构建主动式认知网络安全管理模型探究

摘要

目前网络安全管理以被动防御为主，面对复杂外部环境、多种安全需求和受限能力与资源等因素，安全策略不能对环境变化做出及时的反应。针对这一问题，提出一种认知网络安全管理模型（网络实体主动感知网络环境），及时分析安全威胁，利用安全策略知识库构建安全策略。该模型增强了网络的安全性和灵活性，提高了网络应对复杂环境的生存能力，为网络安全管理提供了一种动态模型。%The main management of network security is passive defense, with which a network manager predicting the network security to set a feasible security strategy.However,current schemes are not suit-able to the networks because of complex environment,various security requirements and limited capability and resources.To solve the problem,it put forward a novel model ( cognitive network security management model,CNSMM) ,which can sense network environment,analysis security threats,construct security strat-egies in this paper.This model not only strengthens the network security and flexibility,but also improves the survival capability.
