The abnormality detection device detects abnormalities in a network system including a first network and a second network having different communication protocols from each other. The abnormality detection device receives state information indicating the state of the moving body and acquired from the second network, transmits and receives an E frame by the communication protocol of the first network, stores an abnormality detection rule, and detects whether or not a control command contained in the received E frame is abnormal by referring to the state information and the abnormality detection rule. When detecting that the control command is abnormal, the abnormality detection device prohibits forwarding of the control command.
