为了保证大规模特定域网络系统的安全性和健壮性,基于风险评估的主动防御技术是目前研究的主流。风险评估是针对大规模特定域网络系统防护的关键技术之一。网络风险分析和评估是一个复杂的过程,一个完善的安全风险评估架构应该具备相应的标准体系、技术体系、业务体系和法律法规。目前,针对风险评估架构中相关技术和方法的国内外研究工作很多,下面从不同的角度对一些有代表性的相关研究工作进行综述和分析。
In order to ensure the security and robustness of large-scale domain-specific network systems, active defense technology based on risk assessment is the mainstream of current research. Risk assessment is one of the key technologies for the protection of large-scale domain-specific network systems. Network risk analysis and evaluation is a complicated process. A sound security risk assessment framework should have the corresponding standard system, technical system, business system and laws and regulations. At present, there are a lot of domestic and foreign researches on the related technologies and methods in the risk assessment framework, and the following are some of the relevant research work from different perspectives for review and analysis.
