Techniques for evaluating cyber assets are disclosed. A system obtains, from data sources in an experimental environment, raw data generated in response to execution of a cyber asset. The system generates, from the raw data, at least one instance model corresponding to the data sources. The at least one instance model includes instances of concepts represented in a cyber impact ontology.

Systems and methods for evaluating cyber assets

Techniques for enforcing trust policies for payload data transmitted through a data provisioning layer include: receiving, by a node in the data provisioning layer, payload data to be delivered to a recipient; obtaining, by the node, a trust policy indicating multiple attributes used to determine trustworthiness of payloads; determining, by the node, a set of values of the attributes associated with the payload data; generating, by the node, a trustworthiness opinion based at least on the trust policy and the set of values of the attributes; transmitting, by the node, the payload data and the trustworthiness opinion via the data provisioning layer toward the recipient; computing, by the recipient, a trustworthiness metric associated with the payload data based at least on the trustworthiness opinion; and determining, by the recipient, an action to take with respect to the payload data based at least on the trustworthiness metric.

Trust policies for a data provisioning layer

Techniques for metadata-based information provenance are disclosed. A node in a data provisioning layer receives encrypted payload data to be delivered to a recipient. The node generates provenance metadata that describes at least one action taken by the node with respect to the encrypted payload data. The node transmits the encrypted payload data and the provenance metadata via the data provisioning layer toward the recipient.
