[Abstract]:Aiming at the problem that the traditional log data analysis method can not effectively detect the massive attacks of distributed denial of service attacks, the detection accuracy of abnormal network packets is low, and the detection effect is not intuitive enough. The security visualization process of network data packets based on data block diagram is studied. The random data packets in the network are collected and analyzed by the data acquisition and statistics module. The node coordinate operation module is used to select the reasonable algorithm principle to calculate the attributes of the graph elements of the network data packet, and the graphic element of the network data packet is presented by the graphic display module. The effect of display model is regulated based on user's parameter control performance, and the detailed information in network data packet is obtained. The realization process of the data acquisition and statistics module and the graphic display module is given. The attacks and ports in the network data packets are detected by using the data block diagram, and the ports of different hosts in the network are displayed. The connection frequency, the number of packets transmitted and the attacks in them can realize the visual control of network data packet security. The experimental results show that the proposed method can accurately detect the attacks in the network and display the abnormal packets accurately.
