Data acquisition method of network data security monitoring system

The invention discloses a data acquisition method of a network data security monitoring system, which belongs to the technical field of data acquisition and comprises the following steps: S1, setting an access IP trusted by an enterprise; s2, storing an enterprise trusted access IP; s3, generating an access IP white list; s4, storing the generated access IP white list; s5, collecting flow data of the enterprise in real time; s6, traffic data about the white list access IP in the enterprise traffic data are removed; s7, carrying out security monitoring on other traffic data; according to the invention, a trusted access IP of an enterprise can be set and stored before data acquisition, flow data related to the trusted access IP of the enterprise in data flow are eliminated during real-time data acquisition, and then other flow data are transmitted to the data security monitoring module for security monitoring. According to the data acquisition method, the safety monitoring function of the system is not influenc
