Emma Stewart joins Dale to discuss the 3 big OT & ICS security stories from the first quarter. They end by giving their win, fail and prediction for Q1.

In this solosode episode Dale reviews the status of his three predictions from the Q1, 2 and 3 quarter in review episodes and answers a listener question.

Dale is joined by Steve Pozza, CISA Section Chief of Operational Resilience, and Tom Millar, CISA Branch Chief of Resilience, to discuss some of CISA's security services for asset owners. They discuss:

• The Internet accessible attack surface enumeration and vulnerability scanning surface.
• Asset owners can buy products or services to do this. Why is the government doing this?
• What CISA is doing with this attack surface data?
• How is CISA measuring the success of this service offering?
• Other broadly available services and tools, the cybersecurity performance goals (CPG assessment) ~500 done in 2023 (and their thinking about self-assessments), Malcom traffic analysis tool, and a couple of other tools.

Andrew Ginter published his third book this year: Engineering-Grade OT Security. Dale interviews Andrew on the book including:

• Who was the target reader that Andrew wrote the book for?
• Do (should) professional engineers lose their licenses for poor and dangerous cybersecurity design and deployments?
• The use of the term engineering grade, and how he defines it.
• Unhackable protection and safety controls as a major part of engineering grade.
• Unidirectional (one-way) network devices as the only security control listed as engineering grade. Is one-way from the enterprise network to the OT network engineering grade?
• Given the ICSSTRIVE/Waterfall report that 75% of all cyber incidents affecting operations are due to ransomware on IT, should asset owners prioritize address this issue or engineering grade security first?
• What is keeping Andrew working rather than retiring

Main Topics

1. Asset Inventory in Cybersecurity: Dale challenges the common security mantra "You can't protect what you don't know," using examples from both physical and cyber domains. He notes many of the comments on this week's article missed the main point, and he gives hints on the next two asset inventory articles.
2. Legal and Regulatory Issues in Cybersecurity: Dale emphasizes the importance of domain expertise whether it be cybersecurity or the legal profession. He previews upcoming keynote interviews with legal experts and advises cybersecurity professionals against making legal analyses without proper expertise.
3. Artificial Intelligence in Cybersecurity: Dale reveals that most AI submissions for S4 were broad and hand wavy. This isn't wrong, but most have heard this info by now. He then discusses the need for focusing on specific, real-world applications of AI and stresses the importance of measurable improvements in this age of experimentation.
