Which type of review helps ensure users have appropriate access?

The type of review that helps ensure users have appropriate access is the access review. Access reviews are critical components of an identity governance process, as they involve systematically evaluating user access rights to determine if they align with the current job responsibilities and the organization's access policies.

During an access review, administrators or reviewers assess the permissions and roles granted to users, confirming whether the access they possess is necessary and appropriate for their roles. This process helps prevent excessive access and minimizes security risks. Moreover, it enables organizations to comply with regulatory requirements that mandate regular assessments of user access and entitlements.

The other types of reviews listed do not focus primarily on validating user access. Audit reviews generally assess compliance and the organization's adherence to regulations or internal controls but do not specifically evaluate access permissions. Policy reviews analyze existing policies for their relevance and effectiveness but do not directly assess user access. Performance reviews evaluate employee performance and achievements but are not concerned with access rights. Therefore, the focus on verifying and ensuring appropriate access to systems and data uniquely characterizes access reviews.
