A brief look at security monitoring recommendations for many audit events
Registry (Global Object Access Auditing) allows IT administrators to configure a global system access control list (SACL) on the registry of a computer.
On selecting select the Configure security check box on this policy’s property page, you can add a user or group to the global SACL. This configuration enables you to define computer SACLs per object type for the registry. The defined SACL is then automatically applied to every registry object type.
This policy setting must be used along with the Registry security policy setting under Object Access.
