If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.

The following procedure is to use the state mode to improve the light. When it comes to encapsulation, the behavior of the encapsulated object is generally preferred over the state of the object. But the opposite is true in state mode, The key to the state mode is to encapsulate each state of the thing into a separate class, and the behaviors related to this state are encapsulated inside this class, so when button is pressed, only the request needs to be delegated to the current state object in the context, and the state object will be responsible for rendering its own behaviors. At the same time, the state switching rules can be distributed in the state classes in advance, thus effectively eliminating a large number of conditional branch statements that originally existed.

According to Threat Post, the solution is: "Open DNS resolver project organizations and other organizations (such as DNS service provider Afilias) recommend implementing source address authentication mechanisms. The existing IETF RFC and BCP-38 (see for details) specifically specify how to use the source address authentication mechanism and how to establish this architecture to defeat IP source address spoofing.
