Information
If the domain is not configured to restrict privileged administrator accounts from logging on to lower-tier hosts, it would be impossible to isolate administrative accounts to specific trust zones and protect IT resources from threats from high-risk trust zones. Blocking logon to lower-tier assets helps protect IT resources in a tier from being attacked from a lower tier.
Solution
Configure domain systems to prevent higher-tier administrative accounts from logging on to lower-tier hosts.
Assign higher-tier administrative groups to the Deny log on user rights of lower-tier hosts. This includes the following user rights:
Deny log on as a batch job
Deny log on as a service
Deny log on locally
Domain and Enterprise Admins are currently required to be included in the appropriate deny user rights in the Windows STIGs for member servers and workstations.
