Vandalism occurring in cyberspace and resulting in Denial of Service (DoS) to authorized users of a Website or a computer system. In SYN flooding, an attacker initiates a connection to a legitimate service accessible from the Internet (such as by email or a Web server). The setup of a TCP connection requires a three-way handshake, consisting of the following three steps: (1) the partner requesting a connection sends a SYN packet; (2) this packet is answered by a SYN-ACK packet by the receiver; (3) on reception of the SYN-ACK the initiating partner sends an ACK packet, thus completing the setup. In a SYN-flood attack, a high number of connections are initiated, but the last step is never completed by the system attacker. This incomplete setup results in a high number of half-open connections on the exploited system that eventually consume all the system’s resources, thus preventing further legitimate connections from completing their course.
