Unauthorized accounts must not have the Lock pages in memory user right.

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.
