The Administrator Accounts Security Planning Guide

Chapter 4 - Summary

Updated: June 30, 2005

Because of their inherent permissions and power, the administrative accounts on computers are both the most useful and the most dangerous accounts that exist on them.

Organizations must be especially vigilant when they secure domain-level administrator accounts because an intruder who is able to compromise a domain administrator’s account can gain extensive access to every computer in your domains and forests. Microsoft has established steps to secure domain administrator accounts on its corporate network and urges other organizations to do the same.  

You should use the best practices that this guide describes as you manage your network and adhere to its principles to reduce the risk of unauthorized users who can gain administrative access to your sensitive network assets and Active Directory® directory service data.

Making administrator accounts as secure as possible is an important initiative for organizations that want to secure their network assets.

Next Steps

If an organization has not yet deployed a program for the security of administrator accounts, this planning guide provides a foundation for them to plan such a program.

The main steps that organizations should take when they plan to secure administrator accounts are:

Define a process to reduce the risk of administrator account compromise.

Identify strategies to increase the security of administrative accounts in Active Directory.

Use the principle of least privilege.

Separate domain administrator and enterprise administrator roles.

Use the Secondary Logon service to separate user and administrator accounts.

Follow best practice guidelines to secure administrator accounts.

The integrity of a program to secure administrator-level accounts is dependent on its long-term maintenance. For more information about operational best practices, see the Microsoft® Operations Framework (MOF) Web site at www.microsoft.com/technet/itsolutions/cits/mo/mof/default.mspx.
