Patent number: 11805142Abstract: A communication system including an operational network including a host and a learning and detection server, and a staging network including a host of the same type as the host, a test execution server, and a learning and detection server. The test execution server performs a communication test by transmitting test communication in a normal state to the host and receiving communication performed by the host. The learning and detection server learns the communication of the host, generates an initial model for detecting an anomalous communication of the host, and transmits the initial model to the learning and detection server. The learning and detection server learns the communication of the host and generates a model for detecting an anomalous communication of the host, while monitoring the communication of the host using the initial model received from the learning and detection server.Type: GrantFiled: June 26, 2019Date of Patent: October 31, 2023Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Takuya Minami, Tomoyasu Sato, Naoto Fujiki, Takeshi Nakatsuru, Masami Izumi
