Situation
Flood prone areas require a network of government–managed flood sensors and actuators that warn emergency agencies of flooding in advance, so that people and traffic can be directed to safety.
Most of these OT devices have been in service for up to 20 years, and now are being connected to the Internet via secure gateways to gain real-time access to flood data. Modern, PKI-based security is required to mitigate the previously weak credentials on these devices not designed to be online as part of the IoT.
Solution
Device Authority KeyScaler was used to provide:
- Generation of device root of trust using DDKG for Automated Device Provisioning of secure gateways
- PKI Services for IoT utilizing x.509 Certificates issues by the enterprise CA
- Identity Lifecycle Management including automatic provisioning to the cloud
- External Threat Intelligence Data from Defender for IoT to inform device authorization safety
