What is ISO/IEC 27400:2022?
ISO/IEC 27400:2022 is an international standard offering cybersecurity and privacy guidelines specifically tailored for Internet of Things (IoT) systems. As IoT devices proliferate across consumer, industrial and smart city domains, security and data protection challenges have become increasingly complex and urgent.
This standard provides high-level principles and practical considerations for stakeholders involved in the lifecycle of IoT systems, including developers, service providers, and regulators. It promotes a secure-by-design approach, focusing on the intersection of cybersecurity risk, privacy-by-design, interoperability, and lifecycle protection.

Scope and Applicability
ISO/IEC 27400:2022 applies to all organizations involved in the design, development, deployment, operation, or decommissioning of IoT systems. The standard is relevant to:
- IoT solution providers
- Device manufacturers and component suppliers
- Cloud service providers and data processors
- Utility and industrial automation vendors
- Smart home and smart city technology firms
It is scalable and can be applied to both small-scale consumer products and complex industrial IoT (IIoT) ecosystems. The guidelines are intended to supplement existing security frameworks like ISO/IEC 27001 by introducing IoT-specific risks and controls.
Certification Process and Procedure of ISO/IEC 27400:2022
- Identify the IoT system scope including endpoints, gateways, cloud services, apps, and networks
- Conduct a comprehensive risk assessment tailored to IoT-specific threats (e.g., physical tampering, firmware attacks, device cloning)
- Define privacy policies and security objectives based on data sensitivity, system functionality, and user expectations
- Develop secure design principles including authentication, access control, data encryption, and software update management
- Create a compliance roadmap and integrate guidelines from ISO/IEC 27400 into your cybersecurity management system
- Document procedures and implement controls for monitoring, incident response, and decommissioning
- Undergo internal or third-party assessments alongside ISO/IEC 27001 or ISO/IEC 27701 for certification support

- Policy Development and Architecture Review: 3–5 weeks
- Technical Control Integration and Documentation: 4–6 weeks
- Final Gap Review and Audit Preparation: 2 weeks
Total estimated time: 10–14 weeks, depending on complexity and stakeholder availability.
What are the Requirements of ISO/IEC 27400:2022?
The standard outlines high-level security and privacy principles for IoT systems:
- Security by Design: Ensure systems are built with inherent safeguards against common threats and can evolve as threats change
- Asset and Data Classification: Identify and label assets and data based on criticality and sensitivity
- Access Management: Implement secure onboarding, user authentication, authorization, and revocation mechanisms
- Secure Communication: Use encryption and secure transport protocols for all data in transit
- Update and Patch Management: Enable secure firmware and software update mechanisms with integrity verification
- Privacy Protection: Embed privacy-by-design principles including data minimization, consent mechanisms, and transparency
- Monitoring and Response: Continuously monitor for security incidents and define incident response workflows
- End-of-Life and Disposal: Ensure secure device decommissioning, including erasure of sensitive data and revocation of credentials
What are the Benefits of ISO/IEC 27400?
- Reduces risk of IoT-specific cyber threats including botnet exploitation, ransomware, and identity theft
- Enhances user and customer trust by demonstrating commitment to cybersecurity and privacy
- Aligns with data protection regulations like GDPR and the California Privacy Rights Act
- Supports secure integration of IoT systems into broader enterprise architecture
- Improves lifecycle management of devices, data, and identity credentials
- Facilitates market access and compliance in regulated sectors (e.g., healthcare, critical infrastructure)
The proliferation of IoT, estimated to surpass 30 billion devices globally by 2030, has made secure and privacy-respecting designs a baseline expectation. Governments and regulators worldwide are issuing stricter guidance and mandates for IoT security, especially in consumer products and industrial applications.
ISO/IEC 27400 fills a critical gap by offering global best practices that can be harmonized with technical controls, laws, and enterprise policies. Adoption is growing among device manufacturers, telcos, utilities, and smart city initiatives as they move toward secure digital ecosystems.
