The SYN Attack, for all its simplicity remains an effective means of attack, on an unprotected server. The SYN packet is the first step in establishing a connection between two computers over the internet. This event is expected and treated by servers as a normal event. However, SYN events build connections quickly; while, the server waits for each connection to proceed through its normal connection cycle. However, the attacker, in this case, has no intension of completing this cycle. The server is then left waiting for its expected ACK packet; of which, none will arrive. In this time server, resources are being accumulated to an extent in which the server is quickly overwhelmed.
