다음 중 다중 테넌트 클라우드 환경에서 데이터 유출 방지를 가장 효과적으로 시행하는 방법은 무엇입니까?
정답: D
Data leakage prevention (DLP) is the process of preventing unauthorized access, disclosure, or transfer of sensitive data. In a multi-tenant cloud environment, where multiple customers share the same infrastructure and resources, DLP is a critical challenge. One of the best methods to enforce DLP in such an environment is to require tenants to implement data classification policies. Data classification policies define the types and levels of sensitivity of data, and the corresponding security controls and measures to protect them. By implementing data classification policies, tenants can ensure that their data is properly labeled, encrypted, segregated, and monitored according to their specific requirements and compliance standards. This can help prevent data leakage from accidental or malicious actions by other tenants, cloud service providers, or external parties.

데스크톱 PC가 많은 조직에서 씬 클라이언트 아키텍처로의 전환을 고려하고 있습니다. 다음 중 가장 큰 이점은 무엇입니까?
정답: C
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

방화벽에서 기업의 내부 리소스를 보호하기 위해 다음 중 어떤 것을 사용합니까?
정답: C
Internet Protocol (IP) address restrictions are used in a firewall to protect the entity's internal resources by allowing or denying access to specific IP addresses or ranges of IP addresses based on predefined rules.
Remote access servers, Secure Sockets Layers (SSLs), and failover services are not directly related to firewall protection, but rather to other aspects of network security, such as authentication, encryption, and availability. References: CISA Review Manual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.2: Network Security Devices and Technologies

CISA-KR 문제 219
데이터 소유자가 데이터에 잘못된 분류 수준을 지정한 경우 IS 감사자가 가장 우려해야 할 사항은 무엇입니까?
정답: A
The answer A is correct because the greatest concern for an IS auditor when a data owner assigns an incorrect classification level to data is that controls to adequately safeguard the data may not be applied. Data classification is the process of categorizing data assets based on their information sensitivity and business impact. Data classification helps organizations to identify, protect, and manage their data according to their value and risk. Data owners are the individuals or entities who have the authority and responsibility to define, classify, and control the access and use of their data.
Data classification typically involves assigning labels or tags to data assets, such as public, internal, confidential, or restricted. These labels indicate the level of protection and handling required for the data.
Based on the data classification, organizations can implement appropriate controls to safeguard the data, such as encryption, access control lists, audit logs, backup policies, etc. These controls help to prevent unauthorized access, disclosure, modification, or loss of data, and to ensure compliance with relevant laws and regulations.
If a data owner assigns an incorrect classification level to data, it can result in either underprotection or overprotection of the data. Underprotection means that the data is classified at a lower level than it should be, which exposes it to higher risks of compromise or breach. For example, if a data owner classifies personal health information (PHI) as public instead of confidential, it may allow anyone to access or share the data without proper authorization or consent. This can violate the privacy rights of the data subjects and the compliance requirements of regulations such as HIPAA (Health Insurance Portability and Accountability Act). Overprotection means that the data is classified at a higher level than it should be, which limits its availability or usability. For example, if a data owner classifies marketing materials as restricted instead of public, it may prevent potential customers or partners from accessing or viewing the data. This can reduce the business value and opportunities of the data.
Therefore, an IS auditor should be concerned about the accuracy and consistency of data classification by data owners, as it affects the security and efficiency of data management. An IS auditor should review the policies and procedures for data classification, verify that the data owners have adequate knowledge and skills to classify their data, and test that the data classification labels match with the actual sensitivity and impact of the data.
