This page contains a detailed overview and comparison of Kicksecure and Debian regarding security hardening, privacy defaults and usability.

Introduction

This wiki page compares the security‑focused, hardened defaults of Kicksecure against upstream Debian. The differences are comprehensively detailed in several tables and visual highlighted below. The considered aspects are security hardening, a couple of privacy aspects and usability aspects.

Functional APT sources list	Pre-configured and working APT sources to ensure package updates and installations function out of the box.	Yes	No
sudo pre‑configured	sudo is ready to use without additional setup, allowing safe privilege escalation by default.	Yes	Depends.
bash‑completion, zsh shell	Command-line enhancements like tab completion and Zsh shell for improved terminal usability.	Yes	No
vm-config-dist		Yes	No
usability‑misc		Yes	No
Popular apps pre‑installed	Frequently used applications are pre-installed with secure defaults for convenience and security.	Yes with secure defaults	No
chmod-calc pre-installed	Comprehensive File and Directory Inspection Tool	Yes	No

Opt-in and Testers

Upcoming

• upcoming in Kicksecure 18:

## Emergency shutdown

- Forcibly powers off the system if the drive the system booted from is
  removed from the system.
- Forcibly powers off the system if a user-configurable "panic key sequence"
  is pressed (Ctrl+Alt+Delete by default).
- Forcibly powers off the system if
  `sudo /run/emerg-shutdown --instant-shutdown` is called.
- Optional - Forcibly powers off the system if shutdown gets stuck for longer
  than a user-configurable number of seconds (30 by default). Requires tuning
  by the user to function properly, see notes in
  `/etc/security-misc/emerg-shutdown/30_security_misc.conf`.

Attribution

• Not anti-Debian: This article should not be misunderstood as "Debian hate."
• Lineage: Kicksecure is based on Debian.
• Fork friendly: Debian welcomes software forks, meaning anyone can create a new project by copying Debian under the respective licenses and developing it in their own way. See also Debian is Fork Friendly.
• Gratitude: Without Debian, Kicksecure would not exist. Gratitude is expressed to the Debian project and its contributors.

We stand on the shoulders of giants - Kicksecure and many other Libre software projects are only made possible because people invested in writing code that is kept accessible for the public benefit.Reasons for Freedom Software / Open Source
