This policy setting allows you to audit attempts to access registry objects. A security audit event is generated only for objects that have system access control lists (SACLs) specified, and only if the type of access requested, such as Read, Write, or Modify, and the account making the request match the settings in the SACL.
If you configure this policy setting, an audit event is generated each time an account accesses a registry object with a matching SACL. Success audits record successful attempts and Failure audits record unsuccessful attempts.
If you do not configure this policy setting, no audit event is generated when an account accesses a registry object with a matching SACL.
Note: You can set a SACL on a registry object using the Permissions dialog box.
Volume: Depends on how registry SACLs are configured.
