随着信息技术的发展,信息安全问题越来越严重,信息安全风险评估成为风险管理的重要手段.本文设计了一套采用定性量化方法计算风险的评估系统,论文主要阐述了系统的数据库模型和功能结构,最后对系统的优点进行了分析.使用该系统可以用数字指标来准确评估系统的风险,具有很强的实际使用价值.,With the development of information technology, information security problems have become increasingly serious and information security risk assessment has ted into an important mean of risk management. In this paper, we designed a risk assessment system using qualitative and quantified analysis method to calculate the risk. This paper mainly expatiated the system’s database model and functional structure, and analyzed the advantages of the system at the last. The risk of system can be calculated accurately with numerical indicators by using this system. This system has strong practical value.
