Key Points Requires bounded response times Used in automation and embedded systems Timing correctness is part of functional correctness Common in industrial and motion control Emphasizes deterministic timing rather than only raw processing speed Definition Real Time Control is control…
Key Points Routes traffic by policy rules rather than destination lookup alone Can override default routing decisions Used in enterprise and carrier networks Supports application or source-based path selection Provides intentional traffic steering when standard routing is insufficient Definition Policy…
Key Points Splits duties across provider and customer Used in cloud security and operations Clarifies who manages which control Applies differently by service model Responsibility boundaries depend on service model (IaaS, PaaS, SaaS) Requires clear documentation to avoid security gaps…
Key Points Follows identity verification in access flows Controls permissions and resource access Used in digital, network, and physical systems Often paired with authentication Evaluates permissions after identity has been established Definition Authorization is the process of determining what an…
Key Points Provides backup functionality Supports continuity during failures Often paired with switching or cross-strapping Used in spacecraft, industrial systems, and critical infrastructure Operationally effective through automatic or manual takeover Definition Redundant Subsystem is a backup or duplicate subsystem that…
Key Points Protects cloud resources and data Includes identity, configuration, and monitoring controls Depends on shared responsibility boundaries Used in public, private, and hybrid cloud Spans identity, encryption, configuration, monitoring, and policy management Definition Cloud Security is the set of…
Key Points Refers to electromagnetic frequency range Core resource in wireless and satellite systems Subject to allocation and interference management Different bands have different propagation properties Finite and shared across multiple services Definition Spectrum is the range of electromagnetic frequencies…
Key Points Uses more than one gateway path or site Improves resilience and service continuity Relevant in satellite and network architectures Reduces single-point gateway dependency Requires path independence and failure domain analysis Definition Gateway Diversity is the use of multiple…
Key Points Describes write throughput capacity of a historian system Must match or exceed sensor, tag, and event volume produced by operational systems Affects visibility freshness, data loss, backlog growth, and storage saturation Constrained by tag count, sample frequency, network…
Key Points Carries traffic in the forward direction from infrastructure to endpoint Important in satellite and access networks Often called the downlink from network to user perspective Service delivery often depends on robust forward link performance Operates across satellite communications,…
