How to Isolate X11 Applications with LXC for Enhanced Security
This article provides a technical guide on using LXC (Linux Containers) to isolate X11 applications — such as web browsers and Electron-based apps — from the host system for enhanced security. The author explains how to install and configure LXC on Arch Linux, set up networking capabilities for containers, and run GUI applications inside containers to mitigate the risk of a compromised browser exposing the user's entire home directory. The procedure is detailed with command-line instructions and is adaptable to other Linux distributions.
Key quotes
Wouldn't it be nice to add an extra layer of security to a web browser or an Electron-based IM application?
After all, if a browser is compromised, the user's entire home directory may be at risk.
Let's mitigate this by using LXC to isolate the application from the host system.
The system used in this example is Arch Linux, but the procedure should be easily adaptable to other distributions.
