AFWall+: Digital Door Controller - Take back control! (Part 4)

1. firewall

In the last part of the article series "Take back control! we got root rights on our Android system with the help of Magisk. This step was necessary because apps like AFWall+ and AdAway require root rights. https://www.kuketz-blog.de/magisk-bei-der-macht-von-root-take-back-control-teil3/

At this point, we should remember that switching to an alternative operating system like LineageOS does not necessarily protect us from the unwanted outflow of sensitive data. Rather, further adjustments are needed so that we can use the Android smartphone "self-determined". An important component of our defense strategy is the use of a firewall to control the Android's data traffic. Originally, firewalls were primarily intended to protect us from "dangers" from outside. However, this primary purpose of firewalls has changed more and more. Firewalls on client systems now increasingly serve to monitor and control outgoing data connections.

Various firewall solutions exist for Android - but only two are worth mentioning: NetGuard and AFWall+. In this article I present the installation and configuration of AFWall+.

2nd AFWall+

AFWall+ is a front-end for the firewall iptables known from the GNU/Linux world. It enables control over which app or system service should have access to the data network via 2G/3G/LTE/5G, roaming, WiFi or VPN. In my opinion it is an essential part of any rooted Android device to control the unwanted outflow of information.

AFWall+ is relatively easy to use in its basic functionality, as long as you have understood the concept of a firewall. It becomes complicated only with special use cases, which are represented by CustomScripts. If you are looking for a user-friendly alternative to AFWall+ or if you cannot / do not want to root your device, you should take a look at NetGuard.
