 The BSI Criteria Catalogue C5 is a document that has been provided by the Federal Office for Information Security (BSI) in Germany to support customers in selecting, controlling, and monitoring their cloud service providers (CSPs). The C5 stands for Cloud Computing Compliance Criteria Catalogue and specifies minimum requirements for secure cloud computing. The C5 is primarily intended for professional CSPs, their auditors, and customers of the CSPs. The C5 covers 17 domains and 114 control objectives that address all key aspects of cloud security, such as data protection, identity and access management, encryption and key management, incident response, audit assurance, and compliance. The C5 also maps to other industry-accepted security standards, regulations, and frameworks, such as ISO 27001/27002/27017/27018, NIST SP 800-53, CSA Cloud Controls Matrix (CCM), COBIT, GDPR, etc. The C5 helps customers to evaluate and compare the security and compliance posture of different CSPs, and to verify that the CSPs meet their contractual obligations and legal requirements12.

 The organization (client) is accountable for the use of a cloud service. Accountability in cloud computing is the responsibility of cloud service providers and other parties in the cloud ecosystem to protect and properly process the data of their clients and users. However, accountability ultimately rests with the organization (client) that uses the cloud service, as it is the data owner and controller. The organization (client) has to ensure that the cloud service provider and its suppliers meet the agreed-upon service levels, security standards, and regulatory requirements. The organization (client) also has to perform due diligence and oversight on the cloud service provider and its suppliers, as well as to comply with the shared responsibility model, which defines how the security and compliance tasks and obligations are divided between the cloud service provider and the organization (client)123.

The other options are not correct. Option A, the cloud access security broker (CASB), is incorrect because a CASB is a software tool or service that acts as an intermediary between cloud users and cloud service providers, providing visibility, data security, threat protection, and compliance. A CASB does not use the cloud service, but facilitates its secure and compliant use4. Option B, the supplier, is incorrect because a supplier is a third-party entity that provides services or products to the cloud service provider, such as infrastructure, software, hardware, or support. A supplier does not use the cloud service, but supports its delivery5. Option C, the cloud service provider, is incorrect because a cloud service provider is a company that provides cloud computing services to the organization (client). A cloud service provider does not use the cloud service, but offers it to the organization (client)6. References :=

It is most important for an auditor to be aware that an inventory of assets within a cloud environment is fundamental for the security management program. An inventory of assets is a list of all the hardware, software, data, and services that are owned, used, or managed by an organization in the cloud. An inventory of assets helps the organization to identify, classify, and prioritize its cloud resources and to implement appropriate security controls and policies to protect them. An inventory of assets also helps the organization to comply with relevant regulations, standards, and contracts that may apply to its cloud environment.12

An auditor should be aware of the importance of an inventory of assets in the cloud because it provides a baseline for assessing the security posture and compliance status of the organization’s cloud environment. An auditor can use the inventory of assets to verify that the organization has a clear and accurate understanding of its cloud resources and their characteristics, such as location, ownership, configuration, dependencies, vulnerabilities, and risks. An auditor can also use the inventory of assets to evaluate whether the organization has implemented adequate security measures and processes to protect its cloud resources from threats and incidents. An auditor can also use the inventory of assets to identify any gaps or weaknesses in the organization’s security management program and to provide recommendations for improvement.34

When applying the Top Threats Analysis methodology following an incident, the scope of the technical impact identification step is to determine the impact on confidentiality, integrity, and availability of the information system. The Top Threats Analysis methodology is a framework developed by the Cloud Security Alliance (CSA) to help organizations identify, analyze, and mitigate the most critical threats to cloud computing. The methodology consists of six steps: threat identification, threat analysis, technical impact identification, business impact analysis, risk assessment, and risk treatment12.

The technical impact identification step is the third step of the methodology, and it aims to assess how the incident affected the security properties of the information system, namely confidentiality, integrity, and availability. Confidentiality refers to the protection of data from unauthorized access or disclosure. Integrity refers to the protection of data from unauthorized modification or deletion. Availability refers to the protection of data and services from disruption or denial. The technical impact identification step can help organizations to understand the severity and extent of the incident and its consequences on the information system12.

The other options are not within the scope of the technical impact identification step. Option A, determine the impact on the controls that were selected by the organization to respond to identified risks, is not within the scope because it is part of the risk treatment step, which is the sixth and final step of the methodology. Option C, determine the impact on the physical and environmental security of the organization, excluding informational assets, is not within the scope because it is not related to the information system or its security properties. Option D, determine the impact on the financial, operational, compliance, and reputation of the organization, is not within the scope because it is part of the business impact analysis step, which is the fourth step of the methodology. References :=
