Question 830
At Kingsford Regional Hospital, the FortiGate 7.6 security administration team encounters the following authorized operational case: a protected server is allowed by a firewall policy but known exploit test traffic never triggers an IPS event. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. What root condition most directly explains the described FortiGate symptom?
Explanation
Correct Answer
An IPS sensor not selected on a transit policy does not inspect that policy's sessions. The mechanism is relevant because the stated ips sensor missing from rule incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to attach the intended IPS sensor to the matching permit policy with supported inspection mode; verify it through this observed condition: a controlled authorized exploit-pattern simulation triggers the expected IPS policy event.
Incorrect Answers
TLS negotiation can fail before application inspection when no permitted protocol or cipher overlap exists explains a different situation, tls protocol negotiation support, where a legacy HTTPS endpoint fails during full inspection because it supports only TLS versions prohibited by organization policy. It does not account for the specific observed ips sensor missing from rule condition at Kingsford Regional Hospital. The decisive mechanism here is: An IPS sensor not selected on a transit policy does not inspect that policy's sessions.
HTTP URL filtering and DNS query filtering operate on different protocol events explains a different situation, dns-filter and web-filter distinction, where an administrator expects a web-filter category profile to block DNS lookups made directly through a separate resolver path. It does not account for the specific observed ips sensor missing from rule condition at Kingsford Regional Hospital. The decisive mechanism here is: An IPS sensor not selected on a transit policy does not inspect that policy's sessions.
Signature classification cannot identify all custom or obscured protocols automatically explains a different situation, unknown application coverage, where a custom encrypted application is allowed even though common application signatures are blocked by category. It does not account for the specific observed ips sensor missing from rule condition at Kingsford Regional Hospital. The decisive mechanism here is: An IPS sensor not selected on a transit policy does not inspect that policy's sessions.
