The modern, connected, embedded Linux IoT device is facing a fundamental problem: the more connected it gets, the more cybersecurity threats it faces. Data link reliability, especially in the marine case, also makes it hard to efficiently push sensor data to the cloud.

This talk shows how to implement a reliable sensor data path from a marine IoT device running the redpesk embedded distribution to the cloud. It starts with lessons learned from real-world use cases: sending data from thousands of sensors to a cloud backend served by a choppy connection. It then dives into the IoT.bzh microservice framework, its security model (based on SMACK and SELinux) and how we coupled it with RedisTimeSeries.

All this, in addition to an OpenID Connect service, allows one to securely and selectively funnel data from that target to the cloud. The talk concludes with a proposal on how this open infrastructure can be used by the community at large.
