CSH EV SHIELD — EV Charging & Read-Only OCPP Posture (English (UK))

Architecture & Capabilities

Built for teams who need proof, not promises

Read-only CSMS / OCPP telemetry

Connects to authorised Charge Station Management Systems via read-only OCPP 1.6J Security Profile 3 and OCPP 2.0.1 feeds.

ISO 15118 & mTLS certificate lifecycle

Tracks EVSE leaf certificates, TLS security profiles and impending expiry across depot and public charging fleets.

Firmware provenance metadata

Monitors ISO 24089 / OCPP signed firmware update verification events and configuration drift.

Evidence-based outage correlation

Correlates charger outages with OCPP security events without falsely classifying utility grid faults as cyberattacks.

Hard block on physical actuation

Policy EV-SAFE-001 blocks RemoteStopTransaction, current modification, contactor toggles and vehicle ECU/CAN commands with HTTP 403.

ISO/SAE 21434 & UNECE R155/R156 awareness

Supports operator readiness documentation without claiming accredited vehicle type approval.

Visual Architecture

Read-Only OCPP 1.6J/2.0.1 Charging Security

Fleetwide ISO 15118 mTLS certificate lifecycle tracking and outage correlation with zero physical contactor actuation.

Visual Architecture

Transport Threat Telemetry & SOC Triage

Specialist EV charging anomaly detection correlated with live regional power telemetry.

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 UK NCSC Cyber Essentials Plus, UK GDPR & Data Protection Act 2018, ISO/IEC 27001:2022.
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.

Frequently asked questions

Does the AI ever take action on its own?

No. Detection is driven by deterministic rules. ARYA SAI only produces advisory summaries from redacted evidence, and every containment action requires a named human approver.

Where is our data stored?

You choose UK (London) or EU (Frankfurt) residency at onboarding. Additional regions are available on Enterprise plans.

Are you certified for ISO 27001 or Cyber Essentials?

CSH Compliance helps you prepare evidence for these schemes. We do not claim certifications we have not been awarded; our own certification status is published on the Trust page.

Can we scan any domain or IP address?

Only assets you have verified ownership of via DNS or HTTP token. Unverified assets cannot be scanned or ingested.

Do you work with managed service providers?

Yes. The partner edition supports delegated tenants, pooled licensing and partner billing.
