Cyber Brews - Securing the Death Star of Change
Welcome to the Final Episode of the Year—Episode Six!
In this closing episode of 2024, we dive into the critical topic of management of change (MoC) in the context of OT cybersecurity.
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?
Join us as we uncover the complex layers of OT cybersecurity, the importance of thorough risk assessments, and the real-world impacts of implementing robust change management strategies.
Thank you for tuning in throughout 2024. We wish you a Merry Christmas and look forward to bringing you Series 2 of the Cyber Brews Podcast in 2025, with even more exciting episodes planned!

In this episode, we dive into the critical topic of Risk and Consequence in the context of OT cybersecurity. Here, we share our insights on cyber risks and the potential consequences organisations face.
In This Episode, We Cover:
Risk Assessment Basics: We discuss the foundations of cyber risk assessments, focusing on identifying deviations from normal operations and exploring key concepts like "attack vectors" and the "kill chain."
Example Incident: We examine the CrowdStrike case to understand how OT risk assessments account for insider threats and unintended consequences.
Likelihood and Attack Types: We look at the frequency and variety of cyber threats, considering how risk changes based on the type of attacker, from disgruntled employees to bot-driven attacks.
Mitigation Strategies: We wrap up with a look at prevention versus mitigation, discussing ways to prioritize actions and implement these countermeasures despite the challenge of quantifying cyber risks.
Join us in exploring the complex layers of OT cybersecurity risk assessments and the real-world impacts of these measures.
Thank you for tuning in, and don’t forget to rate our podcast as we continue our journey through the world of OT cybersecurity!
