As a security countermeasure method for software executed by a vehicle, the software is configured from a plurality of first modules, the vehicle is provided with a ROM for holding a plurality of second modules respectively corresponding to the plurality of first modules, the vehicle confirms whether or not there is an abnormality for each first module among the plurality of first modules, and when an abnormal first module is detected, the vehicle executes a security countermeasure method for the software. An abnormal first module is extracted from the software, a second module corresponding to the abnormal first module is read from the ROM, and the abnormal first module in the software is rewritten into the second module read from the ROM.
作为车辆所执行的软件的安全对策方法,软件由多个第一模块构成,车辆具备用于保持与多个第一模块分别对应的多个第二模块的ROM,车辆针对多个第一模块中的各个第一模块确认是否存在异常,在检测出异常的第一模块的情况下,从软件中提取异常的第一模块,从ROM读出与异常的第一模块对应的第二模块,将软件内的异常的第一模块改写为从ROM读出的第二模块。
