SYN attack

Alternatively called a SYN flood, a SYN attack is a Denial of Service (DOS) attack on a computer or network. It is carried out by flooding the network with spoofed SYN packets or packets that contain an address that never responds to the SYN/ACK requests. Essentially, the connection queues fill up with bad connections, and service is denied to legitimate users.
