Hardening is the process of protecting a system against unknown threats. Hardening Windows Second Edition is the definitive "counterintelligence" guide to performing preventative security measures for Windows-based networks.
The second edition covers the release of Windows XP Service Pack 2 and its new security features, including the Windows Firewall and the Security Center. It also covers Windows Server 2003 Service Pack 1, Windows Server R2's new Security Configuration Wizard, Windows NT, Windows 2000, branch-office security features, and new setup options. Over one-third of the material in the first edition has been rewritten and expanded to the tune of an additional 125 pages.
