Linux generally comes with iptables which can be used for it, but more efficiently most distributions have some system for access control like SELinux or apparmor which can also do it. Sorry not familiar if this is a thing on Windows/Mac/BSD's. In fact I think Android has SELinux built in, but not user accessible without root.
