Question 530
An incident responder sees application detection events but not a blocked action and incorrectly concludes that the firewall stopped the suspicious upload. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.
Explanation
Correct Answers
Review application log signature name, action, profile override, FortiGuard signature version, client flow, SSL inspection and change history. This distinguishes the relevant FortiGate device, session or controller evidence. A single application signature hit may be insufficient to prove a user deliberately launched that program; classification and encrypted traffic can be imperfect. The corresponding action is: Investigate FortiOS application detection logs and signature revisions before creating narrowly scoped exclusions, ensuring legitimate traffic and policy intent remain visible. This is the verification portion of the required complementary pair. Scenario: An incident responder sees application detection events but not a blocked action and incorrectly concludes that the firewall stopped the suspicious upload.
Investigate FortiOS application detection logs and signature revisions before creating narrowly scoped exclusions, ensuring legitimate traffic and policy intent remain visible. This directly addresses the FortiOS configuration or response required by the case. A single application signature hit may be insufficient to prove a user deliberately launched that program; classification and encrypted traffic can be imperfect. Verify with: Review application log signature name, action, profile override, FortiGuard signature version, client flow, SSL inspection and change history. This is the implementation portion of the required complementary pair. Scenario: An incident responder sees application detection events but not a blocked action and incorrectly concludes that the firewall stopped the suspicious upload.
Incorrect Answers
Approved HTTPS content receives the intended inspection depth while unsupported or privacy-sensitive traffic follows explicit reviewed exceptions. This choice relates to FortiGate certificate inspection versus full SSL/SSH inspection, not the complementary implementation-and-evidence pair for the case. Implement: Investigate FortiOS application detection logs and signature revisions before creating narrowly scoped exclusions, ensuring legitimate traffic and policy intent remain visible. Check: Review application log signature name, action, profile override, FortiGuard signature version, client flow, SSL inspection and change history. Scenario: An incident responder sees application detection events but not a blocked action and incorrectly concludes that the firewall stopped the suspicious upload.
Choose monitor, pass, block or supported application control actions for specific signatures and business roles, validating whether a detected application is truly prevented from operating. This choice relates to Application control monitor versus block actions and exceptions, not the complementary implementation-and-evidence pair for the case. Implement: Investigate FortiOS application detection logs and signature revisions before creating narrowly scoped exclusions, ensuring legitimate traffic and policy intent remain visible. Check: Review application log signature name, action, profile override, FortiGuard signature version, client flow, SSL inspection and change history. Scenario: An incident responder sees application detection events but not a blocked action and incorrectly concludes that the firewall stopped the suspicious upload.
Check inspection CA selection, certificate lifetime and chain, endpoint trust-store deployment, private-key controls, browser warnings and handshake logs. This choice relates to FortiGate deep-inspection CA trust and certificate deployment, not the complementary implementation-and-evidence pair for the case. Implement: Investigate FortiOS application detection logs and signature revisions before creating narrowly scoped exclusions, ensuring legitimate traffic and policy intent remain visible. Check: Review application log signature name, action, profile override, FortiGuard signature version, client flow, SSL inspection and change history. Scenario: An incident responder sees application detection events but not a blocked action and incorrectly concludes that the firewall stopped the suspicious upload.
