Isaca CISM Practice Test 60

Question 590

A company considers paying an extortion demand without involving legal and executive risk authority. Which decision is BEST supported by the business and security evidence?

  1. Immediately contain active spread with authorized measures while preserving feasible evidence.
  2. Escalate the decision for legal, sanctions, business and recovery evaluation by authorized leaders.
  3. Verify isolated backup integrity and restoration before committing to recovery promises.
  4. Investigate and close the entry vector before returning affected systems to trusted operation.

Explanation

Correct Answer

B:

Extortion payment is not a routine technical remediation choice. This directly meets the requirement to govern ransomware extortion decisions.

Incorrect Answers

A:

Preventing further material loss takes priority when destructive activity is ongoing. That action would halt active ransomware propagation; it does not address the case's priority to govern ransomware extortion decisions.

C:

Recovery decisions need tested evidence that usable copies remain. This would help confirm ransomware recovery feasibility; the scenario instead requires a decision to govern ransomware extortion decisions.

D:

Restoration alone permits immediate reinfection if compromise paths remain. That action would prevent ransomware reinfection during recovery; it does not address the case's priority to govern ransomware extortion decisions.

Question 591

An incident closes with no documented owner for residual customer notification obligations. What is the MOST appropriate next action for the information security manager?

  1. Keep the case active or formally track remaining remediation before verified closure.
  2. Verify the corrected control under representative conditions before final acceptance.
  3. Record outstanding legal and business actions with accountable owners and due dates.
  4. Define risk-based closure criteria including follow-up detection and reassessment.

Explanation

Correct Answer

C:

Technical closure does not eliminate continued reporting responsibilities. This directly meets the requirement to preserve post-technical-closure obligations.

Incorrect Answers

A:

Detection closure status must not mask unfinished risk treatment. That action would avoid premature incident closure; it does not address the case's priority to preserve post-technical-closure obligations.

B:

Corrective actions need operating evidence to count as effective. It is primarily relevant when the need is to validate post-incident control improvements, rather than to preserve post-technical-closure obligations.

D:

Closure should reflect restored trust and ongoing visibility where needed. That action would ensure risk-aware incident completion; it does not address the case's priority to preserve post-technical-closure obligations.

Question 592

Repeated external breaches exploit the same untracked supplier connection. Which management response BEST addresses the stated risk or governance priority?

  1. Improve asset discovery and patch governance in addition to fixing the individual host.
  2. Examine systemic control weaknesses and organizational conditions alongside human actions.
  3. Trace the full attack chain and identify missed protective and detective controls.
  4. Address supplier access governance and monitoring rather than isolated indicators.

Explanation

Correct Answer

D:

Recurring attack paths indicate an unresolved systemic dependency. This directly meets the requirement to fix recurring supplier-origin security weaknesses.

Incorrect Answers

A:

Process weaknesses can reproduce similar gaps across systems. That action would remediate root causes of missed patching; it does not address the case's priority to fix recurring supplier-origin security weaknesses.

B:

Root-cause analysis should not stop at the most visible individual mistake. It is primarily relevant when the need is to identify systemic breach causes, rather than to fix recurring supplier-origin security weaknesses.

C:

Initial access is not the only cause of material compromise. This would help analyze full causal attack progression; the scenario instead requires a decision to fix recurring supplier-origin security weaknesses.

Question 593

A company distributes an unredacted incident analysis containing employee personal records to all staff. Which management action BEST meets the stated requirement?

  1. Share role-appropriate lessons while protecting confidential case evidence.
  2. Define action owners, target dates and measurable verification of improvement.
  3. Track closure and effectiveness of corrective actions after the review.
  4. Review business impact, decisions, effectiveness and improvement actions with stakeholders.

Explanation

Correct Answer

A:

Learning does not require unrestricted disclosure of sensitive investigation material. This directly meets the requirement to communicate lessons without overexposing evidence.

Incorrect Answers

B:

Lessons learned produce change only through accountable follow-through. It is primarily relevant when the need is to turn incident findings into corrective actions, rather than to communicate lessons without overexposing evidence.

C:

Improvement is evidenced by changed controls and reduced repeat exposure. This would help measure post-incident improvement outcomes; the scenario instead requires a decision to communicate lessons without overexposing evidence.

D:

Lessons learned must address enterprise outcomes, not just malware artifacts. That action would conduct an enterprise-focused post-incident review; it does not address the case's priority to communicate lessons without overexposing evidence.

Question 594

A finance worker transferred money following an impersonation email and the team focuses only on blocking a domain. Which decision is BEST supported by the business and security evidence?

  1. Preserve the message and assess sender, URL and delivery scope before disruptive action.
  2. Initiate fraud response, financial recall and credential investigation with relevant stakeholders.
  3. Remove malicious forwarding and revoke sessions while investigating lateral account activity.
  4. Search organization-wide delivery and interaction evidence to determine exposure.

Explanation

Correct Answer

B:

Business email compromise can require financial recovery beyond technical mail control. This directly meets the requirement to coordinate financial response to email fraud.

Incorrect Answers

A:

Evidence-led triage distinguishes malicious campaigns from harmless messages. That action would evaluate a reported suspicious email; it does not address the case's priority to coordinate financial response to email fraud.

C:

Mailbox persistence must be addressed alongside initial credential compromise. This would help eliminate malicious mailbox persistence; the scenario instead requires a decision to coordinate financial response to email fraud.

D:

Campaign scope may exceed the first reported user and drive response priorities. That action would assess enterprise-wide phishing spread; it does not address the case's priority to coordinate financial response to email fraud.

Question 595

A suspicious event triggers thousands of near-identical alerts that hide one real compromise. What is the MOST appropriate next action for the information security manager?

  1. Require relevant local telemetry and confidence evidence before case escalation.
  2. Restore monitoring coverage and validate data freshness before declaring full assurance.
  3. Tune narrowly verified duplicates while preserving evidence and attack coverage.
  4. Create verified detection logic from observed behaviors and safely deploy with monitoring.

Explanation

Correct Answer

C:

Noise reduction should not suppress genuine escalation signals. This directly meets the requirement to reduce incident alert noise without blind spots.

Incorrect Answers

A:

Indicators alone do not prove that an organization is compromised. That action would validate intelligence-driven incident activation; it does not address the case's priority to reduce incident alert noise without blind spots.

B:

Missing alerts may represent a blind spot rather than absence of malicious activity. It is primarily relevant when the need is to avoid false closure from missing security telemetry, rather than to reduce incident alert noise without blind spots.

D:

Confirmed incident evidence can strengthen coverage for emerging tactics. That action would improve detections from active attack evidence; it does not address the case's priority to reduce incident alert noise without blind spots.

Question 596

A customer-facing outage is attributed to attack activity, but business continuity staff receive no alert. Which management response BEST addresses the stated risk or governance priority?

  1. Follow high-impact approval and emergency escalation rules with safety decision makers.
  2. Trigger on-call escalation with accountable ownership and bounded response SLAs.
  3. Notify privacy and legal decision owners through the defined incident escalation path.
  4. Escalate to the enterprise incident commander and continuity leadership promptly.

Explanation

Correct Answer

D:

Response must coordinate cyber containment with customer-service operations. This directly meets the requirement to involve continuity leadership in material incidents.

Incorrect Answers

A:

Technical ability does not equal business authority to accept major disruption. That action would obtain lawful high-impact containment approval; it does not address the case's priority to involve continuity leadership in material incidents.

B:

Defined coverage prevents critical incidents being abandoned between shifts. It is primarily relevant when the need is to guarantee after-hours incident ownership, rather than to involve continuity leadership in material incidents.

C:

Specialized obligations require responsible stakeholders beyond IT operations. This would help escalate potential regulatory incidents; the scenario instead requires a decision to involve continuity leadership in material incidents.

Question 597

A public cloud storage bucket exposes records, but the team cannot distinguish deliberate public sharing from a misconfiguration. Which management action BEST meets the stated requirement?

  1. Preserve configuration history, access logs and owner intent before assigning root cause.
  2. Evaluate shared-responsibility boundaries and customer control implications.
  3. Preserve independent evidence and prevent further log tampering through authorized controls.
  4. Correlate identity, API, resource and region evidence to scope affected assets.

Explanation

Correct Answer

A:

Cloud exposure investigations need context beyond a single public-permission flag. This directly meets the requirement to investigate cloud data exposure cause.

Incorrect Answers

B:

Provider incidents can affect customer obligations and resilience even without direct configuration changes. It is primarily relevant when the need is to assess customer impact of cloud provider incidents, rather than to investigate cloud data exposure cause.

C:

Cloud audit evidence can be targeted to conceal attacker activity. This would help protect cloud investigation evidence integrity; the scenario instead requires a decision to investigate cloud data exposure cause.

D:

Cloud incidents can cross services and jurisdictions using one principal. That action would determine compromised cloud identity blast radius; it does not address the case's priority to investigate cloud data exposure cause.

Question 598

After restoring files, the company plans to resume service without identifying the initial access route. Which decision is BEST supported by the business and security evidence?

  1. Escalate the decision for legal, sanctions, business and recovery evaluation by authorized leaders.
  2. Investigate and close the entry vector before returning affected systems to trusted operation.
  3. Immediately contain active spread with authorized measures while preserving feasible evidence.
  4. Verify isolated backup integrity and restoration before committing to recovery promises.

Explanation

Correct Answer

B:

Restoration alone permits immediate reinfection if compromise paths remain. This directly meets the requirement to prevent ransomware reinfection during recovery.

Incorrect Answers

A:

Extortion payment is not a routine technical remediation choice. That action would govern ransomware extortion decisions; it does not address the case's priority to prevent ransomware reinfection during recovery.

C:

Preventing further material loss takes priority when destructive activity is ongoing. This would help halt active ransomware propagation; the scenario instead requires a decision to prevent ransomware reinfection during recovery.

D:

Recovery decisions need tested evidence that usable copies remain. That action would confirm ransomware recovery feasibility; it does not address the case's priority to prevent ransomware reinfection during recovery.

Question 599

An emergency workaround permits handwritten transactions but no post-crisis reconciliation has been designed. What is the MOST appropriate next action for the information security manager?

  1. Coordinate proportionate containment with patient-safety and continuity decision owners.
  2. Activate out-of-band crisis communication and alternate operational coordination.
  3. Track manual work with audit controls and verify reconciliation during recovery.
  4. Activate alternate business processes and reconcile restored transactions before full restart.

Explanation

Correct Answer

C:

Temporary continuity processes must preserve integrity and accountability. This directly meets the requirement to ensure recovery from manual continuity operations.

Incorrect Answers

A:

Immediate technical isolation must consider unacceptable business and human harm. That action would balance containment and critical service continuity; it does not address the case's priority to ensure recovery from manual continuity operations.

B:

Response needs channels independent of compromised production infrastructure. It is primarily relevant when the need is to maintain crisis command during communications failure, rather than to ensure recovery from manual continuity operations.

D:

Business continuity addresses outcomes beyond infrastructure availability. That action would bridge cyber recovery with business operating continuity; it does not address the case's priority to ensure recovery from manual continuity operations.

Question 600

A low-severity alert gains evidence of privileged credential use on critical systems. Which management response BEST addresses the stated risk or governance priority?

  1. Validate evidence, affected identities and plausible attack paths before final classification.
  2. Correlate the indicator with relevant local evidence before escalating an incident.
  3. Prioritize investigation by credible business impact, confidence and propagation risk.
  4. Reassess severity, preserve context and trigger appropriate escalation.

Explanation

Correct Answer

D:

Triage priority must adapt when the attack scope and consequence grow. This directly meets the requirement to elevate response after high-impact evidence.

Incorrect Answers

A:

Triage distinguishes a detection signal from confirmed compromise. That action would avoid premature breach declaration; it does not address the case's priority to elevate response after high-impact evidence.

B:

Threat intelligence is a lead, not proof of local compromise. It is primarily relevant when the need is to verify local relevance of threat indicators, rather than to elevate response after high-impact evidence.

C:

Response effort should follow material exposure rather than first-in queue order. This would help triage competing security alerts by impact; the scenario instead requires a decision to elevate response after high-impact evidence.
