PROBLEM TO BE SOLVED: To provide a security device whereby, when receiving a frame suspected of being an attack frame, it is possible to reduce adverse influence caused by the frame or the like .SOLUTION: A security device 2110 connected to a bus in a vehicle 2100 includes a determination unit 2113 for determining whether a predetermined condition for determining the presence or absence of the probability that a frame received by a receiver 2111 for receiving frames from the bus is an attack frame is satisfied or not, an achieving unit 2114 for controlling so that a determination request is transmitted to an external device 2200 when the determination unit 2113 determines that the predetermined condition is satisfied, and achieving a determination result to be transmitted from the external device 2200 according to the determination request, and an output unit 2115 for outputting first presentation information when the determination unit 2113 determines that the predetermined condition is satisfied, and outputting second presentation information when the achieving unit 2114 achieves the determination result from the external device 2200.SELECTED DRAWING: Figure 33

    【課題】攻撃フレームであることが疑わしいフレームを受信した場合に、そのフレーム等による悪影響を低減化し得るセキュリティ装置を提供する。【解決手段】車両2100内のバスに接続されたセキュリティ装置2110であって、バスからフレームを受信する受信部2111により受信されたフレームについて、攻撃フレームである可能性の有無を区別するための所定条件が満たされるか否かを判定する判定部2113と、所定条件が満たされると判定部2113が判定した場合に車両外の外部装置2200に判定要求が伝達されるように制御して、判定要求に応じて外部装置2200から伝達される判定結果を取得する取得部2114と、所定条件が満たされると判定部2113が判定した場合に第1提示用情報を出力し、外部装置2200からの判定結果を取得部2114が取得した場合に第2提示用情報を出力する出力部2115とを備える。【選択図】図33
