CISA-KR 문제 256
조직은 최근에 클라우드 문서 저장 솔루션을 구현하고 최종 사용자가 로컬 워크스테이션 하드 드라이브에 데이터를 저장할 수 있는 기능을 제거했습니다. 다음 중 IS 감사인이 가장 우려해야 할 사항은 무엇입니까?
정답: C
Explanation
This should be the IS auditor's greatest concern, because it means that the organization has not considered the potential impact of the cloud document storage solution on its ability to continue its operations in the event of a disruption or disaster. A BCP is a document that outlines the procedures and actions to be taken in order to maintain or resume critical business functions during and after a crisis. A BCP should be updated whenever there is a significant change in the organization's IT infrastructure, systems, processes, or dependencies, such as implementing a cloud document storage solution. The IS auditor should verify that the BCP reflects the current state of the organization's IT environment, and that it addresses the risks, challenges, and opportunities associated with the cloud document storage solution.
The other options are not as concerning as the BCP not being updated:
Users are not required to sign updated acceptable use agreements. This is a minor concern, but it does not pose a major threat to the organization's business continuity. Acceptable use agreements are documents that define the rules and guidelines for using IT resources, such as the cloud document storage solution. Users should sign updated acceptable use agreements to acknowledge their responsibilities and obligations, and to comply with the organization's policies and standards. However, this does not affect the organization's ability to continue its operations in a crisis.
Users have not been trained on the new system. This is a moderate concern, but it does not jeopardize the organization's business continuity. Training users on the new system is important to ensure that they can use it effectively and efficiently, and to avoid errors or misuse that could compromise the security or performance of the system. However, this does not prevent the organization from accessing or restoring its data in a crisis.
Mobile devices are not encrypted. This is a serious concern, but it does not directly impact the organization's business continuity. Encrypting mobile devices is a security measure that protects the data stored on them from unauthorized access or disclosure in case of loss or theft. However, this does not affect the availability or integrity of the data stored in the cloud document storage solution, which should have its own encryption mechanisms.

CISA-KR 문제 257
감사 보고서 초안을 논의하는 동안 IT 관리자는 IS 감사인이 효과가 없다고 결론을 내린 컨트롤에 대해 프로세스가 구현되었다는 적절한 증거를 제공했습니다. 다음 중 감사인의 최선의 조치는 무엇입니까?
정답: D
Explanation
The auditor's best action is to re-perform the audit before changing the conclusion, because the auditor needs to obtain sufficient and appropriate evidence to support the audit opinion. The evidence provided by IT management may not be reliable or relevant, and it may not reflect the actual effectiveness of the control during the audit period. Therefore, the auditor should verify the evidence independently and test the control again to ensure that it meets the audit criteria and objectives. The other options are not appropriate, because they either ignore or accept the evidence provided by IT management without verification, which may compromise the quality and integrity of the audit.

경영진은 새로운 IT 시스템의 구현이 제 시간에 완료되지 않을 것임을 알고 감사를 요청했습니다. 다음 감사 결과 중 가장 우려해야 할 사항은 무엇입니까?
정답: B
Explanation
The audit finding that should be of greatest concern is that tasks defined on the critical path do not have resources allocated, as this means that the project is likely to face significant delays and cost overruns, since the critical path is the sequence of activities that determines the minimum time required to complete the project. The actual start times of some activities being later than originally scheduled may indicate some minor deviations from the project plan, but they may not necessarily affect the overall project completion time if they are not on the critical path. The project manager lacking formal certification may affect the quality and efficiency of the project management process, but it does not necessarily imply that the project manager is incompetent or unqualified. Milestones have been defined for all project products, but they may not be realistic or achievable if they do not take into account the resource constraints and dependencies of the critical path tasks.

CISA-KR 문제 259
다음 중 조직이 최근에 구현한 BYOD(Bring Your Own Device) 전략과 관련된 보안 위험을 해결하는 데 가장 도움이 되는 것은 무엇입니까?
정답: D
Explanation
A mobile device awareness program would best enable an organization to address the security risks associated with a recently implemented bring your own device (BYOD) strategy. A mobile device awareness program is a set of activities that aim to educate and inform the employees about the benefits, challenges, and best practices of using their personal mobile devices for work purposes. A mobile device awareness program can help the organization to:
Communicate the organization's policies and expectations regarding BYOD, such as which devices are allowed, what data can be accessed or stored, and what security measures are required.
Raise the employees' awareness of the potential threats and vulnerabilities that affect their mobile devices, such as malware, phishing, data leakage, or device loss.
Provide the employees with guidance and tips on how to protect their mobile devices and the organization's data, such as using strong passwords, encryption, antivirus software, remote wipe, or VPN.
Encourage the employees to report any incidents or issues related to their mobile devices, such as suspicious messages, unauthorized access, or device damage.
A mobile device awareness program can help the organization to reduce the security risks associated with BYOD by enhancing the employees' knowledge, skills, and behavior in using their mobile devices securely and responsibly. A mobile device awareness program can also help the organization to comply with relevant regulations and standards that govern data privacy and security in the cloud1.
The other options are not as effective as a mobile device awareness program in enabling an organization to address the security risks associated with BYOD. Option A, mobile device tracking program, is a tool that allows the organization to monitor and locate the employees' mobile devices in case of loss or theft. However, this tool may not prevent or detect other types of security risks, such as malware infection or data breach.
Option B, mobile device upgrade program, is a process that ensures that the employees' mobile devices are running the latest versions of operating systems and applications. However, this process may not address other aspects of security, such as user behavior or data protection. Option C, mobile device testing program, is a method that verifies the functionality and compatibility of the employees' mobile devices with the organization's systems and networks. However, this method may not cover all the scenarios or factors that may affect the security of the mobile devices or the organization's data2.

다음 중 폭포수 방법론보다 애자일 소프트웨어 개발 방법론을 사용할 때의 이점은 무엇입니까?
정답: B
Explanation
The advantage of using agile software development methodology over the waterfall methodology is that it allows for quicker deliverables. Agile software development is an iterative and incremental approach that emphasizes customer feedback, collaboration, and adaptation. Agile software development delivers working software in short cycles, called sprints, that typically last from two to four weeks. This enables the development team to respond to changing requirements, deliver value faster, and improve quality. Waterfall software development is a linear and sequential approach that follows a predefined set of phases, such as planning, analysis, design, implementation, testing, and maintenance. Waterfall software development requires a clear and stable definition of the project scope, deliverables, and expectations before starting the development process. Waterfall software development can be slow, rigid, and costly, especially if changes occur during the later stages of the project. References: CISA Review Manual (Digital Version), Chapter 3:
