An experienced administrator could use this to make sure nothing has been forgotten, and a new administrator would do well to use this as a roadmap.

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.
