4. Characterization of the minimal amount of information necessary for the survival of the CIs communication

In order to estimate and characterize the minimum amount of information necessary for the survival of the CIs communication we have simulated scenarios representing the situation around the CG maritime traffic. In this technical report we have determined the European Critical Infrastructures (ECIs) and Controlling Governmental Agencies (CGAs) individuated in the Italian Ministry of Infrastructure and Transport. We have chosen the transport sector and, in particular, the sea transport. In the frame of the SWING project the Coast Guard has been identified as ECI and the General Command as CGA, both under the control of the Ministry of Infrastructures and Transport. We have also studied the organization of these infrastructures in Italy, Spain and Greece and we have realized that all the CGs have approximately the same functions. For what concerns Spain and Greece CGs, we have obtained information on the organization, functions and activities by visiting the respective websites. Whereas for what concerns the CGA, the General Command in Rome has been contacted for an interview. A series of questions have been formulated and their answers reported. We have simulated three Coast Guards in the three Mediterranean ports of Pireo, Palermo and Barcellona (ECIs) and only one CGA located in Rome in the Comando Generale (CDO), that manages and controls all the three Cost Guards. In our simulated scenario concerning the maritime traffic we referred to an AIS system able to control the vessels in a particular area controlled by AIS-VTS stations by means of VHF transponders. The information is up-linked directly by AIS-VTS system in the Operative Room of the CDO. Each vessel contacted by the AIS-VTS contributes approximately with a kbit of data. These amount of information must be elaborated and transferred to the CGs because they are mainly interested in the traffic in their maritime area and other information concerning the safety of the infrastructure. These essential data/voice communications are necessary for management and control of ECIs and reduced data flow is necessary for the HF back-up network, avoiding to waste precious time. Even if the HF network system has scarce efficiency, it is the only way to communicate relatively short messages, necessary for infrastructures awareness, preparedness and protection, between OR-CDO and CGs at long distances, at any time and any condition.
