Question 790
At Juniper Insurance, the FortiGate 7.6 security administration team encounters the following authorized operational case: an auditor cannot validate antivirus policy behavior without using real malware. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. What root condition most directly explains the described FortiGate symptom?
Explanation
Correct Answer
A standard benign test signature can exercise AV inspection behavior without deploying harmful code. The mechanism is relevant because the stated eicar detection acceptance incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to use the harmless industry-standard EICAR test artifact under a supervised authorized test; verify it through this observed condition: the EICAR test generates the expected FortiGate AV detection and log.
Incorrect Answers
A broad IPS sensor disablement would unnecessarily remove other exploit coverage explains a different situation, ips false-positive remediation, where a verified internal API is blocked after an IPS signature update although an authorized regression test shows no exploit. It does not account for the specific observed eicar detection acceptance condition at Juniper Insurance. The decisive mechanism here is: A standard benign test signature can exercise AV inspection behavior without deploying harmful code.
IPS protection is determined by which policy-path sessions traverse an enabled sensor explains a different situation, ips protecting internal segmentation, where lateral traffic between two application VLANs is allowed by policy but never inspected for known internal service exploits. It does not account for the specific observed eicar detection acceptance condition at Juniper Insurance. The decisive mechanism here is: A standard benign test signature can exercise AV inspection behavior without deploying harmful code.
Certificate verification depends on an up-to-date chain rather than just the hostname or leaf validity explains a different situation, expired intermediate after ca rotation, where fortiGate continues to trust an obsolete internal intermediate after the issuing CA changes, causing inconsistent SSL inspection results. It does not account for the specific observed eicar detection acceptance condition at Juniper Insurance. The decisive mechanism here is: A standard benign test signature can exercise AV inspection behavior without deploying harmful code.
