In this insightful video, I have discussed OT network zoning and conduits as per IEC-62443 standard drawing parallels between the zones within an airport and those within an OT network, shedding light on the importance of effective segmentation. Just as an airport is divided into distinct areas to ensure security and smooth operations, an OT network benefits from zone-based segmentation. The concepts of zones and conduits are discussed and it is explained how monitoring and controlling traffic through firewalls at conduits bolster cybersecurity. This video explores the fundamental strategies behind partitioning an OT network into zones that will equip you with valuable insights to safeguard your industrial infrastructure.
