Question 570

Management reports that this issue has been corrected: A cloud move assumes existing encryption keys will work in the target without import or custody testing. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. A migrated encrypted sample is accessible to authorized users and remains protected.
  2. Target balances, exceptions and sampled loan histories reconcile to source records.
  3. Invalid or manipulated requests are blocked and legitimate transactions remain correct.
  4. Sample and aggregate source-to-target totals agree or documented exceptions are resolved.

Explanation

Correct Answer

A:

A migrated encrypted sample is accessible to authorized users and remains protected. It addresses system migration, infrastructure deployment, and data conversion. Underlying audit concern: Migration design must preserve cryptographic dependencies and data accessibility.

Incorrect Answers

B:

Target balances, exceptions and sampled loan histories reconcile to source records. This would be relevant to a different issue such as: A bank converts 20 years of loan records into a new core system and reconciles only total record counts. In the present case, the most directly relevant verification is: A migrated encrypted sample is accessible to authorized users and remains protected. The governing distinction is: Migration design must preserve cryptographic dependencies and data accessibility.

C:

Invalid or manipulated requests are blocked and legitimate transactions remain correct. This would be relevant to a different issue such as: A payment API relies on user-supplied transaction values without server-side validation. In the present case, the most directly relevant verification is: A migrated encrypted sample is accessible to authorized users and remains protected. The governing distinction is: Migration design must preserve cryptographic dependencies and data accessibility.

D:

Sample and aggregate source-to-target totals agree or documented exceptions are resolved. This would be relevant to a different issue such as: A data migration design encrypts transfers but does not detect missing or duplicated customer records. In the present case, the most directly relevant verification is: A migrated encrypted sample is accessible to authorized users and remains protected. The governing distinction is: Migration design must preserve cryptographic dependencies and data accessibility.

Question 571

An IS auditor evaluates this situation: An inventory API responds successfully while silently truncating long product descriptions during integration. Which audit principle MOST directly applies to this situation?

  1. Emergency changes need accelerated but documented authorization and retrospective review.
  2. Interfaces need defined data ownership and conflict-resolution rules.
  3. Interface testing must verify semantic accuracy and completeness, not only transport success.
  4. Business impact includes legal, safety, customer and operational harm beyond revenue.

Explanation

Correct Answer

C:

Interface testing must verify semantic accuracy and completeness, not only transport success. The corresponding audit procedure is: Compare schema limits, payload samples, rejected records and target field mapping.

Incorrect Answers

A:

Emergency changes need accelerated but documented authorization and retrospective review. This would be relevant to a different issue such as: An urgent firewall change is deployed without a ticket and later cannot be attributed to an approver. In the present case, the most directly relevant principle is: Interface testing must verify semantic accuracy and completeness, not only transport success. The governing distinction is: Interface testing must verify semantic accuracy and completeness, not only transport success.

B:

Interfaces need defined data ownership and conflict-resolution rules. This would be relevant to a different issue such as: Two systems independently update the same customer address, producing unpredictable last-write results. In the present case, the most directly relevant principle is: Interface testing must verify semantic accuracy and completeness, not only transport success. The governing distinction is: Interface testing must verify semantic accuracy and completeness, not only transport success.

D:

Business impact includes legal, safety, customer and operational harm beyond revenue. This would be relevant to a different issue such as: Continuity leadership bases recovery priorities on annual revenue only and ignores safety-critical low-volume services. In the present case, the most directly relevant principle is: Interface testing must verify semantic accuracy and completeness, not only transport success. The governing distinction is: Interface testing must verify semantic accuracy and completeness, not only transport success.

Question 572

An IS auditor evaluates this situation: A data migration design encrypts transfers but does not detect missing or duplicated customer records. Which audit principle MOST directly applies to this situation?

  1. Confidentiality does not replace integrity and completeness controls for converted data.
  2. Control requirements should be identified from business risk during system design.
  3. An iterative development method still requires risks and controls within its delivery process.
  4. Effective oversight requires consolidated delivery reporting and objective milestone evidence.

Explanation

Correct Answer

A:

Confidentiality does not replace integrity and completeness controls for converted data. The corresponding audit procedure is: Review reconciliation strategy, source/target counts, control totals and exception paths.

Incorrect Answers

B:

Control requirements should be identified from business risk during system design. This would be relevant to a different issue such as: A new web checkout design addresses user experience but fails to define controls for unauthorized refund changes. In the present case, the most directly relevant principle is: Confidentiality does not replace integrity and completeness controls for converted data. The governing distinction is: Confidentiality does not replace integrity and completeness controls for converted data.

C:

An iterative development method still requires risks and controls within its delivery process. This would be relevant to a different issue such as: An agile team delivers features every sprint but security stories are never included in the product backlog. In the present case, the most directly relevant principle is: Confidentiality does not replace integrity and completeness controls for converted data. The governing distinction is: Confidentiality does not replace integrity and completeness controls for converted data.

D:

Effective oversight requires consolidated delivery reporting and objective milestone evidence. This would be relevant to a different issue such as: A program steering committee receives status reports from one vendor but has no visibility into independent testing delays. In the present case, the most directly relevant principle is: Confidentiality does not replace integrity and completeness controls for converted data. The governing distinction is: Confidentiality does not replace integrity and completeness controls for converted data.

Question 573

An IS auditor is preparing recommendations after reviewing this situation: Privileged database administrators routinely use shared root credentials without individual attribution. Which recommendation would BEST address the identified weakness?

  1. Recommend named privileged access with controlled elevation and session accountability.
  2. Recommend restricted emergency access with independent after-use review and periodic exercises.
  3. Recommend least-privilege template controls and automated exposure monitoring.
  4. Recommend role-based training prerequisites and tracked renewal for external users.

Explanation

Correct Answer

A:

Recommend named privileged access with controlled elevation and session accountability. The relevant control principle is: Privileged access should be individually attributable and constrained by least privilege. A meaningful follow-up should establish: Privileged actions map to authorized identities and shared credential use is restricted.

Incorrect Answers

B:

Recommend restricted emergency access with independent after-use review and periodic exercises. This would be relevant to a different issue such as: Emergency administrator accounts are exempt from monitoring and are never tested until an outage. In the present case, the most directly relevant recommendation is: Recommend named privileged access with controlled elevation and session accountability. The governing distinction is: Privileged access should be individually attributable and constrained by least privilege.

C:

Recommend least-privilege template controls and automated exposure monitoring. This would be relevant to a different issue such as: A cloud storage bucket used for personnel data becomes publicly readable after a template change. In the present case, the most directly relevant recommendation is: Recommend named privileged access with controlled elevation and session accountability. The governing distinction is: Privileged access should be individually attributable and constrained by least privilege.

D:

Recommend role-based training prerequisites and tracked renewal for external users.

The governing distinction is: Privileged access should be individually attributable and constrained by least privilege.

Question 574

An IS auditor is preparing recommendations after reviewing this situation: A production release changes database permissions manually after the reviewed deployment package was approved. Which recommendation would BEST address the identified weakness?

  1. Recommend preventive entitlement checks and independent monitoring in design acceptance criteria.
  2. Recommend a controlled recovery exercise or documented risk acceptance before launch.
  3. Recommend a proportionate emergency gate with tested rollback and follow-up review.
  4. Recommend approved configuration-as-code or logged emergency change control.

Explanation

Correct Answer

D:

Recommend approved configuration-as-code or logged emergency change control. The relevant control principle is: Configuration changes must remain controlled, traceable and aligned with approved baselines. A meaningful follow-up should establish: Production permissions match reviewed baselines and exceptions have documented approval.

Incorrect Answers

A:

Recommend preventive entitlement checks and independent monitoring in design acceptance criteria. This would be relevant to a different issue such as: A new web checkout design addresses user experience but fails to define controls for unauthorized refund changes. In the present case, the most directly relevant recommendation is: Recommend approved configuration-as-code or logged emergency change control. The governing distinction is: Configuration changes must remain controlled, traceable and aligned with approved baselines.

B:

Recommend a controlled recovery exercise or documented risk acceptance before launch. This would be relevant to a different issue such as: A new inventory system's disaster-recovery test is deferred because normal transaction testing passes. In the present case, the most directly relevant recommendation is: Recommend approved configuration-as-code or logged emergency change control. The governing distinction is: Configuration changes must remain controlled, traceable and aligned with approved baselines.

C:

Recommend a proportionate emergency gate with tested rollback and follow-up review. This would be relevant to a different issue such as: An emergency patch goes live without a rollback plan or verification of required interfaces. In the present case, the most directly relevant recommendation is: Recommend approved configuration-as-code or logged emergency change control. The governing distinction is: Configuration changes must remain controlled, traceable and aligned with approved baselines.

Question 575

Management reports that this issue has been corrected: A chief technology officer both accepts enterprise cyber risk and certifies the independence of the risk oversight function. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Reopened incident and false-closure rates are tracked and reduced.
  2. Expired exceptions close or are explicitly renewed with current evidence and risk ownership.
  3. IT performance reports demonstrate progress toward business-approved goals.
  4. Approvals show authorized risk owners and recorded independent challenge for material exposures.

Explanation

Correct Answer

D:

Approvals show authorized risk owners and recorded independent challenge for material exposures. It addresses organizational structure, it governance, and it strategy. Underlying audit concern: Governance should define risk ownership and objective challenge across accountable roles.

Incorrect Answers

A:

Reopened incident and false-closure rates are tracked and reduced. This would be relevant to a different issue such as: A shared IT helpdesk closes incidents quickly by marking unresolved requests as user error. In the present case, the most directly relevant verification is: Approvals show authorized risk owners and recorded independent challenge for material exposures. The governing distinction is: Governance should define risk ownership and objective challenge across accountable roles.

B:

Expired exceptions close or are explicitly renewed with current evidence and risk ownership. This would be relevant to a different issue such as: A vendor incident triggers a temporary exception but the residual risk is never reconsidered after six months. In the present case, the most directly relevant verification is: Approvals show authorized risk owners and recorded independent challenge for material exposures. The governing distinction is: Governance should define risk ownership and objective challenge across accountable roles.

C:

IT performance reports demonstrate progress toward business-approved goals. This would be relevant to a different issue such as: An IT strategy document lists new tools but has no targets for customer availability or service costs. In the present case, the most directly relevant verification is: Approvals show authorized risk owners and recorded independent challenge for material exposures. The governing distinction is: Governance should define risk ownership and objective challenge across accountable roles.

Question 576

Before reaching an audit conclusion, consider: Contractor onboarding omits data-handling training although contractors access classified research files. Which evidence should the auditor review FIRST to evaluate this risk?

  1. Compare contractor rosters, entitlements, training records and onboarding gates.
  2. Assess current threat activity, service dependencies and available containment alternatives.
  3. Compare simulation outcomes, repeat behavior, reporting rates and learner groups.
  4. Review access routes, door alarms, visitor logs and response procedures.

Explanation

Correct Answer

A:

Compare contractor rosters, entitlements, training records and onboarding gates. The governing principle is: Awareness programs must reach all relevant roles before sensitive access is granted.

Incorrect Answers

B:

In the present case, the most directly relevant verification is: The engagement record shows independent decisions and an appropriately handled ethics disclosure. The governing distinction is: Perceived or actual conflicts undermine the credibility of objective audit judgment.

Question 579

An IS auditor evaluates this situation: A sales system's backup schedule is chosen before the business determines acceptable data loss. Which audit principle MOST directly applies to this situation?

  1. Business impact includes legal, safety, customer and operational harm beyond revenue.
  2. RPO should be derived from business impact and transactional tolerance, not backup convenience.
  3. Availability analysis must include upstream shared dependencies, not just redundant hosts.
  4. Infrastructure component changes require compatibility and interface impact assessment.

Explanation

Correct Answer

B:

RPO should be derived from business impact and transactional tolerance, not backup convenience. The corresponding audit procedure is: Quantify financial and operational consequences of lost transactions over time.

Incorrect Answers

A:

Business impact includes legal, safety, customer and operational harm beyond revenue. This would be relevant to a different issue such as: Continuity leadership bases recovery priorities on annual revenue only and ignores safety-critical low-volume services. In the present case, the most directly relevant principle is: RPO should be derived from business impact and transactional tolerance, not backup convenience. The governing distinction is: RPO should be derived from business impact and transactional tolerance, not backup convenience.

C:

Availability analysis must include upstream shared dependencies, not just redundant hosts. This would be relevant to a different issue such as: A redundant web cluster shares one DNS resolver and becomes inaccessible when that resolver fails. In the present case, the most directly relevant principle is: RPO should be derived from business impact and transactional tolerance, not backup convenience. The governing distinction is: RPO should be derived from business impact and transactional tolerance, not backup convenience.

D:

Infrastructure component changes require compatibility and interface impact assessment. This would be relevant to a different issue such as: A network router is upgraded without identifying the legacy protocol needed by an older warehouse controller. In the present case, the most directly relevant principle is: RPO should be derived from business impact and transactional tolerance, not backup convenience.
