Ensuring Compliance with IoT Security Regulations: A Guide for Designers and Developers
May 14, 2024

As the Internet of Things (IoT) continues to expand, securing IoT devices has become a critical priority. Regulatory frameworks worldwide, such as the EU’s Cyber Resilience Act, the UK’s PSTI Act, and Singapore’s Cybersecurity Labeling Scheme, all pivot on common standards like the EN 303 645. For designers and developers, understanding and applying these standards is essential for robust IoT security and regulatory compliance.
Non-compliance with IoT security regulations can lead to severe legal and financial penalties, restricted market access, and reputational damage for device manufacturers. Additionally, it increases vulnerability to cyberattacks and the associated remediation costs, eroding consumer trust and confidence in the product.
Unified Security Protocols Across Global Regulations
But there is also good news. Despite diverse geographical and legislative landscapes, many these regulations have overlapping security mandates which facilitate a unified approach for compliance. Key security features include:
- Effective Vulnerability Management: It's vital to establish systems for users to report vulnerabilities. Prompt patching and updates are necessary to address these vulnerabilities swiftly.
- Regular Software Updates: Devices should automatically update their software, always with user consent, to guard against emergent threats.
Secure Storage of Credentials: All sensitive data, including credentials, should be encrypted and stored securely, ideally within hardware-based key storages to prevent unauthorized access.
- Encrypted Data Transmission: Secure encryption must protect data transmitted by the device, both locally and over the internet, to prevent data breaches.
- Minimized Attack Surfaces: Devices should operate with the fewest possible open ports and limit operational services to essential functionalities to minimize security risks.
Software Integrity Assurance: Security measures like secure boot and code signing should be implemented to ensure that the software has not been altered maliciously.
- Privacy Assurance: Personal data should be handled with utmost security to prevent unauthorized access, unlawful processing, and accidental loss. This usually entails encrypting sensitive data both at rest and in motion based on well-protected encryption keys and mechanisms.
- Elimination of Universal Default Passwords: Devices must ship without generic default passwords, thus requiring users to create unique passwords upon setup. This crucial step mitigates the risks of widespread default password attacks.
Strategic Approaches to Design and Development
Adhering to international security standards requires a proactive security focus throughout the product's lifecycle. Key strategies include:
- Security by Design: Incorporate security considerations during the initial design phase, including threat modeling and the identification and mitigation of potential security vulnerabilities.
- Ongoing Security Assessments: Conduct continuous security evaluations, such as penetration testing and vulnerability scans, preferably by reputable third-party entities to ensure unbiased and thorough findings.
- Adoption of Advanced Technologies: Leverage state-of-the-art technologies like secure enclaves in modern MCUs, enhancing both the security and performance of IoT devices by handling crucial security processes in dedicated hardware.
- Activation of Hardware Security Features: In our labs, we often find that device makers have chosen great chips, but they haven’t activated the security features already present in those chips in their firmware. Make sure your leveraging what you already have for maximum security.
