# Application-Based Firewall
Gain more control over the built-in firewall. Specify the behavior of specific applications to either allow or block incoming connections.
I'm not 100% sure how I'm supposed to interpret this, but assuming we're talking about established connections, as opposed to "fire and forget" dumping of data with outgoing UDP-packets; Won't this pretty much kill off Little Snitch as a product?
If they are also blocking _outgoing_ traffic (doesn't sound like it from the wording above, but who knows. Maybe Apple are just "simplifying" to make things understandable to non-technical users), it surely kills of LS..
Or does it? "Quis custodiet ipsos custodes?"
I'd feel a _lot_ better trustig this kind of functionality with a third party vendor, as opposed to the one supplying my OS.
This aside, does anyone know how LS interacts with said buildt-in fw?
