CDN and Security Case Study: One-stop Solution For Website To Tackle Fake Wall Attack And Accelerate Content Delivery

Anti-wall CDN to maintain a secure, speedy, stable website

Hong Kong Water Taxi Cloud Managed Service

With the rising demand of online entertainment resources, there is a boom of online multimedia platforms which deliver films, TV shows, documentaries and more for audience. Content and resources delivery speed and website stability are major challenges these platforms faced.

Meanwhile, high traffic websites in particular become targets for the latest “fake wall attack”. They may suffer from instability of website, financial loss or even risk of shutting down the site. An entertainment website, which targeted users from the Mainland China, sought network support from UD, with a special request that they needed a solution to prevent fake wall attack.

Client Background




  • With the rising popularity, the website sees rapid increase of users; and considering most of the content on the website is in video format, it is necessary to strengthen the network to cope with the large volume of traffic and support streaming of content.
  • The website is in face of “fake wall attack” which is one of the latest cyberattacks discovered in the Mainland China. Simply put, hackers attempt to trigger the temporary blocking policy of The Great Firewall (GFW) to attack websites.

    First, hackers set up servers for camouflage websites overseas, then modify the IP address on the mainland server, then point the normal website to the camouflage website, and constantly send forbidden keywords to those websites. As a result, the IP address of the normal website will be blocked by The Great Firewall. It leads to the sharp decline of traffic, or even forced closure of the website as users can no longer visit the website.
