Security requirements analysis using knowledge in CAPEC

Because all the requirements analysts are not the experts of security, providing security knowledge automatically is one of the effective means for supporting security requirements elicitation. We propose a method for eliciting security requirements on the basis of Common Attack Patterns Enumeration and Classification (CAPEC). A requirements analyst can automatically acquire the candidates of attacks against a functional requirement with the help of our method. Because technical terms are mainly used in the descriptions in CAPEC and usual phrases are used in the requirements descriptions, there are gaps between them. To bridge the gaps, our method contains a mapping between technical terms and noun phrases called term maps.
