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.Physical Conditions for Civil Aviation Pilots to Recruit:
