Question 860
During a cross-team security policy review at Prairie Health Network, engineers say that they resolved this finding: Endpoint malware prevention blocks benign developer tools because every unsigned file receives the same response. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
Authorized tools execute and known malicious test objects remain blocked. This is the decisive evidence for the original problem: Endpoint malware prevention blocks benign developer tools because every unsigned file receives the same response. It verifies that the intended corrective control—Tune EPP policy by verified publisher, reputation, and controlled exceptions—works in the relevant environment; a completed change ticket alone would not prove the outcome at Prairie Health Network.
Incorrect Answers
A controlled suspicious process creates a trace and an analyst can isolate the endpoint. This would be relevant evidence for a different failure: A workstation has only signature-based antivirus and no visibility into suspicious processes after execution, usually addressed by Add EDR telemetry and response capability to complement preventive endpoint controls. It does not demonstrate that the current problem at Prairie Health Network was resolved. The specific required evidence is: Authorized tools execute and known malicious test objects remain blocked.
The protected device blocks known malware and retains investigation data for suspicious behavior. This would be relevant evidence for a different failure: A company purchases an EDR tool but expects it to replace every hardening, patching, and prevention measure, usually addressed by Combine EPP prevention, EDR detection and investigation, and baseline device security. It does not demonstrate that the current problem at Prairie Health Network was resolved. The specific required evidence is: Authorized tools execute and known malicious test objects remain blocked.
The event timeline shows parent-child execution and associated file activity. This would be relevant evidence for a different failure: Investigators cannot tell which process spawned a malicious downloader on a compromised laptop, usually addressed by Use endpoint process-tree telemetry and forensic context from an EDR solution. It does not demonstrate that the current problem at Prairie Health Network was resolved. The specific required evidence is: Authorized tools execute and known malicious test objects remain blocked.
