CSH HOME SHIELD — Smart Home & Consumer IoT Posture (Français (FR))

Architecture & Capabilities

Pour les équipes qui exigent des preuves

Explicit homeowner consent

Requires verified household ownership and privacy notice acceptance before any passive LAN discovery runs.

Passive LAN discovery

Observes DHCP, ARP, mDNS, SSDP and Matter/Thread metadata via optional Linux/OpenWrt gateway or authorised router API.

Confidence-scored fingerprinting

Matches vendor, model and firmware EOL lifecycle with explicit confidence scores (0.0–1.0).

Unsupported = 'unknown' (never 'secure')

Unrecognised devices are strictly labelled 'unknown' rather than giving false assurances of security.

Zero media or lock-code collection

Strictly rejects camera RTSP video streams, microphone audio, smart lock PIN codes and plaintext Wi-Fi passwords.

Offline gateway resilience

Optional home gateway buffers metadata locally if cloud connectivity drops and verifies Ed25519-signed firmware updates.

Visual Architecture

Consent-Gated Household LAN Discovery

Passive metadata collection across DHCP, mDNS and Matter with strict privacy filtering rejecting all camera RTSP streams and audio.

Visual Architecture

Hardware Lifecycle & Confidence Scoring

Transparent posture classification where unsupported devices are labelled 'unknown' instead of giving false security.

Deterministic Technical Controls & Machine-Verifiable Evidence

OpenAPI 3.1 Contract Trust & PQC Center

1. Detection Engine (CSH Sentinel): Git-versioned Sigma rules (CSH-RULE-001..004) mapped to MITRE ATT&CK (T1110.001, T1098.003, T1048, T1190) with idempotent dedupe_key ingestion and SHA-256 immutable event hashes.
2. AI & MCP Firewall (CSH AI Guard): Pre-inference DLP scrubbing ([REDACTED_SECRET], [REDACTED_PII]), explicit per-agent Model Context Protocol (MCP) tool allowlists, and indirect prompt-injection blocking.
3. Database Isolation (PostgreSQL 16): Enforces ENABLE / FORCE ROW LEVEL SECURITY across all 20 tenant tables bound to transaction-local current_tenant_id(); cross-tenant queries fail closed with HTTP 403.
4. Human-Gated Containment: Zero autonomous destructive actions. Host isolation (isolate_host) and credential revocation require named human step-up approval recorded in an append-only audit trail.
5. Verified Exposure & GRC (CSH Scan): Cryptographic DNS TXT or HTTP ownership token required before scanning. Continuous evidence aligned with ANSSI Guides d'hygiène informatique, Directive NIS2 France, RGPD / CNIL.
6. Post-Quantum Roadmap (CSH Quantum): Cryptographic inventory tracking RSA/ECDSA/TLS keys against UK NCSC 2028 discovery, 2031 priority migration (ML-KEM / ML-DSA), and 2035 full PQC completion.

Defense-in-Depth Isolation

Database-enforced tenant boundaries & UK NCSC PQC alignment.

PostgreSQL 16 FORCE ROW LEVEL SECURITY on all 20 tenant tables.
Pre-inference DLP secret and PII scrubbing before any advisory call reaches ARYA SAI.
Aligned with UK NCSC 2028 / 2031 / 2035 Post-Quantum Cryptography milestones.

Questions fréquentes

L'IA prend-elle des mesures de confinement seule ?

Non. La détection repose sur des règles déterministes. ARYA SAI produit uniquement des synthèses consultatives à partir de preuves expurgées ; chaque action exige une validation humaine.

Où nos données sont-elles hébergées ?

Vous choisissez l'UE (Francfort) ou le Royaume-Uni (Londres) lors de l'intégration.

Accompagnez-vous la conformité NIS2, RGPD et ISO 27001 ?

Oui, CSH Compliance relie automatiquement les preuves techniques aux contrôles ISO/IEC 27001:2022, NIS2 et RGPD.

Pouvons-nous scanner n'importe quel domaine ?

Uniquement les actifs dont vous avez prouvé la propriété par jeton DNS TXT ou HTTP.

Travaillez-vous avec les fournisseurs de services gérés (MSP) ?

Oui, avec gestion déléguée des locataires et licences mutualisées.
