Compared with other CDN service providers, the main advantages of CDN include stable and fast, cost-effective, easy to use, efficient and intelligent. More users will ask about the advantage of stability and speed. Generally speaking, CDN is characterized by sharing the pressure on the origin server, avoiding network congestion, accelerating the distribution of website content in different regions and different scenarios, and improving the speed of resource access. The following is to introduce what you should pay attention to in the security service of CDN business.

What should be paid attention to in the security service of cdn business? Many enterprises realize that ddos defense is critical to the customer experience, and CDN, which provides highly available and high-performance content to users, is also vulnerable to all kinds of attacks. Therefore, the security service of cdn business must guard against these threats.

Dynamic content attack

Attackers have learned that the major blind spot in CDN services is the handling of requests for dynamic content. Because dynamic content is not stored in the CDN server, all dynamic content requests are sent to the source server. Attackers can take advantage of this behavior to generate attack traffic that contains random parameters of HTTP GET requests.

SSL-based attack

The target of SSL-based DDoS attack is secure online service. These attacks are easy to launch, but difficult to mitigate, so they become the favorite of attackers. In order to detect and mitigate DDoS SSL attacks, the CDN server must first decrypt traffic using the customer's SSL key.

Direct IP attack

Once an attacker launches a direct attack on the IP address of a customer's source Web server, even applications serviced by CDN will be attacked. These attacks may be UDP floods or ICMP floods, and network floods that are not transmitted through CDN services will directly hit the customer source server.

Web application attack

CDN protection against Web application threats has a limited level of protection, exposing customer Web applications to data leaks, data theft, and other common Web application threats. Most CDN-based Web application firewalls also have limited functionality and are only applicable to a basic set of predefined signatures and rules.

Therefore, CDN security services need to be sensitive enough to deal with various network attacks. The above is the arrangement of security service attention aspects of cdn business.
