Question 420
A company changes a firewall from proxy-based to flow-based inspection without checking AV profile behavior and discovers different treatment of archived downloads. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.
Explanation
Correct Answers
Apply FortiOS antivirus profiles and protocol options in the supported inspection mode on the relevant firewall policies, with suitable FortiGuard definitions and HTTPS visibility. This directly addresses the FortiOS configuration or response required by the case. An antivirus profile can only scan content visible in its inspection path and within supported protocol or size limits; a scanner configured but unattached is ineffective. Verify with: Check AV profile action, inspection mode, protocol handling, signature version, SSL inspection profile, matched policy and antivirus log. This is the implementation portion of the required complementary pair. Scenario: A company changes a firewall from proxy-based to flow-based inspection without checking AV profile behavior and discovers different treatment of archived downloads.
Check AV profile action, inspection mode, protocol handling, signature version, SSL inspection profile, matched policy and antivirus log. This distinguishes the relevant FortiGate device, session or controller evidence. An antivirus profile can only scan content visible in its inspection path and within supported protocol or size limits; a scanner configured but unattached is ineffective. The corresponding action is: Apply FortiOS antivirus profiles and protocol options in the supported inspection mode on the relevant firewall policies, with suitable FortiGuard definitions and HTTPS visibility. This is the verification portion of the required complementary pair. Scenario: A company changes a firewall from proxy-based to flow-based inspection without checking AV profile behavior and discovers different treatment of archived downloads.
Incorrect Answers
Inspect SSL inspection mode, matched policy, negotiated TLS version, inspected application certificate, session log and target protocol support. This choice relates to FortiGate certificate inspection versus full SSL/SSH inspection, not the complementary implementation-and-evidence pair for the case. Implement: Apply FortiOS antivirus profiles and protocol options in the supported inspection mode on the relevant firewall policies, with suitable FortiGuard definitions and HTTPS visibility. Check: Check AV profile action, inspection mode, protocol handling, signature version, SSL inspection profile, matched policy and antivirus log. Scenario: A company changes a firewall from proxy-based to flow-based inspection without checking AV profile behavior and discovers different treatment of archived downloads.
Approved business applications remain usable while signatures identify and handle prohibited applications with traceable events. This choice relates to Application control signature matching and required visibility, not the complementary implementation-and-evidence pair for the case. Implement: Apply FortiOS antivirus profiles and protocol options in the supported inspection mode on the relevant firewall policies, with suitable FortiGuard definitions and HTTPS visibility. Check: Check AV profile action, inspection mode, protocol handling, signature version, SSL inspection profile, matched policy and antivirus log. Scenario: A company changes a firewall from proxy-based to flow-based inspection without checking AV profile behavior and discovers different treatment of archived downloads.
Validate FortiGuard AV updates and correlate malware detection logs to specific profiles and quarantines, applying safe containment rather than relying on a stale signature database. This choice relates to FortiGuard antivirus signature freshness and incident response, not the complementary implementation-and-evidence pair for the case. Implement: Apply FortiOS antivirus profiles and protocol options in the supported inspection mode on the relevant firewall policies, with suitable FortiGuard definitions and HTTPS visibility. Check: Check AV profile action, inspection mode, protocol handling, signature version, SSL inspection profile, matched policy and antivirus log. Scenario: A company changes a firewall from proxy-based to flow-based inspection without checking AV profile behavior and discovers different treatment of archived downloads.
