INTEROP: NAC Frustration is Mounting
“‘NAC is still a part of enterprises’ strategies, it’s still important,’ says Josh Corman, host protection architect for IBM’s Internet Security Systems unit. ‘But there are some issues with it that are hard to get around.’
“Those issues, in a nutshell, are cost, complexity, and vulnerabilities, experts say. While enterprises are intrigued by the notion of vetting users and devices before allowing them onto the network, they are still struggling with a wide array of products and functionality, time-consuming implementations — and researchers who keep finding ways to beat NAC defenses.
“TheInfoPro (TIP), an independent research organization based here, tomorrow will release a new study, which reports that the number of enterprises using NAC has actually declined over the past 18 months, from 35 percent in early 2006 to 26 percent today. During this same period, the number of organizations that do not plan to implement NAC has risen from 21 percent to 24 percent, the research organization says.
