 Supply chain agreements between a cloud service provider and cloud customers should, at a minimum, include audits, assessments, and independent verification of compliance certifications with agreement terms. This is because cloud services involve multiple parties in the supply chain, such as cloud providers, sub-providers, brokers, carriers, and auditors. Each party may have different roles and responsibilities in delivering the cloud services and ensuring their quality, security, and compliance. Therefore, it is important for the cloud customers to have visibility and assurance of the performance and compliance of the cloud providers and their sub-providers. Audits, assessments, and independent verification of compliance certifications are methods to evaluate the effectiveness of the controls and processes implemented by the cloud providers and their sub-providers to meet the agreement terms. These methods can help the cloud customers to identify any gaps or risks in the supply chain and to take corrective actions if needed. This is part of the Cloud Control Matrix (CCM) domain COM-04: Audit Assurance & Compliance, which states that "The organization should have a policy and procedures to conduct audits and assessments of cloud services and data to verify compliance with applicable regulatory frameworks, contractual obligations, and industry standards."12 References := CCAK Study Guide, Chapter 3: Cloud Compliance Program, page 551; Practical Guide to Cloud Service Agreements Version 2.02

A centralized risk and controls dashboard is the best option for ensuring a coordinated approach to risk and control processes when duties are split between an organization and its cloud service providers. This dashboard provides a unified view of risk and control status across the organization and the cloud services it utilizes. It enables both parties to monitor and manage risks effectively and ensures that control activities are aligned and consistent. This approach supports proactive risk management and facilitates communication and collaboration between the organization and the cloud service provider.

References = The concept of a centralized risk and controls dashboard is supported by the Cloud Security Alliance (CSA) and ISACA, which emphasize the importance of visibility and coordination in cloud risk management. The CCAK materials and the Cloud Controls Matrix (CCM) provide guidance on establishing such dashboards as a means to manage and mitigate risks in a cloud environment12.

 A contract containing the phrase “You automatically consent to these terms by using or logging into the service to which they pertain” is establishing a contract of adhesion. A contract of adhesion is a type of legal agreement that involves one party setting the terms and conditions and the other party having no choice but to accept or reject them without bargaining. These contracts are often used in situations where one party has more power or resources than the other, such as in online services, insurance, leases, or consumer credit. These contracts may be unfair or unclear to the weaker party and may be challenged in court for unconscionability or ambiguity12.

The cloud service provider is responsible for the patching of the hypervisor layer in all three cloud deployment models (IaaS, PaaS, and SaaS). The hypervisor layer is the software that allows the creation and management of virtual machines on a physical server. The hypervisor layer is part of the cloud infrastructure, which is owned and operated by the cloud service provider. The cloud service provider is responsible for ensuring that the hypervisor layer is secure, reliable, and up to date with the latest patches and updates. The cloud service provider should also monitor and report on the status and performance of the hypervisor layer, as well as any issues or incidents that may affect it.

The cloud service customer is not responsible for the patching of the hypervisor layer, as they do not have access or control over the cloud infrastructure. The cloud service customer only has access and control over the cloud resources and services that they consume from the cloud service provider, such as virtual machines, storage, databases, applications, etc. The cloud service customer is responsible for ensuring that their own cloud resources and services are secure, compliant, and updated with the latest patches and updates.

The patching of the hypervisor layer is not a shared responsibility between the cloud service provider and the cloud service customer, as it is solely under the domain of the cloud service provider. The shared responsibility model in cloud computing refers to the division of security and compliance responsibilities between the cloud service provider and the cloud service customer, depending on the type of cloud deployment model. For example, in IaaS, the cloud service provider is responsible for securing the physical infrastructure, network, and hypervisor layer, while the cloud service customer is responsible for securing their own operating systems, applications, data, etc. In PaaS, the cloud service provider is responsible for securing everything up to the platform layer, while the cloud service customer is responsible for securing their own applications and data. In SaaS, the cloud service provider is responsible for securing everything up to the application layer, while the cloud service customer is responsible for securing their own data and user access.

Patching on hypervisor layer is required, as it is essential for maintaining the security, reliability, and performance of the cloud infrastructure. Patching on hypervisor layer can help prevent vulnerabilities, bugs, errors, or exploits that may compromise or affect the functionality of the virtual machines or other cloud resources and services. Patching on hypervisor layer can also help improve or enhance the features or capabilities of the hypervisor software or hardware. References :=
