Abstract

The invention provides a network security situation awareness method based on a fusion decision. The method comprises the steps of collecting the sFlow data, NetFlow data, SNMP data and log data froma monitored network; preprocessing the collected sFlow data, NetFlow data, SNMP data and log data; and carrying out flow analysis and equipment performance analysis on the preprocessed data, and carrying out fusion through a fusion algorithm to obtain the security situation of the monitored network. According to the invention, the multi-source heterogeneous data information can be obtained for data fusion, and the safe operation condition of the whole network and whether the host in the network is attacked or not and even which attack category is attacked or not can be obtained, so that more accurate assessment is made for network security situation awareness.

Description

technical field [0001] This application relates to the technical field of network communication, and especially designs a method and system for network security situation awareness based on fusion decision-making. Background technique [0002] With the gradual popularization of the Internet and the rapid development of new technologies such as the Internet of Things, big data, and cloud computing, network security is always facing severe threats of intrusion. Most of the existing security devices are working independently, and can only detect and defend against one aspect of the network system, and their defects and limitations are gradually emerging. NSSA (Network Security Situation Awareness, Network Security Situation Awareness) came into being and gradually became one of the emerging research focuses in the field of network security. NSSA fully integrates network security elements and comprehensively utilizes the characteristics of traditional detection tools to accurat...
