Dive into the core of modern Linux boot and service management. The Systemd & Service Management module breaks down the architecture of unit files, targets, and timers.

You will learn to master systemctl for starting, stopping, and masking services, and understand the critical security implications of writable service files. By the end of this module, you will know how to build custom services, detect malicious persistence mechanisms, and secure the systemd environment against privilege escalation.
