OT/ICS series

In today’s interconnected world, securing and understanding Operational Technology (OT) and Industrial Control Systems (ICS) is more important than ever. This series of posts explores hands-on lab setups, security best practices, and key learning resources to help you build, test, and protect critical infrastructure. Whether you’re just starting or looking to deepen your expertise, these posts will provide valuable insights into the evolving OT/ICS landscape.

Building OT/ICS Cybersecurity labs

Learn how to build your own OT/ICS cybersecurity lab for hands-on testing, training, and research. This guide covers essential hardware, software, and network setups to simulate real-world industrial environments, helping you develop and refine your security skills in a safe, controlled setting.

Visibility, observability, and segregation in OT/ICS

Visibility and observability are critical for securing and managing industrial OT/ICS environments. Visibility ensures that all assets, communications, and network activities are identified, while observability provides deeper insights into system behaviors, anomalies, and potential threats. Effective segregation of OT/ICS networks using VLANs, firewalls, and air-gapping minimizes the attack surface by isolating critical systems from IT and external networks. This layered approach enhances security, reduces operational risks, and ensures compliance with industry regulations.
