Blockchain verification of network security service

Abstract:

According to some embodiments, a system may include a communication port to exchange information with a client device associated with an industrial control system. A network security server coupled to the communication port may include a computer processor adapted to provide a network security service for the client device. The computer processor may further be adapted to record security information about the client device via a blockchain verification process (e.g., by registering a validation result within a distributed ledger). The network security service might comprise, for example, an integrity attestation service providing software verification for the client device.
