You have likely never worried about the possibility of a high school geek doing some programming that affects your home water quality. Well, neither had I until I learnt that some municipal networks have no security between the network their schools use and the one that runs their water/wastewater facility.
Practical SCADA Security
Control System Security Threats, Security / Reliability Incidents, Useful Industrial Cyber Security Tips
One of the major differences between industrial networks and enterprise networks is that industrial networks are typically managed by engineers or technicians. Now engineers are experts at making good product, designing control loops and so on, but they are not IT security wizards. That's the reality, and it means that security products that "just work" reliably and safely with automation systems are going to be more effective in actually delivering security than products that don't.
As we prepare for some time off to enjoy the holiday season, we would like to take a moment to thank you for being a part of our SCADA security community in 2013.
We very much appreciate your readership and the stimulating dialogue that results from it. The Tofino Security team wishes you and your families all the best for a wonderful holiday and a very happy New Year.
Jeff Smith of American Axle & Manufacturing (AAM) is a guru in the world of industrial Ethernet networking and ICS Security. We were fortunate to have him speak again at the 2013 Belden Industrial Ethernet Infrastructure Design Seminar.
