语言评估算子计算信息安全的风险

A risk analysis of an electronic commerce system based on consumer's knowledge of security requirements

为提高电子商务系统安全性,对系统存在的风险进行全面的识别和评价,从用户的视角对电子商务系统的风险进行定量描述,使风险分析过程更具针对性。在用户安全需求知识的基础上确定系统安全需求项,利用基于语言评估标度的算子来计算风险系数,进而预测出事故代价,而风险则为事故发生的可能性和事故代价的乘积,最后通过给出实例验证了方法的有效性和科学性,为进一步从用户的角度研究电子商务的风险奠定了基础。

In order to improve the security of e-commerce systems, comprehensive identification and evaluation of on the knowledge of security requirements that users possessed. We took advantage of the operator based on a language assessment scale to calculate the risk factor. We also forecast the cost of the accident. Risk is the product of the accident possibility and the cost of accident. The effectiveness of the method was verified with an example. This work lays the foundation for further research on the risks of e-commerce, from the point of view of users.
