Question 10
An admin receives a user-reported phishing message but treats its subject line as enough evidence to quarantine similar emails. The change owner plans to: Analyze the email headers, sender authentication and threat verdict before scoping campaign response. Which additional safeguard is most specific to this implementation?
Explanation
Correct Answer
The specific rollout control is Use authorized evidence handling and review false-positive impact before broad remediation. It protects the proposed intervention 'Analyze the email headers, sender authentication and threat verdict before scoping campaign response.' against the failure mode that subject lines alone are weak identifiers for a phishing campaign. Success should also be checked through: The confirmed indicator set identifies malicious variants without matching legitimate unrelated messages.

Historical reports do not automatically route real-time operational notifications. A phishing investigation needs headers, URLs, attachments and related signals rather than matching mail subjects and quarantining indiscriminately.
Threat policies may be scoped to users, groups and domains and require explicit coverage verification. The proposed change also needs protection against this risk: Subject lines alone are weak identifiers for a phishing campaign. The applicable safeguard is: Use authorized evidence handling and review false-positive impact before broad remediation.
