Service-Oriented Security Architecture for CII based on Sensor Networks

Abstract

The extraordinary growth of the information society is originating a high dependency on ICT. This provokes that those strongly interrelated technological infrastructures, as well as the information systems that underpin them, become highly critical, since their disruption would lead to high economical, material and, sometimes, human loss. As a consequence, the protection of these critical information infrastructures is becoming a major objective for governments and companies. In this paper, we give an overview of the main challenges and open research issues on critical information infrastructure security, and introduce an on-going research project that, using wireless sensor networks as an underlying technology, is dealing with those problems. Our research project focuses on the development of protection, control, evaluation, maintenance and verification mechanisms, integrated into a secure service-oriented architecture
