The SYN flood attack sends TCP connections requests faster than a machine can process them.
Attacker creates a random source address for each packet SYN flag set in each packet is a request to open a new connection to the server from the spoofed IP address
Victim responds to spoofed IP address, then waits for confirmation that never arrives (timeout wait is about 3 minutes)
Victim’s connection table fills up waiting for replies and ignores new connections Legitimate users are ignored and will not be able to access the server
