An administrator has been granted top security clearance at a company. One day the administrator finds that certain confidential documents cannot be accessed. The administrator asks the IT team to verify the level of clearance and receives the confirmation that top security clearance is still valid. What could be the reason that the administrator cannot access the respective documents?
- The firewall rules are in conflict with the access rights of the user.
- The PKI key of the user is invalid.
- The principle of least privilege has been applied.
- The PKI certificate has been revoked.
| Explanation & Hint:
The principle of least privilege has been applied in the access control models. This would mean that, even though the employee has top security clearance to access the intelligence information, they would still not be given access to such information unless they needed it to be able to effectively perform their job duties. |
