ISO 15031-7:2013给出了通过车辆诊断数据链路保护道路车辆模块免受未经授权入侵的指南。这些安全措施为车辆制造商提供了灵活性，使其能够根据自己的具体需求定制安全措施，并且不排除其他附加措施。 ISO 15031-7:2013适用于固态存储器内容可通过诊断数据通信链路从电子模块外部更改的车辆模块。此类改动可能会损坏车辆的电子设备或其他部件，使其在遵守政府法规或车辆制造商的安全利益方面面临风险。

ISO 15031-7:2013 gives guidelines for the protection of road vehicle modules from unauthorized intrusion through a vehicle diagnostic data link. These security measures offer vehicle manufacturers the flexibility to tailor their security to their own specific needs and do not exclude other, additional measures. ISO 15031-7:2013 applies to vehicle modules whose solid-state memory contents are able to be altered from outside the electronic module through a diagnostic data communication link. Such alteration could potentially damage a vehicle's electronics or other components, placing at risk its compliance with government legislation or the vehicle manufacturer's interests in respect of security.
