Abstract
Provided is an infection-spreading attack detection system and method, as well as a program enabling an occurrence of an infection-spreading attack to be detected with high accuracy. A first feature amount is calculated based on traffic information on a packet transferred by a transfer device, and M partial address space(s) are identified to be a monitoring target based on the first feature amount. A second feature amount is calculated for each of the M partial address space(s) based on the traffic information related to the M partial address space(s). Abnormality detection determination is performed on each of the M partial address space(s) based on the second feature amount. Whether the infection-spreading attack has occurred is determined by evaluating M determination results.
