A network security measurement method, device and system

Abstract

The invention provides a network security measuring method, a network security measuring device and a network security system. A monitoring object in a network has at least one security measuring index. The method comprises an acquisition step in which the value of each of measuring parameters corresponding to the security measuring indexes of the monitoring object is acquired, a first calculation step in which a first security measuring value of each security measuring index is calculated according to the value of the measuring parameter corresponding to the security measuring index, a fuzzification step in which the first security measuring values of the security measuring indexes corresponding to the monitoring object is fuzzified by constructing a membership function to obtain a fuzzy evaluation matrix, a weight establishment step in which the importance weight of each security measuring index to the monitoring object is determined through a Delphi method and a weight set of all importance weights is established, and a second calculation step in which the fuzzy evaluation matrix is multiplied by the weight set to obtain second security measuring values of the monitoring object. By adopting the scheme, the security of the network can be measured comprehensively and reasonably.

Description

technical field [0001] The invention relates to the field of network security, in particular to a network security measurement method, device and system. Background technique [0002] With the development of computer technology and communication technology, hidden dangers of network security are increasingly exposed, various criminal activities against the network emerge in an endless stream, and network information is completely facing huge risks. In order to have a clear understanding of the degree of threat faced by the computer network, so as to take corresponding network security precautions and minimize various losses caused by network security, it is an important research topic at present. [0003] Network security evaluation is the basis for formulating and adjusting network security strategies, and effective network security protection strategies can only be formulated based on accurate evaluation results. [0004] At present, based on network intrusion events, the...
