Question 610
At Harborview Energy Cooperative, the FortiGate 7.6 security administration team encounters the following authorized operational case: a branch FortiGate experiences significant CPU load after deep inspection is activated for every workstation. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. What root condition most directly explains the described FortiGate symptom?
Explanation
Correct Answer
Cryptographic interception imposes measurable processing overhead compared with certificate-only checks. The mechanism is relevant because the stated ssl deep inspection performance incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to scope full decryption to required traffic and verify hardware, cipher and capacity support; verify it through this observed condition: peak-load testing maintains approved latency and expected security visibility.
Incorrect Answers
Global category blocking can affect legitimate sites when ratings do not reflect the business exception explains a different situation, web filter category override, where a business-critical approved portal is classified under a FortiGuard category the organization normally blocks. It does not account for the specific observed ssl deep inspection performance condition at Harborview Energy Cooperative. The decisive mechanism here is: Cryptographic interception imposes measurable processing overhead compared with certificate-only checks.
General website category allow or deny does not necessarily enforce safe-search settings inside allowed search engines explains a different situation, safe search enforcement, where school policy requires safe-search behavior for supported search services but only generic category blocking is configured. It does not account for the specific observed ssl deep inspection performance condition at Harborview Energy Cooperative. The decisive mechanism here is: Cryptographic interception imposes measurable processing overhead compared with certificate-only checks.
A broad exemption can suppress inspection for unrelated traffic sharing the allowed domain scope explains a different situation, webfilter exemption policy scope, where a site-level SSL inspection exemption expands to an entire content-delivery domain and unexpectedly bypasses other security scanning. It does not account for the specific observed ssl deep inspection performance condition at Harborview Energy Cooperative. The decisive mechanism here is: Cryptographic interception imposes measurable processing overhead compared with certificate-only checks.
