A view of trust and information system security under the perspective of critical infrastructure protection

Although trust is recognized as important in security issues of computer networking environments, few studies on information systems deal with both trust and security, and those existing tend to remain within the short perimeter of two-agent interactions. We propose to rethink trust research on information system security by considering the holistic approach of critical infrastructure protection (CIP). After introducing the problem, we give the definitions that are necessary for a common understanding of the concepts of critical infrastructures and trust. Some works on critical infrastructure protection involving information systems are then described briefly. Finally, we present our transdisciplinary view of trust research on information system security under the perspective of CIP.
