The invention provides a network security situation assessment method and system, and the method comprises the following steps: building network security situation indexes which comprise a first-level index and a second-level index; risk evaluation is carried out on the secondary indexes, a first characteristic value is obtained based on a risk evaluation result, a risk evaluation result of the primary indexes is obtained through the first characteristic value, a second characteristic value is obtained based on the risk evaluation result of the primary indexes, and the second characteristic value is used for representing the risk of the primary indexes; and establishing a neural network model and performing training, and inputting the second feature value into the trained neural network model, thereby obtaining a network security situation assessment result.
Description
technical field [0001] The invention relates to the technical field of network security, in particular to a network security situation assessment method and system. Background technique [0002] The Internet is a product of the information age and currently covers almost all important areas in the world. With the continuous expansion of network scale, network attacks and destructive behaviors are becoming more frequent, and the network security situation is becoming increasingly severe. In order to form a network security proactive protection capability, it is first necessary to understand the internal and external threats of the network and the overall security status. The network security situation assessment technology conducts in-depth comprehensive processing and analysis of factors affecting security in the network, evaluates the overall security status of the network in real time, and provides guidance for network security management command and decision-making. The...
