INSPIRE Ontology Handler: Automatically building and managing a knowledge base for Critical Information Infrastructure protection

In current Critical Information Infrastructures, cyber-attackers can remotely leverage complex interdependencies with the underlying communication systems to cause large damages. Assessing the vulnerabilities of such systems and identifying potential countermeasures are crucial functionalities for their protection. This paper presents the INSPIRE Ontology Handler, a standard-based tool that enables automatic audits of the security and criticality level of information systems. It is composed of an infrastructure discovery component aiming at automatically discovering assets, an ontology repository to store and manipulate instantiated ontologies, and a visualization component to graphically view and modify information stored within ontologies.
