Safe and Secure Field Updates of Embedded Linux Systems

Enrico Jörns | | RAUC, OTA, Talk

While updating is not a end in itself, a second part of my considerations goes even further and also works out the necessities and possible workflows for keeping the software stack of a project up to date and thus either preventing security issues or at least enabling a short reaction time in case of severe CVE'S discovered.

OTA field updates are a common requirement in modern embedded device deployments. The larger the amount of devices to control, the more important is having a good infrastructure that is reliable in updating and smart in rolling out the software.
