In this episode, Aaron is joined by Paul Shaver, an experienced OT security consultant from Mandiant, part of Google Cloud. Together, they navigate the nuanced landscape of operational technology (OT) cybersecurity.

The episode begins with Aaron recalling a critical incident at a power plant that underscores the potential pitfalls in OT environments. This sets the stage for a rich discussion on the evolution of OT technology, with Aaron and Paul reminiscing about primary domain controllers and early NT workstations.

The conversation shifts to the future of OT in the cloud, where Paul highlights the benefits of cloud solutions, including enhanced resiliency, security, and data optimization through AI. A compelling customer case study illustrates modern technology adoption with web-based HMIs and Chromeboxes.

Paul offers a detailed analysis of the current OT cybersecurity landscape, addressing the persistent legacy system challenges and the need for a cohesive IT-OT security strategy. He discusses the evolving threat landscape influenced by global geopolitical tensions and the rise of zero-day vulnerabilities.

Listeners will gain practical insights into foundational cybersecurity measures, such as network segmentation, asset inventory management, and robust access control..
