Assessment Title

Rule Text

The Create global objects user right must only be assigned to Administrators, Service, Local Service, and Network Service.

Description

Discussion Text

Inappropriate granting of user rights can provide system, administrative, and other high level capabilities. Accounts with the "Create global objects" user right can create objects that are available to all sessions, which could affect processes in other users' sessions.

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