Cyber Focus: Cybersecurity, National Security, and Critical Infrastructure

Show Notes

America is asking more from its critical infrastructure just as adversaries are finding more ways to target it. AI, data centers, electrification, and next-generation energy systems all depend on operational technology—the control systems that keep power, water, transportation, and industry moving. As that backbone grows more connected, the stakes of securing it grow even higher. In this episode of Cyber Focus, Frank Cilluffo speaks with Zach Tudor, Associate Laboratory Director at Idaho National Laboratory, about how INL tests and secures critical infrastructure at scale. Tudor explains why resilience must guide infrastructure defense, what Ukraine and China reveal about the risks facing critical infrastructure, and why cyber-informed engineering is essential as new technologies move into energy, nuclear, wireless, and industrial systems. The conversation also covers AI's role in control environments, the workforce needed to secure future infrastructure, and the challenge of moving faster before a major event forces action. Main Topics Covered INL's critical infrastructure mission Testing infrastructure at scale OT security and resilience AI risks in control systems Cyber-informed engineering Workforce needs for energy security Key Quotes "No infrastructure is impervious to attack." — Zach Tudor "I think we're getting to the point where, if you are delivering power to the nation, then you are a risk professional as well as a power engineer." — Zach Tudor "Resilience for me is not just the preparation for an attack or the response to an attack, but the ability to mitigate the effects of an attack, to respond quickly, and to recover quickly as well." — Zach Tudor "We are a national lab in the public economic and national security interest. And so we'll do what needs to be done. We say that labs do what others can't, won't or shouldn't do." — Zach Tudor "The mindset of an engineer who's thinking about operations is different from the mindset of an IT security person who's protecting databases or privacy or other data." — Zach Tudor Relevant Links and Resources Idaho National Laboratory Department of Energy National Laboratories Cyber-Informed Engineering (CIE) Guest Bio Zach Tudor is Associate Laboratory Director for National and Homeland Security at Idaho National Laboratory, where he leads programs focused on critical infrastructure protection, operational technology security, and national security innovation.

Can cyber defenses built around human attackers keep pace with AI? Brad Medairy, president of Booz Allen's National Cyber Practice and a McCrary Institute senior fellow, joins Frank Cilluffo to discuss what his team's testing reveals about AI's ability to conduct cyber operations and navigate industrial systems. They examine how these capabilities lower barriers for attackers, why deploying defensive AI requires trust and human accountability, and what executives should do to assess readiness. The conversation also explores active cyber defense and the need to keep essential services running through a compromise. Main topics AI-driven cyber operations Frontier model testing U.S.–China capability gaps Industrial systems at risk AI attack simulations Human oversight and accountability Deception and active defense Operating through compromise Board oversight and readiness Key quotes "Today, with an agentic attack, with an AI-enabled cyber operator that can operate at speed and scale, I think the defender does not have the advantage. It can't move at that pace." — Brad Medairy The way that we've seen models be able to rip apart these [OT] environments, understand the protocols, understand the control system, it's really phenomenal in terms of the capabilities that they provide… the risk to critical infrastructure is at an all-time high." — Brad Medairy "I don't think that we're going to defeat the threat of the future that's so transformative by just automating past operating models and approaches." — Brad Medairy "These adversary capabilities are progressing much faster than cyber defenses. And so you're gonna have to continually assess your environment, continually assess your controls, continually evolve your program." — Brad Medairy "We're inventing new operating models, we're inventing new technologies for cybersecurity. And I think now is our time to really define the future. It's going to take… really working this problem together." — Brad Medairy Resources discussed Booz Allen's Cyber Weapons Index McCrary Institute–Booz Allen joint paper: "AI-enabled threats demand mission-speed resilience – here's how to build it" McCrary Institute–Booz Allen joint paper: "Outpacing AI-enabled cyber threats: A playbook for government CISOs" About the Guest: Brad Medairy is president of Booz Allen's national cyber business, leading the development of defensive and offensive cyber solutions to address America's toughest cyber challenges.

How do you know the person on the other end of a video call is who they claim to be? For Cybersecurity Awareness Month, host Frank Cilluffo welcomes iProov Chief Technology Officer Dominic Forrest to Cyber Focus to discuss how deepfakes are changing fraud, cybersecurity, and digital trust. Forrest demonstrates how a single photograph can be used to impersonate someone on video and explains why awareness alone isn't enough. The conversation examines how impersonation can give attackers access to organizations, what protections employees and consumers need, and how leaders can evaluate defenses. They also explore the challenge of verifying that AI agents are acting with a person's authorization. Main Topics Convincing deepfakes made with free software Why familiar faces and voices aren't proof of identity Verifying identity and genuine presence Fake employees and critical infrastructure access Securing onboarding and account recovery Protecting consumers from impersonation scams Testing and updating deepfake defenses Verifying human authorization for AI agents Key Quotes "I've spent the last 13 years of my life looking at fake faces, and I know today I can't tell the difference between a fake face and a genuine face on a Teams call or on the end of a camera."— Dominic Forrest "But you cannot put this on the consumer. In the same way as in companies, we do not put phishing entirely on the employee." — Dominic Forrest "The test I use is if I was in a street and there was a curtain in front of me, would I hand the money through the curtain if I could not see who was on the far side? Because you cannot trust what it is you can see." — Dominic Forrest "But sometimes at those critical moments, you have to bring it back to the human and say, did this person who I know and I trust authorize this? And is the action that's taking place actually the action that they authorized?" — Dominic Forrest "The test I use is if I was in a street and there was a curtain in front of me, would I hand the money through the curtain if I could not see who was on the far side? Because you cannot trust what it is you can see." — Dominic Forrest Resources Mentioned iProov CEN/TS 18099 Human Agency Protocol About the Guest: Dominic Forrest is responsible for iProov's technology vision, strategy, and roadmap which includes the design and development of its cloud-based infrastructure.

Keeping power, water, and other essential services running requires planning for what happens when cyber defenses fail. On this episode of Cyber Focus, Frank Cilluffo speaks with Stephanie Crowe, head of the Australian Cyber Security Centre, and Nick Andersen, acting director of the Cybersecurity and Infrastructure Security Agency (CISA), about how two close allies are preparing critical infrastructure to operate through compromise. The conversation examines how governments and industry identify their most critical systems, turn shared intelligence into joint action, and prepare for attacks that cross sectors and borders. Crowe and Andersen also discuss how AI is changing cyber defense and what that means for infrastructure investment, workforce skills, and decisions in the boardroom. Main Topics Operating through cyberattacks Protecting critical assets and dependencies China's infrastructure prepositioning CI Fortify and joint industry planning U.S.-Australia and Five Eyes cooperation AI defense and aging infrastructure AI's energy demands Workforce skills and boardroom decisions Key Quotes "You have to be able to fight through compromise now, which is a really different way of thinking about the cyber threat." — Stephanie Crowe "We've come a long way from thinking about our number one cyber risk being data breaches and theft of information into a world where service disruption is now the thing that we have to really consider and plan in our cyber risk management." — Stephanie Crowe "And just to be completely honest, Australia really bailed us out when we were in the middle of our shutdown… Australia led from the front." — Nick Andersen "If the Congress decided that in the next budget that CISA needed to be quintupled in size, we're still not going to have enough resources to be able to meet every single area that we'd like to be able to stray into with our attention." — Nick Andersen "We know that we're seeing exceedingly aggressive, well-orchestrated campaigns, in particular from entities like China, that are engaged in a significant way to preposition across our critical infrastructure to hold it at risk at a time and place of their choosing." — Nick Andersen Links and Resources Cybersecurity and Infrastructure Security Agency (CISA) Australian Cyber Security Centre: Guidance and Resources About the Guests: Stephanie Crowe is Deputy Director-General of the Australian Signals Directorate and Head of the Australian Cyber Security Centre.

As AI expands the capabilities of cyber adversaries, does the federal government have the workforce and tools to keep pace? Rep. James Walkinshaw of Virginia joins Frank Cilluffo to discuss cuts at the Cybersecurity and Infrastructure Security Agency (CISA), their implications for critical infrastructure, and his push for an independent assessment of the agency's capacity. They also examine responsible AI adoption in government, the risks of unauthorized AI tools, and the public anxieties driving opposition to data centers. Walkinshaw outlines efforts to strengthen the federal technology workforce, streamline security approvals, and improve accountability for basic cybersecurity practices. Main Topics CISA staffing and readiness Local cybersecurity support Federal cyber workforce Responsible AI adoption Shadow AI risks Data centers and public trust FedRAMP reform CLEAR Act and event logging Bipartisan cyber leadership Key Quotes "At the precise moment when we most needed CISA to be operating at peak efficiency, it was systematically dismantled." — Rep. James Walkinshaw "When it comes to AI especially, cybersecurity can't be an afterthought. It has to be built in from the very beginning." — Rep. James Walkinshaw "People are starting to see data centers as the physical embodiment of the anxieties we all have around AI." — Rep. James Walkinshaw "If you want to bring progress in AI to a screeching halt overnight, that will happen if something goes really, really bad. If you don't get the safety piece right." — Rep. James Walkinshaw "Federal agencies currently are not even meeting the requirements in terms of event logging. They certainly, for the most part, couldn't answer any of those questions about time to detect or time to mitigate. So our CLEAR Act will require some reporting to Congress around event logging." — Rep.

Can the United States compete with China in AI while managing the risks the technology creates? Host Frank Cilluffo welcomes McCrary Institute senior fellows Bill Evanina and Matt Hayden for a discussion of the difficult choices behind that question. Evanina, who previously led U.S. counterintelligence, and Hayden, a former senior CISA official now at GDIT, assess expectations for the Trump–Xi summit, the limits of cyber cooperation, and the trade-offs behind chip export controls. The conversation also examines Chinese influence efforts surrounding data centers, the importance of energy to AI competition, the stakes of quantum computing, and whether familiar approaches to accountability can work when an AI agent becomes an insider threat. Main topics Trump–Xi summit expectations Volt Typhoon and cyber deterrence Chip exports and technology theft S.–China crisis communications Chinese influence on data center debates AI, energy, and the quantum race AI safeguards and accountability Taiwan and semiconductor dependence Key quotes "We cannot be AI dominant unless we're energy dominant. We can't be. And when you look at AI, it's not AI in its own, it's that it accelerates everything else." ­­— Frank Cilluffo "And so when we look at AI, it's not a matter of having the most advanced models. That helps. But it is a matter of getting that implementation into every corner of industry so that those efficiencies are known and used." — Matt Hayden "The big question is AI— should it be considered an insider threat? And the answer was a resounding yes. But what do we do with insider threats? We try to catch them and prosecute them. Are we going to prosecute an AI agent?" —Bill Evanina "From a pure liability standpoint of who we can blame, there's no AI agent that operates without compute. And so somebody's got to empower this thing at an original sin level." — Matt Hayden "As a metaphor, AI is a supermarket gas station on the highway to quantum. ... Whoever wins quantum, they say wins the world. I think you have to win AI before you win quantum." — Bill Evanina Links and resources CISA: Volt Typhoon and persistent access to U.S. critical infrastructure
