<p>A network security system performing an authentication process on users accessing a network and a network security process is provided. The network security system includes: a security server for storing and managing personal security policies applied to registered users and security information on the personal security policies; a terminal for transmitting basic authentication information input by a user to request authentication; and an authentication server for performing the authentication process on the user based on the basic authentication information received from the terminal and receiving the personal security policies applied to the user and the associated security information from the security server, wherein, when authentication is granted to the user, the authentication server determines whether or not to allow the terminal to access the network based on the personal security policies and the security information received from the security server. Accordingly, it is determined whether nor not to allow the user terminal to access the network based on an installation status of the specific software in the security information applied to the user at the same time of performing the authentication process on the user accessing the network, so that it is possible to implement optimal security.</p> |
