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 :=

Access controls are the aspect of Software as a Service (SaaS) functionality and operations that the cloud customer is responsible for and should be audited. Access controls refer to the methods and techniques that verify the identity and access rights of users or devices that access or use the SaaS application and its data. Access controls may include credentials, policies, roles, permissions, tokens, multifactor authentication, single sign-on, etc. The cloud customer is responsible for ensuring that only authorized and legitimate users or devices can access or use the SaaS application and its data, as well as for protecting the confidentiality, integrity, and availability of their data. The cloud customer should also monitor and audit the access and usage of the SaaS application and its data, as well as any incidents or issues that may affect them123.

Source code reviews (A) are not the aspect of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Source code reviews refer to the processes and practices that examine the source code of software applications or systems to identify errors, bugs, vulnerabilities, or inefficiencies that may affect their quality, functionality, or security. Source code reviews are mainly under the responsibility of the cloud service provider, as they own and operate the software applications or systems that deliver SaaS services. The cloud customer has no access or control over these aspects123.

Patching (B) is not the aspect of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Patching refers to the processes and practices that ensure the security, reliability, and performance of the cloud infrastructure, platform, or software. Patching involves the use of updates or fixes to address vulnerabilities, bugs, errors, or exploits that may compromise or affect the functionality of the cloud components. Patching is mainly under the responsibility of the cloud service provider, as they own and operate the cloud infrastructure, platform, or software. The cloud customer has limited or no access or control over these aspects123.

Vulnerability management (D) is not the aspect of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Vulnerability management refers to the processes and practices that identify, assess, treat, monitor, and report on the risks that affect the security posture of an organization or a domain. Vulnerability management involves the use of tools or techniques to scan, analyze, prioritize, remediate, or mitigate vulnerabilities that may expose an organization or a domain to threats or attacks. Vulnerability management is mainly under the responsibility of the cloud service provider, as they own and operate the cloud infrastructure, platform, or software. The cloud customer has limited or no access or control over these aspects123. References :=
