Industrial systems are nowadays exposed to new kinds of malicious threats. The cause of this is related to the large number of new vulnerabilities and architectural weaknesses introduced by the extensive use of ICT and networking technologies for the operation and monitoring of such complex systems. Several scientific works, have showed how supervisory control and data acquisition systems (SCADA), i.e. the systems which control industrial installations, are exposed to cyber attacks. These, due to the intrinsic nature of SCADA systems, cannot be avoided by using traditional ICT security measures. In this paper, we present a first prototype of survivable SCADA architecture, conceived in order to be resilient and robust to cyber SCADA attacks.
