CISA-KR 문제 171
다음 중 알려진 취약점에 대해 미션 크리티컬 비즈니스 애플리케이션 서버를 패치할 때 가장 중요한 고려 사항은 무엇입니까?
정답: A
Explanation
The most important consideration for patching mission critical business application servers against known vulnerabilities is A. Patches are implemented in a test environment prior to rollout into production. This is because patching mission critical business application servers involves a high level of risk and complexity, and requires careful planning and testing before applying the patches to the live environment. Patches may introduce new bugs, errors, or conflicts that could affect the functionality, performance, or security of the application servers, and cause system downtime, data loss, or business disruption1. Therefore, it is essential to implement patches in a test environment first, where the patches can be verified and validated for their effectiveness and compatibility, and any issues or defects can be identified and resolved before they impact the production environment2.

다음 중 위험 기반 감사 전략을 개발할 때 IS 감사인이 중점을 두는 가장 중요한 영역은 무엇입니까?
정답: B
Explanation
This is because the business processes are the core activities and functions that enable the organization to achieve its objectives and create value for its stakeholders. The business processes are also the sources and drivers of various risks that may affect the organization's performance, compliance, and reputation. Therefore, the IS auditor should focus on understanding, assessing, and prioritizing the business processes that are most critical, complex, or vulnerable to the organization's success, and align the audit objectives, scope, and resources accordingly12.
Critical business applications (A) are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather a specific aspect of the business processes that may require attention.
Critical business applications are the software systems that support the execution and automation of the business processes, such as enterprise resource planning (ERP), customer relationship management (CRM), or accounting systems. Critical business applications may pose significant risks to the organization if they are not reliable, secure, or efficient. Therefore, the IS auditor should consider the criticality, functionality, and dependency of the business applications when planning the audit, but not as the primary focus12.
Existing IT controls are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather an outcome or output of the risk assessment process. Existing IT controls are the policies, procedures, practices, and technologies that are implemented to manage and mitigate the IT-related risks that may affect the organization's business processes and objectives. Existing IT controls may vary in their design, effectiveness, and maturity. Therefore, the IS auditor should evaluate and test the existing IT controls as part of the audit execution and reporting process, but not as the main focus12.
Recent audit results (D) are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather an input or source of information for the risk assessment process. Recent audit results are the findings, recommendations, and opinions of previous audits that may provide insights or feedback on the organization's business processes, risks, and controls. Recent audit results may also indicate any changes or trends in the organization's risk profile or environment. Therefore, the IS auditor should review and consider the recent audit results as part of the audit planning and scoping process, but not as the main focus12.

CISA-KR 문제 173
IS 감사인이 감사에 중요성 개념을 적용하는 것이 언제 가장 중요합니까?
정답: A
Explanation
The concept of materiality is most important for an IS auditor to apply when planning an audit engagement, because it helps the auditor to determine the scope, objectives, procedures and resources of the audit.
Materiality is the degree to which an omission or misstatement of information could affect the users' decisions or the achievement of the audit objectives. By applying the concept of materiality, the auditor can focus on the most significant and relevant areas of the audit and avoid wasting time and effort on trivial or immaterial matters. The other options are not as important as planning an audit engagement, because they are either based on or affected by the materiality assessment done during the planning phase. References:

CISA-KR 문제 174
데스크톱 PC가 많은 조직에서 씬 클라이언트 아키텍처로의 전환을 고려하고 있습니다. 다음 중 MAJOR 이점은 무엇입니까?
정답: C
Explanation
The major advantage of moving from many desktop PCs to a thin client architecture is that desktop application software will never have to be upgraded. A thin client architecture is a type of client-server architecture that uses lightweight or minimal devices (thin clients) as clients that connect to a central server that provides most of the processing and storage functions. A thin client architecture can offer several benefits over a traditional desktop PC architecture, such as lower cost, higher security, easier maintenance, etc. One of these benefits is that desktop application software will never have to be upgraded on thin clients, as all the applications are installed and updated on the server, and accessed by thin clients through a network connection. This can save time and money for installing and upgrading software on individual devices, and ensure consistency and compatibility among different devices. The security of the desktop PC is enhanced is a possible advantage of moving from many desktop PCs to a thin client architecture, but it is not the major one.
A thin client architecture can enhance the security of desktop PCs by reducing the exposure or vulnerability of data and applications on individual devices, and centralizing the security management and control on the server. However, this advantage may depend on other factors such as network security, server security, user authentication, etc. Administrative security can be provided for the client is a possible advantage of moving from many desktop PCs to a thin client architecture, but it is not the major one. A thin client architecture can provide administrative security for clients by allowing administrators to configure and manage client devices remotely from the server, and enforce policies and restrictions on client access or usage. However, this advantage may depend on other factors such as network reliability, server availability, user compliance, etc.
System administration can be better managed is a possible advantage of moving from many desktop PCs to a thin client architecture, but it is not the major one. A thin client architecture can improve system administration by simplifying and streamlining the tasks and activities involved in maintaining and supporting client devices, such as backup, recovery, troubleshooting, etc., and consolidating them on the server. However, this advantage may depend on other factors such as network bandwidth, server capacity, user satisfaction

네트워크 모니터링과 관련된 제어 설계를 평가할 때 다음 중 IS 감사인이 검토해야 할 가장 중요한 것은 무엇입니까?
정답: D
Explanation
Network topology diagrams are the most important for an IS auditor to review when evaluating the design of controls related to network monitoring, because they show how the network components are connected and configured, and what security measures are in place to protect the network from unauthorized access or attacks. Incident monitoring logs, the ISP service level agreement, and reports of network traffic analysis are useful for evaluating the effectiveness and performance of network monitoring, but not the design of controls.
References: CISA Review Manual (Digital Version), Chapter 5, Section 5.3.3
