Question 690
At Ironwood Energy Cooperative, the FortiGate 7.6 security administration team encounters the following authorized operational case: a proxy-based web filter returns an unfamiliar browser denial page that conceals the intended company policy message. 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 web filter block page is generated by inspection settings rather than the remote website. The mechanism is relevant because the stated proxy web-filter response replacement incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to configure the supported replacement or block-message behavior for the assigned proxy inspection profile; verify it through this observed condition: a denied test category displays the approved explanatory message.
Incorrect Answers
Matching solely a well-known port is insufficient when traffic can use an alternate destination port explains a different situation, nonstandard application port, where a blocked application moves to a nondefault TCP port and bypasses a rule limited to the standard service object. It does not account for the specific observed proxy web-filter response replacement condition at Ironwood Energy Cooperative. The decisive mechanism here is: A web filter block page is generated by inspection settings rather than the remote website.
Identification alone does not necessarily rate-limit or block application throughput explains a different situation, streaming media bandwidth policy, where student video streaming consumes a WAN circuit despite an application-control profile configured only to monitor it. It does not account for the specific observed proxy web-filter response replacement condition at Ironwood Energy Cooperative. The decisive mechanism here is: A web filter block page is generated by inspection settings rather than the remote website.
An application may be terminated at inspection and produce security events different from successful traffic-session records explains a different situation, application control deny with no traffic log, where a denied file-transfer program is visible in application security events but the help desk expects a matching normal accepted-session log. It does not account for the specific observed proxy web-filter response replacement condition at Ironwood Energy Cooperative. The decisive mechanism here is: A web filter block page is generated by inspection settings rather than the remote website.
