FreeBSD is a Unix-like operating system mainly used in the server environment due to its extraordinary performance and stability in a networking environment.
It stands for Berkeley Software Distribution, and dates back to the early nineties, and with subsequent releases, it has focused on security, which is why there are three separate firewall solutions available: IPFW, IPFilter and PF.
Administrative access is provided via SSH, with the root username and the password chosen during setup.
There are no particular customization options on this template, as this is a minimal FreeBSD installation that leaves space for any type of use.
The unique feature is the choice of ZFS as a file system, which offers significant benefits and overcomes many limitations presented by traditional file systems.
