Out-of-band NAC uses existing network architecture

摘要

There are three important functions of network access control (NAC) systems. They are endpoint management and compliance, identity management and usage policy enforcement. Bradford Networks' NAC Director does all three -for wired, wireless and VPN systems - and it does it 100 percent out of band. There is no need to rewire your existing enterprise to implement NAC Director. NAC Director is an appliance that sits on the perimeter of the network and notes all users attempting to enter the network. Each user has an agent on their computer that can be either persistent or dissolvable. Persistent agents are deployed to regular employees and contractors who enter the network routinely, while dissolvable agents are appropriate for ad hoc visitors to the network. Agents are tied to MAC addresses.
