A Tool for Managing Evolving Security Requirements

Management of requirements evolution is a challenging process. Requirements change continuously making the traceability of requirements difficult and the monitoring of requirements unreliable. Moreover, changing requirements might have an impact on the security properties a system design should satisfy: certain security properties that are satisfied before evolution might no longer be valid or new security properties need to be satisfied after changes have been introduced. This paper presents SeCMER, a tool for requirements evolution management developed in the context of the SecureChange project. The tool supports automatic detection of requirement changes and violation of security properties using change-driven transformations. The tool also supports argumentation analysis to check security properties are preserved by evolution and to identify new security properties that should be taken into account.
