Why Should I use Kerberos?
Since Kerberos negotiates authenticated, and optionally encrypted,
communications between two points anywhere on the Internet, it provides
a layer of security that is not dependent on which side of a firewall
either client is on. Since studies have shown that half of the computer
security breaches in industry happen from inside firewalls,
Kerberos V5 from MIT will play a vital role in the
security of your network.
