Tiivistelmä
Securing an electricity distribution network is equally crucial to securing other critical infrastructure (CI) components. Many critical infrastructure components are operating and controlling by Supervisory Control and Data Acquisition (SCADA) systems. Very SCADA system is also controlling the power network. In the modern infrastructure, these SCADA controlled systems are connecting to standard corporate networks for various reasons. Critical infrastructure and SCADA systems require higher resilient communication channels compared to the corporate network. This infrastructure and the system also demand equally high level of security along with a corporate network. Organizations must use standard base network as a part of solution in order to have resilient communications networks. These combined networks such as TETRA, 3G, LTE, ADSL and satellite have varied level of bandwidth and built-in security features. Recently the additional feature such as a live video stream transported on the critical infrastructure and SCADA networks. These data are transporting in the same logical communications channels without disturbing the SCADA command traffic. This paper aims to propose a new model to combine these networks to produce a highly resilient and secure communications network. The proposed communication system is built-on the Distributed Systems intercommunication Protocol (DSiP) that combines the contradicting requirements to a uniform and easily maintained system. The same requirements apply to ‘Multi-Agency Cooperation in Cross-border Operations (MACICO)’ project, part of an International Celtic Plus project. The proposed DSiP system is reusable for various needs and is adaptable to future network technologies.
