This section will mainly summarizes the background and risks，objects and targets，modes and methods of emergency response in information system security of automobile enterprises，as well as the corresponding design ideas. In terms of emergency response risks，they are mainly divided into network security threats：APT attacks，virus flooding，security vulnerabilities，etc.，legal and regulatory requirements and regulatory penalties，and risks caused by inadequate data protection. In terms of the objects and targets of network security emergency response，automobile companies will set the corresponding objects and targets of emergency response according to the different business stages and types. In the formulation of emergency response mode，it can be roughly divided into three stages：grading，establishing the process，appointing the person in charge，doing the risk assessment and emergency drill stage，monitoring stage and post-processing and feedback stage. Five aspects should be considered in the design of specific emergency response scheme：security incident grading design，process design，tool design，training and drill of emergency response personnel，and response content design. Finally，this section summarizes and looks forward to the completion of emergency response construction of automobile enterprises，and proposes that automobile enterprises should build emergency response capacity according to their actual situation. And the risks in cars are everywhere. This section only outlines the main ones.
