Question 280
Following a controlled FortiClient security change, the issue is: A new proxy policy accepts unmanaged clients because its fallback rule is permissive. What test result best verifies the solution?
Explanation
Correct Answer
A closeout check must verify effective behavior, not merely that a management form was saved. Only the intended enrolled healthy identity gains access; invalid and unknown cases are denied. This supports the remedy exercise positive and negative identity and posture cases for the protected ZTNA resource. because application access controls need negative testing to demonstrate least-privilege enforcement.
Incorrect Answers
The alternate choice relates to 'A remote application is inaccessible because the device's operating system check yields an unexpected posture result.' It would prompt trace the FortiClient security posture evaluation through EMS tag assignment to FortiGate matching. The current issue instead requires exercise positive and negative identity and posture cases for the protected ZTNA resource.
That option would be better suited to the separate incident 'An application proxy allows every enrolled device regardless of current health checks.' Its supporting principle is ZTNA authorization can use application-specific trust signals rather than blanket network location alone. In this case the key condition is application access controls need negative testing to demonstrate least-privilege enforcement.
The distractor addresses a related but distinct failure: 'An administrator changes a proxy rule to Any Service to troubleshoot a single HTTPS application.' The current technical boundary is application access controls need negative testing to demonstrate least-privilege enforcement. and the required evidence is Only the intended enrolled healthy identity gains access; invalid and unknown cases are denied.
