PROBLEM TO BE SOLVED: To establish an analysis system having a high security characteristics which prevents confidential information stored in a server from leaking, even when an outsider uses an in-company network for the purpose of troubleshooting for an analysis apparatus or the like. SOLUTION: An analysis network 1 where the analysis apparatus 11a and a client 12a for controlling it are connected via a first communication line network 10, is brought not to directly connect with the in-company network 2, to which the server 21 or the like is connected via a second communication line network 20, and is interconnected with it via an intermediate connection device 3. When authentication is carried out, a procedure is completed such that the client 12a sends a connection request to the server 21 by using a specific port number. The intermediate connection device 3 is set so as to allow the connection request which is sent from the analysis network 1 side to the in-company network 2 side and has the specific port number corresponding to a specific terminal (server 21), to pass therethrough, whereby the request is received by the server 21, and the connection is established. In the procedures different from normal ones, the port number is set specially. Therefore, unauthorized accesses by others, who try accessing according to the port number, become very difficult.
