Title: Authentication device and recording medium for storing program for operating the device
Inventor: NAKABAYASHI KIYOHIRO
IPC: G06F21/44
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To provide an authentication device which makes it impossible to infiltrate into the network in an organization until it is successfully authenticated and can be authenticated for each server of the intra-organization network. SOLUTION: In an authentication device 4 arranged at an entrance of an intra-organization network 2, a command monitoring part 42 monitors data which an external terminal 5 transmits and detects a log-in command to each server 21. Every time the log-in command is detected, an authentication part 43 authenticates the external terminal 5 and authenticates by the server. A communication control part 41 transfers only a communication between the external terminal 5 successful in the authentication and the server 21. As long as authentication of other servers 21 is not successful even if the authentication of a server 21 is successful, the authentication device 4 does not allow the connection between the external terminal 5 and the server 21.  Thus, it is possible to perform authentication for each server without increasing the number of authentications and increasing the traffic of the intra-organization network 2.
