'Hardening Windows' is an intermediate to advanced guide to implementing preventative security measures for the Windows operating system, and the only book that covers NT, 2000, XP, and 2003.
Hardening is this process of protecting a system against unknown threats. System administrators harden against that which they think could be a threat. This book is designed to provide a quick and easy checklist-style reference to the steps system administrators need to take to anticipate those attacks and compromises and to harden Windows NT, 2000, XP, and Server 2003 against them.
