Question 550
At Maplewood Schools, the district IT security team administers FortiGate-based protection for school campuses and a central datacenter under requirements for student protection and restricted management interfaces. Following the approved change, the team must validate: Antivirus threats are not scanned on office-to-internet traffic because the FortiGate allow policy has no antivirus security profile attached. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
A harmless antivirus test file produces the documented detection or block event and normal downloads remain available. This outcome validates the intended correction for: Antivirus threats are not scanned on office-to-internet traffic because the FortiGate allow policy has no antivirus security profile attached. The associated approved corrective action is: Apply the approved antivirus profile and protocol options to the intended FortiGate security policy. The Maplewood Schools reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
The intended test path is denied and a separate approved page under the same hostname remains accessible. This would verify a separate corrective action: Use a supported URL matching rule with the correct path and priority where full HTTPS visibility is available. That separate change addresses: A web filtering rule blocks an entire public domain though only one known malicious subpath must be denied for the documented service. It does not validate the current Maplewood Schools issue: Antivirus threats are not scanned on office-to-internet traffic because the FortiGate allow policy has no antivirus security profile attached. The relevant acceptance evidence is: A harmless antivirus test file produces the documented detection or block event and normal downloads remain available.
The pinned application completes a valid secure connection while unrelated permitted HTTPS sessions still receive the required inspection. This would verify a separate corrective action: Create a narrowly scoped inspection exemption for the documented pinned service using appropriate destination and application checks. That separate change addresses: A business-critical certificate-pinned application fails after deep SSL inspection even though its TLS server certificate is otherwise valid. It does not validate the current Maplewood Schools issue: Antivirus threats are not scanned on office-to-internet traffic because the FortiGate allow policy has no antivirus security profile attached. The relevant acceptance evidence is: A harmless antivirus test file produces the documented detection or block event and normal downloads remain available.
A controlled IPS trigger shows a unique signature event, whereas a simple policy deny shows a separate firewall decision. This would verify a separate corrective action: Correlate IPS-specific events with the forward policy and test signature before reporting the detection mechanism. That separate change addresses: An analyst mistakes a FortiGate denied firewall-policy log for proof that an IPS signature blocked an exploit. It does not validate the current Maplewood Schools issue: Antivirus threats are not scanned on office-to-internet traffic because the FortiGate allow policy has no antivirus security profile attached. The relevant acceptance evidence is: A harmless antivirus test file produces the documented detection or block event and normal downloads remain available.
