Question 620
During a FortiAnalyzer incident investigation, the analysts observe: An application exhibits failed HTTPS sessions, and a security analyst sees generic traffic denies but no malware detections. Which ongoing operational control best reduces the risk of recurrence?
Explanation
Correct Answer
This safeguard directly addresses failed web requests caused by certificate error: Ensure certificate error diagnostics are available during SSL inspection change windows. The risk being prevented is: Connection failure and security detection are different causes; a missing malware log cannot identify a TLS or certificate root cause. A safeguard aimed at another fault would not control this issue.
Incorrect Answers
Generic HTTPS totals obscure application categories that may reveal unsanctioned file-sharing services. “Review category labels and business exceptions before claiming all detected cloud storage is policy-breaking” would remedy that alternative situation, but it would not correct the present issue: connection failure and security detection are different causes; a missing malware log cannot identify a TLS or certificate root cause.
“Exercise multi-product phishing investigation with controlled sample events and source-aware searches” is the supported response when email detection and subsequent web access must be correlated across distinct products using consistent user and time context. Here the decisive response is “Ensure certificate error diagnostics are available during SSL inspection change windows”, so that different intervention does not meet the stated requirement.
Different hostnames or cached endpoints can share an IP and different security profiles evaluate different request fields. “Avoid correlating alerts solely by shared destination IP when domain and URL context exists” applies to that other condition. The reported evidence is an application exhibits failed HTTPS sessions, and a security analyst sees generic traffic denies but no malware detections; this alternative would address the wrong dependency.
