Snitching on Apps That Snitch On You
Apps have a bad habit of snitching on their owners. While this is a much bigger problem on Android and iOS, it's still valuable to detect when apps phone home on Linux. Unfortunately most Linux firewall software is designed for servers and focused on inbound connections.
This talk will cover using and tuning OpenSnitch, Linux software that prompts you whenever an app makes outbound connections and allows you to make sophisticated per-app rules to have tight control over your apps' network connections. This adaptive software works both in desktop and mobile Linux and this talk will explore how I personally use OpenSnitch on my mobile Linux device.
