Key Points Improves resilience and survivability of satellite communications systems Can include physical protection, RF hardening, and security measures Used in protected or mission-critical satcom deployments Involves tradeoffs between robustness, resource use, and operational flexibility Addresses vulnerabilities from environmental stress,…
Key Points Physically separates the system from outside networks Reduces exposure to remote intrusion paths Used where strict isolation is required Relies on physical separation rather than logical segmentation Requires manual data transfer procedures and controlled maintenance access Used in…
Key Points Checks whether data integrity has been affected Used before correction or retransmission Common in communication and storage systems Often implemented with parity, checksums, or CRCs Used in communication protocols, storage systems, file formats, and safety-critical data paths Definition…
Key Points Supports remote command beyond direct visibility Used for vehicles, drones, and space systems Relies on relay or long-range communications Enables operations at distances exceeding direct radio or visual range Tradeoffs include greater operational reach versus higher latency Requires…
Key Points Industrial interoperability standard Supports secure structured communication Used in automation and SCADA environments Works across vendors and platforms Provides richer data modeling and security than many older industrial interfaces Definition OPC UA is a platform-independent industrial communication standard…
Key Points Handles service communication policies Supports traffic control and security Used in microservices and cloud-native environments Adds observability to east-west traffic Enforces mTLS, routing, and telemetry policies across service communication paths Definition Service Mesh is an infrastructure layer that…
Key Points Protects payload content from unauthorized reading Used in secure communications and transport Often paired with key management and access control Combines data transport with information security Used in satcom, secure networking, and protected data transport Encryption helps preserve…
Key Points Connects bridge operations with network services Supports navigation, reporting, and data exchange Requires security and segregation controls Preserves safety boundaries and operational integrity Enables data sharing while preventing network interference with bridge-critical functions Definition Bridge to Network Integration…
Key Points Acts as a front door for API traffic Can apply auth, routing, and transformation rules Simplifies client access to multiple backend services Used in distributed application architectures Provides a managed entry point for application traffic Centralizes authentication, authorization,…
Key Points Enforces one-way data movement between domains Used to separate trusted and less trusted security domains Common in critical infrastructure and industrial security environments Prevents reverse flow of data across security boundaries Operates as a hardware or logical enforcement…
