Tale of Two Conferences on protecting critical infrastructure: it was the best of times, it was the worst of times.

Last week I attended two conferences where protection of critical infrastructure were common themes: one focused more on the technical aspects and the other on international security policy. The first was a virtual plenary session of the International Society for Automation (ISA)[1] Committee 99 which is working on updating the standard for Industrial Automation and […]

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 .

Is there a problem with our understanding of the terms IT, OT and ICS when seeking to protect critical infrastructure?

I remember participating in a work group composed of national representatives tasked with coming up with norms for confidence and security building measures (CSBM) for states to follow in cyberspace.  This was quite exciting to be a part of at first, but the discussions slowed down when a representative of a cyber-superpower raised the issue of […]

Zero Trust and ICS

The goal of Zero Trust is getting data securely across network, storage, and computing infrastructure you may not trust. The message is usually between two software entities that are trusted with human beings behind them. But that’s not what happens in an Industrial Control System, such as a DCS or a PLC based plant system. […]

Focus on Integrity

There may be a few people who are puzzled by why I referred to PLC Security as “security.” And this brings me to an often forgotten part of the AIC security triad. Yes, there is Availability.
