Operational technology (OT) networks directly connect systems involved in production and physical operations. Because requirements for availability, safety, and equipment lifecycles differ from standard IT environments, Industrial OT security must be engineered through multi-layered architecture and controlled implementation.
Why OT Security Requires a Tailored Approach
In an OT environment, an uncoordinated configuration change or system reboot could disrupt production lines or cause physical equipment damage.
Multi-Layered Security Architecture
1. Network Segmentation & Cell Isolation: Separating IT and OT networks using industrial firewalls and DMZ zones.
2. Endpoint Protection & Access Control: Enforcing strict role-based authentication and device whitelisting.
3. Continuous Monitoring: Monitoring OT protocols and network traffic to detect anomalies without compromising bandwidth.
