CISA-KR 문제 236
다음 중 스프레드시트에서 핵심 재무 시스템으로 입력된 데이터를 검토할 때 감사인의 가장 큰 관심사는 무엇입니까?
정답: A
Explanation
The auditor's greatest concern when reviewing data inputs from spreadsheets into the core finance system would be undocumented code that formats data and transmits directly to the database. This is because undocumented code can introduce errors, inconsistencies, and security risks in the data processing and reporting. Undocumented code can also make it difficult to verify the accuracy, completeness, and validity of the data inputs and outputs, as well as to trace the source and destination of the data. Undocumented code can also violate the principles of segregation of duties, as the same person who creates the code may also have access to the data and the database.
The other options are not as concerning as undocumented code, although they may also pose some risks. A lack of complete inventory of spreadsheets and inconsistent file naming may make it challenging to identify and locate the relevant spreadsheets, but they do not directly affect the quality or integrity of the data inputs.
The department data protection policy not being reviewed or updated for two years may indicate a lack of awareness or compliance with the current data protection regulations, but it does not necessarily imply that the data inputs are compromised or inaccurate. Spreadsheets being accessible by all members of the finance department may increase the risk of unauthorized or accidental changes to the data, but it can be mitigated by implementing access controls, password protection, and audit trails.

CISA-KR 문제 237
재해 복구 계획(DRP)에는 다음 단계가 포함되어야 합니다.
정답: D
Explanation
A disaster recovery plan (DRP) is a set of detailed, documented guidelines that outline a business' critical assets and explain how the organization will respond to unplanned incidents. Unplanned incidents or disasters typically include cyberattacks, system failures, power outages, natural disasters, equipment failures, or infrastructure damage1. A DRP aims to minimize the impact of a disaster on the business continuity, data integrity, and service delivery of the organization. A DRP also helps the organization recover from a disaster as quickly and efficiently as possible.
A DRP should include steps for obtaining replacement supplies, as this is an essential part of restoring the normal operation of the organization after a disaster. Replacement supplies may include hardware, software, data, network components, office equipment, or other resources that are needed to resume the business functions and processes that were disrupted by the disaster. Obtaining replacement supplies may involve contacting vendors, suppliers, or partners; activating backup or alternative systems; or purchasing or renting new equipment. A DRP should identify the sources, locations, and costs of the replacement supplies, as well as the procedures and responsibilities for acquiring and installing them.
The other three options are not steps that a DRP should include, as they are either part of the pre-disaster planning process or not directly related to the disaster recovery objectives. Assessing and quantifying risk is a step that should be done before creating a DRP, as it helps identify the potential threats and vulnerabilities that could affect the organization and determine the likelihood and impact of each scenario2. Negotiating contracts with disaster planning consultants is also a pre-disaster activity that may help the organization design, implement, test, and maintain a DRP with external expertise and guidance3. Identifying application control requirements is not a step in a DRP, but rather a part of the application development and maintenance process that ensures the quality, security, and reliability of the software applications used by the organization.
Therefore, obtaining replacement supplies is the correct answer.

다음 중 포렌식 조사에서 증거를 가장 잘 보호하는 것은 무엇입니까?
정답: A
Explanation
Imaging the affected system is the best way to protect evidence in a forensic investigation, because it creates a bit-by-bit copy of the original data that can be analyzed without altering or compromising the original source. Imaging preserves the integrity and authenticity of the evidence and allows for verification and validation of the results34. Powering down or rebooting the affected system can cause data loss or corruption, while protecting the hardware does not prevent unauthorized access or tampering with the software or data.

다음 중 사내 기술 전문 인력이 없을 때 전자금융 솔루션 개발을 아웃소싱할 때의 가장 큰 장점은 무엇입니까?
정답: A
Explanation
Outsourcing the development of an e-banking solution when in-house technical expertise is not available can significantly reduce start-up costs. This is because the organization can avoid the expenses associated with hiring and training a full-time development team, purchasing necessary hardware and software, and maintaining the system1. While outsourcing can also potentially reduce the risk of system downtime, increase the ability to adapt the system, and provide direct oversight of risks, these benefits are not as immediate or guaranteed as the cost savings123.

조직의 소프트웨어 획득 프로세스를 감사할 때 IS 감사인이 조직에 대한 소프트웨어 이점을 이해하는 가장 좋은 방법은 다음을 검토하는 것입니다.
정답: B
Explanation
The best way for an IS auditor to understand the software benefits to the organization would be to review the business case, which is a document that provides the justification and rationale for acquiring a software solution based on its expected costs, benefits, risks, and alignment with the organization's goals and strategies.
The business case helps to evaluate the feasibility and viability of the software acquisition and to support the decision-making process. A feasibility study is a document that analyzes the technical, operational, economic, legal, and social aspects of a software solution to determine its feasibility and suitability for the organization's needs, but it does not necessarily provide a clear indication of the software benefits to the organization. A request for proposal (RFP) is a document that solicits proposals from potential vendors or suppliers for a software solution based on the organization's requirements and specifications, but it does not necessarily provide a clear indication of the software benefits to the organization. The alignment with IT strategy is a factor that influences the software acquisition process and ensures that the software solution supports and enables the organization's IT strategy, but it is not a document that can be reviewed by an IS auditor to understand the software benefits to the organization.
