Key quotes
· 3 pulledSystemd provides a very complete, robust method of controlling services, but it is optimized for success out of the box and not necessarily security.
This doc is meant to provide a snapshot of a number of hardening options that you can apply to systemd service units and podman quadlets to increase the overall security posture.
The options include everything from system permissions, time management, BPF, syscall & seccomp filters, all to make your system more secure.
Discover additional security options for systemd units, to include quadlets. These options are everything from system permissions, time manage, BPF, syscall & seccomp filters, etc., all to make your system more secure.
