PROBLEM TO BE SOLVED: To effectively detect an attack of unauthorized communication, while reducing processing load.SOLUTION: A detection system 100 includes: a repeater 120 which repeats communication with a server to be monitored; a detection apparatus 130; and a control apparatus 110. The control apparatus 110 transmits an instruction to the detection apparatus 130 to mirror the communication repeated by the repeater 120 when a fault is detected in information on a communication resource of the server. The detection apparatus 130 detects unauthorized communication from communication mirrored in response to the instruction transmitted by the control apparatus 110. The control apparatus 110 transmits an instruction to shut off the specified unauthorized communication, to the repeater 120, on the basis of a result detected by the detection apparatus 130.SELECTED DRAWING: Figure 1
