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 SNAs shortcoming with only one choice of heavy model named spiral. The feedback components, an embedded survivable test and fault-attack library, fix the requirements variability and guarantee its integrity. At last, we analyzed an e-business website with ISNA, proving that ISNA performs better at guiding systems implementation and improving its survivability.
