What is Network Access Control?

Network access control, or NAC, is the set of tools, processes, and protocols that govern access to network-connected resources. It is a multifaceted discipline that involves access control solutions for different types of resources, including conventional PCs and servers, and also network routers, IoT devices, and more.

NAC also applies to data that travels over the network, and the resources it helps to secure may be physical (as in the case of hardware routers or servers) or software-defined, virtual resources (such as a software firewall or a virtual machine).In a bit more detail, network access control is a solution that integrates with your company’s network infrastructure to identify, assign, and enforce pre-determined rules or policies to manage the access to your network.
