The Administrator Accounts Security Planning Guide
This guide is designed to be an indispensable resource when organizations plan their strategy to secure administrator-level accounts in Microsoft Windows NT–based operating systems such as Windows Server 2003 and Windows XP. It addresses the problem of intruders who acquire administrator account credentials and then use them to compromise the network. The main goal of this guide is to provide prescriptive guidance in terms of the steps an organization can take to secure local and domain-based administrator-level accounts and groups.
 
The Secure Access Using Smart Cards Planning Guide

The Security Monitoring and Attack Detection Planning Guide

The Services and Service Accounts Security Planning Guide
This guide is designed to be an important resource when organizations plan their strategy to run services more securely under the Microsoft® Windows Server 2003™ and Windows® XP operating systems. The guide addresses the common problem of Windows services that are set to run with the highest possible privileges, which an attacker could compromise to gain full and unrestricted access to the computer, domain, or even to the entire forest. It describes ways to identify services that can run with lesser privileges and explains how to downgrade those privileges methodically. This guide can help organizations assess their existing services infrastructure and make some important planning decisions in relation to future service deployments.
