Until now, in most organizations, physical access systems and logical security systems have operated as two independent elements, and have been managed by completely separate departments. The lack of interoperability between the two sectors often resulted in a security hole of the overall infrastructure. An attacker who has physical access can not only steal a PC or confidential data, but can also compromise network security. Therefore, a combination of physical and logical security definitively allows for a more effective protection of the organization. In this work we present a correlation system which aims at bringing a significant advancement in the convergence of physical and logical security technologies. By “convergence” we mean effective cooperation (i.e. a coordinated and results-oriented effort to work together) among previously disjointed functions. The holistic approach and enhanced awareness technology of our solution allows dependable (i.e. accurate, timely, and trustworthy) detection and diagnosis of attacks. This ultimately results in the achievement of two goals of paramount importance, and precisely guaranteeing the protection of citizens and assets, and improving the perception of security by citizens. The effectiveness of the proposed solution is demonstrated in a scenario that deals with the protection of a real Critical Infrastructure. Three misuse cases have been implemented in a simulation environment in order to show how the correlation system allows for the detection of different attack patterns.
