Because some denial of service attacks take advantage of the vulnerabilities of network protocols, others seize the limited processing capacity of the network or equipment, the prevention and treatment of denial of service attacks has become a headache for administrators. In particular, firewalls, load balancing and other equipment, which are widely used on the backbone lines in most network environments, often become the bottleneck of the whole network when DDoS attacks occur, causing the paralysis of the whole network.
Suppose the attacker is in an "interconnected" network (e.g. An Autonomous system? System), whose ISP restricts the input and output filtering of the attacker's network traffic, will be able to prevent this spoofing attack-if this method can be deployed to the correct location by the organization. This defense method of traffic input and output filtering will restrict some legitimate communications, such as the mobile IP triangular routing operation mode, so it cannot be widely deployed. IP Security Protocol (IPsec) also provides an excellent way to resist spoofing packets, but this protocol cannot be used due to deployment restrictions. Since it is usually impossible for the server side to require the ISP of the link initiator to implement address filtering or require it to use IP security protocols, more complex solutions are needed to resist this spoofing attack disguised as multiple addresses, which will be discussed later.
