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.

For example, if we want to implement a JS function, Such as form validation, Then if we don't use the policy pattern in javascript described in the previous chapter to solve the form validation encapsulation code, It is a temporary form validation function written by itself. Certainly without any encapsulation, Then at this time, we will pop up a prompt to the user for whether the two values are equal. If there is a form verification on another page, their judgment method and business logic are basically the same, but the comparison parameters are different. Should we consider writing a form verification code again? So now we can consider using the template method pattern to solve this problem. Common methods are extracted, and different methods are implemented by specific subclasses. This design code also has the advantages of stronger scalability and better code ~
