Land Attacks

A land attack is similar to a SYN attack, the only difference  being that instead of including an invalid IP address, the SYN packets include the IP address of the target system itself. More specifically, the source IP address and port number are identical to the destination IP address and port number. As a result, an infinite loop is created within the target system, which ultimately hangs and crashes.

Countermeasure :- The easiest way to protect your system against land attacks is to install a firewall or filtering utility that filters out outgoing packets whose destination IP address is the same as the IP address of the local system.
