Description
An account that does not have Administrator duties must not have Administrator rights. Such rights would allow the account to bypass or modify required security restrictions on that machine and make it vulnerable to attack. System administrators must log on to systems only using accounts with the minimum level of authority necessary. For domain-joined workstations, the Domain Admins group must be replaced by a domain workstation administrator group. Restricting highly privileged accounts from the local Administrators group helps mitigate the risk of privilege escalation resulting from credential theft attacks. Systems dedicated to the management of Active Directory (AD admin platforms, see V-36436 in the Active Directory Domain STIG) are exempt from this. Standard user accounts must not be members of the built-in Administrators group.

Review the local Administrators group. Only the appropriate administrator groups or accounts responsible for administration of the system may be members of the group. For domain-joined workstations, the Domain Admins group must be replaced by a domain workstation administrator group. Systems dedicated to the management of Active Directory (AD admin platforms, see V-36436 in the Active Directory Domain STIG) are exempt from this. Standard user accounts must not be members of the local administrator group. If prohibited accounts are members of the local administrators group, this is a finding. The built-in Administrator account or other required administrative accounts would not be a finding.
