Madaidan recommends that you disable [unprivileged user namespaces](https://www.containerlabs.kubedaily.com/LXC/Linux%20Containers/User_namespaces.html) due to the [significant attack surface for privilege escalation](https://madaidans-insecurities.github.io/linux.html#kernel).

If you are using Kicksecure or Whonix, most of this hardening is included by default. If you are using Debian, you should consider [morphing it into Kicksecure](https://www.kicksecure.com/wiki/Debian). On other distributions, you can copy the [configuration files from Kicksecure](https://github.com/Kicksecure/security-misc/tree/master/usr/lib/sysctl.d) into `/etc/sysctl.d/` (but note that these configurations do not disable unprivileged user namespaces).
