Question 770
Web-filter logs show a category deny for the server host while management interprets the record as proof of which encrypted document the user opened. Which FortiOS 7.6 configuration or corrective action is MOST appropriate?
Explanation
Correct Answer
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 directly addresses the FortiOS configuration or response required by the case. Certificate inspection does not expose all encrypted HTTP headers and paths; some modern encrypted client protocols reduce metadata availability. Verify with: Examine FortiGuard category decision, encrypted request behavior, SSL inspection profile, server name/certificate, protocol handling and web-filter event fields. Scenario: Web-filter logs show a category deny for the server host while management interprets the record as proof of which encrypted document the user opened.
Incorrect Answers
Use FortiGuard website categories and supported rating overrides to enforce approved access policy, documenting exceptions for miscategorized business sites. This addresses FortiGuard category ratings and controlled recategorization, but not the principal task of the described flow. 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. The better fit is: 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. Scenario: Web-filter logs show a category deny for the server host while management interprets the record as proof of which encrypted document the user opened.
Investigate FortiOS IPS detection and blocking evidence with signature context and false-positive testing, maintaining tightly bounded exclusions and tested action overrides. This addresses IPS signatures, logs and focused exception maintenance, but not the principal task of the described flow. An IPS exemption by broad source subnet or application category may remove protection beyond one false positive; signature updates can change what matches. The better fit is: 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. Scenario: Web-filter logs show a category deny for the server host while management interprets the record as proof of which encrypted document the user opened.
Evaluate supported TLS interception and QUIC/HTTP3 handling against FortiOS model capacity, application requirements and policy visibility instead of assuming every encrypted protocol follows the same inspection path. This addresses SSL inspection resources and QUIC protocol behavior, but not the principal task of the described flow. HTTP/3 uses QUIC over UDP and may not follow controls designed only for intercepted HTTPS over TCP; deep inspection consumes resources and capability varies by FortiOS build. The better fit is: 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. Scenario: Web-filter logs show a category deny for the server host while management interprets the record as proof of which encrypted document the user opened.
