Abstract: In order to avoid multiple crossings and repeated network security testing and evaluation to railway tested and evaluated objects, and meet the practical needs of one-time entry and multiple report outputs, this paper analyzed the purpose, content, methods, and conclusions of different types of testing and evaluation, such as network security level protection testing and evaluation, risk assessment, commercial password application security assessment, data security risk assessment, network security technology inspection, etc. It proposed a railway multi integrated network security testing and evaluation system and designed a multi integrated testing and evaluation process, which was of great significance for reducing personnel consumption of the tested and evaluated objects and improving the efficiency of testing and evaluation work.
