One would think that keeping the firewall updated with the latest, greatest version would result in better protection. Yet there are people who continue using older firewall software.
I realize that a firewall is a firewall and the whole point is to monitor and grant or deny permission to communicate. It seems like there would really be no way to improve on such a simple concept. Either a program communicates or it doesn't, or it communicates wherever you say it can.
So with respect to firewall-specific demands, is there anything that KPF4.x does that's better than 2.1.5? How important is the monitoring of applications and its attempts to launch other apps? I'm thinking about downgrading to 2.1.5 because while there were fewer features, the older version just seems much simpler to use.
