Protecting IT networks used to be a straightforward case of encircling computers and servers with a firewall and ensuring that all traffic passed through just one gateway. However, the increase in mobile workers, numbers and type of device and the amount of non-employees requiring network access, has led to a dissolving of that network perimeter. Access requests can come from anyone and anywhere, which is why organizations are turning to network access control (NAC) technologies.

This paper discusses why NAC is important and how it should be implemented on the endpoint for maximum protection.
