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 7 A step back in time to 11 December 2005. 06:01 in the morning. A series of explosions at the Buncefield oil storage depot near Hemel Hempstead shook the surrounding area. The blast could be heard up to 125 miles away and registered 2.4 on the Richter scale. In this episode of Cyber Brews, we explore the three questions posed by the UK Competent Authority following the Buncefield incident and consider how they can help organisations rethink their approach to cybersecurity: 🔹 Do we understand what can go wrong? 🔹 Do we know what systems are in place to prevent this happening? 🔹 Do we have information to assure ourselves that they are working effectively? These questions may sound straightforward, but they raise some important challenges for organisations responsible for critical infrastructure. We discuss how they apply to OT cyber risk assessments, security controls, organisational accountability and the evidence needed to demonstrate that cybersecurity measures are actually working. Because having firewalls, procedures and security policies in place is one thing. Understanding what could go wrong, knowing whether the right protections exist, and having evidence that they remain effective is another. Whether you're an OT engineer, cybersecurity professional, site owner or process safety specialist, join us as we explore how lessons from Buncefield can help us ask better questions about industrial cybersecurity. ☕ Grab a brew and join the conversation. Are we asking the right questions about OT cyber risk?
What does a French military fortification from the 1930s have to teach us about OT cybersecurity? Quite a lot, actually.
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.
