What are Access Reviews?
Azure AD Access Reviews allows you to systematically manage and govern the lifecycle of user access to applications, groups, and roles. It enables organizations to prove to auditors that they are managing access regularly, and to optimize user access. Essentially, it automates the task of reviewing and revoking stale access.
Why are Access Reviews Important?
The principle of least privilege is a cornerstone of good security. Over time, user permissions can accumulate beyond what is necessary for their role, leading to:
- Increased Security Risk: Stale access can be exploited by malicious actors.
- Compliance Challenges: Many regulations require regular attestation of access rights.
- Operational Overhead: Manual reviews are time-consuming and prone to errors.
- Reduced Shadow IT: Understanding and controlling application access.
