Lack of IoT HVAC control system cyber security and potential real-world impacts

A new IoT valve/actuator from a major HVAC equipment supplier has not only no device security. A further look at the supplier’s catalog shows additional products that communicate using common building insecure communication protocols such as BACnet and Modbus. The ability to remotely control these valves/actuators allows for unauthorized control of a building’s environmental control […]

The Chinese hardware backdoors can cause transformer failures through the load tap changers

As I was reviewing my blogs for a paper I was preparing, I found a nuclear power plant incident involving a station auxiliary transformer load tap changer (LTC) failure. Substation transformers have been acknowledged as the Achilles heel of the electric industry. As a result, the 2015 FAST (Fixing America’s Surface Transportation) Act contained a […]

A critical look at the CSIS Report “Dismissing Cyber Catastrophe”

Jim Lewis is a Sr VP at the Center for Strategic and International Studies (CSIS). He wrote the article “Dismissing Cyber Catastrophe” dated August 17, 2020 – https://www.csis.org/analysis/dismissing-cyber-catastrophe?utm_source=CSIS+All&utm_campaign=e4d5b3e04c-EMAIL_CAMPAIGN_2018_11_08_05_05_COPY_01&utm_medium=email&utm_term=0_f326fc46b6-e4d5b3e04c-221758737 . In ‘Dismissing Cyber Catastrophe,’ Jim argues that concerns about industrial cyber security are overblown and the risk is exaggerated. Because the view that ‘cyber catastrophes’ are […]

Followup: INCOSE Critical Infrastructure Protection and Recovery(CIPR) Conference Call

On Thursday, April 9th, 2020, I gave a presentation to INCOSE Critical Infrastructure Protection and Recovery(CIPR) working group monthly call. With the large attendance, it was evident there was an interesting learning about the critical, but generally not addressed, issues of the engineering aspects of control system cyber security. There was also a common thread […]
