A web app that only has to read its own files and listen on a port often runs able to write anywhere on the filesystem, see every other process's temp files, and acquire new privileges at will. If that service is ever compromised, all of that latent power becomes the attacker's. Systemd has a deep sandboxing toolkit built directly into the service manager — no extra software, just directives in the unit file — that strips a service down to only what it actually requires. This guide hardens a unit step by step and scores the result.</p>
