The Windows XP Security Guide which provides recommendations for deploying Windows XP in three distinct environments was updated last week to reflect the availability of XP SP2. It has 7 chapters and an appendix which provides additional guidance for Windows XP Service Pack 2. An overview is at http://www.microsoft.com/technet/security/prodtech/winclnt/secwinxp/default.mspx and the complete guide can be downloaded from that page.
