Abstract
Methods, systems, and computer readable media for active monitoring, memory protection, and integrity verification of a target device are disclosed. For example, a normal world virtual processor and a secure world virtual processor are instantiated on a target device. A target operating system is executed on the normal world virtual processor. An integrity verification agent is executed on the secure world virtual processor. One or more predetermined operations attempted on the normal world virtual processor are trapped to the secure world virtual processor. The integrity verification agent is used to determine the effect of the execution of the trapped operations on the target device.
