Assessment Title

Rule Text

Print driver installation privilege must be restricted to administrators.

Description

Discussion Text

The print spooler allows users to add and to delete printer drivers on the local system. This capability must be restricted to privileged groups to ensure only stable, non-malicious drivers are used.

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