# Linux

**Linux** is the open-source operating system family targeted by the URZ's DNSSEC configuration guides. The documentation specifically addresses the nuances of different Linux distributions and their chosen DNS resolver implementations (such as `systemd-resolved` or `dnsmasq`).

The URZ provides specific guidance for Linux users to ensure that network security extensions like [[dnssec]] are correctly implemented across different versions of the OS, including legacy systems like Debian 9.
