SYN flooding (or TCP SYN flood) is a form of denial-of-service attack against systems that provide services over the Transmission Control Protocol (TCP). It exploits the way many TCP implementations handle incoming connection requests by causing a server to retain state for large numbers of incomplete (or “half-open”) connections, leaving insufficient resources to accept new legitimate connections.
