Patent number: 7516242Abstract: An integrated information communication system capable of improving information security is provided, in which an IP packet is detected which is sent from an external area toward either an operation management server or a relay apparatus, the detected IP packet is not entered inside the integrated information communication system in order to reduce such a chance that the operation management server and the relay apparatus are unfairly attacked. Also, such an IP packet is detected and discarded, which violates an address application rule established so as to keep secret of a communication company network. An address which is applied to either an operation management server or a relay apparatus employed in the integrated information communication system is sectioned, or classified as an “address which is not opened outside network” with respect to an external area of the communication system. A packet filter is installed in an address control apparatus.Type: GrantFiled: October 19, 2005Date of Patent: April 7, 2009Assignees: The Distribution Systems Research Institute, Miyaguchi Research Co., Ltd.Inventors: Hisao Furukawa, Shoji Miyaguchi
