Little Snitch deserves a post on it’s own.

Little Snitch, together with Glowworm FW got a mention on my “Secure OS X” article. When I started doing more work on a PowerMac G4 of a company, which had Little Snitch installed, I wanted to inject an F-Script workspace into Praetorian for some clean testing. Little Snitch amazed me.

I don’t know how it achieves this (trapping system calls, most likely) but it’s quite a feat to be able to stop an arbitrary code injection like that. Firewall? No, this has gone beyond and above firewall. This is a program for security-oriented users. How’s that for being in control?

If these people start adding even more features (and I have no doubt that they will) I will become a great, great fan of Little Snitch. Now, if only the icon were better. But there are designers like me and other far greater people (Adam Betts, I’m talking to you!) who love to design replacement icons. I think both firewall programs, in general, could use more interface and icon design love. But they already provide excellent, stable functionality. Go check them out.
