Question 900
During a security incident tabletop exercise at Aster Mutual, engineers say that they resolved this finding: A managed laptop falls out of compliance after its endpoint security agent is disabled. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
The changed posture removes sensitive access until the agent is restored. This is the decisive evidence for the original problem: A managed laptop falls out of compliance after its endpoint security agent is disabled. It verifies that the intended corrective control—Reassess device state on relevant sessions and enforce quarantine or restricted remediation access—works in the relevant environment; a completed change ticket alone would not prove the outcome at Aster Mutual.
Incorrect Answers
Missing posture results cannot grant unrestricted access and users receive clear remediation guidance. This would be relevant evidence for a different failure: Posture assessment reports 'unknown' for a device and policy automatically treats it as compliant, usually addressed by Fail safely or limit access until posture evidence is available, with an approved remediation path. It does not demonstrate that the current problem at Aster Mutual was resolved. The specific required evidence is: The changed posture removes sensitive access until the agent is restored.
A compliant device passes relevant checks while actual high-risk devices remain blocked. This would be relevant evidence for a different failure: An employee's fully patched workstation fails a posture check because the policy requires an irrelevant platform control, usually addressed by Align posture rules to supported device classes and document justified exceptions. It does not demonstrate that the current problem at Aster Mutual was resolved. The specific required evidence is: The changed posture removes sensitive access until the agent is restored.
Only properly enrolled or explicitly approved devices establish sensitive sessions. This would be relevant evidence for a different failure: A contractor's unmanaged computer connects through VPN despite a requirement for device certificate enrollment, usually addressed by Check device identity and registration as part of conditional access or posture evaluation. It does not demonstrate that the current problem at Aster Mutual was resolved. The specific required evidence is: The changed posture removes sensitive access until the agent is restored.
