Insider threats are among the most difficult cybersecurity risks to detect and prevent. Whether intentional or accidental, they often arise from excessive or outdated access permissions. This is where User Access Reviews become crucial within a modern Identity Governance and Administration (IGA) strategy.
Understanding Insider Threats
Insider threats refer to risks posed by employees, contractors, or partners who have legitimate access to your systems and data. These threats can stem from:
-
Disgruntled employees misusing access
-
Former employees with still-active accounts
-
Careless insiders exposing sensitive data
-
Third-party vendors with unnecessary privileges
Without regular visibility into who has access to what, these risks multiply over time.
Why User Access Reviews Matter
User Access Reviews are structured, periodic checks to ensure that users have only the access they truly need. These reviews help detect:
-
Inactive accounts
-
Over-provisioned users
-
Access that no longer aligns with job roles
-
Privileges that should be revoked after role changes or terminations
By identifying and correcting such issues, access reviews significantly reduce the risk of insider misuse.
Strengthening IGA with Access Reviews
When integrated into your Identity Governance and Administration program, access reviews serve as a key control point. They enhance your IGA strategy by:
-
Enforcing least-privilege access policies
-
Providing audit-ready records for compliance
-
Ensuring consistent user lifecycle management
-
Improving response time to access-related anomalies
Automation tools within IGA platforms can further streamline access reviews, enabling real-time alerts and actions when risky access patterns are detected.
Conclusion
Preventing insider threats requires more than just firewalls and antivirus tools—it demands proactive identity governance. By embedding regular User Access Reviews into your Identity Governance and Administration processes, your organization strengthens its security posture, limits unauthorized access, and builds a culture of accountability
