CISA-KR 문제 127
사용자들은 새로 출시된 ERP(Enterprise Resource Planning) 시스템이 너무 느리게 작동한다고 불평하고 있습니다. 품질 보증(QA) 단계 중 다음 중 어떤 테스트가 이 문제를 식별했을까요?
정답: A
Stress testing is a type of performance testing that evaluates how a system behaves under extreme load conditions, such as high user traffic, large data volumes, or limited resources. It is useful for identifying potential bottlenecks, errors, or failures that may affect the system's functionality or availability. Stress testing during the quality assurance (QA) phase would have identified the concern of users complaining that a newly released ERP system is functioning too slowly. The other options are not as relevant for this concern, as they relate to different aspects of testing, such as regression testing (verifying that existing functionality is not affected by new changes), interface testing (verifying that the system interacts correctly with other systems or components), or integration testing (verifying that the system works as a whole after combining different modules or units).

CISA-KR 문제 128
IS 감사원은 애플리케이션 서버의 보안 설정이 일관되지 않아 잠재적인 취약성이 발생했다는 것을 발견했습니다. IS 감사원의 가장 좋은 권장 사항은 다음 중 어느 것입니까?
정답: D
The best recommendation by the IS auditor for finding that application servers had inconsistent security settings leading to potential vulnerabilities is to perform a configuration review. A configuration review is an audit procedure that involves examining and verifying the security settings and parameters of application servers against predefined standards or best practices. A configuration review can help to identify and remediate any deviations, inconsistencies, or misconfigurations thatmay expose the application servers to unauthorized access, exploitation, or compromise6. A configuration review can also help to ensure compliance with security policies and regulations, as well as enhance the performance and availability of application servers. The other options are less effective or incorrect because:
* A. Improving the change management process is not the best recommendation by the IS auditor for finding that application servers had inconsistent security settings leading to potential vulnerabilities, as it does not address the root cause of the problem or provide a specific solution. While improving the change management process may help to prevent future inconsistencies or misconfigurations in application server settings, it does not ensure that the existing ones are detected and corrected.
* B. Establishing security metrics is not the best recommendation by the IS auditor for finding that application servers had inconsistent security settings leading to potential vulnerabilities, as it does not address the root cause of the problem or provide a specific solution. While establishing security metrics may help to measure and monitor the security performance and posture of application servers, it does not ensure that the existing inconsistencies or misconfigurations in application server settings are detected and corrected.
* C. Performing a penetration test is not the best recommendation by the IS auditor for finding that application servers had inconsistent security settings leading to potential vulnerabilities, as it does not address the root cause of the problem or provide a specific solution. While performing a penetration test may help to simulate and evaluate the impact of an attack on application servers, it does not ensure that the existing inconsistencies or misconfigurations in application server settings are detected and corrected.

CISA-KR 문제 129
IS 감사 관리자가 조직의 급여 애플리케이션 업그레이드에 배정된 프로젝트 관리자를 감독하는 업무를 일시적으로 맡았습니다. 감사 부서로 복귀한 감사 관리자는 급여 애플리케이션 구현을 검증하기 위해 감사를 수행하라는 요청을 받았습니다. 감사 관리자는 감사 부서에서 IT 프로젝트 관리 경험이 있는 유일한 사람입니다. 가장 좋은 조치 방침은 무엇입니까?
정답: B
Outsourcing the audit to independent and qualified resources is the best course of action for the IS audit manager who was temporarily tasked with supervising a project manager assigned to the organization's payroll application upgrade. This is because the IS audit manager has a potential conflict of interest and a threat to objectivity and independence, which are essential principles and standards for IS auditors.
According to the ISACA Code of Professional Ethics, IS auditors should maintain objectivity and independence in their professional judgment and avoid any situations that may impair or be presumed to impair their objectivity or independence1. Objectivity is the mental attitude of an IS auditor that allows them to perform their work honestly, impartially, and with integrity, while independence is the freedom from conditions that threaten the ability of an IS auditor to carry out their work in an unbiased manner2.
The IS audit manager who was involved in supervising the payroll application upgrade project may have a self-review threat, which is the risk that an IS auditor will not appropriately evaluate the results of a previous judgment made or service performed by them or their subordinates3. The IS audit manager may also have a familiarity threat, which is the risk that an IS auditor will be influenced by a close relationship with someone involved in the project or by their own personal interests4. These threats may compromise the IS audit manager's objectivity and independence and affect the quality and credibility of the audit.
Therefore, the IS audit manager should disclose their involvement in the project to their senior management and the audit committee and decline to perform or manage the audit. The IS audit manager should also recommend outsourcing the audit to independent and qualified resources who have no connection or interest in the project and who have the necessary skills and experience to conduct a reliable and effective audit.
The other options are not the best course of action for the IS audit manager.
Transferring the assignment to a different audit manager despite lack of IT project management experience is not the best course of action because it may result in a low-quality audit that does not meet the expectations and standards of the stakeholders. IT project management experience is essential for auditing an IT project, as it requires knowledge of project management methodologies, tools, techniques, risks, and best practices. An audit manager who lacks IT project management experience may not be able to plan, execute, report, and follow up on the audit effectively and efficiently.
Managing the audit since there is no one else with the appropriate experience is not the best course of action because it violates the ethical principles and standards of objectivity and independence for IS auditors.
Managing the audit would create a conflict of interest and a threat to objectivity and independence for the IS audit manager, as they would be reviewing their own work or that of their subordinate. Managing the audit would also undermine the credibility and reliability of the audit results and recommendations, as they may be biased or influenced by personal or professional relationships or interests.
Having a senior IS auditor manage the project with the IS audit manager performing final review is not the best course of action because it still involves the IS audit manager in the audit process, which poses a conflict of interest and a threat to objectivity and independence. Performing final review would require the IS audit manager to evaluate and approve the work done by the senior IS auditor, which may be affected by their previous involvement in or knowledge of the project. Performing final review would also expose theIS audit manager to undue pressure or influence from management or other stakeholders who may have expectations or preferences regarding the audit outcome.

클라우드 기반 시스템의 애플리케이션 통제를 평가하기 위한 감사를 계획할 때 IS 감사자가 가장 중요하게 생각하는 것은 다음과 같습니다.
정답: B
The business process supported by the system is the most important factor for an IS auditor to understand when planning an audit to assess application controls of a cloud-based system. An IS auditor should have a clear understanding of the business objectives, requirements, and risks of the process, as well as the expected outputs and outcomes of the system. This will help the IS auditor to determine the scope, objectives, and criteria of the audit, as well as to identify and evaluate the key application controls that ensure the effectiveness, efficiency, and reliability of the process. The other options are less important factors that may provide additional information or context for the audit, but not its primary focus. References:
