6. Toward a Security Core Ontology

In this chapter we provide definitions of security concepts and relations between them as used in this book. On the one hand these are required as many different definitions are used in security literature. A clarification of the relations between the concepts helps to get a better understanding of the overall concept “security”. On the other hand the development of such a “security ontology” enables the automated processing of security-related information. As such, we consider a security ontology as an important prerequisite for specifying security patterns and improve their applications in the security domain.
