What is the main purpose of access reviews in IT security and compliance?

The correct answer is:

They confirm the right people have the right access and remove outdated permissions

Explanation:
Access reviews are crucial for maintaining security and compliance within an organization. Their primary purpose is to periodically verify that individuals have the appropriate level of access to systems and data based on their current roles and responsibilities. This process helps to:

• Ensure the principle of least privilege is enforced, meaning users only have the access they need to perform their job functions.
• Identify and revoke outdated permissions that are no longer necessary, reducing potential security risks from former employees or those who have changed roles.
• Prevent unauthorized access and data breaches by regularly validating access rights.
