Description:
All 3 of the Security Alterations rules (Security Alterations Detected: User Privileges Granted, Security Alterations Detected: User Privileges Revoked, Security Alterations Have Been Detected) have 'null' for the Recommended Action instead of "None specified.". As a result, when any of these are scheduled you get the following error in the Miscellaneous Log:
-------------- String literal 'null' --------------
