  OpenSnitch is a GNU/Linux interactive application firewall inspired by Little Snitch.

As for "come to linux", that's also not really the right way to think about things. Linux isn't one platform; it's a spectrum of interrelated and associated applications that are all individually created by a massive network of loosely coordinated volunteers. There is no sense in waiting for something to "come to linux". The feature you're asking for is already here, via OpenSnitch, as mentioned elsewhere in the comments. Someone made it. Install the program that does the thing you want. That's how linux works. Every individual part of Linux, from the shell itself, to the ls command that shows directory contents, to the kernel, to the desktop environment, to the file manager are all individual programs that exist separately from one another. Linux distributions just say "yeah these all go together kinda well" and then wrap them up as a unit and ship them off. The point of linux is being able to say "but I like this better" and adding it. You don't have to wait for Microsoft to "add" a feature you want.
