Because of the complexity of each system of big data platform, it is very important for the evaluation company to check the security configuration of each system. Big data needs high computing power and large storage capacity. Each component system generally uses distributed system, the appraiser needs to log on to the many configuration files of each system to check the security configuration that needs to be strengthened, which is not only inefficient but also easy to miss important configuration items. Aiming at these problems, this paper designs a security configuration detection system suitable for Hadoop big data platform. According to the knowledge base, the system can directly issue the results of security configuration inspection, which greatly improves the efficiency of the appraiser.
