The Cisco router NAC solves the problem. The so-called NAC is an architecture that allows multiple hardware and software components to work together to protect the user's network from adverse client attacks. 1. It is not easy to fully implement NAC, because the entire architecture contains too many different components from other vendors. For example, the architecture contains the NAC Policy Manager and multiple network systems, authentication servers
