Question 330
A ransomware indicator appears on a server and investigators need to trace the process that created suspicious files. Which Cisco security control or operational response BEST addresses the stated need?
Explanation
Correct Answer
Interpret Cisco Secure Endpoint detection events using file, process, device, event time, and connected-host context before declaring an infection scope. This control addresses the failure mechanism and narrows the enforcement boundary. An endpoint detection event records what the connector observed and did; a block, quarantine, detection, and retrospective verdict are distinct states. Confirm pre-change conditions using: Inspect file trajectory, device trajectory, hash reputation, user identity, process parentage, and action taken. Situation: A ransomware indicator appears on a server and investigators need to trace the process that created suspicious files.
Incorrect Answers
Use supported Cisco Secure Malware Analytics sandbox assessment to investigate suspicious files while distinguishing dynamic analysis from known-good reputation. This response applies to Cisco Secure Malware Analytics detonation evidence, not the controlling requirement in this case. Sandbox dynamic analysis records execution behavior in a controlled environment; a clean result cannot prove every variant is harmless. For this scenario, the targeted action is: Interpret Cisco Secure Endpoint detection events using file, process, device, event time, and connected-host context before declaring an infection scope. Situation: A ransomware indicator appears on a server and investigators need to trace the process that created suspicious files.
Isolate high-risk endpoints using approved EDR response while preserving evidence and controlled paths for incident handling. This response applies to Endpoint incident isolation and forensics, not the controlling requirement in this case. Endpoint isolation contains spread but can interrupt critical operations; response must balance urgency, containment scope, and evidence preservation. For this scenario, the targeted action is: Interpret Cisco Secure Endpoint detection events using file, process, device, event time, and connected-host context before declaring an infection scope. Situation: A ransomware indicator appears on a server and investigators need to trace the process that created suspicious files.
Prioritize Secure Endpoint alerts by severity, current host risk, file action, correlated detections, and business criticality. This response applies to Endpoint malware event prioritization, not the controlling requirement in this case. Alert counts alone do not establish incident severity; containment status and evidence of active execution change urgency. For this scenario, the targeted action is: Interpret Cisco Secure Endpoint detection events using file, process, device, event time, and connected-host context before declaring an infection scope. Situation: A ransomware indicator appears on a server and investigators need to trace the process that created suspicious files.
