Question 270
At Brookside Manufacturing, the industrial security team is conducting a plant safety and IT security assessment under requirements for production continuity and controlled test windows. Following the approved correction, auditors require proof that: A ransomware readiness review finds backups stored on the same writable network share as production data. Which result BEST demonstrates successful remediation?
Explanation
Correct Answer
A controlled recovery test restores representative data even when ordinary production write credentials are unavailable. The observable result demonstrates that the documented condition, A ransomware readiness review finds backups stored on the same writable network share as production data. has been addressed. The planned remediation is: Maintain isolated immutable or offline backup copies with protected credentials and tested recovery procedures. This is a stronger validation than a saved ticket or unverified claim by Brookside Manufacturing.
Incorrect Answers
Affected hosts are identified by verified indicators and benign same-named files are not quarantined needlessly. That observation would verify another scenario: A suspicious binary's file hash matches a known malware family, but the team assumes every host with that filename is infected. The corrective step for that other scenario is: Validate full hash, signature and execution context rather than equating a file name with confirmed malicious behavior. But Brookside Manufacturing is evaluating: A ransomware readiness review finds backups stored on the same writable network share as production data. The necessary outcome is: A controlled recovery test restores representative data even when ordinary production write credentials are unavailable.
The incident record connects persistence and credential events to verifiable telemetry and corrective containment steps. That observation would verify another scenario: A server exhibits persistence and credential-access alerts but the incident ticket contains only a malware family label. The corrective step for that other scenario is: Investigate observed behavior and mapped tactics, isolate the host and record evidence supporting each incident conclusion. But Brookside Manufacturing is evaluating: A ransomware readiness review finds backups stored on the same writable network share as production data. The necessary outcome is: A controlled recovery test restores representative data even when ordinary production write credentials are unavailable.
A benign backup exercise no longer triggers false alarms while a controlled ransomware-like simulation still produces an alert. That observation would verify another scenario: A detection analyst suppresses every ransomware-related alert after one noisy false positive involving a backup process. The corrective step for that other scenario is: Tune the rule using validated process context and allowlisted behavior while retaining protection for genuine encryption anomalies. But Brookside Manufacturing is evaluating: A ransomware readiness review finds backups stored on the same writable network share as production data. The necessary outcome is: A controlled recovery test restores representative data even when ordinary production write credentials are unavailable.
