Question 1140
During a security incident tabletop exercise at Vantage Travel, engineers say that they resolved this finding: A team blocks FTP exfiltration but ignores equivalent paths through secure chat and file-sharing apps. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
A protected data sample is stopped across relevant channels rather than just FTP. This is the decisive evidence for the original problem: A team blocks FTP exfiltration but ignores equivalent paths through secure chat and file-sharing apps. It verifies that the intended corrective control—Use application-aware egress policy and DLP across approved and unapproved transfer channels—works in the relevant environment; a completed change ticket alone would not prove the outcome at Vantage Travel.
Incorrect Answers
Unapproved outbound file-transfer traffic is denied and correlated with source activity. This would be relevant evidence for a different failure: An internal server opens unexpected outbound SSH/SCP sessions to unknown Internet destinations overnight, usually addressed by Apply egress controls and investigate host and flow telemetry for unauthorized transfer. It does not demonstrate that the current problem at Vantage Travel was resolved. The specific required evidence is: A protected data sample is stopped across relevant channels rather than just FTP.
The restricted file transfer is blocked or reviewed while permitted SaaS traffic continues. This would be relevant evidence for a different failure: An employee uploads a confidential file to personal cloud storage using an otherwise permitted HTTPS session, usually addressed by Use appropriate DLP and sanctioned-application policy with inspection consistent with privacy rules. It does not demonstrate that the current problem at Vantage Travel was resolved. The specific required evidence is: A protected data sample is stopped across relevant channels rather than just FTP.
The covert-transfer test creates an alert and cannot move meaningful protected data. This would be relevant evidence for a different failure: A malicious process attempts to leak data through ICMP payloads rather than common web ports, usually addressed by Monitor unusual ICMP volume and payload patterns and limit unneeded egress traffic. It does not demonstrate that the current problem at Vantage Travel was resolved. The specific required evidence is: A protected data sample is stopped across relevant channels rather than just FTP.
