Editing Application firewall (section)

== Implementations ==
There are various application firewalls available, including both free and open source software and commercial products.

=== Mac OS X ===
Starting with Mac OS X Leopard, an implementation of the TrustedBSD MAC framework (taken from FreeBSD), was included.<ref>{{cite web|url=http://www.trustedbsd.org/mac.html|title=Mandatory Access Control (MAC) Framework|publisher=TrustedBSD|access-date=2013-09-05}}</ref> The TrustedBSD MAC framework is used to sandbox services and provides a firewall layer, given the configuration of the sharing services in [[Mac operating systems|Mac OS]] X Leopard and Snow Leopard. Third-party applications can provide extended functionality, including filtering out outgoing connections by app.
