Open Source Summit North America 2025

The ability to quickly observe and respond to security threats on remote machines is critically important for business and infrastructure, yet gaps still exist when applying cryptographic attestation solutions in real-world scenarios. Accessible policy generation, clear ways to understand attestation results, and methods for handling system updates need to be available to make remote attestation feasible. Adapting attestation best practices and tools to environments like edge and IoT, with vast scale requirements and limited network connectivity, can pose challenges as well.

Using the speakers’ experience working on open source projects Keylime (remote attestation) and flightctl (edge management), the session will walk through design considerations and challenges in bringing these tools together to monitor remote fleets of edge, IoT, and cloud-based systems at key points in the devices’ lifecycles. Further, the session will discuss remaining open problems as well as some potential solutions working toward the goal of usable, clear, and accurate attestation of remote systems.
