The process of assigning, verifying, and managing unique cryptographic identities for IoT and connected devices throughout their lifecycle. Device identity management uses certificates, hardware security modules, or manufacturer-provisioned keys to authenticate each device before granting network access and to encrypt communications between devices and backend systems.

Why Device Identity Management Matters for Your Cybersecurity Career

Without strong device identity, attackers can impersonate IoT devices to access networks or inject false data. Security engineers building IoT platforms must implement certificate lifecycle management at scale. Security architects evaluating IoT vendors should assess how devices are authenticated. This is a growing specialization within identity and access management.
