Cybersecurity in IoT & EMC Workshop by Wurth Elektronik & MotionLab.Berlin

Key Takeaways & Insights

I recently attended an insightful workshop hosted by Wurth Elektronik and MotionLab.Berlin, which focused on Cybersecurity in IoT and Electromagnetic Compatibility (EMC). As cybersecurity researchers and students, we recognize the increasing importance of securing IoT devices in today's interconnected world. Here’s a breakdown of the key points discussed:

1. Why Cybersecurity in IoT Matters

Rising Cybercrime: Cybercrime is escalating, with losses projected to reach trillions by 2025.
Real-World Breaches: IoT-enabled devices are increasingly being used to compromise networks, highlighting the importance of embedding robust security from the outset.

2. Designing Secure Embedded Systems

Key strategies for creating secure IoT systems:

Secure Boot & Storage
Encrypted Communication
Over-the-Air (OTA) Updates The goal is to implement a security framework that balances performance and protection.

3. Navigating EU Cybersecurity Regulations

Radio Equipment Directive (RED) and EN 18031-1:2024 & :2025 standards are crucial for designing secure IoT devices.
Compliance with these regulations ensures market access and builds consumer trust.

4. Ensuring Secure Cloud Connectivity

Methods for secure cloud connectivity, including device provisioning and data encryption, were covered.
Tools like QuarkLink help with secure remote provisioning.

5. EMC Shielding & EMR Protection

EMC Shielding: Prevents electromagnetic interference (EMI) from affecting device performance.
Würth Elektronik’s EMC Components: Products like the WE-SHC Shielding Cabinet help protect sensitive components from electromagnetic radiation (EMR), ensuring compliance with EMC standards and improving Electromagnetic Susceptibility (EMS).

6. Key Takeaways

Conduct early cybersecurity risk assessments.
Compliance with EN 18031-1 and other standards is critical.
Security by Design is essential for creating resilient IoT devices.
Effective EMC shielding is necessary to protect devices from interference.

This workshop reinforced the significance of proactive cybersecurity and the role of EMC shielding in IoT development. Let’s continue to innovate, design secure solutions, and work towards a safer, connected future!
