Question 10
At Briarwood Property Group, a team reports that it corrected the following problem affecting tenant applications and facility services: A workstation begins executing a disguised program that installs an unauthorized remote access component. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
Endpoint telemetry shows containment and no unauthorized outbound command channel remains. This is the decisive evidence for the original problem: A workstation begins executing a disguised program that installs an unauthorized remote access component. It verifies that the intended corrective control—Isolate the endpoint, remove the malicious executable using approved response controls, and examine persistence—works in the relevant environment; a completed change ticket alone would not prove the outcome at Briarwood Property Group.
Incorrect Answers
Spraying attempts are throttled and account activity reveals no successful unauthorized sign-ins. This would be relevant evidence for a different failure: A vendor access portal experiences password spraying across many usernames from a few addresses, usually addressed by Apply identity risk detection, rate controls, and phishing-resistant MFA with investigation of attempted accounts. It does not demonstrate that the current problem at Briarwood Property Group was resolved. The specific required evidence is: Endpoint telemetry shows containment and no unauthorized outbound command channel remains.
Unauthorized object reads stop and fresh scoped credentials work only for intended operations. This would be relevant evidence for a different failure: Cloud audit records show an API token used from an unexpected geography to enumerate confidential objects, usually addressed by Disable the compromised token, investigate its scope, and rotate affected credentials before restoring least-privilege access. It does not demonstrate that the current problem at Briarwood Property Group was resolved. The specific required evidence is: Endpoint telemetry shows containment and no unauthorized outbound command channel remains.
A connection intercepted by a test relay fails authentication without exposing application data. This would be relevant evidence for a different failure: An attacker places a malicious relay between two hosts to read unprotected application traffic, usually addressed by Require authenticated encrypted transport and validate endpoint identities rather than trusting network proximity. It does not demonstrate that the current problem at Briarwood Property Group was resolved. The specific required evidence is: Endpoint telemetry shows containment and no unauthorized outbound command channel remains.
