Cross-Domain Solution A cross-domain solution is a set of security controls that enables data exchange between dissimilar security domains by inspecting, filtering, transforming, or releasing content under explicit policy. The objective is… Concept/Framework Data Diode Data Diode is a hardware or logical boundary that enforces unidirectional data flow between two networks or security domains, allowing data to leave one domain while preventing traffic from returning… Hardware Denied Communications Denied Communications is a communications condition where access is blocked, disrupted, or intentionally prevented. It indicates the link cannot be used normally. Operations Dish Size Dish Size is the physical size of a directional antenna reflector that influences gain, beamwidth, and the ability to capture or transmit signal energy. Hardware Earth Observation Earth Observation is the collection of data about the Earth using remote sensing platforms such as satellites or aircraft to support measurement, mapping, and monitoring. Concept/Framework Earth Segment Earth Segment is the ground-based part of a satellite communications system that includes infrastructure supporting control, telemetry, tracking, and service access from Earth. Hardware Emergency Connectivity Emergency Connectivity is connectivity designed to remain available or rapidly restore communication during emergencies. It supports continuity when normal service is disrupted. Operations Emission Control Emission Control is the management of signal emission level, direction, timing, or pattern to reduce detectability or interference. Operations Encrypted Payload Traffic Encrypted Payload Traffic is payload data that is protected by encryption as it moves across a satellite or communications network. Software Field Communications Field Communications is the communications environment and practice used by personnel operating away from fixed infrastructure to support deployed communications in the field.
