Question 340
A category-rating lookup succeeds from FortiGate, yet policy enforcement differs because an administrator modified a local category override without approval. Which FortiOS 7.6 configuration or corrective action is MOST appropriate?
Explanation
Correct Answer
Use FortiGuard website categories and supported rating overrides to enforce approved access policy, documenting exceptions for miscategorized business sites. This directly addresses the FortiOS configuration or response required by the case. Category-based filtering is only as accurate as current rating data and profile ordering; an override for one domain can affect all paths hosted there. Verify with: Inspect URL rating lookup, category database update, applied web filter rule, local rating override, browser result and web-filter log. Scenario: A category-rating lookup succeeds from FortiGate, yet policy enforcement differs because an administrator modified a local category override without approval.
Incorrect Answers
Choose certificate-only or supported deep SSL/SSH inspection according to required visibility and data-handling policy, assigning the correct profile to matching firewall policies. This addresses FortiGate certificate inspection versus full SSL/SSH inspection, but not the principal task of the described flow. Certificate-only inspection cannot read encrypted HTTP payloads; full SSL inspection introduces endpoint trust, protocol compatibility and privacy considerations. The better fit is: Use FortiGuard website categories and supported rating overrides to enforce approved access policy, documenting exceptions for miscategorized business sites. Scenario: A category-rating lookup succeeds from FortiGate, yet policy enforcement differs because an administrator modified a local category override without approval.
Correlate TLS metadata visibility, SNI or certificate names and FortiOS web-filter logs to determine when domain-only versus full-URL controls are technically enforceable. This addresses HTTPS web filtering hostname limitations and logging, but not the principal task of the described flow. Certificate inspection does not expose all encrypted HTTP headers and paths; some modern encrypted client protocols reduce metadata availability. The better fit is: Use FortiGuard website categories and supported rating overrides to enforce approved access policy, documenting exceptions for miscategorized business sites. Scenario: A category-rating lookup succeeds from FortiGate, yet policy enforcement differs because an administrator modified a local category override without approval.
Apply narrowly scoped, auditable SSL-inspection exclusions for supported certificate-pinned or regulated applications without disabling inspection for every other destination. This addresses Targeted SSL inspection exclusions and privacy controls, but not the principal task of the described flow. Broad category-level SSL exemptions can create large visibility gaps; an exception should be limited to the actual affected flow and justified by policy. The better fit is: Use FortiGuard website categories and supported rating overrides to enforce approved access policy, documenting exceptions for miscategorized business sites. Scenario: A category-rating lookup succeeds from FortiGate, yet policy enforcement differs because an administrator modified a local category override without approval.
