What are two potential reasons for failed virus detection on HTTPS downloads in FortiGate? (Choose two)

The correct choice highlights a significant aspect of how SSL inspection interacts with virus detection processes on HTTPS downloads. When the selected SSL inspection profile has certificate inspection enabled, it may not be adequately inspecting the traffic for malware or viruses because the inspection could be terminating the secure session before it is analyzed. In cases where certificate inspection is applied, FortiGate might not fully decrypt and analyze the content if it doesn't trust the certificates involved or if there are issues in the SSL handshake process. This can lead to a failure in detecting viruses that could otherwise be captured during a complete inspection of the decrypted traffic.

FortiGate's antivirus engine being outdated is another plausible reason for detection failure. An outdated antivirus engine may not have the latest signatures, which could prevent the device from identifying new or evolving threats that are penetrating through HTTPS traffic. Keeping the antivirus definitions current is critical for effective threat detection, as new malware is constantly emerging.

The remaining options may contribute to detection issues as well but are not as directly related to the failure in virus detection as the choices identified. Issues arising from firewall policy misconfiguration may not directly correlate to HTTPS download analysis and inspection capabilities. Similarly, if a website is exempted from SSL inspection, it may still undergo scanning by other protocols; thus
