NAC, Radius Solutions
Network Access Control (NAC) is a solution designed to spread the security principles specified by the institutions to the entire network and to prevent/limit the end-users who do not comply with these principles. The purpose of using NAC is to ensure that only users who comply with security principles and have been granted access are included in the network.
Radius (Remote Authentication Dial-in User Service) is a service where the user name and password verification, reporting, setting access times, and authorization are performed for users who connect to servers remotely
Thanks to this service, new accounts can be opened for users, authorizations can be made, and thus a central control is achieved. This method is often preferred especially in wireless networks.
