Isaca CISM Practice Test 59

Question 580

A ransomware group claims it deleted backups but the organization has untested recovery copies. Which management response BEST addresses the stated risk or governance priority?

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

Explanation

Correct Answer

D:

Recovery decisions need tested evidence that usable copies remain. This directly meets the requirement to confirm ransomware recovery feasibility.

Incorrect Answers

A:

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 confirm ransomware recovery feasibility.

B:

Preventing further material loss takes priority when destructive activity is ongoing. It is primarily relevant when the need is to halt active ransomware propagation, rather than to confirm ransomware recovery feasibility.

C:

Extortion payment is not a routine technical remediation choice. This would help govern ransomware extortion decisions; the scenario instead requires a decision to confirm ransomware recovery feasibility.

Question 581

A whistleblower report alleges misuse by an executive who normally oversees investigations. Which management action BEST meets the stated requirement?

  1. Appoint independent investigative authority and protect confidentiality from conflicted managers.
  2. Verify work authorization and business context before deciding the activity is malicious.
  3. Restrict the appropriate privileges and preserve evidence under legal and HR guidance.
  4. Apply need-to-know access and approved confidential case communications.

Explanation

Correct Answer

A:

Credible investigations require independence from potentially implicated leadership. This directly meets the requirement to prevent conflicts in executive insider investigations.

Incorrect Answers

B:

Behavior anomalies are not proof of misconduct without context. It is primarily relevant when the need is to fairly evaluate suspicious insider data movement, rather than to prevent conflicts in executive insider investigations.

C:

Coordinated action protects evidence while respecting employment and legal obligations. This would help contain suspected privileged insider misuse; the scenario instead requires a decision to prevent conflicts in executive insider investigations.

D:

Premature disclosure can harm fairness and evidence integrity. That action would preserve confidentiality in insider investigations; it does not address the case's priority to prevent conflicts in executive insider investigations.

Question 582

A provider reports compromised customer data but refuses to release relevant incident timestamps. Which decision is BEST supported by the business and security evidence?

  1. Assess shared credentials and downstream access before reconnecting services.
  2. Invoke contractual cooperation and evidence obligations with legal escalation.
  3. Coordinate jurisdiction-specific notifications and verified facts across responsible parties.
  4. Establish joint event chronology, evidence owners and reconciliation process.

Explanation

Correct Answer

B:

Supplier evidence is needed for the customer's own impact and notification decisions. This directly meets the requirement to obtain necessary supplier incident evidence.

Incorrect Answers

A:

Partner recovery does not guarantee customer integration trust. That action would safely reconnect a recovered supplier; it does not address the case's priority to obtain necessary supplier incident evidence.

C:

Shared service incidents can activate distinct customer reporting obligations. This would help coordinate multi-jurisdiction supplier incident disclosures; the scenario instead requires a decision to obtain necessary supplier incident evidence.

D:

Distributed incidents require compatible evidence and coordinated attribution. That action would reconcile cross-supplier incident timelines; it does not address the case's priority to obtain necessary supplier incident evidence.

Question 583

An incident playbook creates duplicate external tickets whenever alerts are retried. What is the MOST appropriate next action for the information security manager?

  1. Remove or replace the integration with an authorized secured destination.
  2. Add scoped entity validation and approval for disruptive identity actions.
  3. Make ticket creation idempotent using a stable incident identity.
  4. Sequence evidence preservation before destructive steps where safe.

Explanation

Correct Answer

C:

Repeated automation triggers should not create redundant work or inconsistent ownership. This directly meets the requirement to prevent duplicate automated incident records.

Incorrect Answers

A:

Incident workflows can become data egress paths if integrations are not governed. That action would prevent unapproved automation data disclosure; it does not address the case's priority to prevent duplicate automated incident records.

B:

Incorrect automation can create broad outages if targets are not verified. It is primarily relevant when the need is to constrain high-impact incident automation, rather than to prevent duplicate automated incident records.

D:

Response automation must balance remediation speed with investigative integrity. That action would retain evidence in automated incident handling; it does not address the case's priority to prevent duplicate automated incident records.

Question 584

A cross-region cyber attack disrupts both primary and backup contact systems. Which management response BEST addresses the stated risk or governance priority?

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

Explanation

Correct Answer

D:

Response needs channels independent of compromised production infrastructure. This directly meets the requirement to maintain crisis command during communications failure.

Incorrect Answers

A:

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 maintain crisis command during communications failure.

B:

Temporary continuity processes must preserve integrity and accountability. It is primarily relevant when the need is to ensure recovery from manual continuity operations, rather than to maintain crisis command during communications failure.

C:

Immediate technical isolation must consider unacceptable business and human harm. This would help balance containment and critical service continuity; the scenario instead requires a decision to maintain crisis command during communications failure.

Question 585

A log export uses timestamps without timezone references from several regions. Which management action BEST meets the stated requirement?

  1. Preserve original timestamps and normalize chronology with documented offsets.
  2. Move evidence into approved restricted storage with custody, integrity and access records.
  3. Balance urgent containment with feasible volatile acquisition under the incident command decision.
  4. Confirm lawful disclosure scope and authorize controlled evidence exchange.

Explanation

Correct Answer

A:

Time interpretation is essential to reconstruct cross-system attack sequence. This directly meets the requirement to establish accurate forensic incident timeline.

Incorrect Answers

B:

Defensible evidence requires attributable handling and integrity controls. It is primarily relevant when the need is to restore forensic evidence handling accountability, rather than to establish accurate forensic incident timeline.

C:

Preservation is valuable but should not allow preventable material damage. This would help decide evidence collection versus urgent containment; the scenario instead requires a decision to establish accurate forensic incident timeline.

D:

Incident urgency does not remove privacy and contractual sharing restrictions. That action would protect privacy in forensic evidence sharing; it does not address the case's priority to establish accurate forensic incident timeline.

Question 586

The SOC exhausts its personnel during a prolonged regional cyber campaign. Which decision is BEST supported by the business and security evidence?

  1. Coordinate under an enterprise incident command while retaining unit-specific action owners.
  2. Activate planned surge staffing, shift rotation and external support.
  3. Allocate resources by business impact, propagation risk and mandated deadlines.
  4. Correlate evidence and preserve high-consequence incident focus while triaging noise.

Explanation

Correct Answer

B:

Sustainable response requires continuity of capable staff over extended operations. This directly meets the requirement to sustain incident handling during a prolonged crisis.

Incorrect Answers

A:

Shared cause and dependency warrant unified priorities and communication. That action would coordinate common-cause multi-unit incidents; it does not address the case's priority to sustain incident handling during a prolonged crisis.

C:

Incident priorities should reflect enterprise consequence and urgency. This would help prioritize competing incidents under resource pressure; the scenario instead requires a decision to sustain incident handling during a prolonged crisis.

D:

Response allocation should resist distraction and follow real enterprise impact. That action would avoid diversion from material concurrent attacks; it does not address the case's priority to sustain incident handling during a prolonged crisis.

Question 587

A containment playbook deletes suspect files before their hashes and metadata are recorded. What is the MOST appropriate next action for the information security manager?

  1. Make ticket creation idempotent using a stable incident identity.
  2. Add scoped entity validation and approval for disruptive identity actions.
  3. Sequence evidence preservation before destructive steps where safe.
  4. Remove or replace the integration with an authorized secured destination.

Explanation

Correct Answer

C:

Response automation must balance remediation speed with investigative integrity. This directly meets the requirement to retain evidence in automated incident handling.

Incorrect Answers

A:

Repeated automation triggers should not create redundant work or inconsistent ownership. That action would prevent duplicate automated incident records; it does not address the case's priority to retain evidence in automated incident handling.

B:

Incorrect automation can create broad outages if targets are not verified. It is primarily relevant when the need is to constrain high-impact incident automation, rather than to retain evidence in automated incident handling.

D:

Incident workflows can become data egress paths if integrations are not governed. That action would prevent unapproved automation data disclosure; it does not address the case's priority to retain evidence in automated incident handling.

Question 588

A responder bypasses governance and individually authorizes shutdown of a safety-critical control system. Which management response BEST addresses the stated risk or governance priority?

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

Explanation

Correct Answer

D:

Technical ability does not equal business authority to accept major disruption. This directly meets the requirement to obtain lawful high-impact containment approval.

Incorrect Answers

A:

Specialized obligations require responsible stakeholders beyond IT operations. That action would escalate potential regulatory incidents; it does not address the case's priority to obtain lawful high-impact containment approval.

B:

Response must coordinate cyber containment with customer-service operations. It is primarily relevant when the need is to involve continuity leadership in material incidents, rather than to obtain lawful high-impact containment approval.

C:

Defined coverage prevents critical incidents being abandoned between shifts. This would help guarantee after-hours incident ownership; the scenario instead requires a decision to obtain lawful high-impact containment approval.

Question 589

An external connector in a response workflow sends confidential indicators to an unapproved endpoint. Which management action BEST meets the stated requirement?

  1. Remove or replace the integration with an authorized secured destination.
  2. Make ticket creation idempotent using a stable incident identity.
  3. Sequence evidence preservation before destructive steps where safe.
