CISA-KR 문제 181
다음 중 분실된 회사 소유 모바일 장치에 대한 무단 액세스 위험을 최소화하기 위한 최선의 제어는 무엇입니까?
정답: C
Explanation
The best control to minimize the risk of unauthorized access to lost company-owned mobile devices is device encryption. Device encryption is a process that transforms data on a device into an unreadable format using a cryptographic key. Device encryption protects the data stored on the device from being accessed by unauthorized parties, even if they bypass the password or PIN protection. Device encryption can also prevent data leakage if the device is disposed of or recycled without proper data sanitization. Password or PIN protection is a basic control that prevents unauthorized access to the device by requiring a secret code or pattern to unlock it. However, password or PIN protection can be easily compromised by brute force attacks, shoulder surfing, or social engineering. Device tracking software is a tool that allows the device owner or administrator to locate, lock, or wipe the device remotely in case of loss or theft. However, device tracking software depends on the device's network connectivity and GPS functionality, which may not be available or reliable in some situations. Periodic backup is a process that copies the data from the device to another storage location for recovery purposes. Periodic backup can help restore the data in case of loss or damage of the device, but it does not prevent unauthorized access to the data on the device itself.

CISA-KR 문제 182
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. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.2.2

CISA-KR 문제 183
다음 중 조직의 외국 사이버 보안 규정 준수 여부를 감사할 때 가장 유용한 것은 무엇입니까?
정답: D
Explanation
The most useful thing to do when planning to audit an organization's compliance with cybersecurity regulations in foreign countries is to map the different regulatory requirements to the organization's IT governance framework. This is because an IT governance framework is a roadmap that defines the methods used by an organization to implement, manage and report on IT governance within said organization1. IT governance helps align business and IT strategies using a solid and formal framework2. By mapping the different regulatory requirements to the IT governance framework, the auditor can:
Identify the commonalities and differences among the various cybersecurity regulations that apply to the organization's operations in different countries.
Assess the level of compliance and maturity of the organization's IT governance practices against each regulatory requirement.
Evaluate the risks and gaps associated with non-compliance or partial compliance with any of the regulatory requirements.
Recommend appropriate actions or improvements to enhance the organization's IT governance and cybersecurity posture.
Option D is correct because mapping the different regulatory requirements to the organization's IT governance framework is a systematic and effective way to plan and conduct an audit of compliance with cybersecurity regulations in foreign countries.

한 조직이 거래량이 많은 복잡한 시스템에서 중복 공급업체 지불에 대해 우려하고 있습니다. 다음 중 IS 감사인이 중복 공급업체 지급 여부를 판단하는 데 가장 도움이 되는 것은 무엇입니까?
정답: A
Explanation
A computer-assisted technique is the most helpful method for an IS auditor to determine whether duplicate vendor payments exist on a complex system with a high volume of transactions. A computer-assisted technique is a tool or procedure that can be used to perform audit tests or procedures on data stored in electronic form.
Examples of computer-assisted techniques include data analysis software, query tools, scripting languages, and specialized audit software. A computer-assisted technique can help an IS auditor to identify and extract duplicate payments from a large data set, perform calculations and comparisons, and generate reports and summaries. A computer-assisted technique can also provide more accuracy, efficiency, and coverage than manual methods.
Stratified sampling, statistical sampling, and process walk-through are not as helpful as a computer-assisted technique for this purpose. Stratified sampling is a sampling method that divides the population into subgroups based on certain characteristics and selects samples from each subgroup. Statistical sampling is a sampling method that uses probability theory to determine the sample size and selection criteria. Process walk-through is a review technique that involves following a transaction or process from start to finish and observing the inputs, outputs, controls, and documentation. These methods may be useful for other audit objectives, but they are not as effective as a computer-assisted technique for detecting duplicate payments in a complex and high-volume system.

CISA-KR 문제 185
조직의 정보 보안 정책을 검토할 때 IS 감사인은 정책이 주로 다음을 기반으로 정의되었는지 확인해야 합니다.
정답: A
Explanation
Information security policies are high-level statements that define the organization's approach to protecting its information assets from threats and risks. They should be based primarily on a risk management process, which is a systematic method of identifying, analyzing, evaluating, treating, and monitoring information security risks. A risk management process can help ensure that the policies are aligned with the organization's risk appetite, business objectives, legal and regulatory requirements, and stakeholder expectations. An information security framework is a set of standards, guidelines, and best practices that provide a structure for implementing information security policies. It can support the risk management process, but it is not the primary basis for defining the policies. Past information security incidents and industry best practices can also provide valuable inputs for defining the policies, but they are not sufficient to address the organization's specific context and needs.
