Question 50
A security architect enables every IPS signature on a sensitive OT segment without testing false-positive and latency impacts on legacy industrial protocols. Which observable result BEST demonstrates that the intended FortiGate security or connectivity requirement is satisfied?
Explanation
Correct Answer
A controlled benign exploit simulation triggers the expected IPS action while legitimate application transactions continue under tested exclusions. This is the operational validation outcome rather than merely an enabled setting. 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. Scenario: A security architect enables every IPS signature on a sensitive OT segment without testing false-positive and latency impacts on legacy industrial protocols.
Incorrect Answers
The selected IPS policy blocks intended known threats with acceptable measured latency and resource load under real peak conditions. This result would test IPS process CPU demand and inspection capacity but does not demonstrate the desired FortiGate outcome here. Verify instead: A controlled benign exploit simulation triggers the expected IPS action while legitimate application transactions continue under tested exclusions. Scenario: A security architect enables every IPS signature on a sensitive OT segment without testing false-positive and latency impacts on legacy industrial protocols.
Permitted test downloads receive the intended malware verdict, while excluded sensitive services keep documented and limited inspection behavior. This result would test HTTPS malware scanning with controlled exception validation but does not demonstrate the desired FortiGate outcome here. Verify instead: A controlled benign exploit simulation triggers the expected IPS action while legitimate application transactions continue under tested exclusions. Scenario: A security architect enables every IPS signature on a sensitive OT segment without testing false-positive and latency impacts on legacy industrial protocols.
The targeted false positive no longer interrupts an approved service, while exploit attempts retain blocking coverage and traceable alerts. This result would test IPS signatures, logs and focused exception maintenance but does not demonstrate the desired FortiGate outcome here. Verify instead: A controlled benign exploit simulation triggers the expected IPS action while legitimate application transactions continue under tested exclusions. Scenario: A security architect enables every IPS signature on a sensitive OT segment without testing false-positive and latency impacts on legacy industrial protocols.
