Free Whitepaper
"Are You Prepared for Data Terrorism?"
As long as critical data is online, it is available to a data 
terrorist. If
a data terrorist succeeds in getting access, this white paper reveals 
how to
contain the damage by employing data protection strategies that 
de-couple
the data from the terrorist.

NOTE FROM THE EDITOR:

This February issue focuses on Network Security -- always an essential 
topic to systems administrators. In this issue, Barnett and Smith 
provide an overview of IPCop, an inexpensive solution for intranets 
that require comprehensive network security. Rajeev Kumar explains 
how to set up Squid as a proxy firewall in front of your Web server. 
And, Lawrence Teo describes Dovecot, an open source IMAP server that 
advertises itself as "an IMAP and POP3 server for Linux/Unix-like 
systems, written primarily with security in mind." I hope you find 
these 
articles useful. As always, feel free to contact me with article 
ideas and suggestions for future coverage.

Sincerely,
Amber Ankerholz
Editor in Chief
