Abstract
Systems and methods are provided for preventing unauthorized modification of an operating system. The system includes an operating system comprised of kernel code for controlling access to operation of a processing unit. The system further includes an enforcement agent executing at a higher privilege than the kernel code such that any changes to the kernel code are approved by the enforcement agent prior to execution.
