A data processing system comprising a processor and a non-transitory computer readable medium having stored thereon: instructions for a behavior measurement architecture derived from an integrity measurement architecture, which instructions, when executed by the data processing system, cause the data processing system to use an identity model to express, on the basis of actor and subject identity interactions each of which are composed of multiple dimensional elements, a deterministic measurement value representative of behavior of an endpoint device of a group of service-providing network endpoints or a platform of the group of service-providing network endpoints hosted on the endpoint device; and instructions for a security supervisor program provided by the BMA and implemented through a daemon or an operating system program, which instructions, when executed by the data processing system, cause the data processing system to: generate a unique identity for the endpoint device based on the identity model including a hash function, wherein the deterministic measurement value includes the unique identity for the endpoint device; verify behavior of the endpoint device or the platform using the unique identity; uphold a pre-defined behavioral state of the endpoint device or the platform and support execution of application instructions stored in memory of the endpoint device using the unique identity; and execute a pre-determined action, via itself or a device derived from the security supervisor program, if a behavior of the endpoint device or the platform is inconsistent with the pre-defined behavioral state of the endpoint device or the platform, according the unique identity of the endpoint device. instructions for a behavior measurement architecture derived from an integrity measurement architecture, which instructions, when executed by the data processing system, cause the data processing system to use an identity model to express, on the basis of actor and subject identity interactions each of which are composed of multiple dimensional elements, a deterministic measurement value representative of behavior of an endpoint device of a group of service-providing network endpoints or a platform of the group of service-providing network endpoints hosted on the endpoint device; and instructions for a security supervisor program provided by the BMA and implemented through a daemon or an operating system program, which instructions, when executed by the data processing system, cause the data processing system to: generate a unique identity for the endpoint device based on the identity model including a hash function, wherein the deterministic measurement value includes the unique identity for the endpoint device; verify behavior of the endpoint device or the platform using the unique identity; uphold a pre-defined behavioral state of the endpoint device or the platform and support execution of application instructions stored in memory of the endpoint device using the unique identity; and execute a pre-determined action, via itself or a device derived from the security supervisor program, if a behavior of the endpoint device or the platform is inconsistent with the pre-defined behavioral state of the endpoint device or the platform, according the unique identity of the endpoint device. generate a unique identity for the endpoint device based on the identity model including a hash function, wherein the deterministic measurement value includes the unique identity for the endpoint device; verify behavior of the endpoint device or the platform using the unique identity; uphold a pre-defined behavioral state of the endpoint device or the platform and support execution of application instructions stored in memory of the endpoint device using the unique identity; and execute a pre-determined action, via itself or a device derived from the security supervisor program, if a behavior of the endpoint device or the platform is inconsistent with the pre-defined behavioral state of the endpoint device or the platform, according the unique identity of the endpoint device.
