A multi-layer intrusion detection system combining physical-layer waveform analysis, deterministic protocol inspection, and AI-driven behavioral baselining — deployable across military, aerospace, maritime, industrial, and space platforms.
Platform Architecture
BusArmor operates simultaneously at every layer of the data bus — from raw electrical waveforms at the wire to a cognitive behavioral layer that introduces time, context, and pattern intelligence — all within a transmit-inhibited passive architecture that never touches mission-critical controls.
Physical Layer
Waveform Inspection & Hardware Fingerprinting
Every signal on the bus analyzed at the electrical level — hardware tampering, rogue device insertion, and impedance anomalies identified directly from the waveform.
Wire-Level Threat Detection
Wire-Level Threat Detection
Every device on the bus carries a unique electrical fingerprint — subtle characteristics in its analog waveform that no firmware can replicate. BusArmor profiles and baselines these signatures in hardware, flagging rogue insertions, counterfeit transceivers, and physical tampering the moment the electrical identity deviates from the enrolled baseline.
Signal Domain Transformation & Validation
Signal Domain Transformation & Validation
Raw time-domain waveforms are transformed into the frequency domain and subjected to both deterministic algorithms and statistical anomaly thresholds. This dual-domain analysis isolates micro-reflections, impedance shifts, and injected spectral noise that remain invisible to any purely time-domain or protocol-layer inspection.
Protocol & Intelligence Layer
Deterministic IDS Rule Engine
Frame content, timing sequences, and protocol state boundaries inspected against a strict rule set — command injection, out-of-range parameters, and sequence violations classified with no ambiguity.
Multi-Protocol Coverage
Multi-Protocol Coverage
Simultaneously monitors and decodes any mix of safety-critical serial buses and custom communication architectures, applying platform-specific rule sets and physical profiles to the exact network topology.
Message-Level Rule Engine
Message-Level Rule Engine
Frame content, timing sequences, and protocol state boundaries inspected against a strict rule set. Command injection, out-of-range parameters, and sequence violations classified with no ambiguity.
AI-Augmented Anomaly Detection
AI-Augmented Anomaly Detection
A machine learning layer adapting to the platform's live operational baseline to surface statistical deviations and zero-day patterns that static rules cannot anticipate.
Cognitive Behavioral Layer
Cognitive Defense Hub
The brain of the system — processing high-fidelity multi-layer data, cross-referencing with historical patterns, and flagging deviations with high precision.
Dynamic Operational Baselining
Dynamic Operational Baselining
Continuously ingests multi-layer data to establish and maintain a precise behavioral baseline — capturing exactly how the system operates under normal mission parameters.
Continuous Threat Model Refinement
Continuous Threat Model Refinement
Constantly updates threat models against the established baseline — detecting subtle, distributed anomalies and zero-day exploits that traditional signature-based systems would miss.
Cross-Layer Data Correlation
Cross-Layer Data Correlation
Synthesizes disparate clues across all layers — correlating a physical voltage fluctuation with an application-layer message pattern to identify sophisticated, multi-stage attacks.
System Configuration
Every BusArmor deployment is scoped together with the customer — protocol mix, channel count, and deployment topology are defined to match the target platform.
Protocol Configuration
Protocol Selection
Customer-defined — any serial data bus, including fully custom protocols. IDS rule sets and physical-layer profiles are developed specific to the target communication architecture.
Channels per Bus
1 to N simultaneous channels per bus type; dual-redundant paired channels supported
Simultaneous Capture
All selected channels monitored in parallel — no time-slicing, full-take passive capture on every channel
Deployment Topology
Placement Options
Co-located with bus controller · distributed at LRU or subsystem level · centralized platform security node
Physical Form Factor
Ruggedized embedded module, fully fanless passive cooling — deployable in space-constrained installations
Environmental Rating
Designed to MIL-STD, DO-160, and ECSS requirements for vibration, temperature extremes, shock, and EMI
