  • Patent number: 11989302
    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.
    Type: Grant

  • Patent number: 11797681
    Abstract: A system, method, and apparatus are provided for securely controlling operations of a data processing system by activating a security subsystem to control startup behavior of application subsystems, installing SMR parameters which include an initial authenticity proof for use with an initial verification process for the SMR and calculating an alternate authenticity proof for use with a subsequent verification process for the SMR, and then by subsequently verifying the SMR using the alternate authenticity proof for the subsequent verification process applied to the SMR so that the security subsystem can apply a comprehensive system reaction for the application subsystem based on the SMR verification results.
