Document Type and Number:

Japanese Patent JP7501620

Kind Code:

B2

Abstract:

An attack detection apparatus that detects an attack on a network within equipment, improves detection accuracy of an attack on the network within the equipment by including a processor and a memory storing program instructions that cause the processor to extract a set of two messages that have the same payload from a plurality of messages transmitted in a certain period, and determine whether or not the attack is made on the basis of whether or not another message is transmitted between transmissions of the two messages of the set and an interval of transmission of the two messages.
