Delphi is a database designed to centralize and distribute current industrial automation vulnerability information. Over the past two years, with the aid of many of the world's largest equipment vendors and operators, we have populated this databse through extensive testing of industrial control devices. Delphi stores over 500 vulnerabilities on 31...

The use of firewalls between business and process control networks is often suggested as an ideal solution for plant floor cyber security. But research shows that few firewalls are properly configured and that many control system security incidents bypass the firewall. If firewalls are to be effective, guidance on how to deploy them in industrial s...

We explore the properties of some sequences for which a(n-a(n))=0. Under the natural restriction that a(n) < n the number of such sequences is a Bell number. Adding other natural restrictions yields sequences counted by the Catalan numbers, the Narayana numbers, the triangle of triangular binomial coefficients, and the Schroder numbers.

The recent introduction of information technologies such as Ethernet® into nuclear industry control devices has resulted in significantly less isolation from the outside world. This raises the question of whether these systems could be attacked by malware, network hackers or professional criminals to cause disruption to critical operations in a man...
