Title

NixOS system configuration files and directories must be group-owned by root. (Cat II impact)

Discussion

Without the capability to restrict the roles and individuals that can select which events are audited, unauthorized personnel may be able to prevent the auditing of critical events. Misconfigured audits may degrade the system's performance by overwhelming the audit log. Misconfigured audits may also make it more difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

Check Content

Verify that the NixOS system configuration files and directories are group-owned by root with the following command: $ sudo find /etc/nixos -exec stat -c "%G %n" {} \; root /etc/nixos root /etc/nixos/configuration.nix root /etc/nixos/hardware-configuration.nix If the system configuration files and directories are not group-owned by root, this is a finding.

Fix Text

Configure the NixOS system configuration files and directories to be group-owned by root by using the following command: $ sudo find /etc/nixos -exec chown -R :root {} \; Rebuild the NixOS configuration with the following command: $ sudo nixos-rebuild switch
