A. What Is Network Access Control?
Protecting the average corporate network from attacks is incredibly complicated (and expensive). By the mid 1990s, complex toolkits had been supplanted by pre-built firewall software packages and pre-built intrusion detection systems. As performance and usability requirements increased, software moved to hardware, and by 2000, the number of companies buying and deploying perimeter security skyrocketed. Features were integrated, costs came down, technologies improved, and today you can buy a top-of-the-line, stateful-inspection firewall at the local home electronics store. So has security technology innovation stopped? Are there no longer threats?
Year after year the CSI/FBI Computer Crime Survey shows that organizations experience about the same number of external attacks and internal attacks. Yet the makers of early network security products largely ignored threats from the inside, because there were no easy, product-based solutions. Instead, they targeted the boundary between the corporate LAN and the Internet, because they could build products to do that, and because this was the most obvious point at which to defend against attacks from the outside. Now, thanks to distributed Internet connectivity, VPNs, wireless technology, network-connected PDAs, and extranets, most large enterprise networks no longer have borders. While this increase in connectivity is great for employee productivity, it is a security nightmare.
There is a lot of talk in the security market about network access control (NAC), an attempt to build an intelligent... [download for more]
