  • Network monitoring system for operational technology devices
    Patent number: 12379714
    Abstract: Embodiments of this present disclosure include an industrial automation system, including an operational technology (OT) industrial automation device. The OT industrial automation device may perform an operation for the industrial automation system. Further, the OT industrial automation device may receive data comprising instructions related to the operation. Embodiments also include a monitoring device to receive the data; identify the OT industrial automation device based on the data; retrieve one or more rules for providing communications to the OT industrial automation device in response to identifying the OT industrial automation device; and selectively forward the data to the OT industrial automation device based on the one or more rules.
    Type: Grant

  • Use of physical unclonable functions to prevent counterfeiting of industrial control products
    Patent number: 11889002
    Abstract: Techniques for authenticating industrial devices in an industrial automation environment are disclosed herein. In at least one implementation, a physical unclonable function response of an industrial device is extracted. The industrial device transmits a security certificate signed by a certificate authority that includes a device public key to a system, wherein the system validates the security certificate, encrypts an authentication challenge using the device public key, and transmits the authentication challenge to the industrial device. The industrial device generates a device private key using the physical unclonable function response and decrypts the authentication challenge using the device private key.
