Network vulnerability identification method based on removal of timing sequence

Abstract

The invention provides a network vulnerability identification method based on removal of a timing sequence. The method comprises the following steps of 1, pre-processing network data; 2, defining a network vulnerability measurement index; 3, identifying a network key node set; and 4, optimizing a node removal timing sequence. According to the method provided by the invention, the total quantity of network attack nodes is reduced in space, sensitivity of early network attacks is improved in time, an intentional network attack effect is optimized, and thus network attack efficiency and capacity are improved in general.

Description

technical field [0001] The present invention proposes a network vulnerability identification method based on timing removal, which is used to quickly reduce network reliability and control various propagation processes on the network; the opposite angle can also be used to identify network vulnerabilities and find critical infrastructure networks (such as transportation network, power network, communication network, etc.) to reduce the vulnerability of the network, which belongs to the interdisciplinary field of reliability and network science. Background technique [0002] With the rapid development of information technology, the network, as the link of physical entity structure connection and functional interaction, is ubiquitous in real life. The spread of harmful information flow on the network will cause great damage to the network as a whole. The importance of flow control has also become increasingly prominent. In 2015, a certain company was affected by rumors on onl...

Problems solved by technology

This kind of adaptive method mainly considers the information changes of the network between the previous and next neighbor time steps. For the entire removal process, the adaptive method can only reflect local time information, so the effect is limited.
