Assessment Title

Rule Text

The Lock pages in memory user right must not be assigned to any groups or accounts.

Description

Discussion Text

Inappropriate granting of user rights can provide system, administrative, and other high level capabilities. The "Lock pages in memory" user right allows physical memory to be assigned to processes, which could cause performance issues or a DoS.
