As old-school industries like oil and gas increasingly network entities like oil platforms, they become more vulnerable to hacking attacks that were impossible when they were stand-alone. That requires a new approach to security and Xage (pronounced Zage), a security startup that launched last year thinks it has the answer with a concept called ‘fingerprinting’ combined with the blockchain.

“Each individual fingerprint tries to reflect as much information as possible about a device or controller,” Duncan Greatwood, Xage’s CEO explained. They do this by storing configuration data from each device and controller on the network. That includes the hardware type, the software that’s installed on it, the CPU ID, the storage ID and so forth.

If someone were to try to inject malware into one of these controllers, the fingerprint identification would notice a change and shut it down until human technicians could figure out if it’s a legitimate change or not.

Whither blockchain?

You may be wondering where the blockchain comes into this, but imagine a honey pot of these fingerprints were stored in a conventional database. If that database were compromised, it would mean hackers could have access to a company’s entire store of fingerprints, completely neutering that idea. That’s where the blockchain comes in.

Greatwood says it serves multiple purposes to prevent such a scenario from happening. For starters, it takes away that centralized honey pot. It also provides a means of authentication making it impossible to insert a fake fingerprint without explicit permission to…
