Chromium Hardening Guide

This guide helps users set up and utilize a Chromium-based browser with specific flags and policies. The guide covers three main sections: choosing a browser, applying policies, and persisting flags. The focus is on Linux and Windows, with additional notes for Android and MacOS.

It is essential to use a secure browser, and the guide suggests checking a browser selection page for assistance. The guide emphasizes using configuration files generated by an automated script, which is cross-platform and simple to use. Users can also manually edit the output files if needed.

Content blocking can be done through extensions, native/internal, and DNS/network methods. Extensions are generally discouraged due to potential security risks, while native/internal and DNS/network methods offer varying degrees of security and effectiveness. DNS filtering is recommended for its minimal performance impact and ability to resist censorship and tracking. However, HTTPS interception filtering should be avoided due to significant security risks.
