Man-in-the-Middle Attack

Man-In-The-Middle Attack

As discussed earlier, IPSec does not provide protection for protocols other than IP, leaving other protocols unprotected and vulnerable to attacks. One such attack uses the Address Resolution Protocol (ARP) to fool a client into sending data to a malicious peer. An attacker could launch a man-in-the-middle (MITM) attack by using forged ARP messages to insert a rogue entity into the data path.
