Problems solved by technology

The traditional network security situational awareness analysis method only focuses on the analysis of the correctness of information fusion, and has the disadvantages of being difficult to fully explore the changing laws of the network security situation and insufficient intuition for the development of the security situation.

Embodiment Construction

[0022] In one embodiment, a cyberspace security situational awareness analysis method, such as figure 1 shown, including the following steps:

[0023] Step S110: Receive the security situation time series obtained by analyzing the cyberspace security situation data.

[0024] Cyberspace security situation data can be obtained in advance and analyzed to obtain a security situation time series for storage for subsequent data analysis. Specifically, the security situation data may include topology node information, vulnerability information, system logs and traffic, etc. There is not only one way to analyze cyberspace security situation data. It can be transformed into a security situation time series representing the comprehensive security situation of cyberspace through various situation fusion algorithms{x i}.

[0025] Step S120: Divide the security situation time series into security status levels to obtain the security situation status symbol time series.

[0026] The sec...

Abstract

The invention relates to a cyberspace security situation awareness analysis method and system. Sufficient mining analysis of a security situation time sequence is carried out; a directed weighted network representing a security situation state change rule is constructed; the directed weighted network is analyzed, so that attribute data is obtained; therefore, the security situation change rule contained in cyberspace security situation data is analyzed effectively; the problem that analysis on existing data statistical modelling currently is limited can be made up; the network security situation change rule is sufficiently mined; furthermore, the network security situation can be reflected intuitively; support is provided for high-speed decision of network managers; and thus, the network can be relatively safe and effective.

Description

technical field [0001] The invention relates to the field of electronic information technology, in particular to a cyberspace security situation awareness analysis method and system. Background technique [0002] Cyberspace (cyberspace) is a complex digital society that supports information interaction based on computer, data communication and other technologies. . Cyberspace security management is critical to the safe operation of national infrastructure. Situational awareness refers to the technology of acquiring, understanding, displaying and predicting future development trends of security elements that can cause system state changes in a large-scale system environment. In the analysis of cyberspace security situational awareness, how to build a security situational analysis model to analyze the law of situational changes and predict the development trend of the security situation is the key to situational awareness technology. [0003] The traditional network securit...
