Abstract
A data processing system includes a plurality of subsystems, a plurality of local security controllers, and a central security controller. Each subsystem of the plurality of subsystems has a security component for providing a security function. A local security controller corresponds to each one of the subsystems. Each local security controller ensures compliance of the security component with local security policies of the subsystem to which the local security controller corresponds. The central security controller is coupled to the local security controller of each of the plurality of subsystems. The central security controller ensures data processing system compliance with system wide security policies. In the event of a detected security violation, the local security controller may respond automatically, without involvement of the central security controller. A method for securing the data processing system is also provided.
