Ontology-Based Scenario Modeling for Cyber Security Exercise

Abstract

The growing demand for cyber security professionals with practical knowledge is boosting the development and conduct of cyber security exercises around the world. Scenarios stand a central position of the exercise, which sets the stage for later action by providing contextual information that the participants will need during the exercise. To manage the increasing numbers of scenario creation in the different contexts, we propose an ontology to model scenarios for cyber security exercises. This ontology identifies aspects of scenario modeling relevant to cyber security that can be used as a means to achieve a defined taxonomy of knowledge items and a standard vocabulary for cyber scenarios. With the semantic framework based on RDF/OWL, this ontology provides a common structure at a semantic level that allows scenarios to be shared and reused across applications and community boundaries. In this paper, we present the design, implementation, and evaluation of the proposed ontology.
