Inverse firewalling, making sure direct connections to the Internet is not 
allowed.

To use proxy authenticaiton you must be using a client configured to use 
the proxy.

Proxy authentication gives much stronger audit trails than any firewall
logs, as the proxy logs will contain detailed information about who in
person went where when, not just a mix of ipaddresses and ports.

Btw, the logging capabilities of iptables truly sucks in comparisation 
with a Squid proxy. Basically non-existant.
