Assessment Title

Rule Text

Local administrator accounts must have their privileged token filtered to prevent elevated privileges from being used over the network on domain systems.

Description

Discussion Text

A compromised local administrator account can provide means for an attacker to move laterally between domain systems. With User Account Control enabled, filtering the privileged token for local administrator accounts will prevent the elevated privileges of these accounts from being used over the network.

How this relates to the STIG checklist: STIG vs SCAP benchmark.
