After receiving an update to my security center (10.8.08) I noticed that my firewall settings had been changed. The options available in build 10.0.209 are less than what was offered before. Now you have only 3 available and one of them is Stealth. So you now have settings, monitor or stealth. To me that's a downgrade of features. Why change?
The update left my system in a monitor mode which is not what I wanted.
