CISA-KR 문제 1
거래 처리 시스템은 총계정원장과 인터페이스합니다. 데이터 분석 결과 일부 거래가 총계정원장에 두 번 기록되는 것으로 확인되었습니다. 경영진은 시스템 수정이 구현되었다고 말하지만, 인터페이스가 향후 작동하는지 확인하기 위해 IS 감사인은 무엇을 권장해야 합니까?
정답: A
Explanation
A transaction processing system (TPS) is a system that captures, processes, and stores data related to business transactions1. A general ledger is a system that records the financial transactions of an organization in different accounts2. An interface is a connection point between two systems that allows data exchange3. A system fix is a change or update to a system that resolves a problem or improves its functionality4.
The IS auditor should recommend to perform periodic reconciliations to validate the interface between the TPS and the general ledger is working in the future. A reconciliation is a process of comparing and verifying the data in two systems to ensure accuracy and consistency1. By performing periodic reconciliations, the IS auditor can detect and correct any errors or discrepancies in the data, such as duplicate transactions, missing transactions, or incorrect amounts. This way, the IS auditor can ensure the reliability and integrity of the financial data in both systems.
The other options are not as effective as periodic reconciliations to validate the interface. System owner sign-off for the system fix is a form of approval that indicates the system owner agrees with the change and its expected outcome4. However, this does not guarantee that the system fix will work as intended or prevent future errors. Conducting functional testing is a process of verifying that the system performs its intended functions correctly and meets its requirements4. However, this is usually done before or after the system fix is implemented, not on an ongoing basis. Improving user acceptance testing (UAT) is a process of evaluating whether the system meets the needs and expectations of the end users4. However, this is also done before or after the system fix is implemented, not on an ongoing basis. Therefore, option A is the correct answer.

CISA-KR 문제 2
소프트웨어 개발의 폭포수 라이프 사이클 모델은 다음 중 어떤 상황에 가장 적합합니까?
정답: A
Explanation
The waterfall life cycle model of software development is best suited for situations where the project requirements are well understood. The waterfall life cycle model is a sequential and linear approach to software development that consists of several phases, such as planning, analysis, design, implementation, testing, and maintenance. Each phase depends on the completion and approval of the previous phase before proceeding to the next phase. The waterfall life cycle model is best suited for situations where the project requirements are well understood, as it assumes that the requirements are clear, stable, and fixed at the beginning of the project, and do not change significantly throughout the project. The project is subject to time pressures is not a situation where the waterfall life cycle model of software development is best suited, as it may not be flexible or agile enough to accommodate changes or adjustments in the project schedule or timeline. The waterfall life cycle model may involve long delays or dependencies between phases, and may not allow for early feedback or delivery of software products. The project intends to apply an object-oriented design approach is not a situation where the waterfall life cycle model of software development is best suited, as it may not be compatible or effective with the object-oriented design approach. The object-oriented design approach is a technique that models software as a collection of interacting objects that have attributes and behaviors. The object-oriented design approach may require iterative and incremental development methods that allow for dynamic and adaptive changes in software design and functionality. The project will involve the use of new technology is not a situation where the waterfall life cycle model of software development is best suited, as it may not be able to cope with the uncertainty or complexity of new technology. The waterfall life cycle model may not allow for sufficient exploration or experimentation with new technology, and may not be able to handle changes or issues that arise from new technology.

중요한 비즈니스 프로세스를 실행하는 라이선스 소프트웨어에 대한 계약을 검토하는 IS 감사인의 가장 큰 우려 사항은 무엇입니까?
정답: D
Explanation
The greatest concern for an IS auditor reviewing contracts for licensed software that executes a critical business process is that software escrow was not negotiated. Software escrow is an arrangement where a third-party holds a copy of the source code and documentation of a licensed software in a secure location. The software escrow agreement specifies the conditions under which the licensee can access the escrowed materials, such as in case of bankruptcy, termination, or breach of contract by the licensor. Software escrow is important for ensuring the continuity and availability of a critical business process that depends on a licensed software. Without software escrow, the licensee may face significant risks and challenges in maintaining, modifying, or recovering the software in case of any disruption or dispute with the licensor.

새로운 규정에 따르면 조직은 중대한 보안 사고를 식별한 후 24시간 이내에 규제 기관에 보고해야 합니다. 다음 중 규정 준수를 촉진하기 위한 IS 감사인의 가장 좋은 권장 사항은 무엇입니까?
정답: A
Explanation
The best recommendation to facilitate compliance with the regulation that requires organizations to report significant security incidents to the regulator within 24 hours of identification is to include the requirement in the incident management response plan. An incident management response plan is a document that defines the roles, responsibilities, procedures, and tools for managing security incidents effectively and efficiently.
Including the requirement in the incident management response plan can help ensure that security incidents are identified, classified, reported, and escalated in accordance with the regulation. The other options are not as effective as including the requirement in the incident management response plan, as they do not address all aspects of incident management or compliance. Establishing key performance indicators (KPIs) for timely identification of security incidents is a monitoring technique that can help measure and improve the performance of incident management processes, but it does not ensure compliance with the regulation.
Enhancing the alert functionality of the intrusion detection system (IDS) is a technical control that can help detect and notify security incidents faster, but it does not ensure compliance with the regulation. Engaging an external security incident response expert for incident handling is a contingency measure that can help augment the organization's internal capabilities and resources for managing security incidents, but it does not ensure compliance with the regulation.

IT 직원 개발 계획과 IT 전략을 일치시키려면 다음 중 무엇을 가장 먼저 수행해야 합니까?
정답: C
Explanation
Identifying required IT skill sets that support key business processes is the first step to enable the alignment of IT staff development plans with IT strategy. An IT strategy is a plan that defines how IT will support the organization's goals and objectives. Identifying required IT skill sets means determining the knowledge, abilities, and competencies that IT staff need to perform their roles and responsibilities effectively and efficiently. This can help to align IT staff development plans with IT strategy, as well as to identify and address any skill gaps or needs within the IT workforce. The other options are not the first steps to enable alignment, but rather possible subsequent actions that may depend on the required IT skill sets. References:
