Syn Scanning

SYN scanning is a type of stealth scan that makes use of SYN packets. SYN scanning is a tactic that a malicious hacker (or cracker) can use to determine the state of a communications port without establishing a full connection. This approach, one of the oldest in the repertoire of crackers, is sometimes used to perform denial-of-service (DOS) attacks. SYN scanning is also known as half-open scanning.
