ISO/IEC 15045-3-2:2024 PDF

Overview

ISO/IEC 15045-3-2:2024 - "Information technology - Home Electronic System (HES) gateway - Part 3-2: Privacy, security, and safety - Privacy framework" defines a privacy framework for the HES gateway family of standards. It specifies cybersecurity and privacy considerations to protect premises and personally identifiable information (PPII) exchanged or processed by HES gateway architectures used in homes and single-premise dwellings. The standard builds on the ISO/IEC 15045 series and aligns privacy concepts with ISO/IEC 29100.

Key topics and technical requirements

• Privacy principles: Summary and guidance on consent/choice, purpose legitimacy and specification, collection limitation, data minimization, use/retention/disclosure limitation, accuracy and quality, openness/transparency/notice, and individual participation/access.
• Architecture and actors: Definitions and diagrams for HES gateway components (interface modules, service modules, controller/processor modules), private internal bus communications (CLIP), and parties handling PPII.
• PPII flows and conditioning: Normative rules and permitted data flows between local devices/users, controller service modules, processor service modules, and remote endpoints (detailed in Annex B).
• Conformance and terms: Conformance clauses, normative references, and a glossary of terms and abbreviations for implementers.
• Mapping to existing privacy standards: Informative mapping to ISO/IEC 29100 and guidance on using other privacy standards (Annex A and Annex C).
• Security integration: Cybersecurity requirements to limit access to appropriate HES elements and protect privacy without requiring modification of underlying HAN/WAN protocols.

Practical applications and target users

Who uses ISO/IEC 15045-3-2:

• Smart-home gateway and device manufacturers designing privacy-aware HES gateways
• System integrators and platform architects implementing modular HES architectures
• Security and privacy officers defining compliance and data-handling policies for residential deployments
• Test labs and certification bodies assessing conformance to HES privacy and cybersecurity requirements
• Standards developers and consultants mapping HES privacy to regional data-protection rules

Practical uses:

• Designing gateways that enforce PPII minimization and permitted data flows
• Documenting consent, notice, and access mechanisms for smart-home services
• Integrating privacy controls into controller/processor service modules and CLIP communications
• Demonstrating alignment with international privacy best practices (ISO/IEC 29100)
