Abstract: A system, method, and apparatus are provided for securely controlling operations of a data processing system in which security subsystem is activated to provide security services by responding to a security service request, evaluating the request against an adjustable set of system security policies to determine if the security service request is granted access to a protected asset, by generating a response to the security service request using the protected asset if the security service request is granted access to the protected asset, by adjusting a security access policy for the protected asset in the adjustable set of system security policies, and by sending the response from the security subsystem to the external application subsystem.
