CISA-KR 문제 346
IS 감사원은 사업 비용 청구 시스템 내에서 사기를 방지하는 프로세스를 검토하라는 임무를 받았습니다. 다음 이해 관계자 중 이 검토에 가장 중요한 것은 무엇입니까?
정답: D
The business process owner is the most important stakeholder to involve in the review of the processes that prevent fraud within a business expense claim system. This is because the business process owner is responsible for defining, implementing, and monitoring the business rules and policies that govern the expense claim process. The business process owner also has the authority and accountability to approve or reject expense claims, as well as to investigate and report any suspicious or fraudulent activities. The business process owner can provide valuable insights and feedback to the IS auditor on the effectiveness and efficiency of the current processes, aswell as the potential risks and controls that need to be addressed12.
The information security manager is not the most important stakeholder because their role is mainly focused on ensuring the confidentiality, integrity, and availability of the information systems and data that support the expense claim process. The information security manager can help the IS auditor with assessing the technical aspects of the system, such as access controls, encryption, logging, and backup, but they may not have sufficient knowledge or authority over the business rules and policies that prevent fraud1.
The quality assurance (QA) manager is not the most important stakeholder because their role is mainly focused on ensuring the quality and reliability of the software applications and systems that support the expense claim process. The QA manager can help the IS auditor with testing and verifying the functionality and performanceof the system, but they may not have sufficient knowledge or authority over the business rules and policies that prevent fraud1.
The business department executive is not the most important stakeholder because their role is mainly focused on overseeing the strategic objectives and financial performance of the business department that uses the expense claim system. The business department executive can help the IS auditor with understanding the business context and needs of the expense claim process, but they may not have sufficient knowledge or authority over the operational details and controls that prevent fraud

CISA-KR 문제 347
사내에서 시스템을 개발하는 것과 비교했을 때, 소프트웨어 패키지를 구매하는 것은 최종 사용자가 테스트해야 할 필요성이 있다는 것을 의미합니다.
정답: B
Compared to developing a system in-house, acquiring a software package means that the need for testing by end users is unchanged. This is because end users are still the ultimate customers and beneficiaries of the system, and they need to ensure that the software package meets their requirements, expectations, and satisfaction. End user testing, also known as user acceptance testing (UAT) or beta testing, is the final stage of testing performed by the user or client to determine whether the software can be accepted or not1. End user testing is important for both in-house developed and acquired software packages, as it helps to verify the functionality, usability, performance, and reliability of the system2. End user testing also helps to identify and resolve any defects, errors, or issues that may not have been detected by the developers or vendors3.
Therefore, option B is the correct answer.
Option A is not correct because end user testing is not eliminated by acquiring a software package. Even though the software package may have been tested by the vendor or supplier, it may still have bugs, compatibility issues, or configuration problems that need to be fixed before deployment4. Option C is not correct because end user testing is not increased by acquiring a software package. The scope and extent of end user testing depend on various factors, such as the complexity, criticality, and customization of the system, and not on whether it is developed in-house or acquired. Option D is not correct because end user testing is not reduced by acquiring a software package. The software package may still require modifications or integrations to suit the specific needs and environment of the organization, and these changes need to be tested by the end users.

CISA-KR 문제 348
데이터 캔터의 인후 평가를 검토하는 IS 감사원은 다음과 같은 경우 가장 우려할 것입니다.
정답: B
An IS auditor reviewing the threat assessment for a data center would be most concerned if all identified threats relate to external entities. This indicates that the threat assessment is incomplete and biased, as it ignores the potential threats from internal sources, such as employees, contractors, vendors, or authorized visitors. Internal threats can pose significant risks to the data center, as they may have access to sensitive information, systems, or facilities, and may exploit their privileges for malicious or fraudulent purposes. According to a study by IBM, 60% of cyberattacks in 2015 were carried out by insiders1 Some of the identified threats are unlikely to occur is not a cause for concern, as it shows that the threat assessment is comprehensive and realistic, and considers all possible scenarios, regardless of their probability.
A threat assessment should not exclude any potential threats based on subjective judgments or assumptions, as they may still have a high impact if they materialize.
The exercise was completed by local management is not a cause for concern, as it shows that the threat assessment is conducted by the people who are most familiar with the data center's operations, environment, and risks. Local management may have more relevant and accurate information and insights than external parties, and may be more invested in the outcome of the threat assessment.
Neighboring organizations' operations have been included is not a cause for concern, as it shows that the threat assessment is holistic and contextual, and considers the interdependencies and influences of external factors on the data center's security. Neighboring organizations' operations may pose direct or indirect threats to the data center, such as physical damage, network interference, or shared vulnerabilities.

조직은 타사 서비스 제공업체로부터 자동화된 데이터 피드를 엔터프라이즈 데이터 웨어하우스로 수신할 계획입니다. 다음 중 잘못된 데이터 수신을 방지하는 가장 좋은 방법은 무엇일까요?
정답: D
The best way to prevent accepting bad data from a third-party service provider is to implement business rules to reject invalid data. Business rules are logical statements that define the data quality requirements and standards for the organization. By implementing business rules, the organization can ensure that only data that meets the predefined criteria is accepted into the enterprise data warehouse. Obtaining error codes indicating failed data feeds, purchasing data cleansing tools from a reputable vendor, and appointing data quality champions across the organization are useful measures to improve data quality, but they do not prevent accepting bad data in the first place.

한 조직이 최근 고객에게 대출을 제공하기 위한 지능형 에이전트 소프트웨어를 인수하여 구현했습니다. 구현 후 검토 중에 IS 감사자가 수행해야 하는 가장 중요한 절차는 다음 중 어느 것입니까?
정답: B
Reviewing input and output control reports to verify the accuracy of the system decisions is the most important procedure for the IS auditor to perform during the post-implementation review of intelligent-agent software for granting loans to customers, because it can help identify any errors or anomalies in the system logic or data that may affect the quality and reliability of the system outcomes. Reviewing system and error logs, signed approvals, and system documentation are also important procedures, but they are not as critical as verifying the accuracy of the system decisions.
