Which of the following would be considered as a factor to trust in a cloud service provider?
Correct Answer: C
Explanation:
Trust in a cloud service provider is fundamentally based on the assurance that the provider can deliver secure and reliable services. The level of proven technical skills is a critical factor because it demonstrates the provider’s capability to implement and maintain robust security measures, manage complex cloud infrastructures, and respond effectively to technical challenges. Technical expertise is essential for establishing trust, as it directly impacts the security and performance of the cloud services offered.
References = The importance of technical skills in establishing trust is supported by the resources provided by ISACA and the Cloud Security Alliance (CSA). These resources emphasize the need for cloud service providers to have a strong technical foundation to ensure the fulfillment of internal requirements, proper controls, and compliance with regulations, which are crucial for maintaining customer trust and mitigating risks 1 2 3 4 .
Question 2
Regarding suppliers of a cloud service provider, it is MOST important for the auditor to be aware that the:
Correct Answer: D
Explanation:
It is most important for the auditor to be aware that the client organization has a clear understanding of the provider’s suppliers. The provider’s suppliers are the third-party entities that provide services or products to the provider, such as infrastructure, software, hardware, or support. The provider’s suppliers may have a significant impact on the quality, security, reliability, and performance of the cloud services that the provider delivers to the client organization. Therefore, the auditor should ensure that the client organization knows who the provider’s suppliers are, what services or products they provide, what risks they pose, and what contractual or regulatory obligations they have 1 2 3 .
The other options are not correct. Option A, the client organization does not need to worry about the provider’s suppliers, as this is the provider’s responsibility, is incorrect because the client organization cannot rely solely on the provider to manage its suppliers. The client organization has to perform due diligence and oversight on the provider’s suppliers, as they may affect the client organization’s own security, compliance, and business objectives 1 2 . Option B, the suppliers are accountable for the provider’s service that they are providing, is incorrect because the suppliers are not directly accountable to the client organization, but to the provider. The provider is ultimately accountable to the client organization for its service delivery and performance 1 2 . Option C, the client organization and provider are both responsible for the provider’s suppliers, is incorrect because the responsibility for the provider’s suppliers depends on the shared responsibility model, which defines how the security and compliance tasks and obligations are divided between the provider and the client organization. The shared responsibility model may vary depending on the type and level of cloud service that the provider offers 1 2 .

Question 3
Which of the following is the BEST tool to perform cloud security control audits?
Correct Answer: A
Explanation:
The CSA Cloud Controls Matrix (CCM) is the best tool to perform cloud security control audits, as it is a cybersecurity control framework for cloud computing that is aligned to the CSA best practices and is considered the de-facto standard for cloud security and privacy 1 . The CCM provides a set of 197 control objectives that are structured in 17 domains covering all key aspects of cloud technology, such as identity and access management, data security, encryption and key management, business continuity and disaster recovery, audit assurance and compliance, and risk management 1 . The CCM also maps the controls to various industry-accepted security standards, regulations, and control frameworks, such as ISO 27001/27002/27017/27018, NIST SP 800-53, PCI DSS, GDPR, and others 1 . The CCM can be used as a tool for the systematic assessment of a cloud implementation, and provides guidance on which security controls should be implemented by which actor within the cloud supply chain 1 . The CCM also includes the Consensus Assessment Initiative Questionnaire (CAIQ), which provides a set of “yes or no” questions based on the security controls in the CCM that can be used to assess a cloud service provider 2 .
The other options are not the best tools to perform cloud security control audits, as they are either not specific to cloud computing or not comprehensive enough. GDPR is a regulation that aims to protect the personal data and privacy of individuals in the European Union and the European Economic Area 3 , but it does not provide a framework for cloud security controls. FIPS 140-2 is a standard that specifies the security requirements for cryptographic modules used by federal agencies in the United States, but it does not cover other aspects of cloud security. ISO 27001 is a standard that specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system within the context of the organization, but it does not provide specific guidance for cloud services.
