The present disclosure relates to a security device, a network system, and an attack detection method, the security device (2110) connected to a bus in a vehicle being provided with: a determination unit (2113) that determines whether or not a predetermined condition for distinguishing whether or not there is a possibility of being an attack frame is satisfied with respect to a frame received by areception unit (2111) that receives a frame from the bus; an acquisition unit (2114) that performs control so as to transmit a determination request to an external device (2200) outside the vehicle when the determination unit determines that the predetermined condition is satisfied, and acquires a determination result transmitted from the external device in accordance with the determination request; and an output unit (2115) that outputs the first presentation information when the determination unit determines that the predetermined condition is satisfied, and outputs the second presentationinformation when the acquisition unit acquires the determination result from the external device.

    本公开涉及安全装置、网络系统以及攻击检测方法,与车辆内的总线连接的安全装置(2110)具备:判定部(2113),其针对由从总线接收帧的接收部(2111)接收到的帧,判定是否满足预定条件,所述预定条件用于区分有无可能是攻击帧;取得部(2114),其在判定部判定为满足预定条件的情况下,进行控制以向车辆外的外部装置(2200)传达判定请求,取得根据判定请求而从外部装置传达的判定结果;以及输出部(2115),其在判定部判定为满足预定条件的情况下输出第1提示用信息,在取得部取得了来自外部装置的判定结果的情况下输出第2提示用信息。
