List of Port Scanning Methods:
Does not set any bits (TCP flag header is 0).
Sets just the TCP FIN bit.
Sets the FIN, PSH, and URG flags, lighting the packet up like a Christmas tree.
This scan is different than the others discussed so far in that it never determines open (or even open|filtered) ports.
