| Linda Tucci, Senior News Writer
CIOs and chief information security officers whose network managers are evaluating network access control (NAC) products are advised to lay down some guidelines for finding the right solution. NAC now has several uses and as many potential pitfalls. An organization should define its primary usage case for NAC, map out a plan for taking advantage of NAC's other uses and decide on an enforcement protocol. Otherwise, it risks choosing the wrong vendor or product. Some CIOs and their staffs may have soured on NAC after it was overhyped in 2005. Many IT departments learned the hard way that NAC was difficult to deploy, a drag on the network and users, and of limited benefit for managed devices. Useful no doubt on a college campus, with its annual onslaught of users bearing personal laptops, NAC was less compelling for your average, buttoned-down big company. Vendors delayed NAC plans, shifted gears, closed up shop or got gobbled up. But network access control technology has undergone a personality change since its splashy debut some six years ago. Then, worms were the latest plague and NAC products part of the solution. Today's NAC is all about the user, according to Gartner Inc. analyst Lawrence Orans -- in particular, corralling the ever-increasing population of outsiders who need access to corporate networks. In addition, companies must contend with employees using personal devices. Bring Your Own Computer has spread from the academy to the corporate world. "Network managers are very interested in establishing policies that control access to the network," Orans said. "I speak to hundreds of network managers a year, and there is not one that says I don't want more control over which devices or endpoints access the network. NAC is still very much alive."
