Isaca CISM Practice Test 58

Question 570

An incident affects vulnerable servers and teams rebuild them without fixing the exploited configuration. Which decision is BEST supported by the business and security evidence?

  1. Revoke relevant sessions and tokens while resetting affected credentials.
  2. Correct the root vulnerability or configuration gap before reconnecting rebuilt systems.
  3. Identify all affected integration permissions and revoke unauthorized access enterprise-wide.
  4. Remove verified persistence mechanisms and validate with continued monitoring.

Explanation

Correct Answer

B:

Recovery without fixing the exploit path risks immediate recurrence. This directly meets the requirement to remove initial access vulnerabilities before recovery.

Incorrect Answers

A:

Credential changes alone may not end existing authenticated attacker sessions. That action would eliminate persistent stolen-session access; it does not address the case's priority to remove initial access vulnerabilities before recovery.

C:

Persistence through shared integrations can survive local cleanup. This would help eradicate cross-application malicious integrations; the scenario instead requires a decision to remove initial access vulnerabilities before recovery.

D:

Eradication must eliminate the source of reinfection, not only a detected payload. That action would eradicate endpoint persistence; it does not address the case's priority to remove initial access vulnerabilities before recovery.

Question 571

An attacker creates an unauthorized mailbox forwarding rule after stealing credentials. What is the MOST appropriate next action for the information security manager?

  1. Initiate fraud response, financial recall and credential investigation with relevant stakeholders.
  2. Preserve the message and assess sender, URL and delivery scope before disruptive action.
  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

C:

Mailbox persistence must be addressed alongside initial credential compromise. This directly meets the requirement to eliminate malicious mailbox persistence.

Incorrect Answers

A:

Business email compromise can require financial recovery beyond technical mail control. That action would coordinate financial response to email fraud; it does not address the case's priority to eliminate malicious mailbox persistence.

B:

Evidence-led triage distinguishes malicious campaigns from harmless messages. It is primarily relevant when the need is to evaluate a reported suspicious email, rather than to eliminate malicious mailbox persistence.

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 eliminate malicious mailbox persistence.

Question 572

A security manager wants to isolate an entire region after one ambiguous alert with no evidence of spread. Which management response BEST addresses the stated risk or governance priority?

  1. Escalate to the designated incident command authority using approved BIA-based priorities.
  2. Evaluate evidence preservation and legal requirements before action when containment permits.
  3. Communicate confirmed containment status and unresolved risks through the approved spokesperson.
  4. Confirm scope and seek authorized proportionate containment based on credible risk.

Explanation

Correct Answer

D:

Broad disruptive action without evidence may create greater harm than the suspected threat. This directly meets the requirement to avoid unjustified enterprise-wide containment.

Incorrect Answers

A:

Enterprise governance resolves competing business claims through agreed impact criteria. That action would arbitrate shared-service crisis recovery priorities; it does not address the case's priority to avoid unjustified enterprise-wide containment.

B:

Incident decisions should protect legal interests without permitting uncontrolled damage. It is primarily relevant when the need is to reconcile evidence preservation with response decisions, rather than to avoid unjustified enterprise-wide containment.

C:

Crisis statements must avoid unsupported certainty while updating stakeholders. This would help report incident status honestly under pressure; the scenario instead requires a decision to avoid unjustified enterprise-wide containment.

Question 573

Two serious incidents compete for the same forensic specialists and both are escalating. Which management action BEST meets the stated requirement?

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

Explanation

Correct Answer

A:

Incident priorities should reflect enterprise consequence and urgency. This directly meets the requirement to prioritize competing incidents under resource pressure.

Incorrect Answers

B:

Sustainable response requires continuity of capable staff over extended operations. It is primarily relevant when the need is to sustain incident handling during a prolonged crisis, rather than to prioritize competing incidents under resource pressure.

C:

Shared cause and dependency warrant unified priorities and communication. This would help coordinate common-cause multi-unit incidents; the scenario instead requires a decision to prioritize competing incidents under resource pressure.

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 prioritize competing incidents under resource pressure.

Question 574

A company's cyber response plan assumes that restoring servers means customer fulfillment can resume instantly. Which decision is BEST supported by the business and security evidence?

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

Explanation

Correct Answer

B:

Business continuity addresses outcomes beyond infrastructure availability. This directly meets the requirement to bridge cyber recovery with business operating continuity.

Incorrect Answers

A:

Response needs channels independent of compromised production infrastructure. That action would maintain crisis command during communications failure; it does not address the case's priority to bridge cyber recovery with business operating continuity.

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 bridge cyber recovery with business operating continuity.

D:

Temporary continuity processes must preserve integrity and accountability. That action would ensure recovery from manual continuity operations; it does not address the case's priority to bridge cyber recovery with business operating continuity.

Question 575

An attacker modifies cloud audit retention during an incident. What is the MOST appropriate next action for the information security manager?

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

Explanation

Correct Answer

C:

Cloud audit evidence can be targeted to conceal attacker activity. This directly meets the requirement to protect cloud investigation evidence integrity.

Incorrect Answers

A:

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 protect cloud investigation evidence integrity.

B:

Cloud exposure investigations need context beyond a single public-permission flag. It is primarily relevant when the need is to investigate cloud data exposure cause, rather than to protect cloud investigation evidence integrity.

D:

Provider incidents can affect customer obligations and resilience even without direct configuration changes. That action would assess customer impact of cloud provider incidents; it does not address the case's priority to protect cloud investigation evidence integrity.

Question 576

A cleaned workstation remains infected because an attacker-controlled scheduled task is still present. Which management response BEST addresses the stated risk or governance priority?

  1. Revoke relevant sessions and tokens while resetting affected credentials.
  2. Correct the root vulnerability or configuration gap before reconnecting rebuilt systems.
  3. Identify all affected integration permissions and revoke unauthorized access enterprise-wide.
  4. Remove verified persistence mechanisms and validate with continued monitoring.

Explanation

Correct Answer

D:

Eradication must eliminate the source of reinfection, not only a detected payload. This directly meets the requirement to eradicate endpoint persistence.

Incorrect Answers

A:

Credential changes alone may not end existing authenticated attacker sessions. That action would eliminate persistent stolen-session access; it does not address the case's priority to eradicate endpoint persistence.

B:

Recovery without fixing the exploit path risks immediate recurrence. It is primarily relevant when the need is to remove initial access vulnerabilities before recovery, rather than to eradicate endpoint persistence.

C:

Persistence through shared integrations can survive local cleanup. This would help eradicate cross-application malicious integrations; the scenario instead requires a decision to eradicate endpoint persistence.

Question 577

A business owner wants immediate restoration of an infected server from an unverified snapshot. Which management action BEST meets the stated requirement?

  1. Validate snapshot integrity and clean recovery conditions before service reconnection.
  2. Verify protection and detection baselines before declaring the service fully restored.
  3. Reconcile data integrity and approved RPO before business acceptance.
  4. Require business-owner validation against acceptance and continuity criteria.

Explanation

Correct Answer

A:

Restoring compromised images can reintroduce the same threat. This directly meets the requirement to avoid reinfection through untrusted restoration.

Incorrect Answers

B:

Safe recovery includes necessary security controls, not only application availability. It is primarily relevant when the need is to restore security monitoring with the service, rather than to avoid reinfection through untrusted restoration.

C:

A running application is not recovered if required records are missing or corrupt. This would help validate transaction completeness after restoration; the scenario instead requires a decision to avoid reinfection through untrusted restoration.

D:

Recovery completion is a business outcome supported by technical testing. That action would obtain business acceptance of restored service; it does not address the case's priority to avoid reinfection through untrusted restoration.

Question 578

An incident report lists only technical malware indicators and omits major business disruption. Which decision is BEST supported by the business and security evidence?

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

Explanation

Correct Answer

B:

Lessons learned must address enterprise outcomes, not just malware artifacts. This directly meets the requirement to conduct an enterprise-focused post-incident review.

Incorrect Answers

A:

Lessons learned produce change only through accountable follow-through. That action would turn incident findings into corrective actions; it does not address the case's priority to conduct an enterprise-focused post-incident review.

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 conduct an enterprise-focused post-incident review.

D:

Learning does not require unrestricted disclosure of sensitive investigation material. That action would communicate lessons without overexposing evidence; it does not address the case's priority to conduct an enterprise-focused post-incident review.

Question 579

A privacy incident involves minors' records and ordinary breach playbooks ignore additional obligations. What is the MOST appropriate next action for the information security manager?

  1. Determine accessible data, exposure period and access evidence before final impact assessment.
  2. Provide authorized timely provisional reporting with uncertainty and follow-up commitments.
  3. Consult privacy and legal specialists and apply the applicable heightened notification rules.
  4. Route reporting determination to empowered legal, privacy and business leadership.

Explanation

Correct Answer

C:

Sensitive populations and data categories may alter duties and impact. This directly meets the requirement to account for special privacy breach obligations.

Incorrect Answers

A:

Exposure and confirmed extraction are different facts that affect reporting. That action would distinguish possible exposure from confirmed data access; it does not address the case's priority to account for special privacy breach obligations.

B:

Notification deadlines cannot always await complete investigation. It is primarily relevant when the need is to meet breach notice deadlines under uncertainty, rather than to account for special privacy breach obligations.

D:

Regulatory disclosures require informed authority beyond technical investigation. That action would assign proper privacy breach disclosure decisions; it does not address the case's priority to account for special privacy breach obligations.

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.
