Use ETSI TS 103 701 concepts (roles, ICS/IXIT, test groups and test cases) to structure your assessment, even if you are not pursuing formal certification. Standards compliance fails when teams treat it as a document exercise. ETSI EN 303 645 compliance is an engineering system: controls in product + services, tests that prove those controls work, and evidence that stays current as you ship updates and handle vulnerabilities. This page focuses on how to structure that system using ETSI's conformance assessment framing. ## What 'compliance' means for ETSI EN 303 645 ETSI EN 303 645 is a baseline consumer IoT security standard. In practice, teams use it to define minimum product security controls and to demonstrate due care to internal stakeholders, customers, procurement teams, and auditors. A strong compliance outcome is not a checklist. It is a traceable line from provision -> control -> verification -> evidence -> ongoing operation (patching, monitoring, incident response). - Define scope: device, firmware, mobile app, cloud services, and associated services - Turn each provision into testable acceptance criteria and an evidence artifact - Operate the controls continuously: updates, vulnerability handling, logging, and review cadence *Recommended next step* *Placement: after the compliance steps* ## Turn ETSI EN 303 645 Compliance into an operational assessment Assessment Autopilot can take ETSI EN 303 645 Compliance from operationalizing the guidance into a tracked program to a reusable workflow inside Sorena. Teams working on ETSI EN 303 645 can keep owners, evidence, and next steps aligned without copying this guide into separate documents. - [Open Assessment Autopilot for ETSI EN 303 645 Compliance](/solutions/assessment.md): Start from ETSI EN 303 645 Compliance and turn the guidance into owned tasks, evidence requests, and review checkpoints. - [Talk through ETSI EN 303 645](/contact.md): Review your current process, evidence gaps, and next steps for ETSI EN 303 645 Compliance. ## Conformance assessment mindset (ETSI TS 103 701) ETSI TS 103 701 is a conformance assessment specification for baseline requirements of ETSI EN 303 645. It frames assessment around roles (e.g., Device Under Test, Supplier Organization, Test Laboratory), an assessment procedure, and structured documentation used to derive test plans. Even if you're doing first-party self-assessment, the same structure helps: you build a repeatable test plan, capture verdicts, and keep evidence consistent across versions and SKUs. - Treat your product as a Device Under Test (DUT) with a defined assessment environment - Maintain supplier/implementer declarations and extra info that drives test planning - Keep verdicts and findings tied to specific provisions and releases ## Build an ICS/IXIT-style evidence architecture ETSI TS 103 701 describes the use of an Implementation Conformance Statement (ICS) and Implementation eXtra Information for Testing (IXIT). The key idea: record what is implemented, plus the extra technical details a tester needs to assess it. Translate that into a practical product security evidence system: a structured 'what we implement' statement plus technical evidence that proves it. - ICS-like: per-provision claim statements, supported/unsupported features, and versioned scope - IXIT-like: interface inventory, update mechanism details, crypto and key-handling details, deletion/reset behavior - Evidence links: threat models, test plans, test results, release notes, and vulnerability handling records ## Conceptual vs functional verification (make it audit-proof) ETSI TS 103 701 distinguishes two common verification modes: conceptual checks (evidence of design and declared behavior) and functional checks (observable behavior under test). For high-confidence compliance, pair them: conceptual evidence shows intent and implementation approach; functional tests show the product actually behaves as claimed. - Conceptual: policies, architecture decisions, interface specs, update trust chain design, logs configuration - Functional: device-level tests (auth behavior, interface exposure, update verification, reset/delete) and service tests (VDP workflow, notifications, telemetry anomaly handling) - Regression: re-run critical security tests per release and keep historical results ## Use external evidence without weakening assurance ETSI TS 103 701 describes how external evidence can be used instead of performing certain test groups, when appropriate. This is powerful but risky if you accept 'paper' evidence that doesn't reflect reality. Use external evidence only when it is current, attributable, and clearly scoped to the exact version and configuration you ship. - Accept only evidence that is versioned and traceable to shipped builds and configurations - Prefer machine-verifiable artifacts: signed SBOM, build attestations, CI logs, and reproducible test runs - Document gaps and compensating controls when a provision is not applicable or not fully implemented ## Minimum evidence pack (what auditors and customers ask for) Build an evidence pack that answers the same questions repeatedly: what is implemented, how it is verified, and how it is operated over time (updates and vulnerability management). Keep it light, but complete: it should be easy to update every release and easy to share with procurement or internal security assurance teams. - VDP and CVD workflow evidence: contact channel, acknowledgement + status timelines, triage records, fix and disclosure records - Secure update evidence: signing/verification approach, anti-rollback approach, update rollout plan, update failure handling - Interface hardening evidence: disabled services list, debug lockdown evidence, unauthenticated info disclosure checks - Data lifecycle evidence: reset/delete behavior, user instructions, confirmation flows for associated services ## Common compliance pitfalls (and how to avoid them) Most ETSI EN 303 645 'failures' are not about intent; they're about operational reality. Teams document policies but can't produce proof at release time. Avoid fragile compliance by tying provisions to release gates and by keeping evidence generated automatically where possible. - Shipping an update mechanism without robust authenticity/integrity verification and anti-rollback - Publishing a VDP without running it (no triage, no status updates, no closure records) - Treating cloud services and mobile apps as 'out of scope' even when they are required to operate the device securely - Keeping evidence as static documents instead of versioned artifacts tied to builds ## Primary sources - [ETSI EN 303 645 V3.1.3 (Official PDF via ETSI Deliver)](https://www.etsi.org/deliver/etsi_en/303600_303699/303645/03.01.03_60/en_303645v030103p.pdf?ref=sorena.io) - Primary source for the current baseline security provisions in V3.1.3 (2024-09). - [ETSI TS 103 701 V2.1.1 (Conformance Assessment) (Official PDF via ETSI Deliver)](https://www.etsi.org/deliver/etsi_ts/103700_103799/103701/02.01.01_60/ts_103701v020101p.pdf?ref=sorena.io) - Defines conformance assessment methodology and test scenarios structure (including ICS/IXIT concepts). - [ETSI IPR Database](https://ipr.etsi.org/?ref=sorena.io) - Use for due diligence when adopting ETSI deliverables in product programs and contractual statements. ## Related Topic Guides - [ETSI EN 303 645 FAQ (Consumer IoT Security Standard)](/artifacts/global/etsi-en-303-645/faq.md): Answering common product-team questions about ETSI EN 303 645: unique passwords, vulnerability disclosure policy requirements, secure software updates. - [ETSI EN 303 645 Requirements (Provision Map 5.1-5.13)](/artifacts/global/etsi-en-303-645/requirements.md): Provision-by-provision ETSI EN 303 645 requirements for consumer IoT: passwords, vulnerability disclosure policy, secure software updates, secure storage. - [ETSI EN 303 645 Secure Updates & Vulnerability Disclosure (VDP + CVD)](/artifacts/global/etsi-en-303-645/secure-update-and-vulnerability-disclosure.md): Deep implementation guide for ETSI EN 303 645 update security and vulnerability disclosure: publish a VDP, run coordinated vulnerability disclosure (CVD). - [ETSI EN 303 645 vs UK PSTI (Practical Mapping for Connectable Products)](/artifacts/global/etsi-en-303-645/etsi-en-303-645-vs-uk-psti.md): Practical comparison of ETSI EN 303 645 baseline consumer IoT security provisions vs the UK PSTI security requirements regime. --- [Privacy Policy](https://www.sorena.io/privacy) | [Terms of Use](https://www.sorena.io/terms-of-use) | [DMCA](https://www.sorena.io/dmca) | [About Us](https://www.sorena.io/about-us) (c) 2026 Sorena AB (559573-7338).
