Overview
ISO/IEC 27403:2024 - Cybersecurity – IoT security and privacy – Guidelines for IoT-domotics provides structured guidance to analyse security and privacy risks and to identify controls for Internet of Things (IoT) domotics (home automation) systems. Published by ISO/IEC JTC 1/SC 27, the standard adapts general IoT cybersecurity and privacy principles to the specific features of domotics - including non‑expert users, ad‑hoc architectures and long supply chains - and promotes practical, life‑cycle oriented risk management.
Key topics and technical scope
The standard covers the following high‑level areas and technical topics:
- Risk assessment for IoT‑domotics systems, including sources of security and privacy risk across:
- service sub‑systems, gateways, devices/physical entities and networks
- Reference model and life cycles for domotics deployments to map threats and controls by stage
- Security and privacy dimensions tailored to home automation scenarios
- Security controls and best practices such as:
- security policy and organizational measures, asset management, secure disposal
- secure system engineering, secure development environments, verification and testing
- monitoring, logging and log protection; device and user authentication
- software/firmware update provisioning, vulnerability sharing, supplier relationship management
- management of vulnerable devices and lifecycle‑specific security measures
- Privacy controls, including:
- privacy by default, notice and transparent communication of privacy preferences
- minimization of data collection, unlinkability of personal data, accountability measures
- unique device identity, fail‑safe authentication, verification of automated decisions
- Principles and user considerations such as easy security settings for non‑expert users, child protection, and scenario‑specific privacy preferences
- Informative annexes with use cases, stakeholder concerns, responsibilities and device‑specific measures
Practical applications
ISO/IEC 27403:2024 is designed to be applied to:
- Risk assessments and security reviews of home automation products and services
- System and solution design for IoT‑domotics gateways, devices and cloud services
- Procurement and supplier management to ensure secure lifecycle practices
- Creating user‑facing security/privacy defaults and guidance for non‑expert consumers
- Incident response, vulnerability disclosure and maintenance procedures for domotics ecosystems
Who should use this standard
Primary audiences named in the standard:
- IoT‑domotics service providers and service developers
- Organizations or assessors who supervise, verify or certify domotics security and privacy
Other stakeholders who will benefit include device manufacturers, integrators, system architects, security testers and privacy officers working in smart home/automation ecosystems.
