Feature: Operating system attacks from network resources

Network security firewalls provide a 'bottleneck' facility at strategic points on the network to prevent wholesale attacks of systems on a network. It's pretty common practice to put a firewall facility between known troublesome networks such as the Internet. Oddly enough, most companies do not implement firewall facilities between different company divisions, 'sister' company network connections, customer network connections and other third party or vendor supplied network connections. The funny part is that most of the documented network break-ins are from the non-Internet connections (although the Internet break-ins are accelerating).
