The answer given in front of you is the basic conditions for the interview, which cannot represent the requirements of a class of physical examination. The specific and detailed indexes of each item can be found on the official website of CAAC.SYN flooding attacks can attack with fewer packets than ordinary brute-force DoS attacks that only send a large number of packets to the target network. However, this requires some understanding of the server's operating system, such as how much backlog queue space it allocates and how long it will keep the TCB in the SYN-RECIEVED state before timeout and discarding the TCB. For example, an attacker can send a certain number of SYN packets that are exactly the size of the backlog queue, and their cycles are just the time when the TCB is recycled, thus making the server permanently unavailable.Is it TCP to try to send enough SYN packets and run out of backlog? The purpose of SYN flooding. The attacker added the source IP address to the SYN packet, which would not cause the host to remove the assigned TCB from the SYN-RECEVIED state queue (because the host would respond to the SYN-ACK). Because TCP is reliable, the destination host will wait quite a long time before disconnecting the half-open connection and removing the TCB from the SYN-RECIEVED queue. During this period, the server will not be able to respond to legitimate new TCP connection requests from other applications. Figure 2 shows a simple TCP? The process of a SYN flooding attack.
