Question 650
A web server runs a vulnerable service but its FortiGate inbound rule lacks the IPS profile, so the vulnerability scan produces no corresponding IPS events. Which TWO complementary choices provide the appropriate response AND the key evidence for verifying it? Select TWO.
Explanation
Correct Answers
Inspect IPS sensor filter severity/category, signature IDs, action selection, policy assignment, SSL visibility and actual IPS event logs. This distinguishes the relevant FortiGate device, session or controller evidence. Signature severity alone does not guarantee relevance; a disabled or monitor-only IPS rule may log threats without blocking, and encrypted payloads need appropriate inspection. The corresponding action is: Build a FortiGate intrusion prevention sensor using supported signature filters, action overrides and protected-application context, then attach it to the correct policy. This is the verification portion of the required complementary pair. Scenario: A web server runs a vulnerable service but its FortiGate inbound rule lacks the IPS profile, so the vulnerability scan produces no corresponding IPS events.
Build a FortiGate intrusion prevention sensor using supported signature filters, action overrides and protected-application context, then attach it to the correct policy. This directly addresses the FortiOS configuration or response required by the case. Signature severity alone does not guarantee relevance; a disabled or monitor-only IPS rule may log threats without blocking, and encrypted payloads need appropriate inspection. Verify with: Inspect IPS sensor filter severity/category, signature IDs, action selection, policy assignment, SSL visibility and actual IPS event logs. This is the implementation portion of the required complementary pair. Scenario: A web server runs a vulnerable service but its FortiGate inbound rule lacks the IPS profile, so the vulnerability scan produces no corresponding IPS events.
Incorrect Answers
Inspect configured simple/wildcard/regex pattern type, URL filter order, exempt/action behavior, relevant hostname/path visibility and web-filter logs. This choice relates to Static URL filter ordering and wildcard match behavior, not the complementary implementation-and-evidence pair for the case. Implement: Build a FortiGate intrusion prevention sensor using supported signature filters, action overrides and protected-application context, then attach it to the correct policy. Check: Inspect IPS sensor filter severity/category, signature IDs, action selection, policy assignment, SSL visibility and actual IPS event logs. Scenario: A web server runs a vulnerable service but its FortiGate inbound rule lacks the IPS profile, so the vulnerability scan produces no corresponding IPS events.
Measure FortiOS IPS engine and appliance resource load under representative traffic before changing signature sets or SSL inspection scope, keeping protection while isolating bottlenecks. This choice relates to IPS process CPU demand and inspection capacity, not the complementary implementation-and-evidence pair for the case. Implement: Build a FortiGate intrusion prevention sensor using supported signature filters, action overrides and protected-application context, then attach it to the correct policy. Check: Inspect IPS sensor filter severity/category, signature IDs, action selection, policy assignment, SSL visibility and actual IPS event logs. Scenario: A web server runs a vulnerable service but its FortiGate inbound rule lacks the IPS profile, so the vulnerability scan produces no corresponding IPS events.
Only unauthorized application categories are blocked while monitored business tools generate usable visibility without unexpected interruption. This choice relates to Application control monitor versus block actions and exceptions, not the complementary implementation-and-evidence pair for the case. Implement: Build a FortiGate intrusion prevention sensor using supported signature filters, action overrides and protected-application context, then attach it to the correct policy. Check: Inspect IPS sensor filter severity/category, signature IDs, action selection, policy assignment, SSL visibility and actual IPS event logs. Scenario: A web server runs a vulnerable service but its FortiGate inbound rule lacks the IPS profile, so the vulnerability scan produces no corresponding IPS events.
