    Abstract: Systems, methods, and computer-readable media for evaluation of trustworthiness of network devices are proposed. In one aspect, a first network device can determine a first determine a first probability of a security compromise of a second network device based on visible indicators. The first network device can also determine a second probability of the security compromise of the second device based on invisible indicators. The first network device also determines a trust degradation score for the second network device and establishes, based on the trust degradation score, a specified type of communication session with the second network device.

    Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media for providing security postures for a service provided by a heterogenous system. A method for verifying trust by a service node includes receiving a request for a security information of the service node from a client device, wherein the request includes information identifying a service to receive from the service node, identifying a related node to communicate with the service node based on the service, after identifying the related node, requesting a security information of the related node, generating a composite security information from the security information of the service node and the security information of the related node, and sending the composite security information to the client device. The composite security information provides security claims for a service implemented by a heterogenous devices that have different trusted execution environments.
