Abstract: In recent years, in the continuous advancement of the construction of “digital government”, the “data gap” and “data island” between government departments have been gradually broken. As the core resource of digital government, data is an important driving force for national development，and also the most valuable core asset. With the largescale aggregation, integration and sharing of various data resources, a series of data securityrelated problems have emerged. For example, due to the high concentration of data, data is more likely to become the target of attacks, and a large number of illegal operations by internal personnel lead to data tampering and greatly increase. In order to solve the problem of data security in the field of transportation, this paper makes an indepth analysis of the main challenges of data security in the field of transportation technology and transportation, and proposes to create an “overall technical architecture of data security management and control”, and focuses on thinking and discussing the full life cycle security of data and data security operation    in the field of transportation. Data security management is not within the scope of this paper.
