Abstract
The concepts, systems and methods described herein are directed towards a method running on a security device. The method is provided to including: executing a first secure boot code from a first memory by one of a plurality of cores of a processor, wherein the plurality of cores runs in a secure world; executing a first-stage boot loader (FSBL) from a second memory; executing a security monitoring application to validate the security device; in response to the security device being validated, switching some of the plurality of cores from the secure world to a normal world, wherein at least one of the plurality of cores remains in the secure world to communicate with the security monitoring application; executing a second-stage boot loader (SSBL); and monitoring, via the security monitoring application, status of the security device and communications between the security device and at least one external system.
