IoT Privacy and Security by Design

IoT Privacy and Security by Design IoT devices connect homes, offices, and cities, but security and privacy can be weak. Designing devices with privacy and security built in from day one helps protect users and reduces bugs and recalls later. A by-design approach means thinking about threats, data flows, and user control at every stage, from hardware to software to cloud services. Principles to follow in design: Data minimization: collect only what you need and keep it local when possible. Unique credentials: avoid default passwords and assign per-device keys. Strong authentication: use mutual TLS and strict access control. Secure updates: sign firmware and provide verifiable over‑the‑air updates. Secure boot and hardware root of trust: verify firmware before it runs. Encryption: protect data at rest and in transit. Defense in depth: layer security controls across hardware, software, and network. In practice, teams should perform threat modeling early, design a secure development lifecycle, and check the supply chain. ...
