公司的专业形象产生怀疑。</p><p>这种现象的背后，主要是因为 Google (Gmail) 与 Yahoo 自 2024 年起实施了更严格的邮件发送者验证要求。如果你的公司域名（Domain）没有正确设定三项关键的安全记录——SPF、DKIM 与 DMARC，你的邮件极大机会被国际邮件服务商视为可疑邮件。本文将为你拆解这三大技术指标，并提供修复建议。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">邮件保安的门卫：SPF 发送者授权清单</h2><p>想象一下，SPF（Sender Policy Framework）就像是你公司的一份“官方授权访客清单”。当你的公司寄出一封邮件时，收件方的服务器会去查看你域名的 DNS 记录，确认寄出邮件的那个 IP 地址是否在这份清单上。</p><p>如果你的公司使用的是 Microsoft 365 或 Google Workspace，但你的 DNS 记录中没有包含这些服务商的授权记录，收件方就会认为这是一封冒充邮件。常见的错误还包括：公司更换了邮件服务商后忘记更新 SPF，或是 SPF 记录中包含的授权清单过长，触发了 DNS 查找次数上限（10 次限制），导致验证失效。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">邮件的防伪封条：DKIM 数字签名技术</h2><p>如果说 SPF 是检查“谁寄的”，那么 DKIM（DomainKeys Identified Mail）就是检查“内容有没有被篡改”。DKIM 会在每一封寄出的邮件标签中加入一段“加密签名”。</p><p>收件方的服务器会利用你域名记录中的“公开金钥（Public Key）”来解密这个签名。如果解密成功，则证明这封邮件确实是从你的域名发出，且邮件内容在传输过程中没有被黑客拦截并修改过。许多企业虽然设定了邮件系统，但往往忽略了在 DNS 中发布 DKIM 记录，这会导致邮件在通过安全过滤器时“信誉分（Reputation）”大打折扣，最终掉进垃圾箱。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">最终的指令手册：DMARC 政策执行</h2><p>DMARC（Domain-based Message Authentication, Reporting, and Conformance）是邮件验证体系中最关键的一环。它是你写给收件方服务器的一份“指令手册”，告诉对方：如果一封自称来自我们公司的邮件，没有通过 SPF 或 DKIM 验证，你该怎么办？</p><p>DMARC 的设定有三个阶段：<br>第一个阶段是监控政策（p=none），这只是观察有多少冒名邮件，不会拦截。<br>第二个阶段是隔离政策（p=quarantine），这会将验证失败的邮件送入垃圾箱。<br>第三个阶段是拒绝政策（p=reject），这会直接退回所有验证失败的伪造邮件。</p><p>如果你的公司完全没有设定 DMARC 记录，现代的邮件系统会认为你的域名缺乏管理，这是在 2024 年后邮件被标记为 SPAM 的最常见原因。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">为什么现在修复这些问题刻不容缓</h2><p>网络诈骗与钓鱼邮件（Phishing）在全球泛滥，黑客常利用伪造的发送人名称来进行诈骗。为了保护用户，国际各大邮件供应商已经不再信任“没有身份证明”的电子邮件。</p><p>对于香港企业而言，这不仅是技术问题，更是“品牌信任”的问题。如果你的销售团队寄出的报价单一直出现在客户的垃圾箱，这代表你的域名信誉正在受损。长此以往，你的域名可能会被列入全球黑名单（Blacklist），到那时要重新恢复信誉，将需要花费数月甚至更长的时间与更高的金钱成本。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">IT 管理者的行动指南：如何检测与修复</h2><p>要解决邮件掉进垃圾箱的问题，IT 部门或委托的资安服务商应采取以下步骤：</p><p>第一步：使用专业工具进行域名诊断。你可以利用网上的免费工具如 mxtoolbox 或 dmarcian，输入你的公司域名，检查 SPF、DKIM 与 DMARC 是否已经正确部署。</p><p>第二步：清理过时的授权记录。移除那些不再使用的第三方邮件服务商（例如旧的电子报发送系统），确保 SPF 记录简洁且有效。</p><p>第三步：逐步实施 DMARC。建议先从 p=none 政策开始，收集一到两个月的报告，确认所有合法的业务邮件（包括 ERP、HR 系统发出的邮件）都已正确验证后，再提升到 p=quarantine 或 p=reject 政策，从根本上杜绝冒名邮件。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">让你的商业通讯回归正轨</h2><p>电子邮件验证虽然技术细节繁多，但其核心目标是建立“数字信任”。当你的公司正确配置了 SPF、DKIM 与 DMARC，你就像是为每一封邮件都贴上了官方的“防伪标签”。</p><p>这不仅能确保你的邮件 100% 准确送达客户的收件箱，更能防止黑客冒充你的公司向客户发出诈骗邮件。在竞争激烈的商业环境中，确保通讯渠道的畅通与安全，是每一家企业都必须打好的基础。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">强化企业安全 🛡️ 立即行动</h2><p style="text-align:center;">UD 是值得信赖的託管安全服务供应商（MSSP）<br>拥有 20+ 年经验，已为超过 50,000 家企业提供解决方案<br>涵盖渗透测试、漏洞扫描、SRAA 等全方位网络安全服务，全面保护现代企业。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">马上谘询资安专家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">为企业进行渗透测试</a></div><p>&nbsp;</p><p>&nbsp;</p>

<p>As the Hong Kong Monetary Authority (HKMA) progressively implements the Open API Framework, the banking sector in Hong Kong has transitioned from closed systems to an interconnected ecosystem. Open APIs allow banks to collaborate with Third-party Service Providers (TSPs) to offer more flexible financial products, but this simultaneously expands the attack surface of the bank. From the HKMA's regulatory perspective, the security of APIs is directly linked to the stability of the financial system. Therefore, high-standard penetration testing for Open API systems has become a top priority for compliance among Authorized Institutions (AIs).</p><p>The HKMA requires banks not only to conduct rigorous testing before launching APIs but also to maintain dynamic security defenses throughout the entire lifecycle. Understanding the regulator's specific expectations for testing frequency and technical depth can help banks find the optimal balance between innovation and compliance.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Financial Openness Under Digital Transformation: The Security Foundation of HKMA's Open API Framework</h2><p>The HKMA's Open API Framework divides APIs into four phases, ranging from initial product information inquiries to high-risk operations involving personal data and account transactions. As the phases progress, security requirements increase exponentially. In the HKMA's regulatory guidelines, Open APIs are considered part of critical information infrastructure and must be integrated into the bank's overall Cyber Resilience Assessment Framework (C-RAF).</p><p>For banks, the primary security challenge of Open APIs is the exposure of internal business logic. Attackers no longer need to breach firewalls; they can attempt to find authentication flaws or data leak vulnerabilities through legitimate API calls. Consequently, the HKMA expects banks to establish an active testing mechanism that goes beyond basic defense to ensure that customer privacy and assets are absolutely protected during the data-sharing process.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Testing Frequency in a Dynamic Environment: Defining HKMA-Recognized Regular Reviews</h2><p>Regarding the frequency of penetration testing, the HKMA does not adopt a single fixed standard but instead emphasizes a "risk-based" approach. For Phase 3 and Phase 4 APIs, which handle personal data and financial transactions, regulatory expectations are typically much stricter.</p><p>The baseline requirement is a comprehensive penetration test performed annually. This ensures that new threat vectors emerging over the past year do not pose a risk to existing API interfaces. However, a simple annual test is often insufficient for rapidly iterating development environments.</p><p>Additional targeted testing must be triggered when major changes occur. These changes include significant modifications to API logic, adjustments to authentication mechanisms (such as OAuth 2.0 flows), or migrations of infrastructure (such as cloud API gateways). The HKMA expects banks to integrate penetration testing into the development lifecycle (DevSecOps), ensuring that any change potentially affecting security is validated by a professional testing team before going live.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Beyond Surface Vulnerabilities: Deep Penetration of Open API Business Logic and Authentication</h2><p>In terms of technical depth, the penetration testing expected by the HKMA should go far beyond basic automated scanning. Testing must simulate specialized attack methods targeted at API characteristics.</p><p>A core focus is the deep testing of authentication and authorization logic. This includes verifying whether tokens in the OAuth flow are vulnerable to hijacking or forgery, and checking for Broken Function Level Authorization (BFLA) or Broken Object Level Authorization (BOLA). These vulnerabilities allow attackers to gain unauthorized access to other customers' account data by modifying parameters in API requests—a high-priority risk in HKMA audits.</p><p>Another requirement for depth is the integrity of data input and filtering mechanisms. The testing team needs to simulate various injection attacks to verify that API gateways and back-end services effectively filter malicious code. Furthermore, testing the rate limiting and Distributed Denial of Service (DDoS) resistance of APIs is crucial to ensure that critical financial services remain available even when facing a high volume of malicious calls.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Ecosystem Cybersecurity Defense: Technical Audit Responsibilities for TSPs</h2><p>The security of Open APIs depends not only on the bank itself but also on the security standards of Third-party Service Providers (TSPs). The HKMA explicitly requires banks to bear ultimate responsibility for outsourcing management and third-party risk management.</p><p>When integrating with TSPs, banks must review the security posture of the partner. This typically means banks will require TSPs to provide penetration test reports for their own systems. The HKMA expects banks to establish evaluation criteria to ensure that TSPs do not become a vulnerability point for the bank's network due to their own security flaws when calling APIs.</p><p>Additionally, banks should continuously monitor the API usage behavior of TSPs. Penetration testing should include simulations of "malicious or compromised TSP" scenarios to test whether the bank's API monitoring system can detect abnormal data scraping or unusual API call frequencies in real-time. This deep validation of ecosystem security is a core manifestation of supply chain risk management within C-RAF 2.0.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Building a Resilience Loop: Closed-loop Management from Discovery to Retesting</h2><p>The HKMA places great importance on the rigor of the remediation process during regulatory reviews. Finding a vulnerability is only the beginning; true compliance is demonstrated through the effective resolution of those vulnerabilities.</p><p>Authorized Institutions must establish a strict remediation timeline. For "Critical" or "High" risk vulnerabilities found during penetration testing, banks should complete remediation within a very short period and implement temporary compensatory controls to mitigate risk. The HKMA generally does not accept high-risk items that remain unpatched for long periods without a powerful business justification and mitigation measures.</p><p>Finally, there is the necessity of a Retest. Any remediation work must be independently validated by the original testing team. The retest must confirm not only that the vulnerability has been closed but also that the remediation process has not introduced new instabilities.

<p>随着金管局逐步推进开放 API（Open API）框架，香港的银行业已从封闭系统走向互联生态。开放 API 让银行能与第三方服务供应商（TSPs）合作，提供更灵活的金融产品，但这同时也扩大了银行的攻击面。在金管局的监管视角下，API 的安全性直接关系到金融体系的稳定。因此，针对 Open API 系统进行高标准的渗透测试，已成为认可机构合规工作的重中之重。</p><p>金管局不仅要求银行在 API 推出前进行严格测试，更强调在整个生命周期中维持动态的安全防御。理解监管机构对测试频率与技术深度的具体预期，能帮助银行在创新与合规之间取得最佳平衡。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">数码转型下的金融开放：金管局 Open API 框架的资安基石</h2><p>金管局的开放 API 框架将 API 分为四个阶段，从最初的产品资讯查询到涉及个人资料与账户交易的高风险操作。随着阶段的推进，安全要求也呈指数级增长。在金管局的监管指引中，开放 API 被视为关键信息基础设施的一部分，必须纳入银行的整体网络韧性评估框架（C-RAF）中。</p><p>对于银行而言，开放 API 的安全性挑战在于其暴露了内部的业务逻辑。黑客不再需要攻破防火墙，而是可以透过合法的 API 调用，尝试寻找身份验证缺陷或数据泄漏漏洞。因此，金管局期望银行建立一套超越基础防御的主动测试机制，以确保在数据开放的过程中，客户的隐私与资产得到绝对保障。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">动态环境下的测试频率：如何定义金管局认可的定期检核</h2><p>关于渗透测试的频率，金管局并非采用单一的固定标准，而是强调“风险导向（Risk-based）”的测试频率。对于处理个人资料及金融交易的第三及第四阶段 API，监管期望通常更为严格。</p><p>基本基准要求是每年进行一次全面的渗透测试。这是为了确保在过去一年中新出现的威胁手段，不会对现有的 API 接口造成威胁。然而，单纯的年度测试往往不足以应对快速迭代的开发环境。</p><p>在重大变动发生时，必须触发额外的针对性测试。这些变动包括 API 逻辑的大幅修改、身份认证机制（如 OAuth 2.0 流程）的调整，或是基础设施（如云端 API 网关）的迁移。金管局期望银行能将渗透测试整合进开发生命周期（DevSecOps）中，确保任何可能影响安全性的变更在正式上线前，都经过了专业测试团队的验证。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">超越表面漏洞：针对 Open API 业务逻辑与认证机制的深度渗透</h2><p>在技术深度方面，金管局期望的渗透测试应远远超越基础的自动化扫描。测试必须模拟黑客针对 API 特性的专门攻击方式。</p><p>核心重点之一是身份验证与授权逻辑的深度测试。这包括验证 OAuth 流程中的权标（Token）是否容易被劫持或伪造，以及是否存在“失效的功能级授权（BFLA）”或“失效的对象级授权（BOLA）”。这类漏洞能让黑客通过修改 API 请求中的参数，越权访问其他客户的账户数据，是金管局审计中最关注的风险点。</p><p>另一个深度要求是数据输入的完整性与过滤机制。测试团队需要模拟各类注入攻击，验证 API 网关与后端服务是否能有效过滤恶意代码。此外，针对 API 的频率限制（Rate Limiting）与抗阻断服务（DDoS）能力测试也至关重要，以确保系统在面临大量恶意调用时，依然能维持关键金融服务的可用性。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">生态系统的安全联防：第三方服务供应商 TSPs 的技术审核责任</h2><p>开放 API 的安全性不仅取决于银行自身，更取决于第三方供应商（TSPs）的安全水平。金管局明确要求银行在外包管理与第三方风险管理上承担最终责任。</p><p>银行在与 TSPs 对接时，必须审查对方的资安状况。这通常意味着银行会要求 TSPs 提供其自身系统的渗透测试报告。金管局期望银行能建立一套评估标准，确保 TSPs 在调用 API 时，不会因为其自身的安全缺陷而成为银行网络的漏洞点。</p><p>此外，银行应对 TSPs 的 API 使用行为进行持续监控。渗透测试应包含模拟“恶意或受损的 TSP”场景，测试银行的 API 监控系统是否能即时侦察到非正常的数据库抓取行为或异常的 API 调用频率。这种对生态系统安全性的深度验证，是 C-RAF 2.0 中关于供应链风险管理的核心体现。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">构建韧性循环：从漏洞发现到复测验证的闭环管理</h2><p>金管局在监管审查中极为重视修补流程的严谨性。发现漏洞只是测试的起点，真正的合规体现在如何有效地解决这些漏洞。</p><p>认可机构必须建立一套严格的修补时间表。对于渗透测试中发现的“严重”或“高”风险漏洞，银行应在极短的时间内完成修复，并采取临时补偿控制措施以降低风险。金管局通常不接受长期未修补的高风险项目，除非有极其强大的业务理由与缓解措施。</p><p>最后是复测（Retest）的必要性。任何修补工作都必须由原测试团队进行独立验证。复测不仅要确认漏洞已被堵塞，还要确保修补过程没有引入新的不稳定性。透过这种发现、修补、验证的闭合管理，银行可以向金管局证明其具备持续改善安全状况的能力，从而在开放银行的浪潮中保持稳健经营。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">强化企业安全 🛡️ 立即行动</h2><p style="text-align:center;">UD 是值得信赖的託管安全服务供应商（MSSP）<br>拥有 20+ 年经验，已为超过 50,000 家企业提供解决方案<br>涵盖渗透测试、漏洞扫描、SRAA 等全方位网络安全服务，全面保护现代企业。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">马上谘询资安专家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">为企业进行渗透测试</a></div><p>&nbsp;</p><p>&nbsp;</p>

<p>隨著金管局逐步推進開放 API（Open API）框架，香港的銀行業已從封閉系統走向互聯生態。開放 API 讓銀行能與第三方服務供應商（TSPs）合作，提供更靈活的金融產品，但這同時也擴大了銀行的攻擊面。在金管局的監管視角下，API 的安全性直接關係到金融體系的穩定。因此，針對 Open API 系統進行高標準的滲透測試，已成為認可機構合規工作的重中之重。</p><p>金管局不僅要求銀行在 API 推出前進行嚴格測試，更強調在整個生命週期中維持動態的安全防禦。理解監管機構對測試頻率與技術深度的具體預期，能幫助銀行在創新與合規之間取得最佳平衡。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">數碼轉型下的金融開放：金管局 Open API 框架的資安基石</h2><p>金管局的開放 API 框架將 API 分為四個階段，從最初的產品資訊查詢到涉及個人資料與賬戶交易的高風險操作。隨著階段的推進，安全要求也呈指數級增長。在金管局的監管指引中，開放 API 被視為關鍵資訊基礎設施的一部分，必須納入銀行的整體網絡韌性評估框架（C-RAF）中。</p><p>對於銀行而言，開放 API 的安全性挑戰在於其暴露了內部的業務邏輯。黑客不再需要攻破防火牆，而是可以透過合法的 API 調用，嘗試尋找身份驗證缺陷或數據洩漏漏洞。因此，金管局期望銀行建立一套超越基礎防禦的主動測試機制，以確保在數據開放的過程中，客戶的隱私與資產得到絕對保障。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">動態環境下的測試頻率：如何定義金管局認可的定期檢核</h2><p>關於滲透測試的頻率，金管局並非採用單一的固定標準，而是強調「風險導向（Risk-based）」的測試頻率。對於處理個人資料及金融交易的第三及第四階段 API，監管期望通常更為嚴格。</p><p>基本基準要求是每年進行一次全面的滲透測試。這是為了確保在過去一年中新出現的威脅手段，不會對現有的 API 接口造成威脅。然而，單純的年度測試往往不足以應對快速迭代的開發環境。</p><p>在重大變動發生時，必須觸發額外的針對性測試。這些變動包括 API 邏輯的大幅修改、身份認證機制（如 OAuth 2.0 流程）的調整，或是基礎設施（如雲端 API 網關）的遷移。金管局期望銀行能將滲透測試整合進開發生命週期（DevSecOps）中，確保任何可能影響安全性的變更在正式上線前，都經過了專業測試團隊的驗證。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">超越表面漏洞：針對 Open API 業務邏輯與認證機制的深度滲透</h2><p>在技術深度方面，金管局期望的滲透測試應遠遠超越基礎的自動化掃描。測試必須模擬黑客針對 API 特性的專門攻擊方式。</p><p>核心重點之一是身份驗證與授權邏輯的深度測試。這包括驗證 OAuth 流程中的權標（Token）是否容易被劫持或偽造，以及是否存在「失效的功能級授權（BFLA）」或「失效的對象級授權（BOLA）」。這類漏洞能讓黑客透過修改 API 請求中的參數，越權訪問其他客戶的賬戶數據，是金管局審計中最關注的風險點。</p><p>另一個深度要求是數據輸入的完整性與過濾機制。測試團隊需要模擬各類注入攻擊，驗證 API 網關與後端服務是否能有效過濾惡意代碼。此外，針對 API 的頻率限制（Rate Limiting）與抗阻斷服務（DDoS）能力的測試也至關重要，以確保系統在面臨大量惡意調用時，依然能維持關鍵金融服務的可用性。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">生態系統的安全聯防：第三方服務供應商 TSPs 的技術審核責任</h2><p>開放 API 的安全性不僅取決於銀行自身，更取決於第三方供應商（TSPs）的安全水平。金管局明確要求銀行在外包管理與第三方風險管理上承擔最終責任。</p><p>銀行在與 TSPs 對接時，必須審查對方的資安狀況。這通常意味著銀行會要求 TSPs 提供其自身系統的滲透測試報告。金管局期望銀行能建立一套評估標準，確保 TSPs 在調用 API 時，不會因為其自身的安全缺陷而成為銀行網絡的漏洞點。</p><p>此外，銀行應對 TSPs 的 API 使用行為進行持續監控。滲透測試應包含模擬「惡意或受損的 TSP」場景，測試銀行的 API 監控系統是否能即時偵測到非正常的數據抓取行為或異常的 API 調用頻率。這種對生態系統安全性的深度驗證，是 C-RAF 2.0 中關於供應鏈風險管理的核心體現。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">構建韌性循環：從漏洞發現到複測驗證的閉環管理</h2><p>金管局在監管審查中極為重視修補流程的嚴謹性。發現漏洞只是測試的起點，真正的合規體現在如何有效地解決這些漏洞。</p><p>認可機構必須建立一套嚴格的修補時間表。對於滲透測試中發現的「嚴重」或「高」風險漏洞，銀行應在極短的時間內完成修複，並採取臨時補償控制措施以降低風險。金管局通常不接受長期未修補的高風險項目，除非有極其強大的業務理由與緩解措施。</p><p>最後是複測（Retest）的必要性。任何修補工作都必須由原測試團隊進行獨立驗證。複測不僅要確認漏洞已被堵塞，還要確保修補過程沒有引入新的不穩定性。透過這種發現、修補、驗證的閉環管理，銀行可以向金管局證明其具備持續改善安全狀況的能力，從而在開放銀行的浪潮中保持穩健經營。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">強化企業安全 🛡️ 立即行動</h2><p style="text-align:center;">UD 是值得信賴的託管安全服務供應商（MSSP）<br>擁有 20+ 年經驗，已為超過 50,000 家企業提供解決方案<br>涵蓋滲透測試、漏洞掃描、SRAA 等全方位網絡安全服務，全面保護現代企業。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/tc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">馬上諮詢資安專家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/tc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">為企業進行滲透測試</a></div><p>&nbsp;</p><p>&nbsp;</p>

HKMA Open API Security Strategy: Guide to Penetration Testing Frequency and Depth Requirements

香港 Open API 系统资安策略：金管局要求的渗透测试频率与深度指南

香港 Open API 系統資安策略：金管局要求的滲透測試頻率與深度指南

<p>As a global fintech hub, Hong Kong relies on the stability and security of its payment systems as the lifeblood of its economy. Whether participating in the Faster Payment System (FPS) or operating as a Stored Value Facility (SVF) licensee, entities must navigate the rigorous cybersecurity audits of the Hong Kong Monetary Authority (HKMA). With the implementation and updates of the Payment Systems and Stored Value Facilities Ordinance (PSSV), regulatory expectations have evolved from basic technical defense to holistic cyber resilience and corporate governance.</p><p>Passing an HKMA cybersecurity audit is not an overnight task; it requires the cultivation of a deep-seated security culture within daily operations. Many operators feel overwhelmed during audits due to a lack of understanding of the regulatory logic. This article deciphers the five core keys to passing an HKMA audit, helping businesses move from mere compliance to genuine resilience.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Key One: Establishing a Board-Level Cybersecurity Governance Framework</h2><p>Under HKMA audit standards, cybersecurity is no longer viewed as a technical issue isolated within the IT department; it is defined as a critical component of corporate governance. When auditors enter an institution, they often look first at the level of engagement from the Board of Directors and senior management, rather than firewall configurations.</p><p>Institutions must establish a clear accountability mechanism. The Board should be responsible for approving cybersecurity strategies and regularly receiving reports on the organization's security posture. A common point of failure in audits is the lack of a direct reporting line from the Chief Information Security Officer (CISO) to the Board, or Board members’ inability to understand how technical risks impact business operations.</p><p>Consequently, operators must prove they have a professional cybersecurity committee and clear budget and resource allocations to support continuous security improvements. During an audit, providing Board meeting minutes, risk appetite statements, and a clear accountability matrix serves as powerful evidence of strong governance.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Key Two: Implementing Layered Network Segmentation and Perimeter Defense</h2><p>Payment systems involve massive fund transfers and sensitive customer data, making them primary targets for cybercriminals. The HKMA places extreme importance on the effectiveness of network segmentation during technical audits.</p><p>Operators must demonstrate that their Cardholder Data Environment (CDE) or payment processing environment is strictly isolated from general office networks and development environments. This is not just a physical separation but a logical control. Auditors will verify if firewall rules follow the "Default Deny" principle and if micro-segmentation technologies are used to prevent lateral movement by attackers within the internal network.</p><p>Furthermore, the depth of perimeter defense is a focal point. This includes implementing Multi-Factor Authentication (MFA) for all remote access, deploying Intrusion Detection and Prevention Systems (IDS/IPS), and securing API interfaces. Operators should be ready to present network topology diagrams and rule audit records to prove their security perimeter is dynamically maintained rather than stagnant.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Key Three: Developing Real-Time Transaction Monitoring and Threat Detection</h2><p>For payment system operators, passive defense is no longer enough to counter modern attacks. The HKMA expects operators to possess proactive detection capabilities for anomalous behavior, encompassing both cyber threats and financial fraud.</p><p>During the audit, operators need to demonstrate the operational effectiveness of their Security Operations Center (SOC). This includes the completeness of log collection, the scientific basis of alert triggers, and the speed of the incident response team. Auditors may randomly select historical security incidents to verify if the institution followed established procedures for containment, documentation, and reporting.</p><p>Additionally, a real-time risk engine for payment transactions is a highlight. Operators should prove their systems can detect abnormal transaction patterns, such as high-value transfers in short periods or calls from unusual geographic locations. This deep defense, integrating security monitoring with business logic, is a core indicator of high-level maturity.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Key Four: Full-Lifecycle Encryption and Key Management for Data Assets</h2><p>Data is the core asset of a payment system, and protecting its confidentiality and integrity is the baseline for passing an audit. HKMA auditors will rigorously examine protection measures for data at rest, in transit, and in processing.</p><p>Operators must implement an end-to-end encryption strategy. Whether it is static data in a database or dynamic data transmitted over the internet, high-strength encryption algorithms must be used. A common audit trap is loose Key Management. If encryption keys are stored on the same server as the data, or if key rotation frequencies do not meet standards, it will be flagged as a major security deficiency.</p><p>Therefore, establishing strict Hardware Security Module (HSM) management protocols, implementing key lifecycle management, and conducting rigorous permission audits for personnel accessing sensitive data are the technical cornerstones. Clear encryption policy documents and key management logs are indispensable supporting materials during the audit.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Key Five: Independent Penetration Testing and Continuous Remediation Loops</h2><p>The HKMA strongly emphasizes the validation of security through an external lens. This means operators must regularly engage independent third-party firms to conduct Penetration Testing (PenTest) and Vulnerability Assessments.</p><p>The scope of testing should cover all payment-related systems, including mobile apps, API gateways, and internal core servers. Auditors look not only at the findings of the penetration test but also at the remediation process. If high-risk vulnerabilities identified in a report remain unpatched after six months, it will likely lead to an audit failure.</p><p>Operators need to demonstrate a "closed-loop" vulnerability management process: from discovery and assessment to remediation and final Retesting. During the audit, providing year-over-year comparison reports showing a decrease in system vulnerabilities and demonstrating the institution’s responsiveness to the latest threats, such as zero-day attacks, are critical steps in gaining auditor trust.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Strategy Summary: Viewing the Audit as a Competitive Advantage</h2><p>Passing an HKMA cybersecurity audit should not be viewed as a burden, but rather as an opportunity to enhance the reliability and market reputation of a payment system. When an operator meets the stringent regulatory requirements for governance, defense, monitoring, data protection, and technical testing, the resilience of its system has reached world-class standards.</p><p>Cybersecurity is a dynamic battlefield.

How Payment System Operators Can Pass an HKMA Cybersecurity Audit: 5 Core Keys

支付系统营运者如何通过金管局资安审计的五个核心关键

支付系統營運者如何通過金管局資安審計的五個核心關鍵

<p>In the landscape of cross-border payments and global financial communications, SWIFT is a critical infrastructure supporting international financial operations. To counter increasingly frequent financial crimes with nation-state threat characteristics, SWIFT launched the Customer Security Programme (CSP) and its core, the Customer Security Controls Framework (CSCF). For Authorized Institutions (AIs) operating in Hong Kong, satisfying SWIFT CSCF is not just a prerequisite for maintaining global messaging eligibility; it must be organically integrated with the Hong Kong Monetary Authority’s (HKMA) Cyber Resilience Assessment Framework (C-RAF 2.0).</p><p>For Chief Information Security Officers (CISOs) and Compliance Managers, the primary challenge is meeting both sets of standards simultaneously. While their origins and primary focuses differ, there is substantial overlap in technical implementation and risk management. Effective integration not only deepens a bank’s defense but also significantly reduces compliance costs and audit resource consumption.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">The Core Standards of International Payment Security: The Evolution of SWIFT CSCF</h2><p>SWIFT CSCF is an evolving dynamic standard designed to ensure that all users accessing the SWIFT network maintain a baseline level of security defense. The CSCF divides control objectives into mandatory and advisory categories.</p><p>One core requirement is environment protection. This mandates that institutions strictly isolate their SWIFT-related infrastructure, such as SWIFT interfaces and gateways, either physically or logically. This segregation is designed to prevent hackers from using the general office network as a springboard to infiltrate sensitive environments processing high-value transactions.</p><p>Another focal point is identity and access management. SWIFT mandates the implementation of Multi-Factor Authentication (MFA) for all users accessing the SWIFT zone. Furthermore, privileged accounts with administrative rights must be subject to strict monitoring and auditing mechanisms. Additionally, SWIFT requires users to undergo an independent assessment annually, meaning that self-attestations must be verified by an independent third party or an internal audit team not involved in daily operations.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Where Local Regulation Meets Global Standards: Resonance Between C-RAF and SWIFT</h2><p>The C-RAF 2.0 launched by the HKMA is the cornerstone of local financial regulation. While its assessment target is the overall business of a bank, its protection of critical infrastructure shares striking similarities with the SWIFT CSCF.</p><p>The first major overlap lies in network segmentation. SWIFT defines a "Secure Zone," and the HKMA also emphasizes the importance of network segmentation within the "Protect" domain of C-RAF. For Hong Kong banks, building a network architecture that meets C-RAF’s high maturity requirements usually satisfies most of SWIFT’s environmental isolation requirements automatically.</p><p>The second overlap is vulnerability management and technical testing. SWIFT requires users to perform regular vulnerability assessments. Meanwhile, the HKMA requires Intelligence-led Cyber Attack Simulation Testing (iCAST) under C-RAF. In practice, iCAST testing scenarios often include simulated attacks on payment systems like SWIFT or FPS. This means a high-quality iCAST report can be used to demonstrate a bank’s defensive resilience within the SWIFT environment.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Integrated Strategies for Dual Compliance: Enhancing Execution Efficiency</h2><p>Facing multiple regulatory requirements, institutions should not adopt a siloed approach to compliance. Integrated execution is the optimal solution.</p><p>An effective strategy is to establish a unified control matrix. The security team should precisely map each SWIFT CSCF control point to the C-RAF maturity indicators. Through this mapping, institutions can clearly identify which controls serve both purposes. For example, implementing a robust Privileged Access Management (PAM) system across the entire bank can address identity management requirements in both frameworks simultaneously.</p><p>Synchronizing audit and testing cycles is also key to efficiency. When scheduling annual Penetration Tests (PenTest), institutions should require the testing team to include SWIFT security controls in the scope. The resulting report can then serve as technical evidence for the HKMA while supporting the self-attestation for the SWIFT annual independent assessment. This approach minimizes disruption to operational departments and ensures consistency in technical testing.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Common Technical Challenges and Solutions During Execution</h2><p>Despite clear objectives, Hong Kong financial institutions often encounter technical and administrative obstacles during execution.</p><p>The primary challenge is the integration of legacy systems. Many established banks still use older SWIFT interfaces that may not support modern MFA solutions. In such cases, institutions should consider introducing security proxy technologies or implementing stricter micro-segmentation at the network layer to compensate for authentication deficiencies in older systems.</p><p>Another pain point is third-party supply chain risk. Many banks outsource their SWIFT infrastructure to technology vendors. In these scenarios, banks must explicitly require in their contracts that vendors regularly submit third-party audit reports or penetration test evidence. Ensuring that the vendor’s internal controls stay synchronized with the SWIFT CSCF is a key risk management focus repeatedly emphasized by the HKMA in its outsourcing guidelines (TM-G-1).</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">The Strategic Value of Independent Assessment: Ensuring Genuine Cyber Resilience</h2><p>Since SWIFT introduced mandatory independent assessments, the barrier to compliance has risen significantly. Banks can no longer simply check off compliance boxes; they must provide solid technical evidence.</p><p>In Hong Kong, selecting a professional cybersecurity consultancy with extensive experience in HKMA assessments is vital. Expert consultants do more than just help institutions complete the SWIFT checklist; they evaluate a bank’s survival capability against real-world hackers from the perspective of "cyber resilience." This assessment is not just about meeting regulatory requirements—it is about protecting the bank’s assets and reputation.</p><p>Cybersecurity is a dynamic battlefield. The overlap between SWIFT CSCF and Hong Kong’s cybersecurity requirements provides an excellent opportunity for financial institutions to consolidate their infrastructure.

<p>在跨境支付与全球金融通讯领域，SWIFT 是支撑全球金融运作的核心基础设施。为了应对日益猖獗且具备国家级威胁特征的金融犯罪，SWIFT 推出了“客户安全计划（CSP）”及其核心的“客户安全控制框架（CSCF）”。对于在香港运营的认可机构而言，满足 SWIFT CSCF 不仅是维持全球通讯资格的必要条件，更必须与香港金融管理局（HKMA）的“网络韧性评估框架（C-RAF 2.0）”进行有机整合。</p><p>对于资安长与合规经理来说，最大的挑战在于如何同时满足这两套标准。虽然两者的来源与初衷不同，但在技术实施与风险管控层面存在大量重叠。有效地整合执行，不仅能提升银行的防御深度，更能大幅节省合规成本与审计资源。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">国际支付安全的核心准则：SWIFT CSCF 演进</h2><p>SWIFT CSCF 是一套不断演进的动态标准，旨在确保所有接入 SWIFT 网络的用户都能维持基准水平的安全防御。CSCF 划分了多个控制目标，并将其分为强制性与建议性控制。</p><p>核心要求之一是保护环境。这要求机构必须对其 SWIFT 相关的基础设施（如 SWIFT 界面与网关）进行严格的物理或逻辑隔离。这种隔离旨在防止黑客通过普通的办公网络作为跳板，进而渗透到处理高额交易的敏感环境中。</p><p>另一项重点是身份与访问管理。SWIFT 强制要求对所有访问 SWIFT 区域的用户实施多因素认证（MFA）。同时，对于拥有管理权限的特权账号，必须有严格的监控与审核机制。此外，SWIFT 也要求用户每年进行一次独立评估，这意味着自我声明必须经过不参与日常运营的独立第三方或内部审计团队的验证。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">本地监管与全球标准的交汇点：C-RAF 与 SWIFT 的共鸣</h2><p>香港金管局推出的 C-RAF 2.0 是本地金融监管的基石。虽然其评估对象是银行的整体业务，但在针对关键基础设施的保护上，与 SWIFT CSCF 有着惊人的相似性。</p><p>两者的第一个重要重叠在于网络分段。SWIFT 定义了“安全区域（Secure Zone）”，而金管局在 C-RAF 的保护范畴中也强调了网络分段的重要性。对于香港银行而言，建立一套符合 C-RAF 高成熟度要求的网络架构，通常就已经自动满足了 SWIFT 对于环境隔离的大部分要求。</p><p>第二个重叠点是漏洞管理与技术测试。SWIFT 要求用户定期进行漏洞评估。而金管局则在 C-RAF 下要求进行情报主导的攻击模拟测试（iCAST）。事实上，iCAST 的测试场景往往会包含对支付系统（如 SWIFT 或 FPS）的模拟攻击。这意味着一份高品质的 iCAST 测试报告，完全可以用来证明银行在 SWIFT 环境下的防御韧性。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">实施双重合规的整合策略：如何提升执行效率</h2><p>面对多重监管要求，机构不应采取孤岛式的合规方法。整合执行才是最优解。</p><p>有效的策略是建立统一的控制矩阵。资安团队应将 SWIFT CSCF 的每一项控制点，与 C-RAF 的成熟度指标进行精确对接。通过这种对接，机构可以清晰地看到哪些控制措施是“一箭双雕”的。例如，在全行范围内推行严格的特权访问管理（PAM）系统，可以同时解决两套标准中关于身份管控的要求。</p><p>同步审计与测试周期也是提升效率的关键。机构在安排年度渗透测试（PenTest）时，应要求测试团队将 SWIFT 的安全控制纳入测试范围。这样产出的报告，既能作为金管局要求的技术证明，也能支持 SWIFT 年度独立评估的自我声明。这种做法不仅减少了对运营部门的干扰，也确保了技术测试的一致性。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">执行过程中常见的技术挑战与应对之道</h2><p>尽管目标明确，但在实际执行中，香港金融机构常会遇到技术与管理上的障碍。</p><p>首要挑战是遗留系统的集成。许多历史悠久的银行仍在使用较旧的 SWIFT 接口，这些系统可能不支持现代的 MFA 方案。对此，机构应考虑引入中间层的安全代理技术，或在网络层面实施更严格的微隔离（Micro-segmentation），以补偿旧系统在身份验证上的不足。</p><p>另一个痛点是第三方供应链风险。许多银行将其 SWIFT 基础设施委托给技术供应商代管。在这种情况下，银行必须在合同中明确要求供应商定期提交第三方审计报告或渗透测试证明，并确保供应商的内部管控与 SWIFT CSCF 保持同步。这也是金管局在外包指引（TM-G-1）中反复强调的风险管理重点。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">独立评估的战略价值：确保真实的网络韧性</h2><p>自从 SWIFT 引入强制性独立评估以来，合规的门槛显著提高。银行不能再只是简单地勾选合规选项，而是需要提供扎实的技术证据。</p><p>在香港，选择一家具备丰富金管局评核经验的专业资安顾问公司至关重要。专业的顾问不仅能帮助机构完成 SWIFT 的清单检查，更能站在“网络韧性”的高度，评估银行在面对真实黑客攻击时的生存能力。这种评估不仅是为了符合监管要求，更是为了保护银行的资产安全与声誉。</p><p>网络安全是一个动态的战场。SWIFT CSCF 与香港资安要求的重叠，为金融机构提供了一个巩固基础设施的绝佳机会。通过深入理解这些标准的内在联系，并采取整合性的执行策略，香港的金融机构可以在全球数码化的浪潮中，建立起一套既合规又强大的网络安全防御体系。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">强化企业安全 🛡️ 立即行动</h2><p style="text-align:center;">UD 是值得信赖的託管安全服务供应商（MSSP）<br>拥有 20+ 年经验，已为超过 50,000 家企业提供解决方案<br>涵盖渗透测试、漏洞扫描、SRAA 等全方位网络安全服务，全面保护现代企业。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">马上谘询资安专家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">为企业进行渗透测试</a></div><p>&nbsp;</p><p>&nbsp;</p>

<p>在跨境支付與全球金融通訊的領域中，SWIFT 是支撐全球金融運作的核心基礎設施。為了應對日益頻繁且具備國家級威脅特徵的金融犯罪，SWIFT 推出了「客戶安全計劃（CSP）」及其核心的「客戶安全控制框架（CSCF）」。對於在香港營運的認可機構而言，滿足 SWIFT CSCF 不僅是維持全球通訊資格的必要條件，更必須與香港金融管理局（HKMA）的「網絡韌性評估框架（C-RAF 2.0）」進行有機整合。</p><p>對於資安長與合規經理來說，最大的挑戰在於如何同時滿足這兩套標準。雖然兩者的來源與初衷不同，但在技術實施與風險管控層面存在大量重疊。有效地整合執行，不僅能提升銀行的防禦深度，更能大幅節省合規成本與審計資源。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">國際支付安全的核心準則：SWIFT CSCF 演進</h2><p>SWIFT CSCF 是一套不斷演進的動態標準，旨在確保所有接入 SWIFT 網絡的用戶都能維持基準水平的安全防禦。CSCF 劃分了多個控制目標，並將其分為強制性與建議性控制。</p><p>核心要求之一是保護環境。這要求機構必須對其 SWIFT 相關的基礎設施（如 SWIFT 介面與網關）進行嚴格的物理或邏輯隔離。這種隔離旨在防止黑客透過普通的辦公網絡作為跳板，進而滲透到處理高額交易的敏感環境中。</p><p>另一項重點是身份與存取管理。SWIFT 強制要求對所有存取 SWIFT 區域的使用者實施多因素認證（MFA）。同時，對於擁有管理權限的特權賬號，必須有嚴格的監控與審核機制。此外，SWIFT 也要求用戶每年進行一次獨立評估，這意味著自我聲明必須經過不參與日常營運的獨立第三方或內部審計團隊的驗證。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">本地監管與全球標準的交匯點：C-RAF 與 SWIFT 的共鳴</h2><p>香港金管局推出的 C-RAF 2.0 是本地金融監管的基石。雖然其評估對象是銀行的整體業務，但在針對關鍵基礎設施的保護上，與 SWIFT CSCF 有著驚人的相似性。</p><p>兩者的第一個重要重疊在於網絡分段。SWIFT 定義了「安全區域（Secure Zone）」，而金管局在 C-RAF 的保護範疇中也強調了網絡分段的重要性。對於香港銀行而言，建立一套符合 C-RAF 高成熟度要求的網絡架構，通常就已經自動滿足了 SWIFT 對於環境隔離的大部分要求。</p><p>第二個重疊點是漏洞管理與技術測試。SWIFT 要求用戶定期進行漏洞評估。而金管局則在 C-RAF 下要求進行情報主導的攻擊模擬測試（iCAST）。事實上，iCAST 的測試場景往往會包含對支付系統（如 SWIFT 或 FPS）的模擬攻擊。這意味著一份高品質的 iCAST 測試報告，完全可以用來證明銀行在 SWIFT 環境下的防禦韌性。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">實施雙重合規的整合策略：如何提升執行效率</h2><p>面對多重監管要求，機構不應採取孤島式的合規方法。整合執行才是最優解。</p><p>有效的策略是建立統一的控制矩陣。資安團隊應將 SWIFT CSCF 的每一項控制點，與 C-RAF 的成熟度指標進行精確對接。透過這種對接，機構可以清晰地看到哪些控制措施是「一石二鳥」的。例如，在全行範圍內推行嚴格的特權存取管理（PAM）系統，可以同時解決兩套標準中關於身份管控的要求。</p><p>同步審計與測試週期也是提升效率的關鍵。機構在安排年度滲透測試（PenTest）時，應要求測試團隊將 SWIFT 的安全控制納入測試範圍。這樣產出的報告，既能作為金管局要求的技術證明，也能支持 SWIFT 年度獨立評估的自我聲明。這種做法不僅減少了對運營部門的干擾，也確保了技術測試的一致性。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">執行過程中常見的技術挑戰與應對之道</h2><p>儘管目標明確，但在實際執行中，香港金融機構常會遇到技術與管理上的障礙。</p><p>首要挑戰是遺留系統的集成。許多歷史悠久的銀行仍在使用較舊的 SWIFT 接口，這些系統可能不支持現代的 MFA 方案。對此，機構應考慮引入中間層的安全代理技術，或在網絡層面實施更嚴格的微隔離（Micro-segmentation），以補償舊系統在身份驗證上的不足。</p><p>另一個痛點是第三方供應鏈風險。許多銀行將其 SWIFT 基礎設施委託給技術供應商代管。在這種情況下，銀行必須在合約中明確要求供應商定期提交第三方審計報告或滲透測試證明，並確保供應商的內部管控與 SWIFT CSCF 保持同步。這也是金管局在外包指引（TM-G-1）中反覆強調的風險管理重點。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">獨立評估的戰略價值：確保真實的網絡韌性</h2><p>自從 SWIFT 引入強制性獨立評估以來，合規的門檻顯著提高。銀行不能再只是簡單地勾選合規選項，而是需要提供紮實的技術證據。</p><p>在香港，選擇一家具備豐富金管局評核經驗的專業資安顧問公司至關重要。專業的顧問不僅能幫助機構完成 SWIFT 的清單檢查，更能站在「網絡韌性」的高度，評估銀行在面對真實黑客攻擊時的生存能力。這種評估不僅是為了符合監管要求，更是為了保護銀行的資產安全與聲譽。</p><p>網絡安全是一個動態的戰場。SWIFT CSCF 與香港資安要求的重疊，為金融機構提供了一個鞏固基礎設施的絕佳機會。透過深入理解這些標準的內在聯繫，並採取整合性的執行策略，香港的金融機構可以在全球數碼化的浪潮中，建立起一套既合規又強大的網絡安全防禦體系。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">強化企業安全 🛡️ 立即行動</h2><p style="text-align:center;">UD 是值得信賴的託管安全服務供應商（MSSP）<br>擁有 20+ 年經驗，已為超過 50,000 家企業提供解決方案<br>涵蓋滲透測試、漏洞掃描、SRAA 等全方位網絡安全服務，全面保護現代企業。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/tc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">馬上諮詢資安專家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/tc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">為企業進行滲透測試</a></div><p>&nbsp;</p><p>&nbsp;</p>

<p>As fintech continues to revolutionize the financial sector, the operations of brokerage and futures firms have become deeply intertwined with the internet. Over the past few years, the Securities and Futures Commission (SFC) of Hong Kong has repeatedly emphasized that cybersecurity is the heart of operational resilience for Licensed Corporations (LCs). Under the guidelines of "Baseline Cybersecurity Requirements," the security of online trading systems is no longer just a technical matter but a legal issue critical to licensing compliance.</p><p>For management, understanding the practical requirements of a Penetration Test (PenTest) is not just about passing an annual audit; it is about protecting customer assets and corporate reputation in an era of increasingly rampant cyberattacks. This article provides a deep dive into the core details LCs must master when executing penetration tests.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Cyber Threats Facing the Securities Industry and Regulatory Expectations</h2><p>Brokerages and futures firms process massive amounts of real-time trading data and client funds, making them prime targets for cybercriminals. In recent years, we have seen a continuous stream of sophisticated attacks against LCs, ranging from Credential Stuffing aimed at customer accounts to Distributed Denial of Service (DDoS) attacks on trading platforms and highly destructive ransomware.</p><p>The expectations of the SFC are clear: LCs must adopt rigorous technical and administrative measures to ensure system integrity. Penetration testing is regarded as one of the most effective methods of verification. By simulating the mindset of a hacker, LCs can discover and remediate security flaws in online trading systems, mobile apps, and internal networks before a real disaster strikes. It is not just about finding bugs; it is about validating the institution’s overall response and defense capabilities.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Core Scope and Technical Depth of Trading System Testing</h2><p>A compliant penetration test report must go beyond surface-level checks; it must dive deep enough to uncover architectural flaws. According to SFC regulatory principles, the testing scope should include several critical domains at a minimum.</p><p>The first domain is the security of front-end and mobile platforms. The testing team must simulate how an attacker might bypass Two-Factor Authentication (2FA), intercept API communications, or exploit vulnerabilities in mobile app code for privilege escalation. Since many brokers use third-party trading software, ensuring the developer has left no backdoors or debugging interfaces in the code is vital.</p><p>The second domain is the defense of back-end logic and databases. This involves testing for flaws in trading logic—for instance, whether an attacker can manipulate packets to change transaction prices or transfer funds belonging to others. Furthermore, ensuring that databases storing customer identity documents are shielded from SQL injection and other forms of data exfiltration is a top priority.</p><p>Finally, the perimeter security of the infrastructure must be assessed. This includes verifying the proper isolation between the general office network and the trading system environment. Hackers frequently compromise employee computers via phishing emails and use them as springboards to infiltrate trading servers. The penetration test must verify that such "lateral movement" is sufficiently difficult.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Standard Frequency and Professional Qualification Requirements</h2><p>A frequent question from LCs is: How often should we perform a penetration test?</p><p>While the SFC does not always mandate a rigid schedule for all scenarios, industry standards and regulatory expectations generally suggest a comprehensive penetration test at least once a year. Additionally, targeted testing is required whenever there is a major system update or architectural change (such as migrating to a cloud platform or replacing the core trading system) to ensure the changes have not introduced new risks.</p><p>Regarding the testing team's qualifications, the SFC expects LCs to engage independent and professional third-party organizations. The testing team should hold internationally recognized certifications such as OSCP or CREST, which guarantee technical proficiency. More importantly, the principle of independence is paramount: an LC's internal IT department should not conduct penetration tests on systems they maintain, as this creates a conflict of interest that compromises the objectivity of the report.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Effectively Managing Findings in a Penetration Test Report</h2><p>Upon completion of the test, the LC will receive a report listing all findings. How management handles this information is a key indicator of compliance sincerity.</p><p>The primary principle for managing findings is risk prioritization. Reports typically categorize vulnerabilities as "Critical," "High," "Medium," or "Low." LCs must prioritize the remediation of Critical and High-risk vulnerabilities. For these items, management should require the technical team or outsourcing developer to submit a remediation plan within a short, defined period—usually within 14 days.</p><p>The verification process after remediation is equally critical. Simply patching the code is insufficient; the LC must invite the original testing team to perform a "Retest." The purpose of the retest is twofold: first, to confirm that the original vulnerability has been properly closed; and second, to ensure that the patch itself has not affected other system functions or created new vulnerabilities. Only with a "Pass" in the retest is the compliance task officially completed.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Building a Sustainable and Dynamic Security Defense System</h2><p>Penetration testing should not be viewed as an annual chore; it should be integrated into the firm’s daily risk management processes. In a rapidly changing threat environment, static defense is never enough.</p><p>LCs should consider establishing a "Vulnerability Management Program," performing automated vulnerability scans regularly between annual penetration tests to identify newly surfaced security patches in real-time. Simultaneously, strengthening cybersecurity training for employees is essential to prevent human error from becoming the weakest link in the defense chain.</p><p>When an LC demonstrates this proactive defensive posture, it does more than just satisfy SFC audit requirements—it builds customer trust. In the securities industry, trust is the most valuable asset.

<p>随着金融科技的普及，证券行与期货经纪行的运营模式已与互联网深度链接。香港证券及期货事务监察委员会（SFC）在过去数年多次强调，网络安全是持牌法团运营韧性的核心。特别是在《网络安全基准要求》指引下，网上交易系统的安全性不再只是技术问题，而是关乎牌照合规的法律问题。</p><p>对于管理层而言，理解渗透测试（Penetration Test）的实质要求，不仅是为了应付年度审计，更是为了在日益猖獗的黑客攻击中，保护客户资产与公司名声。本文将深入剖析持牌法团在执行渗透测试时必须掌握的核心细节。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">证券业面临的网络威胁与监管机构的期待</h2><p>证券行与期货商处理着大量的实时交易数据与客户资金，这使其成为网络犯罪分子的首选目标。近年来，我们看到针对持牌法团的攻击手段层出不穷，包括冒充客户的凭证填充攻击（Credential Stuffing）、针对交易平台的阻断服务攻击（DDoS），以及更具破坏性的勒索软件。</p><p>证监会（SFC）的要求非常明确：持牌法团必须采取严谨的技术与管理措施，以确保其系统的完整性。渗透测试被视为一种最有效的验证手段。通过模拟黑客的攻击思维，持牌法团可以赶在真实灾难发生前，发现并修补网上交易系统、移动应用程序及内部网络中的安全缺陷。这不仅仅是检查漏洞，更是验证机构的整体应变与防御能力是否达标。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">网上交易系统渗透测试的核心范围与技术深度</h2><p>一份合规的渗透测试报告不能只覆盖系统的表面，它必须深入到足以发现架构层面的问题。根据 SFC 的监管精神，测试范围至少应包含以下关键领域。</p><p>首先是前端与移动端的安全性。测试团队需要模拟攻击者如何绕过双重认证（2FA）、拦截 API 通讯或是利用移动端 App 的代码漏洞进行提权。特别是现在许多券商使用第三方开发的交易软件，确保开发商在代码中没有留下后门或调试接口至关重要。</p><p>其次是后端逻辑与数据库的防护。这涉及测试交易逻辑是否存在缺陷，例如攻击者是否能通过篡改封包来修改交易价格或转移他人资金。同时，存放客户身份证明文件的数据库是否具备足够的防护措施，防止 SQL 注入攻击或其他形式的数据脱库行为，也是测试的重中之重。</p><p>最后是基础设施的边界安全。这包括检查办公室网络与交易系统环境之间是否有正确的隔离。黑客最常通过钓鱼邮件入侵员工电脑，再以员工电脑为跳板渗透进交易服务器。渗透测试必须验证这种“横向移动”的难度是否足够高。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">执行渗透测试的标准频率与专业资质要求</h2><p>持牌法团常问的一个问题是：我们应该多久做一次渗透测试？</p><p>虽然 SFC 没有在所有情况下规定死板的时间表，但业界标准与监管期望通常建议每年至少进行一次全面的渗透测试。此外，每当系统发生重大更新或架构变动时（例如迁移至云端平台、更换核心交易系统），也必须进行针对性的测试，以确保新变动没有引入新的安全风险。</p><p>关于执行团队的资质，SFC 期望持牌法团聘请具备独立性且专业的第三方机构。测试团队应持有国际认可的证书，例如 OSCP 或 CREST，这保证了测试的专业技术水平。更重要的是独立性原则，法团内部的 IT 部门不能对自己维护的系统进行渗透测试，因为这会产生利益冲突，难以保证报告的客观性。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">科学应对渗透测试报告中的发现与漏洞修补</h2><p>当测试完成后，持牌法团会收到一份列出所有发现（Findings）的报告。管理层应如何处置这些信息，是体现合规诚意的关键。</p><p>处理发现的首要原则是风险分级。报告通常会将漏洞分为“严重”、“高”、“中”、“低”四个等级。持牌法团必须优先处理严重与高风险的漏洞。对于这些漏洞，管理层应要求技术团队或外包开发商在规定的短时间内（通常为 14 天内）提交修补方案。</p><p>修补后的验证流程同样关键。单纯修补代码是不够的，持牌法团必须邀请原测试团队进行“复测”（Retest）。复测的目的在于确认两点：第一，原有的漏洞是否已被正确堵塞；第二，修补行为本身有没有影响系统的其他功能或产生新的漏洞。只有拿到“复测通过”的证明，这项合规工作才算正式告一段落。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">建立可持续的动态安全防御体系</h2><p>渗透测试不应被视为一年一度的苦差事，而应被整合进法团的日常风险管理流程中。在快速变化的威胁环境下，静态的防御是不够的。</p><p>持牌法团应考虑建立“漏洞管理计划”，在两次年度渗透测试之间，定期进行自动化的漏洞扫描，及时发现新出现的安全补丁。同时，加强对员工的网络安全培训，防止人为因素成为防御体系中最薄弱的一环。</p><p>当持牌法团展现出这种主动防御的态度时，不仅能满足 SFC 的审计要求，更能建立客户的信任。在证券行业，信任就是最宝贵的资产。通过严谨的渗透测试与持续的安全投入，持牌法团可以在变幻莫测的数码市场中，行稳致远。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">强化企业安全 🛡️ 立即行动</h2><p style="text-align:center;">UD 是值得信赖的託管安全服务供应商（MSSP）<br>拥有 20+ 年经验，已为超过 50,000 家企业提供解决方案<br>涵盖渗透测试、漏洞扫描、SRAA 等全方位网络安全服务，全面保护现代企业。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">马上谘询资安专家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">为企业进行渗透测试</a></div><p>&nbsp;</p><p>&nbsp;</p>

SFC Licensed Corporations Guide: Compliance for Online Trading System Penetration Testing

SFC 持牌法团必读：网上交易系统渗透测试的合规执行手册

SFC 持牌法團必讀：網上交易系統滲透測試的法規遵從手冊

<p>In the current global financial landscape, cybersecurity has transitioned from being a purely technical concern to a cornerstone of enterprise governance and regulatory compliance. The Hong Kong Monetary Authority (HKMA), as the primary regulator of the banking sector, is committed to maintaining the stability and integrity of Hong Kong as an international financial center. Under the overarching Cyber Fortification Initiative (CFI), the Cyber Resilience Assessment Framework (C-RAF) sets a rigorous and forward-looking benchmark for the industry.</p><p>With the evolution to C-RAF 2.0, regulatory requirements have become more granular and technically demanding. For Authorized Institutions (AIs), mastering the execution of penetration testing and attack simulation is no longer optional—it is a prerequisite for licensing compliance and business continuity. This article provides an in-depth analysis of the C-RAF 2.0 technical and regulatory requirements, serving as a comprehensive execution guide for financial institutions.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Why C-RAF 2.0 is a Turning Point for Hong Kong Banking</h2><p>In traditional security audit models, most institutions adopted a passive "compliance-based" defense. As long as an institution could prove it had firewalls, encryption, and an annual scan, it generally passed the audit. However, with the rise of ransomware, supply chain attacks, and nation-state threat actors targeting financial systems, the HKMA recognized that simple "protection" is no longer sufficient.</p><p>The core philosophy of C-RAF 2.0 is "Cyber Resilience." This concept focuses on the reality that "an attack will eventually occur." Therefore, the framework no longer just checks if the doors are locked. Instead, it requires banks to prove that if an attacker enters the internal network, the bank has the monitoring capabilities to detect the intrusion, the responsiveness to contain the damage, and the ability to recover core business functions in the shortest possible time.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">A Deep Dive into the Three Pillars of C-RAF 2.0</h2><p>To achieve full compliance with C-RAF 2.0, AIs must complete a three-phase assessment process. Penetration testing plays a distinct role in each phase.</p><p>Pillar One: Inherent Risk Assessment (IRA)<br>This is the starting point. Banks perform a self-assessment based on business activities, product complexity, technical environment, and reliance on outsourcing. Based on the score, banks are categorized into Low, Medium, or High inherent risk levels. The higher the risk level, the more stringent the requirements for penetration testing frequency and depth.</p><p>Pillar Two: Maturity Assessment (MA)<br>In this phase, banks evaluate their actual performance across five domains: Identify, Protect, Detect, Respond, and Recover. This is not just a document review. Banks must provide technical evidence. For instance, an institution must prove its detection mechanisms can identify anomalous traffic, which is typically verified through internal vulnerability scans and security testing.</p><p>Pillar Three: Intelligence-led Cyber Attack Simulation Testing (iCAST)<br>This is the most technically advanced part of C-RAF 2.0. For institutions with Medium or High inherent risk, iCAST is mandatory. Unlike traditional penetration testing, iCAST is a threat-intelligence-based red teaming exercise. It requires testers to simulate the actual Tactics, Techniques, and Procedures (TTPs) used by real-world threat actors to attack the bank's critical infrastructure.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Technical Differences: Penetration Testing vs. iCAST</h2><p>It is common for executive management to confuse traditional penetration testing with iCAST. Understanding the difference is vital for budgeting and vendor selection.</p><p>The primary goal of Traditional Penetration Testing is "vulnerability discovery." Testers attempt to exploit specific systems to find unpatched code, misconfigurations, or weak credentials. It is usually targeted and narrow in scope, focusing on ensuring the security of the system itself.</p><p>In contrast, iCAST is "objective-oriented" and "threat-led." The process involves three stages. First is the "Threat Intelligence Phase," where a specialized team identifies which hacker groups are targeting the HK banking sector and their preferred attack vectors. Second is the "Scenario Development Phase," where specific attack paths are designed for the bank, such as entering the network through a spoofed vendor email. Finally, in the "Execution Phase," Red Teamers launch the attack without notifying the bank’s defense team (Blue Team) to test real-time detection and response.</p><h2 class="green-h2" style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Critical Compliance Details for C-RAF 2.0 Testing</h2><p>When preparing for C-RAF testing, AIs must ensure they adhere to several key compliance standards to ensure the HKMA recognizes the reports.</p><p>Point One: Professional Qualifications and Independence<br>The HKMA places high value on the expertise of the testing team. AIs should engage third-party firms with international certifications, such as CREST (Certified Registered Ethical Security Testers). Furthermore, independence is mandatory. Vendors involved in the development or maintenance of a system cannot serve as the penetration testers for that same system.</p><p>Point Two: Comprehensive Scope Coverage<br>Compliant penetration testing cannot be limited to external web portals. According to C-RAF principles, the scope must cover core banking systems, Swift gateways, online and mobile banking apps, internal Active Directory servers, and all API interfaces connecting to third-party providers.</p><p>Point Three: Remediation and Closed-loop Management<br>Receiving the report is only half the battle. AIs must develop a detailed remediation plan based on the risk rankings (Critical, High, Medium, Low). High-risk vulnerabilities usually require immediate patching within a timeframe specified by the regulator. After patching, a "Retest" must be performed by the third-party team to verify the resolution, and this retest report must be archived as part of the final compliance documentation.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Why Some Banking Audits Fail</h2><p>Based on industry experience, common reasons for failure during a C-RAF assessment include:</p><p>Reason One: Incomplete data asset inventory. The bank cannot accurately identify its "Critical Information Assets," leading to blind spots in penetration testing coverage.</p><p>Reason Two: Underestimating third-party risk. While the bank’s own defenses may be robust, connections with outsourced technical providers often have serious security flaws that hackers exploit as a springboard.</p><p>Reason Three: Lack of continuous monitoring. Many institutions perform well during the test period but lack automated vulnerability management once the test concludes and new configurations or vulnerabilities emerge.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">How to Prepare for a Successful C-RAF 2.0 Assessment</h2><p>To ensure a smooth process and meet regulatory standards, we recommend the following steps:</p><p>Step One: Conduct a pre-assessment and gap analysis. Six months before the formal C-RAF assessment, hire consultants to perform a mock audit to identify maturity gaps and remediate them in advance.</p><p>Step Two: Enhance threat intelligence capabilities. For institutions requiring iCAST, establish partnerships with intelligence-capable vendors early to understand the latest attack trends in the industry.</p><p>Step Three: Establish cross-departmental collaboration. Penetration testing is not just an IT task. Compliance, Risk Management, and even Business Units should be involved to ensure the testing scope aligns with actual business operations.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Turning Compliance into Enterprise Trust</h2><p>In Hong Kong's highly competitive financial market, the sense of security customers feel regarding digital services is a vital component of brand value.

<p>在当前全球金融环境中，网络安全已不再仅仅是资讯科技部门的责任，而是上升到了企业管治与合规经营的核心层面。香港金融管理局（HKMA）作为香港银行业的监管者，一直致力于维护香港国际金融中心的稳定性。在「网络防卫计划（Cyber Fortification Initiative, CFI）」的大框架下，「网络韧性评估框架（Cyber Resilience Assessment Framework, C-RAF）」的推出，为银行业设立了一套极其严格且具前瞻性的安全准则。</p><p>随着 C-RAF 演进至 2.0 版本，监管的要求变得更加具体且具备技术深度。对于认可机构（AIs）而言，理解如何正确执行渗透测试与网络攻击模拟测试，是确保牌照合规与业务不中断的关键。本篇文章将深入分析 C-RAF 2.0 的各项技术与法规要求，为香港金融机构提供一份全面的执行指南。</p><p>&nbsp;</p><h2 class="green-h2">为什麽 C-RAF 2.0 是香港银行业的转捩点</h2><p>在过去的资安审计模式中，多数机构採取的是「基于合规」的被动防禦。机构只要证明自己安装了防火牆、拥有加密系统并进行了年度扫描，通常就能通过审计。然而，随着针对金融机构的勒索软件、供应链攻击以及国家级黑客行为日益猖獗，HKMA 意识到单纯的「防护」已经不够。</p><p>C-RAF 2.0 的核心哲学是「网络韧性（Cyber Resilience）」。这个概念的重点在于接受「攻击终将发生」的现实。因此，框架的要求不再只是检查你的门锁是否牢固，而是要求银行证明：当攻击者进入内部网络时，银行是否具备足够的监控能力来发现入侵？是否具备足够的反应能力来阻止损害扩大？以及是否能在最短时间内恢復核心业务功能？</p><p>&nbsp;</p><h2 class="green-h2">C-RAF 2.0 评估体系的三大支柱深度解析</h2><p>要完全符合 C-RAF 2.0 的要求，认可机构必须完成三个阶段的评估流程。渗透测试在不同的阶段扮演着不同的角色。</p><p>第一项支柱：固有风险评估 (Inherent Risk Assessment)<br>这是评估流程的起点。银行需要根据其业务活动、产品複杂性、技术环境以及外包依赖程度进行自我评核。根据评分结果，银行会被归类为「低」、「中」或「高」风险等级。风险等级越高，后续对渗透测试的频率与技术深度要求就越严格。</p><p>第二项支柱：成熟度评估 (Maturity Assessment)<br>在这个阶段，银行需要对照 C-RAF 提供的成熟度标准，评估其在识别、保护、侦测、应对及恢復这五大范畴的实际表现。这不仅仅是文件审核，还需要提供技术证据。例如，银行必须证明其侦测机制能有效识别异常流量，这通常需要透过内部的漏洞扫描与安全性测试来验证。</p><p>第三项支柱：情报主导的网络攻击模拟测试 (iCAST)<br>这是 C-RAF 2.0 最具技术含量的部分。对于风险等级为「中」或「高」的银行，iCAST 是强制性的要求。与传统渗透测试不同，iCAST 是一种基于实际威胁情报的红队演习。它要求测试者模拟真实黑客组织的战术、技术与流程（TTPs），对银行的关键基础设施发起模拟攻击。</p><p>&nbsp;</p><h2 class="green-h2">渗透测试与 iCAST 的技术差异与选择</h2><p>许多企业管理层容易混淆「传统渗透测试」与「iCAST」。理解这两者的差异，对于编列资安预算与选择服务供应商至关重要。</p><p>传统渗透测试的主要目标是「发现漏洞」。测试人员会尝试入侵特定系统，找出未修补的代码漏洞、错误的系统配置或脆弱的登录凭证。这种测试通常是针对性的，范围较窄，目标是确保系统本身是安全的。</p><p>相比之下，iCAST 是「目标导向」且「威胁导向」的。测试过程分为三个阶段。首先是「威胁情报阶段」，专业情报团队会分析目前有哪些黑客组织正在针对香港银行业，以及他们使用的攻击路径。其次是「场景开发阶段」，根据情报设计出针对该银行的特定攻击路径，例如透过伪造供应商邮件入侵内网。最后是「执行阶段」，红队人员会在不预先通知银行防守团队（蓝队）的情况下进行攻击，测试银行的实时侦测与应对能力。</p><p>&nbsp;</p><h2 class="green-h2">C-RAF 2.0 渗透测试的关键合规细节</h2><p>在准备执行 C-RAF 测试时，认可机构必须确保符合以下几项关键的合规标准，否则测试报告可能不获金管局认可。</p><p>第一点：测试人员的专业资格与独立性<br>HKMA 非常看重执行团队的专业性。认可机构应聘请具备国际认证的第三方资安公司，例如具备 CREST (Certified Registered Ethical Security Testers) 认证的团队。此外，必须严格遵守独立性原则，负责系统开发或维护的供应商，不能同时担任该系统的渗透测试方。</p><p>第二点：测试范围的全面复盖<br>合规的渗透测试不能只针对外网门户网站。根据 C-RAF 的精神，测试范围必须涵盖：核心银行系统、Swift 支付网关、网上银行与移动理财 App、内部域控伺服器 (Active Directory) 以及所有与第三方服务商对接的 API 接口。</p><p>第三点：修补机制与闭环管理<br>测试结束后拿到的报告只是过程的一半。认可机构必须根据报告中的风险排名（紧急、高、中、低）制定详细的修补计划。对于高风险漏洞，HKMA 通常要求在极短时间内修復。修復完成后，必须由第三方团队进行「複测」，确认漏洞已彻底解决，并将複测报告作为最终合规文件存档。</p><p>&nbsp;</p><h2 class="green-h2">为什麽有些银行的资安审计会失败</h2><p>根据行业经验，认可机构在面对 C-RAF 评估时，常见的失败原因包括：</p><p>第一项原因：数据资产清单不完整。银行无法准确识别哪些是「关键资讯资产」，导致渗透测试的复盖面出现盲区。</p><p>第二项原因：对第三方外包风险的低估。许多银行虽然自身防禦严密，但与外包技术供应商的对接点却存在严重的安全缺陷，黑客常以此作为跳板入侵。</p><p>第三项原因：缺乏持续的监控机制。很多机构在测试期间表现良好，但一旦测试结束，系统配置变动或新漏洞出现后，缺乏自动化的漏洞管理流程。</p><p>&nbsp;</p><h2 class="green-h2">如何准备一场成功的 C-RAF 2.0 渗透测试</h2><p>为了确保测试流程顺利进行并达到监管标准，我们建议认可机构採取以下步骤：</p><p>步骤一：进行预先评估与差距分析。在正式的 C-RAF 评估开始前六个月，聘请顾问进行一次模拟审核，找出成熟度不足的地方，并预先进行修补。</p><p>步骤二：强化威胁情报能力。对于需要进行 iCAST 的机构，应提前与具备威胁情报能力的服务商建立合作，了解行业内最新的攻击趋势。</p><p>步骤三：建立跨部门协作机制。渗透测试不仅是 IT 的事，合规部、风险管理部甚至是业务部都应参与其中，确保测试范围与实际业务运作紧密结合。</p><p>&nbsp;</p><h2 class="green-h2">将合规转化为企业信任</h2><p>在香港这个高度竞争的金融市场，客户对数字服务的安全感是品牌价值的重要组成部分。通过 HKMA C-RAF 2.0 的严格测试，虽然在短期内需要投入人力与财力，但从长远来看，这能极大地降低发生重大网络安全事故的机率。</p><p>网络安全是一个动态的过程，C-RAF 2.0 为银行业提供了一个持续进步的蓝图。当银行能够证明自己不仅能「防守」，还能在遭受打击后迅速「反击」与「恢復」时，这种韧性将成为银行最核心的竞争优势。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">强化企业安全 🛡️ 立即行动</h2><p style="text-align:center;">UD 是值得信赖的託管安全服务供应商（MSSP）<br>拥有 20+ 年经验，已为超过 50,000 家企业提供解决方案<br>涵盖渗透测试、漏洞扫描、SRAA 等全方位网络安全服务，全面保护现代企业。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">马上谘询资安专家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/sc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">为企业进行渗透测试</a></div><p>&nbsp;</p><p>&nbsp;</p>

<p>在當前全球金融環境中，網絡安全已不再僅僅是資訊科技部門的責任，而是上升到了企業管治與合規經營的核心層面。香港金融管理局（HKMA）作為香港銀行業的監管者，一直致力於維護香港國際金融中心的穩定性。在「網絡防衛計劃（Cyber Fortification Initiative, CFI）」的大框架下，「網絡韌性評估框架（Cyber Resilience Assessment Framework, C-RAF）」的推出，為銀行業設立了一套極其嚴格且具前瞻性的安全準則。</p><p>隨著 C-RAF 演進至 2.0 版本，監管的要求變得更加具體且具備技術深度。對於認可機構（AIs）而言，理解如何正確執行滲透測試與網絡攻擊模擬測試，是確保牌照合規與業務不中斷的關鍵。本篇文章將深入分析 C-RAF 2.0 的各項技術與法規要求，為香港金融機構提供一份全面的執行指南。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">為什麼 C-RAF 2.0 是香港銀行業的轉捩點</h2><p>在過去的資安審計模式中，多數機構採取的是「基於合規」的被動防禦。機構只要證明自己安裝了防火牆、擁有加密系統並進行了年度掃描，通常就能通過審計。然而，隨著針對金融機構的勒索軟件、供應鏈攻擊以及國家級黑客行為日益猖獗，HKMA 意識到單純的「防護」已經不夠。</p><p>C-RAF 2.0 的核心哲學是「網絡韌性（Cyber Resilience）」。這個概念的重點在於接受「攻擊終將發生」的現實。因此，框架的要求不再只是檢查你的門鎖是否牢固，而是要求銀行證明：當攻擊者進入內部網絡時，銀行是否具備足夠的監控能力來發現入侵？是否具備足夠的反應能力來阻止損害擴大？以及是否能在最短時間內恢復核心業務功能？</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">C-RAF 2.0 評估體系的三大支柱深度解析</h2><p>要完全符合 C-RAF 2.0 的要求，認可機構必須完成三個階段的評估流程。滲透測試在不同的階段扮演著不同的角色。</p><p>第一項支柱：固有風險評估 (Inherent Risk Assessment)<br>這是評估流程的起點。銀行需要根據其業務活動、產品複雜性、技術環境以及外包依賴程度進行自我評核。根據評分結果，銀行會被歸類為「低」、「中」或「高」風險等級。風險等級越高，後續對滲透測試的頻率與技術深度要求就越嚴格。</p><p>第二項支柱：成熟度評估 (Maturity Assessment)<br>在這個階段，銀行需要對照 C-RAF 提供的成熟度標準，評估其在識別、保護、偵測、應對及恢復這五大範疇的實際表現。這不僅僅是文件審核，還需要提供技術證據。例如，銀行必須證明其偵測機制能有效識別異常流量，這通常需要透過內部的漏洞掃描與安全性測試來驗證。</p><p>第三項支柱：情報主導的網絡攻擊模擬測試 (iCAST)<br>這是 C-RAF 2.0 最具技術含量的部分。對於風險等級為「中」或「高」的銀行，iCAST 是強制性的要求。與傳統滲透測試不同，iCAST 是一種基於實際威脅情報的紅隊演習。它要求測試者模擬真實黑客組織的戰術、技術與流程（TTPs），對銀行的關鍵基礎設施發起模擬攻擊。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">滲透測試與 iCAST 的技術差異與選擇</h2><p>許多企業管理層容易混淆「傳統滲透測試」與「iCAST」。理解這兩者的差異，對於編列資安預算與選擇服務供應商至關重要。</p><p>傳統滲透測試的主要目標是「發現漏洞」。測試人員會嘗試入侵特定系統，找出未修補的代碼漏洞、錯誤的系統配置或脆弱的登錄憑證。這種測試通常是針對性的，範圍較窄，目標是確保系統本身是安全的。</p><p>相比之下，iCAST 是「目標導向」且「威脅導向」的。測試過程分為三個階段。首先是「威脅情報階段」，專業情報團隊會分析目前有哪些黑客組織正在針對香港銀行業，以及他們使用的攻擊路徑。其次是「場景開發階段」，根據情報設計出針對該銀行的特定攻擊路徑，例如透過偽造供應商郵件入侵內網。最後是「執行階段」，紅隊人員會在不預先通知銀行防守團隊（藍隊）的情況下進行攻擊，測試銀行的實時偵測與應對能力。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">C-RAF 2.0 滲透測試的關鍵合規細節</h2><p>在準備執行 C-RAF 測試時，認可機構必須確保符合以下幾項關鍵的合規標準，否則測試報告可能不獲金管局認可。</p><p>第一點：測試人員的專業資格與獨立性<br>HKMA 非常看重執行團隊的專業性。認可機構應聘請具備國際認證的第三方資安公司，例如具備 CREST (Certified Registered Ethical Security Testers) 認證的團隊。此外，必須嚴格遵守獨立性原則，負責系統開發或維護的供應商，不能同時擔任該系統的滲透測試方。</p><p>第二點：測試範圍的全面覆蓋<br>合規的滲透測試不能只針對外網門戶網站。根據 C-RAF 的精神，測試範圍必須涵蓋：核心銀行系統、Swift 支付網關、網上銀行與移動理財 App、內部域控伺服器 (Active Directory) 以及所有與第三方服務商對接的 API 接口。</p><p>第三點：修補機制與閉環管理<br>測試結束後拿到的報告只是過程的一半。認可機構必須根據報告中的風險排名（緊急、高、中、低）制定詳細的修補計劃。對於高風險漏洞，HKMA 通常要求在極短時間內修復。修復完成後，必須由第三方團隊進行「複測」，確認漏洞已徹底解決，並將複測報告作為最終合規文件存檔。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">為什麼有些銀行的資安審計會失敗</h2><p>根據行業經驗，認可機構在面對 C-RAF 評估時，常見的失敗原因包括：</p><p>第一項原因：數據資產清單不完整。銀行無法準確識別哪些是「關鍵資訊資產」，導致滲透測試的覆蓋面出現盲區。</p><p>第二項原因：對第三方外包風險的低估。許多銀行雖然自身防禦嚴密，但與外包技術供應商的對接點卻存在嚴重的安全缺陷，黑客常以此作為跳板入侵。</p><p>第三項原因：缺乏持續的監控機制。很多機構在測試期間表現良好，但一旦測試結束，系統配置變動或新漏洞出現後，缺乏自動化的漏洞管理流程。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">如何準備一場成功的 C-RAF 2.0 滲透測試</h2><p>為了確保測試流程順利進行並達到監管標準，我們建議認可機構採取以下步驟：</p><p>步驟一：進行預先評估與差距分析。在正式的 C-RAF 評估開始前六個月，聘請顧問進行一次模擬審核，找出成熟度不足的地方，並預先進行修補。</p><p>步驟二：強化威脅情報能力。對於需要進行 iCAST 的機構，應提前與具備威脅情報能力的服務商建立合作，了解行業內最新的攻擊趨勢。</p><p>步驟三：建立跨部門協作機制。滲透測試不僅是 IT 的事，合規部、風險管理部甚至是業務部都應參與其中，確保測試範圍與實際業務運作緊密結合。</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">將合規轉化為企業信任</h2><p>在香港這個高度競爭的金融市場，客戶對數字服務的安全感是品牌價值的重要組成部分。通過 HKMA C-RAF 2.0 的嚴格測試，雖然在短期內需要投入人力與財力，但從長遠來看，這能極大地降低發生重大網絡安全事故的機率。</p><p>網絡安全是一個動態的過程，C-RAF 2.0 為銀行業提供了一個持續進步的藍圖。當銀行能夠證明自己不僅能「防守」，還能在遭受打擊後迅速「反擊」與「恢復」時，這種韌性將成為銀行最核心的競爭優勢。</p><p>&nbsp;</p><h2 class="green-h2" style="text-align:center;">強化企業安全 🛡️ 立即行動</h2><p style="text-align:center;">UD 是值得信賴的託管安全服務供應商（MSSP）<br>擁有 20+ 年經驗，已為超過 50,000 家企業提供解決方案<br>涵蓋滲透測試、漏洞掃描、SRAA 等全方位網絡安全服務，全面保護現代企業。</p><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal" data-cta="Service-Enquiry" href="https://www.udomain.hk/tc/managed-security-service-provider-mssp-hong-kong?utmsource=Content%20Hub">馬上諮詢資安專家</a></div><div class="raw-html-embed"><a id="productEnquiryBtn" class="normal green" data-cta="Service-Enquiry" href="https://www.udomain.hk/tc/service/network-cybersecurity-penetration-test?utmsource=Content%20Hub">為企業進行滲透測試</a></div><p>&nbsp;</p><p>&nbsp;</p>

[HK Banking] HKMA C-RAF 2.0 Penetration Testing Guide: Compliance Details for Authorized Institutions

[香港银行业] HKMA C-RAF 2.0 渗透测试指南：认可机构必须知道的合规细节

[香港銀行業] HKMA C-RAF 2.0 滲透測試指南：認可機構必須知道的合規細節

<p>Since their inception, virtual banks in Hong Kong have completely transformed how citizens manage their finances. As authorized institutions that rely entirely on digital channels to provide services, virtual banks face security standards that are even more stringent than those of traditional banks. Under the HKMA's Cyber Fortification Initiative (CFI), the iCAST framework is considered the highest level of examination for a bank's cyber resilience.</p><p>Unlike traditional penetration tests, iCAST is not just about finding system vulnerabilities. It is a pre-planned, intelligence-driven red teaming exercise. For virtual banks, which are heavily dependent on cloud architecture and API integration, the challenges of iCAST are significant. This article provides a detailed preparation checklist for decision-makers and technical teams at virtual banks to ensure they navigate this rigorous test successfully.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Understanding the Unique Significance of iCAST for Virtual Banks</h2><p>The primary difference between a virtual bank and a traditional one is its "branchless" nature. This means that all business logic, customer verification, and fund transfers occur in the cloud and on mobile applications. In the context of iCAST, attackers will not try to break into an office building. Instead, they will target cloud misconfigurations, mobile app vulnerabilities, or third-party supply chain weaknesses.</p><p>The core of iCAST is "realism." It simulates how highly organized hacker groups would actually conduct reconnaissance and attempt to infiltrate your bank. For a virtual bank, this is a prime opportunity to verify if its digital fortress can withstand professional hackers and a key indicator to prove operational resilience to the HKMA.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Phase One: Asset and Risk Definition</h2><p>Before the formal testing begins, the virtual bank must complete an internal asset inventory.</p><p>Step One: Define Critical Business Functions<br>Virtual banks need to identify which services are absolutely critical and cannot be interrupted. This typically includes the onboarding process (eKYC), instant transfers (FPS), fixed deposits, and loan approval systems. The iCAST scenarios will revolve around these functions, so the bank must clarify the technical dependencies of these paths.</p><p>Step Two: Map the Technical Ecosystem<br>Since virtual banks make extensive use of microservices and containerization (Docker/Kubernetes), the technical team must prepare a map covering all internal and external connection points. This includes cloud service providers (AWS, Azure, GCP), identity verification services, and third-party e-wallet interfaces.</p><p>Step Three: Establish Exclusion Zones and Safety Constraints<br>While iCAST pursues realism, the bank must agree on the "Rules of Engagement" with the testers. For instance, is testing permitted in the production environment? What is the emergency stop mechanism if the test causes system instability? Ensuring 24/7 service availability is the bottom line for virtual banks, so clear "circuit breaker" mechanisms must be set.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Phase Two: Threat Intelligence and Scenario Development</h2><p>The soul of iCAST lies in its "intelligence-led" approach.</p><p>Step One: Gather Target-Specific Threat Intelligence<br>Banks should collaborate with security vendors capable of threat intelligence to analyze which hacker groups (such as APT actors) are currently targeting fintech or virtual banks. This intelligence should include samples of phishing emails, malware variants, and penetration paths commonly used by these actors.</p><p>Step Two: Design Customized Attack Scenarios<br>Based on the gathered intelligence, the bank needs to develop at least three attack scenarios. For virtual banks, common scenarios include exploiting mobile app code vulnerabilities to bypass authentication, attacking cloud management consoles to gain administrative privileges, or compromising a developer's DevOps pipeline to plant backdoors.</p><p>Step Three: Review Scenarios for Regulatory Compliance<br>All testing scenarios must be submitted to the HKMA or relevant regulatory bodies for the record. This ensures that the test fulfills its purpose of examination while adhering to regulatory requirements regarding bank stability.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Phase Three: Technical Defense Hardening</h2><p>Before the Red Team (testers) launches the attack, the Blue Team (the bank’s internal defense team) should perform a self-check.</p><p>Step One: Strengthen Cloud Configuration Security<br>Virtual banks should review permissions for all cloud storage (S3 Buckets), security group rules, and Identity and Access Management (IAM) policies. Cloud misconfiguration is the most common vulnerability exploited by hackers in digital-first organizations.</p><p>Step Two: Audit Mobile App Code and API Security<br>Conduct stress tests and vulnerability scans on all external APIs to ensure they are resistant to injection attacks and cross-site scripting (XSS). Simultaneously, apply code obfuscation and anti-debugging checks to mobile apps to make reverse engineering more difficult for hackers.</p><p>Step Three: Test Logging, Monitoring, and Alerting Systems<br>A virtual bank must ensure its Security Operations Center (SOC) can receive real-time alerts for anomalies. For example, if multiple failed login attempts are detected from an unusual geographic location, does the system automatically trigger an alert? A major focus of iCAST is checking whether your Blue Team can detect Red Team movements in time.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Phase Four: Organizational Coordination and Communication</h2><p>iCAST is not just a technical test; it is a test of management processes.</p><p>Step One: Form a Crisis Communication Task Force<br>Establish an emergency group consisting of the Chief Information Security Officer (CISO), legal counsel, and public relations teams. During the test, if an unexpected data leak or system outage occurs, this group must be able to take control and decide whether to release a statement or report to the HKMA.</p><p>Step Two: Define Internal Confidentiality Protocols<br>To ensure the realism of the test, only a few senior executives (the White Team) should be aware of the exact timing and paths of the attack. Most IT operations staff and customer service personnel should remain unaware to test their genuine reactions to a sudden security incident.</p><p>Step Three: Prepare Remediation and Recovery Plans<br>The test report will inevitably list vulnerabilities. Virtual banks must reserve enough technical resources (developers and system architects) to patch high-risk vulnerabilities immediately after the test and complete the retest within the required timeframe.</p><h2 style="margin-left:0px;">&nbsp;</h2><h2 class="green-h2" style="margin-left:0px;">Turning iCAST into a Badge of Trust</h2><p>For a virtual bank, passing an iCAST assessment is more than just meeting a regulatory requirement.
