What should you monitor to ensure that old or unused user access entries are deleted in an operating system?

Monitoring access control is crucial for maintaining the security and integrity of an operating system. Access control encompasses the policies and mechanisms that manage the permissions and access rights of users to resources within the system. By regularly reviewing and managing access control entries, organizations can identify and remove old or unused user access. This practice helps mitigate the risk of unauthorized access due to accounts that are no longer active or needed.

Managing access control involves looking for user accounts that haven’t been used in some time, accounts associated with former employees, or accounts that were temporarily created for specific projects. When these entries are monitored and outdated ones are deleted, it reduces potential vulnerabilities that could be exploited by malicious users.

In the context of operating systems, effective access control is a fundamental aspect of maintaining security and ensuring that only appropriate users have access to sensitive information and system functions.
