A New Trusted Network that could secure critical infrastructures

A company called UniLock announced the development of ” a physical device recognition technology that samples about 10,000 different characteristics of a device to make up a unique “fingerprint” for the device. In addition to the obvious differentiators such as board and chip serial numbers and network MAC addresses, Uniloc’s client software looks at the unique pattern of defects in the disk media, the exact speed of chip sets, and other physical imperfections, to create a robust identifier.

What about legacy devices, such as PLCs (programmable logic controllers) or sensors, such as oil pipeline flowmeters? They can’t be fingerprinted directly, but a small NetAnchor appliance can be inserted between the appliance and the network to provide the unique fingerprint.

Once every device on a network has been identified and authenticated to a NetAnchor server, it becomes very difficult (Uniloc would say impossible) for an intruder to breach the network without gaining physical access to an authenticated device. This greatly reduces the attack surface of the network.” Full Article HERE

I think this technology and others of the sort can take-off because it solves a current SCADA dilemma, Particularly the implementations that depend on scattered, Remote (Out of Physical boundary ) RTUs and PLCs . It has always been a debate on how to secure those remote/unmonitored devices…encryption was the first option but it has a downside in terms of Latency / processing overhead and the limited ability to Manage encryption keys in 24/7 mission critical environments.
