Little Snitch 2.0 now available
Objective Development relased Little Snitch 2.0 today.
Little Snitch is an outbound firewall, more or less. That is, it monitors all outbound connections and warns if an application makes any kind of connection for which there isn’t a rule permitting said connection.
The warning panel that comes up allows the user to allow or deny the conneciton and to do so one time only, until the app in question quits, or foreever. You can also specific that the app should only connect to a specific server and port, a specific server, a specific port (HTTP, for example), or any connection at all.
LS has an awesome rule editor built in and 2.0 adds a really neat traffic monitor.
All in all, it is a beautifully designed and highly functional piece of software.
I tend to run Little Snitch all the time. It can be a bit noisy when it is first set up, but that is quickly rectified as you refine your rule set.
Little Snitch has busted a handful of applications that “called home” or made connections to surprising places. (I busted an Apple application that was doing so — it was an accident and it was fixed before the software as ever released).
