Shared Responsibility Model

VMware shared responsibility is a security model that defines the security responsibilities of both VMware and its customers in a shared IT environment. The shared responsibility model helps to clarify the responsibilities of each party and ensure that security risks are addressed appropriately.

In the shared responsibility model, VMware is responsible for the security of the cloud infrastructure, including the underlying hardware, storage, and networking infrastructure. VMware is also responsible for maintaining the security of the hypervisor and other virtualization components.

Customers are responsible for securing their virtual machines, operating systems, applications, and data that run on the cloud infrastructure. Customers must ensure that their applications and data are protected against unauthorized access, data breaches, and other security threats. Customers are also responsible for ensuring that they comply with industry regulations and standards.

The shared responsibility model is important because it ensures that both VMware and its customers understand their roles and responsibilities in securing the IT environment. By working together, VMware and its customers can ensure that the cloud infrastructure and applications are secure, compliant, and protected against potential threats.
