    摘要： A method and apparatus for detection of network environment to aid policy selection for network access control. An embodiment of a method includes receiving a request to connect a device to a network and, if a security policy is received for the connection of the device, applying the policy for the device. If a security policy for the connection of the device is not received, the domain of the device is determined by determining whether the device is in an enterprise domain and determining whether the device is in a network access control domain, which allows selection of an appropriate domain/environment specific policy.

    摘要： A method that includes initiating a network access request from an access requester on a platform that couples to a network, the network access request made to a policy decision point for the network. The method also includes establishing a secure communication channel over a communication link between the policy decision point and a policy enforcement point on the platform. Another secure communication channel is established over another communication link. The other communication link is between at least the policy enforcement point and a manageability engine resident on the platform. The manageability engine forwards posture information associated with the access requester via the other secure communication channel. The posture information is then forwarded to the policy decision point via the secure communication channel between the policy enforcement point and the policy decision point. The policy decision point indicates what access the access requester can obtain to the network based on a comparison of the posture information to one or more network administrative policies.

    摘要： Architectures and techniques that allow a firmware agent to operate as a tamper-resistant agent on a host platform that may be used as a trusted policy enforcement point (PEP) on the host platform to enforce policies even when the host operating system is compromised. The PEP may be used to open access control and/or remediation channels on the host platform. The firmware agent may also act as a local policy decision point (PDP) on the host platform in accordance with an authorized enterprise PDP entity by providing policies if a host trust agent is non-responsive and may function as a passive agent when the host trust agent is functional.

    摘要： Methods and apparatus to off-load cryptographic processes are disclosed. An example method includes receiving a request to perform a cryptographic process at a first component of a processor system, transmitting the request over a data bus to a second component of a processor system, receiving the request at the second component, and performing the cryptographic process on the second component. For example, the first component may be a processor and the second component may be a management agent. Other embodiments are described and claimed.
