Why is performing a user access review important?

Performing a user access review is crucial because it ensures that employees have only the necessary access to systems and data required to perform their job functions. This principle of least privilege minimizes the risk of unauthorized access to sensitive information and reduces the potential attack surface for malicious actors. By regularly reviewing access levels, organizations can identify and revoke any excessive permissions that may have been granted over time, thereby enhancing the overall security posture.

Additionally, such reviews help in identifying any inactive accounts or users who no longer require access due to role changes or departures, further reinforcing security measures. This practice is essential for compliance with regulatory standards that mandate proper access control and management, ensuring that organizations adhere to best practices in cybersecurity.
