Making secure a software system is a very critical purpose, especially because it is very hard to consolidate an exhaustive body of knowledge about security risks and related countermeasures. To define a technological infrastructure for exploiting this knowledge poses many challenges. This paper introduces a system to capture, share and reuse software security knowledge within a Software Organization. The system collects knowledge in the form of misuse cases and makes use of Case Based Reasoning for implementing knowledge management processes. A reasoned analysis of the system was performed throughout a case study, in order to identify weaknesses and opportunities of improvement.
