Since http is based on tcp, You need to complete a three-way handshake to establish a tcp connection before you can start http communication, Therefore, when http flood attacks are carried out, it is not possible to use forged source ip addresses to launch attacks. An attacker will typically use an http proxy server, Not only can the source be hidden from being traced, It also improves attack efficiency-after the attacker connects to the proxy server and sends the request, You can directly disconnect from the proxy server and start connecting to the next proxy server, At this time, the http connection between the proxy server and the target web server is still maintained, and the web server needs to continue to accept and process data. An efficient http flood attack should continuously send http requests for different resources and pages, and request resources that cannot be cached as much as possible (such as keyword search.

Use Your Customers to Find CustomersIf an attack is detected, the management center will start a cleaning scheme to pull the mixed traffic of attack traffic and normal traffic through BGP, CDN, etc. Pull the mixed flow to the flow cleaning center for cleaning. The problem in the process of traffic cleaning is that the current DDOS attacks present a mixed attack state with multiple attack methods coexisting. In this case, how to efficiently detect attacks is the main problem currently facing. After consulting numerous data, Huawei's "seven-layer cleaning plan" is found to be very enlightening. The scheme comprehensively analyzes data packets for mixed traffic through seven layers of defense measures such as static filtering, abnormal message filtering, scanning and snooping message filtering, source legitimacy authentication, session-based prevention, feature identification filtering and traffic shaping, so as to detect attack traffic to the greatest extent. The framework of Huawei's "seven-layer cleaning scheme" is shown in Figure 2. After the traffic is cleaned, the attack traffic is discarded, and the normal traffic is injected back into the network through MPLS, GRE tunnel technology, etc.
