... A SYN flood is a form of denial-of-service attack in which an attacker sends a succession of SYN requests to a target's system. A malicious client can skip sending this last ACK message. Or by spoofing the source IP address in the SYN, it makes the server send the SYN-ACK to the falsified IP address ...
