    Cyber Brews - IEC-62443 Security Levels, Simplified?

    Series 2 – Episode 5! Cyber Brews: IEC-62443 Security Levels, Simplified?This month’s brew tackles the industrial cybersecurity standard that everyone talks about — but few really get: IEC 62443. If you’ve ever felt lost in a sea of FRs, SRs, and SLs, you’re not alone. We’re here to break it down, coffee (or pint) in hand. In this episode, we unpack the core components of IEC 62443 — from Foundational Requirements (FRs) to Security Levels (SLs) — and explore what they actually mean for real-world OT environments. Key topics on tap include: What the different Security Levels (SL1 to SL4) actually represent — and why SL4 isn’t always the goalThe role of Foundational Requirements (FRs) and how they structure your cybersecurity baselineHow System Requirements (SRs) map to practical controls in the field Why context matters: understanding your risk, your environment, and your realistic target level So whether you’re just getting into IEC 62443 or trying to explain it to someone else without inducing a yawn, this episode’s for you. Grab your brew of choice and join us as we demystify the standard — one security level at a time.

    Cyber Brews - Trust No One, Verify Everything (Zero Trust)

    Series 2 – Episode 4! Cyber Brews: Trust No One, Verify Everything (Zero Trust) This month’s brew dives into a game-changing security model that’s making waves in both IT and OT: Zero Trust. Forget the old perimeter mindset — in this episode, we explore why trust is no longer a security strategy, especially when it comes to protecting critical industrial systems. We kick off with a breakdown of what Zero Trust actually means, where it came from, and why it’s become essential in the world of Operational Technology. As OT and IT networks continue to converge, the traditional “trust but verify” approach just doesn’t cut it anymore. Key topics on the table include: Why OT environments need Zero Trust now more than ever. How to apply Role-Based Access Control, Network Segmentation, MFA, and Continuous Monitoring in industrial settings. The real-world benefits of Zero Trust: from reduced insider threats to better compliance and resilience. Common challenges and how to start making progress, even in complex legacy environments. So grab your favourite brew and join us as we unravel how Zero Trust could secure the future of OT — one segment, one policy, one verified connection at a time.

We kick things off with a look at the iconic failure of the Empire's Death Star and explore how its downfall can teach us valuable lessons for managing change in operational technology environments. In this Episode we cover: The Death Star Example: A discussion of one of the most iconic and catastrophic management of change (MoC) failures, analysing how overlooked risks and gaps in planning led to its downfall—and what lessons we can apply to cyber security today. MoC Assessment Basics: Exploring the foundational elements of a robust MoC process, including conducting thorough risk assessments, maintaining accurate and up-to-date documentation, and identifying critical records essential to cyber security. Supply Chain Risk: Understanding the risks posed by vendor-supplied default configurations—do you really know what’s in them? Examining how changes in the supply chain may impact current physical security controls and whether those changes could alter the criticality of your operations. Employee Training: Highlighting the importance of employee education and preparedness in the MoC process. How do training programs ensure staff adapt to and manage changes effectively while maintaining a strong security posture?
