Summary
This post details Cloudflare's implementation of secure boot at the Linux kernel level, focusing on enforcing signed kernel modules. It demonstrates how this prevents unauthorized code injection by requiring modules to have valid signatures, thereby enhancing system integrity and security. The post contrasts this with less secure configurations found in standard distributions and highlights the importance of this measure for Cloudflare's production environments.
