Security: Prevents ARP Poisoning

You can prevent Man In The Middle attacks based on ARP poisoning using the following techniques:

Static entries on ARP table: this solution could be used only for small network.

ArpAssure: is a small utility that has been designed to assure the correct IP to MAC mapping on a remote network node.

ArpWatch: is a tool that monitors ethernet activity and keeps a database of ethernet/ip address pairings; it works on Linux/Unix and maybe on Windows with cygwin.

If you don't know what ARP poisoning is and why it is dangerous, then google it !
