This question explores Internet of Things and addresses practical considerations related to: What's the best approach for secure device onboarding in large IoT networks?

Secure device onboarding in large IoT networks involves establishing a reliable and secure method for provisioning devices while ensuring their authenticity and integrity. This process typically employs protocols like MQTT with TLS, secure boot, and device identity management to prevent unauthorized access and tampering. Utilize a secure boot mechanism to ensure the device firmware is authentic and has not been tampered with. Implement device identity management using unique identifiers and cryptographic keys for each device. Use secure communication protocols like MQTT with TLS to encrypt data during onboarding and operation. Leverage cloud IoT platforms to manage device credentials and access policies centrally. Regularly update device firmware and security policies to address vulnerabilities and enhance security. ADDITIONAL COMMENT: Consider using a Public Key Infrastructure (PKI) to manage device certificates and keys. Ensure that all devices support over-the-air (OTA) updates for security patches. Conduct regular security audits and penetration testing to identify potential weaknesses. Implement network segmentation to isolate devices and limit the impact of potential breaches. ✅
