We propose a more robust scheme to detect SYN flooding attacks. Existing methods for detecting SYN flooding are based on the protocol behavior of TCP SYN-FIN (RST) or SYN-ACK pairs, as normally the number of SYN packets is equal to that of FIN (added with RST) packets, or ACK packets in the handshake. When SYN flood starts, there will be more SYN packets. However, the attacker can avoid the detection by sending the FIN or RST packets (ACK packets) in conjunction with the SYN packets.
