System administrators know the Internet is a hostile environment. They can't tell when a hacker will attempt to gain access to the SQL server, but they can bet that there will be an attempt soon. Because the operating system is vital to a computer's functioning, and because it's the only layer between the machine's available resources and its users, it's critical that the operating system resist compromise. Hardening Windows is an intermediate-to-advanced guide to implementing preventative security measures for the Windows operating system, and it's the only book that covers NT, 2000, XP, and 2003. This book is designed to provide a quick and easy checklist-style reference to the steps system administrators need to take to anticipate attacks and compromises, and to harden Windows NT, 2000, XP, and Server 2003 against them.
