| 摘 要： | 提出一种改进的信息系统可生存需求分析框架ISNA(improved SNA). 在组件式开发模型中选择合适模型作为分析基础,避免了SNA(survivable network analysis)只能建立在重量级螺旋模型上的弊端. 增加可生存测试和故障攻击库等反馈措施有效解决需求的多变性问题,保障完备性. 最后用一个小型电子商务系统实例论证了ISNA能够更好地指导和改进系统设计和实现,增加系统的可生存能力.

| Abstract: | An improved survivable network requirement analysis framework (ISNA) is proposed. It is required to choose the best suitable software development model as the framework basement from the component-oriented set, which avoids SNAs shortcoming with only one choice of heavy model named spiral. The feedback components, an embedded survivable test and fault-attack library, fix the requirements variability and guarantee its integrity. At last, we analyzed an e-business website with ISNA, proving that ISNA performs better at guiding systems implementation and improving its survivability. |
