Threat-aware architecture
Last updated:
Abstract:
An architecture deployed to facilitate real-time security analysis, including exploit detection and threat intelligence, of operating system (OS) processes executed by a central processing unit (CPU). The architecture features memory configured to store a process, an OS kernel, a VMM and a virtualization module. The virtualization module is configured to communicate with the VMM and execute, at a privilege level of the CPU, to control access permissions to kernel resources accessible by the process. The VMM is configured to execute at a first privilege level of the virtualization module to expose the kernel resources to the OS kernel. The OS kernel is configured to execute at a second privilege level lower than the first privilege level of the virtualization module. The VMM is further configured to instantiate a virtual machine containing the OS kernel, where access to the kernel resources is controlled by the VMM and the virtual machine.
