Enforcing Architectural Security Decisions
Stefanie Jasser
Abstract
Software architects should specify security measures for a software system on an architectural level. However, the implementation often diverges from this intended architecture including its security measures. This may lead to severe vulnerabilities that have a wide impact on the system and are hard to fix afterwards. In this paper, we propose an approach for checking the implementation's conformance with the defined security measures using architectural security rules: We extend a controlled natural language approach to formalize these rules and use dynamic analysis techniques to extract information on the actual system behavior for the conformance check. We evaluate our approach by an industrial case study to show the applicability and flexibility of our conformance checking approach.
