right, I used to have a firewall that could whitelist apps in the 90s on Windows (can't remember the name)... iptables can't even do that as far as I know... but there is https://github.com/evilsocket/opensnitch that I still need to try (I no longer use Windows).
Nowadays I use TinyWall[1] on Windows. A simple firewall with a whitelist and some convenience functions.

ZoneAlarm? Was in my default set of programs to install in the XP era.
