Techniques for improved run time trustworthiness

Techniques are presented herein for attesting the trustworthiness of devices in a secure network during run-time operation. A security management device is configured to perform network trust attestation operations in order to generate an access control policy that defines access rights for a device in a network. The access control policy is assured by creating a hash value for the access control policy and then signing the hash value to generate a signed hash value. The signed hash value is integrated with the access control policy, and the access control policy is sent with the signed hash value to the operator device for verification.
