Is Endpoint Security Replacing Network Security?

There have been rumors for some time that the network perimeter is dead. More users are relying on laptop computers connected over wireless networks, or via VPN from a hotel or coffee shop. Users have mobile phones that connect to network resources, and various methods of portable data storage- USB flash drives, mobile phones, digital cameras, MP3 players. If anyone can connect from anywhere and data is coming and going, it becomes virtually impossible to say what is ‘inside’ the network perimeter, and what is ‘outside’ the network perimeter. If all of that is true, should network security even be an issue? Why not declare a time of death, focus on endpoint security solutions and forget about the network? Read The Future of Network Security at Computerworld for a deeper look at this issue, as well as why the rumors of the death of network security might be exaggerated.

Cisco Merges Technologies to Create ‘oneNAC’

Recently, I wrote about the struggles NAC (Network Admission Control) solutions have been going through to gain acceptance. According to a Computerworld.com article, Cisco is working to deal with the issues that have faced NAC solutions by merging both of their NAC approaches together. The resulting NAC solution will reportedly be faster, less complex to implement, and easier to maintain than either of the existing solutions. Cisco believes that the unified approach, dubbed oneNAC, will solve the primary issues and provide the flexibility enterprises are looking for to begin adopting NAC as a security solution.

NAC Continues To Struggle

A couple of years ago the concept of network access control (NAC) was introduced and many touted it as the next shift in network security technology. A product that sits between the client and the network and ensures that devices are clean and safe and meet with the prescribed network security policy before allowing them to connect with network resources seems like a no-lose situation. As it turns out, the various implementations of NAC have had their share of issues and NAC adoption hasn’t been quite the tidal wave of acceptance that some had predicted. Check out this Computerworld.com article for more about the issues with NAC and the current state of NAC implementation.
