Guessing or knowing the initial TCP sequence number (ISN) that a server will choose enables an attacker to establish a TCP connection.

1. Server selects ISN as ISN = [H(source IP address || destination IP address || source port number || destination port number || currenttime
2. Server selects ISN at random.
