How to evaluate the effectiveness of asset access control measures?

To evaluate the effectiveness of asset access control measures, consider the following key aspects:

1. Access Compliance: Verify if access permissions align with policies and roles. For example, ensure only HR staff can access sensitive employee data.
2. Unauthorized Access Attempts: Monitor failed login attempts or access to restricted resources. A low number of such events indicates strong controls.
3. Audit Trails: Check if access logs are recorded and regularly reviewed. Logs should capture who accessed what, when, and from where.
4. Incident Response: Assess how quickly and effectively the system detects and mitigates breaches. For instance, if an unauthorized user tries to access a database, does the system block the attempt and alert administrators?

Example: A company implements role-based access control (RBAC) for its cloud storage. To evaluate effectiveness, it reviews logs and finds no unauthorized access attempts over three months, while auditors confirm permissions match job functions.

For cloud environments, Tencent Cloud CAM (Cloud Access Management) helps enforce granular access policies, monitor permissions, and generate audit reports to streamline evaluation.
