PROBLEM TO BE SOLVED: To easily construct a high-performance system protecting a network system from a computer virus. SOLUTION: In this network security system, an information management device 301 is connected to a network communication network 101 connected with an information management server 201 performing management by installing prescribed antivirus software and completing disk inspection by the software as connection conditions of a user computer 401 to the network communication network 101, and the user computer 401 storing individual connection condition information about the connection conditions is connected through the information management device 301. The information management device 301 accesses the information management server 201 via the network communication network 101 to acquire the connection conditions, accesses the user computer 401 to acquire the individual connection condition information, and allows the connection of the user computer 401 to the network communication network 101 only when the individual connection condition information satisfies the connection conditions.
