LINUX: Linux uses the variable tcp_max_syn_backlog to define the maximum half number of connections that the backlog queue can hold. In Redhat 7.3, the value of this variable defaults to 256, which is far from enough. A low-intensity SYN attack can fill up the half-connection queue. We can modify the value of this variable with the following command:

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.
