Which of the following is used by Microsoft for auditing in order to identify past actions performed by users on an object?answerDACLPermissionsSACLUser rights

To answer the question regarding which option is used by Microsoft for auditing to identify past actions performed by users on an object, we need to understand the terms given:

1. DACL (Discretionary Access Control List): This defines the permissions for users and groups on a particular object, but it does not track past actions.

2. Permissions: These are the allowed or denied actions a user can perform on an object, but again, they do not indicate auditing or tracking of past actions.

3. SACL (System Access Control List): This is specifically designed for auditing. It can be configured to log access attempts (successful or failed) made by users on an object, making it suitable for tracking historical actions.

4. User rights: These define what a user can do in a system in terms of actions like logging in or accessing certain system resources. They are not focused on auditing past actions.

Based on the definitions, the correct choice is SACL, as it is explicitly used for auditing purposes to identify and log past actions performed by users on objects in a Windows environment.
