To provide a data analysis device capable of detecting even an advanced cyberattack with higher accuracy.SOLUTION: A data analysis server 200 to provide a function of a data analysis device comprises: data acquisition units 210 that acquire vehicle data indicating a traveling state of a first vehicle, and acquire vehicle-outside data indicating a condition outside the first vehicle from at least one of a traffic base system and a second vehicle other than the first vehicle in an area where the first vehicle is traveling; and a determination unit 230 that executes a first determination to determine whether or not there is any inconsistency between the traveling state of the first vehicle indicated by the vehicle data and the outside condition indicated by the vehicle-outside data, and outputs the result of the first determination for the first vehicle.SELECTED DRAWING: Figure 4

    【課題】高度化したサイバー攻撃であってもより高い精度で検知することができるデータ解析装置を提供する。【解決手段】データ解析装置の機能を提供するデータ解析サーバ200は、第一車両の走行状態を示す車両データを取得し、第一車両が走行しているエリアにおける第一車両以外の第二車両又は交通基盤システムの少なくとも一方から第一車両の車外状況を示す車外データを取得するデータ取得部210と、車両データが示す第一車両の走行状態と、車外データが示す車外状況とに不整合があるかを判定する第一判定を実行して、第一車両についての第一判定の結果を出力する判定部230とを備える。【選択図】図4
