Next-generation network access control (NG-NAC) systems enable organisations to not just know who and what is on their network, but also to put in place the role and device-based policy controls. The aim is to ensure devices are compliant before full or limited network access is granted by fixing configuration and security issues and then, once access is granted, maintain control and prevent on-going policy violation.
The influx of personal mobile devices in to the work place (or BYOD/bring your own device) needs policy on usage to be enforced. One of the enabling technologies is network access control (NAC). NAC serves to provide real-time visibility and control of all users and systems attempting to access network resources using managed, unmanaged, wired and wireless devices.
