Security in CPU Virtualization: Threats, Isolation, and Mitigation
As cloud computing continues to scale globally, CPU virtualization in cloud computing remains one of the foundational technologies enabling multi-tenancy, scalability, and resource abstraction. However, while virtualization boosts efficiency and flexibility, it also opens the door to a new class of security risks. In this post, we’ll explore the security implications of CPU virtualization , outline common threats , and discuss isolation techniques and mitigation strategies that are critical to protecting virtualized cloud environments. What Is CPU Virtualization in Cloud Computing? CPU virtualization allows a single physical processor to be shared by multiple virtual machines (VMs), each appearing to run independently. A hypervisor manages the CPU scheduling and isolation between VMs. In the context of CPU virtualization in cloud computing , this enables providers like AWS, Azure, and GCP to host multiple customers (tenants) on the same physical server — but in isolated e...
