About the Authors
Tony Northrup, MCSE and CISSP, is a consultant and author living in the Boston, Mas
sachusetts, area. During his seven years as Principal Systems Architect at BBN/Genuity,

Needless to say, Tony learned the hard way how to keep Windows systems safe in a
hostile environment. Tony has authored and co-authored many books on Windows

Resource Kit Performance and Troubleshooting Guide. Tony has also written several
papers for Microsoft TechNet, covering firewalls, ASP.NET, and other security topics.
