Patent attributes
An apparatus comprises a processing platform configured to communicate with a plurality of IoT devices over at least one network. The processing platform implements a security-as-a-service portal accessible to the IoT devices, the portal comprising an analytics engine configured to assign trust scores to respective ones of the IoT devices. The security-as-a-service portal provides authentication leveling functionality for the IoT devices based at least in part on the assigned trust scores. In accordance with the authentication leveling functionality, a first one of the IoT devices accesses the security-as-a-service portal to identify a level of authentication to be applied by the first IoT device in authenticating a second one of the IoT devices. The security-as-a-service portal may determine the authentication level to be applied by the first IoT device in authenticating the second IoT device based at least in part on the trust score assigned to the second IoT device.
