Abstract

We first consider network security services and then review threats, vulnerabilities and failure modes. This review is based on standard texts, using well-known concepts, categorizations, and methods, e.g. risk analysis using asset-based threat profiles and vulnerability profiles (attributes). The review is used to construct a framework which is then used to define an extensible ontology for network security attacks. We present a conceptualization of this ontology in figure 1. Keywords: network, cyber, security, ontology, attack, threat, vulnerability, failure.
