Assessment Title

Rule Text

The Create symbolic links user right must only be assigned to the Administrators group.

Description

Discussion Text

Inappropriate granting of user rights can provide system, administrative, and other high level capabilities. Accounts with the "Create symbolic links" user right can create pointers to other objects, which could potentially expose the system to attack.

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