Among the most disruptive change in Linux over the last decade has been in the introduction and broad integration of the systemd init system into Linux. In a keynote session at the CoreOS Fest in Berlin this week, Lennart Poettering, one of the lead developers of systemd delivered a detailed technical keynote on some of the key parameters in systemd and how they can be used to secure Linux servers. Poettering also provided some very controversial comments on how systemd stacks up against SELinux for helping to secure Linux servers.
