Not to mention that (unfortunately) we don't live in a completely free software world, so something like this is very useful if you're forced to run a proprietary program.

If an application is compromised or contains network functionality that doesn't do what you would like (and assuming you don't want to have to patch it and rebuild it) then something like this is incredibly useful.

> What is the purpose of an "application firewall" in an open source world?Īside from the problems with trying to read the source code for every application on your machine (which I guarantee you have not done), security is all about depth. Apparently few people can maintain a stable IP. What if an application hard codes an IP address? Answer: I see it in the source code. It is always possible that an application's "phoning home" behaviour could be documented by such users in public forums, etc. In an open source world, in the event a particular user does not "have the time" to read source code or even grep it for clues, chances are that some other user does have the time and compiles all his programs from source. IMHO that is misleading, but not surprising considering the source.

I think Microsoft puts some application they call a "firewall" on Windows. This is the way to stop the telemetry, IMHO. If a Windows user wants to run a "firewall" then IMO they need an additional computer, e.g., a gateway they control. IMHO a "firewall" operates on incoming packets from other computers, not packets originating from the computer running the firewall. In my opinion an "application firewall" is a misnomer. For instance if I want to reverse engineer the protocols used. I can also redirect traffic to localhost servers where I can log requests and analyze the captured packets.

I do make extensive use of the HOSTS file but not for blocking. I do not use a third party cache, I maintain a custom root and can use it to block wildcarded domains, something that cannot be done with /etc/hosts. Sometimes I run programs with ktrace (strace for Linux folks I guess) and look at the calls.īut truthfully in most cases controlling DNS catches most if not all of today's applications' attempts contact the mothership. I have yet to see any source code that attempted to obfuscate opening sockets. If I have the source code and I am curious I just read it. What is the purpose of an "application firewall" in an open source world? My plan is to make it far more modular than OpenSnitch with an client API so the GUI can be completely separate (and also perhaps allowing different clients to have different policies). Also Douane simply will not work properly with containers because of how it assumes that everything is in the host namespace.Īs an aside, I decided to write my own application-level firewall for GNU/Linux (mainly as an exercise to myself to learn Rust as well as learn more about low-level network programming in Linux). The only thing that you might argue is a benefit of using a kernel module is that figuring out the "path" for an application might be easier but I'm not sure I agree. My main complaint about implementing all of these things in kernel space is that it's simply not necessary - with netfilter_queue and connmark you can relay all decision making to userspace without losing any generality. It also has a bunch of questionable technical decisions in how policies are handled, especially when it comes to "edge cases" like processes with long paths or connections where the socket file descriptor is greater than 8 or something like that. Rather than implementing all of the rules and policy in userspace (as OpenSnitch does) it implements the rules in kernelspace.

I remember looking into Douane a while ago and was not impressed.
