The disruption of communications in critical infrastructures could have a serious impact on the health, safety, security or economic well-being of citizens or even prevent the effective functioning of governments or other agencies. For this reason, in this paper we present a distributed architecture, named CYBERSENS, aimed at preventing, early detecting, and mitigating cyber attacks to critical infrastructure networks. CYBERSENS is an advanced IDS/IPS system specially tailored for securing communications in critical infrastructures. It's federated architecture, the combination of misuse detection techniques and novel anomaly detection approaches, and the inclusion of mechanisms for self-obfuscation and self-protection, makes our proposal specially suitable for these scenarios.
The SCOUT project is based on the use of multiple innovative and low impact technologies for the protection of space control ground stations and the satellite links against physical and cyber-attacks, and for intelligent reconfiguration of the ground station network (including the ground node of the satellite link) in the case that one or more nodes fail. The SCOUT subsystem devoted to physical attacks protection, SENSNET, is presented. It is designed as a network of sensor networks that combines DAB and DVB-T based passive radar, noise radar, Ku-band radar, infrared cameras, and RFID technologies. The problem of data link architecture is addressed and the proposed solution described.
