Toward an Ontology Architecture for Cyber-Security Standards.
Mary C. Parmelee · 2010
Abstract. The rapid growth in magnitude and complexity of cyber-security information and event management (CSIEM) has ignited a trend toward security automation and information exchange standards. Making Security Measurable (MSM) references a collection of open community standards for the common enumeration, expression and reporting of cyber-security-related information. While MSM-related standards are valuable for enabling security automation; insufficient vocabulary management and data interoperability methods as well as domain complexity that exceeds current representation capabilities impedes the adoption of these important standards. This paper describes an Agile, ontology architecture-based approach for improving the ability to represent, manage, and implement MSM-related standards. Initial cross-standard analysis revealed enough common concepts to warrant four ontologies that are reusable across standards. This reuse will simplify standards-based data interoperability. Further, early prototyping enabled us to streamline vocabulary management processes and demonstrate the ability to represent complex domain semantics in OWL ontologies.
