Network Segmentation Network segmentation is the practice of partitioning a network into separate zones so that access, routing, and traffic flow are governed by explicit policy. The goal is to contain risk,… Concept/Framework OPC UA OPC UA is a platform-independent industrial communication standard for secure and structured data exchange between automation systems and devices. It supports interoperability across vendors. Protocol Out Of Band Management Out Of Band Management is administrative access to a system through a separate management path that is independent of the primary production traffic path. It preserves control when the main… Operations Over The Air Rekeying Over The Air Rekeying is the remote update of cryptographic keys across a communications link without requiring manual physical replacement. Operations Packet Capture Packet Capture is the recording of network packets for analysis, troubleshooting, security review, or protocol inspection. It preserves traffic for examination. Operations Permissive Logic Permissive Logic is control logic that confirms conditions are satisfied before allowing an action or sequence to proceed. Operations Physical Isolation Physical isolation is the architectural practice of separating systems or zones so that communication or access requires crossing a deliberate physical boundary. It is used to contain risk, protect critical… Concept/Framework Policy Enforcement Policy Enforcement is the application of rules or controls that ensure users, systems, or traffic follow defined policies. It turns policy into action. Operations Rapid Deployment Terminal Rapid Deployment Terminal is a communications terminal designed to be set up quickly for temporary or emergency use, providing fast-deployed connectivity through minimized installation steps and packaged connectivity equipment. Hardware Regenerative Payload Regenerative Payload is a payload architecture that demodulates, processes, and remodulates signals within the payload before retransmission. Hardware
