Abstract

The invention discloses a network security index calculation method. The method comprises: quantifying network events that qualitatively describe network states, defining the network events as abnormal events and secure events, determining the number of the abnormal events and / or secure events in a network event system and the risk grade of each event by means of an event set, calculating an event grade index, finally calculating a network security index according to an event scale index and the event grade index so as to obtain a description of explaining system stability. The method can converts describe network qualitative description into quantitative description so as to reflect the basic fact of the network security state.

Description

technical field

[0001] The invention belongs to the technical field of computer information security, and relates to a comprehensive network supervision quantitative description method oriented to an e-government intranet, in particular to a calculation method for quantifying the security degree of a system environment based on event sets collected by network security monitoring. Background technique

[0002] With the increasing scale of the e-government intranet, the work of comprehensive monitoring of the network and ensuring information security is becoming increasingly complex.

[0003] In order to be able to fully perceive what is happening on the intranet, especially the security situation, the relevant management departments have adopted many network management tools to monitor and manage the network.

[0004] In the application scenario of network monitoring, network security administrators need to have qualitative and quantitative descriptions of the network securit...
