Information
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 member servers, the Domain Admins group must be replaced by a domain member server administrator group (see V-36433 in the Active Directory Domain STIG). Restricting highly privileged accounts from the local Administrators group helps mitigate the risk of privilege escalation resulting from credential theft attacks.
Standard user accounts must not be members of the built-in Administrators group.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
Configure the system to include only administrator groups or accounts that are responsible for the system in the local Administrators group.
For domain-joined member servers, replace the Domain Admins group with a domain member server administrator group.
Remove any standard user accounts.
