Asset detection method, system and device based on configuration management database and storage medium

The invention provides an asset detection method, system and device based on a configuration management database and a storage medium. The method comprises the following steps that a calculation instance sends a command to an MID server; the MID server receives the instruction and sends CI detection to various devices, applications and services in the managed network, or feeds back a CI file to a calculation instance; and after receiving the feedback of the MID server, the calculation instance performs comparison and new mapping with the CI item in the configuration management database, and updates the CI to obtain the asset information. According to the method, an MID server is deployed to scan, classify, identify and detect assets, a sensitive hash algorithm for optimizing mass webpage deduplication by constructing a CI feature vector is used for judging the asset change condition, dynamic CI is established, information sharing with an enterprise configuration management database is achieved, service mappin
