PKI Points the Way for Identity and Authentication in IoT

This sponsored article discusses the distinct security challenges of IoT devices and recommends foundational controls to secure them across their lifecycle, emphasizing cryptographically strong device identities ("birth certificates"), supply-chain visibility, revocation and quarantine approaches, secure update mechanisms, service-side authentication, and preplanned remediation. The author argues that Public Key Infrastructure (PKI) is a market-ready, interoperable solution to provide the authentication and encryption primitives needed for scalable IoT security.
