RULE ID: SV-281155r1197236
The actions taken by system administrators must be audited to keep a record of what was executed on the system, as well as for accountability purposes. Editing the "sudoers" file may be a sign of an attacker trying to establish persistent methods to a system. Auditing the editing of the "sudoers" files mitigates this risk.
