Network Access Control is all the rage these days when it comes to network security technologies. “All of the vendors have something they call NAC,” says Gartner Inc. vice president and distinguished analyst John Pescatore in a SearchNetworking.com article. Indeed, you and your customers have myriad offerings to choose from — if you decide NAC is the way to go. But making that decision isn’t an easy one. The same article offers strategies that can help you and your customer determine if NAC is in order and to what degree. Certain vendors may have you believe that NAC should be present throughout the network, but that’s not necessarily the case. After you read SearchNetworking’s article, cruise on over to SearchSecurityChannel.com and take a look at our Network Access Control Crash Course, which provides an overview of network access control technologies, their role in network security and where the market stands, with a focus on the three big players — Cisco, Microsoft and Trusted Computing Group.
