Series 3 - Episode 3!

Artificial Intelligence is rapidly becoming part of the industrial cyber landscape but is it strengthening critical infrastructure, or introducing entirely new risks?

In this episode we explore the growing relationship between AI and OT security, discussing how organisations are beginning to rely on AI-driven technologies within critical infrastructure environments.

We dive into topics including:▪️ AI as a new dependency in critical infrastructure▪️ AI-assisted defence for OT environments▪️ How attackers are beginning to use AI against operational technology▪️ The emerging cyber “arms race” between defenders and adversaries▪️ New vulnerabilities and attack vectors introduced by AI systems▪️ Risks such as malicious data poisoning and the growing concern around AI model collapse caused by AI-generated training data

As AI adoption accelerates, understanding both the opportunities and the unintended consequences becomes increasingly important for organisations operating industrial systems.

So grab a brew and join us as we explore whether AI is becoming the future of industrial cybersecurity or the next major challenge.

Series 3 - Episode 2!

The landscape of industrial cybersecurity guidance in the UK is evolving, and many organisations are now navigating the transition from HSE’s OG86 guidance to the more comprehensive IEC 62443 standard.

In this episode of Cyber Brews, we explore what that shift really means for engineers, operators, and organisations responsible for industrial control systems and operational technology.

We discuss why OG86 existed, the role it played in protecting safety-related systems, and how the growing cyber threat landscape has driven the move toward IEC 62443’s broader, lifecycle-based approach to cybersecurity.

Along the way, we unpack key differences between the two approaches, the expectations emerging from regulators, and some of the practical challenges organisations face when applying these concepts to real-world OT environments.

So grab a brew and join us as we break down the journey from OG86 to IEC 62443 and what it means for the future of industrial cyber security!

Series 3 – Episode 1!2025 has been a year full of remarkable OT cybersecurity stories, and in this episode of Cyber Brews, we take you behind the scenes of the most impactful events in the industrial cyber world.

From Jaguar Land Rover incidents to human-factor challenges in incident response planning, AI ransomware and defence-in-depth strategies, zero-day threats, and attackers embedding infostealers in PyPI packages, we cover the stories that shaped the year.

We also discuss the wider regulatory and geopolitical landscape, including the Cyber Security and Resilience (Network and Information Systems) Bill, CISA alerts, FBI advisories, and global collaboration to defend critical infrastructure against pro-Russia hacktivist threats.

Join us as we unpack the lessons learned from 2025, explore the evolving threat landscape, and highlight what it takes to protect critical industrial systems in a world where cyber risks are ever-present.

So grab a brew and tune in to the front lines of OT cybersecurity.

Series 2 - Episode 8

CAF 4.0 – What’s Changed Since CAF 3.2?

In this episode of Cyber Brews, we take a closer look at Cyber Assessment Framework (CAF) version 4 and explore how it differs from CAF 3.2.

We talk through the key changes, what they mean in practice for organisations operating in ICS and OT environments, and how teams should start thinking about alignment, evidence, and assurance under the updated framework.

Whether you’re already working with CAF or preparing for future assessments, this episode helps break down what’s new, what’s evolved, and what really matters moving forward.

So grab a brew and join us as we navigate the latest changes in the CAF landscape.

’Twas the night before Patch-mas, when all through the plant,
Not a system was stirring… or so we all thought.

In this Cyber Brews Christmas Special, we put a cyber security spin on the classic ’Twas the Night Before Christmas tale. This festive episode tells a story from the world of ICS and OT security, where late-night alerts, unpatched systems, and seasonal good intentions collide.

With humour, rhyme, and a touch of cyber realism, ’Twas the Night Before Patch-mas is a light-hearted reminder of why patching, preparation, and a bit of caution still matter — even during the holidays.

Grab a brew of hot chocolate, settle in, and enjoy a festive cyber tale.

Series 2 – Episode 7!When something goes wrong in the OT world, every second counts....but whatever happens, don’t panic.

This months episode we take a look into incident response and recovery plans. We break down the essentials of Incident Response in Operational Technology environments — what it is, who needs to know about it, and why it matters — towel is optional.

We discuss what makes a strong Incident Response Plan (IRP), the key components every organisation should include, and how even well-prepared plans can fail when theory meets reality.

Along the way, we share real examples and lessons learned from the front lines of OT security and we talk a little about our latest published cyber security paper on using critical task analysis to understand the human element of incident response plans.

So grab a brew, keep calm, and join us as we hitchhike through the world of OT incident response.

Something sinister is stirring in the systems…

In this Cyber Brews Halloween Special, we dive into the true story behind one of the most chilling cyber incidents in industrial history the Triton malware attack.

What began as a routine night in a control room turned into a digital nightmare, when rogue code infiltrated safety systems designed to prevent catastrophic industrial accidents.

With a Halloween twist, “Ghost in the Control Room” explores how a few hidden lines of code nearly turned a secure facility into a scene of chaos — and what this haunting real-world case teaches us about human error, resilience, and the invisible forces moving through our networks.

So grab your favourite brew, turn down the lights and settle in for a Halloween Special.

Series 2 – Episode 6!

This month’s brew takes a fresh look at the latest updates in IEC 62443-2-2:2025 — The standard that sets out requirements for industrial automation and control system security programs.

If that sounds a bit dry, don’t worry — we’re serving it up in plain English, with a dash of Dave & Chris -style "banter".

In this episode, we break down what’s new in the revised standard, why it matters, and how these changes impact organizations looking to strengthen their OT security posture.

Key topics on tap this month include:

• What IEC 62443-2-2 actually covers and why it’s important

• The most significant changes in the latest update
  
• How these updates affect compliance and real-world implementation
  

So grab your favourite brew and join us as we try to make sense of the updates in the new IEC 62443-2-2:2025 — hopefully without the headache.
