Berkley does a pretty good job of explaining Authentication. 

http://www.net.berkeley.edu/kerberos/documents/CalAuthDef.html

Authentication refers to the process by which one party determines the
identity of another.  On an insecure computer network, where all traffic is
potentially readable (and subject to tampering) by hostile parties,
cleartext passwords no longer can be relied on to provide assurance of
identity.  Consequently, protocols and software systems have been developed
that allow people and processes to prove who they are even in the presence
of network eavesdroppers and attackers. 

And yes the Internet Storm Center notes that currently it is one of the most
attacked ports.
