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： End-to-end security between clients and a server, and traffic visibility to intermediate network devices, achieved through combined mode, single pass encryption and authentication using two keys is disclosed. In various embodiments, a combined encryption-authentication unit includes a cipher unit and an authentication unit coupled in parallel to the cipher unit, and generates an authentication tag using an authentication key in parallel with the generation of the cipher text using an encryption key, where the authentication and encryption key have different key values. In various embodiments, the cipher unit operates in AES counter mode, and the authentication unit operates in parallel, in AES-GMAC mode Using a two key, single pass combined mode algorithm preserves network performance using a limited number of HW gates, while allowing an intermediate device access to the encryption key for deciphering the data, without providing that device the ability to compromise data integrity, which is preserved between the end to end devices.

摘要： According to some embodiments, a system provides a resource service module, a resource data record repository, and a provider module. The resource service module exposes an interface, receives an invocation of the interface from a system management module, and requests managed resource data associated with a manageable resource based on the invocation. The resource data record repository includes a resource data record indicating a memory location of a managed host in which the managed resource data is stored, and the provider module receives the request and to retrieve the managed resource data from the memory location of the managed host.
