Do you use Network Access Control ?

Almost half of organisations polled by ComputerWeekly/TechTarget said they do not use Network access control (NAC).

Of those who do, most use it for remote access (29%) and LAN access (27%) followed by 18% who use it only for guest access, 2% who use it for pre-connect assessment only and 2% who use it for both pre- and post-connect assessment.

The relatively low adoption of NAC despite the fact that the technology has been around for years, can be ascribed in part to the fact that IT departments still believe they live in the world where the majority of users have desktops, and the few laptops are brought into the office regularly, said Andrew Rose, principal analyst for security and risk at Forrester Research.

“They do not recognise that the landscape has shifted and that many users now bring their own device, or work away from the office for weeks at a time,” he said.

According to Rose, the fact that the basic network segmentation that some organisations have in place, perhaps where servers and desktops are segregated, or teams that work with sensitive data are screened from the network, may also serve to make the IT teams feel that NAC is non-essential.
