What is secureblue?
secureblue is a security-focused, open-source operating system that ships as rpm-ostree container images derived from Fedora Atomic/CoreOS. It emphasizes proactive hardening—such as removing SUID binaries, enabling hardened_malloc, and disabling unprivileged user namespaces—while retaining Fedora’s default SELinux and user-friendly experience. With features like Network Time Security (NTS) via chrony, DNSSEC + DNS-over-TLS, robust firewall defaults, and optional LUKS TPM2/FIDO2 integration, secureblue aims to deliver a safer Linux environment without sacrificing everyday usability.
