[Problem] To provide a log analysis system which is capable of detecting unauthorized access, an analysis device, an analysis method and a storage medium on which an analysis program is stored. [Solution] A client terminal 200 communicates with an external communication device. A relay device 100 relays communications between the external communication device and the client terminal 200, in accordance with a request from the client terminal 200. An analysis device 300 analyzes the content of communications by the client terminal 200. Then, the client terminal 200 stores program information indicating a program that handled communications with the external communication device. The relay device 100 stores a relay log that indicates each request, made by the client terminal 200, to communicate with the external communication device. In addition, the analysis device 300 compares the program information and the relay log. |
