IoMTWall：臨床プロトコルディープパケット検査、医療機器異常トラフィック即時遮断、ハードウェア線速フィルタリング

IoMTWall Deep Packet Inspection & Clinical Traffic Enforcement Architecture

Clinical DPI parser, malformed payload blocker, and zero-latency hardware bypass

Central System: Clinical DPI Engine - DICOM / HL7 / SDC Inspector

Clinical IoMT Nodes

• Hospital Core Network Tap
• Protocol-Aware DPI Parser
• Medical Threat Signature Enclave
• Zero-Latency Bypass Switch
• Clinical SIEM / SOC Forwarder

Architectural Layers & Regulatory Standards

• Line-Rate Medical Packet Ingestion (DPDK / eBPF Wire-Speed Packet Filters): Capturing and filtering packets on clinical VLANs without introducing jitter or latency to vital sign telemetry.
• Deep Clinical Protocol Inspection (Stateful DICOM / HL7 / IEEE 11073 Dissectors): Validating that payloads strictly adhere to medical protocol specifications and contain no buffer overflows or malformed command tags.
• Behavioral Anomaly & Exploit Interception (Clinical Machine Learning Baseline Models): Detecting unauthorized commands (e.g., remote firmware write attempts to infusion pumps) and blocking attacks instantly.
• Clinical Alerting & Fail-Open Safety (Fail-Open Optical Hardware Relays): Ensuring that even catastrophic firewall software failure will never interrupt continuous patient telemetry or alarm broadcasts.

Key Metrics: < 8 µs (Packet Inspection Latency) | 10 Gbps (Wire-Speed Medical DPI) | Zero Disruption (Hardware Fail-Open Guarantee) | 100% (DICOM/HL7 Syntax Validation)
