Description
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.

Verify domain systems are configured to prevent higher-tier administrative accounts from logging on to lower-tier hosts.

This can be accomplished by adding the higher-tier administrative groups to the Deny log on user rights of the lower-tier system. These include the following user rights:

Deny log on as a batch job
Deny log on as a service
Deny log on locally

If domain systems are not configured to prevent higher-tier administrative accounts from logging on to lower-tier hosts, this is a finding.

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.

Note: Severity category exception - Upgrade to a CAT I finding if any Tier 0 administrative account used to manage high-value IT resources is able to log on to a lower-tier host.
