Cybersecurity in the Energy sector and relevant information sharing is at the foremost of European strategy towards the digital decade targeted by the EC for the years to come. The proposed Pan-European Incidents Information Sharing Platform (I2SP) offers a cyber-shield armour to European Electrical Power and Energy Systems (EPES) enabling cooperative detection of large scale, cyber-human security and privacy incidents and attacks. Via Incidents Information Sharing Platform, early detection and appropriate mitigation, guarantees the continuity of operations and minimization of cascading effects in the infrastructure itself, the environment, the citizens and the end-users.The Incidents’ Information Sharing Platform (I2SP) constitutes the software package which enables secure Cyber-Threat Intelligence (CTI) information sharing among EPES participants, as well as with trusted nominated entities, such as Information Sharing and Analysis Centers (ISACs), Computer Security Incident Response Teams (CSIRTs) and Security Operations Centers (SOC). I2SP facilitates technical information sharing in view of a warning system and incident reporting across the EU, aligning with the pillars of the new Network Code on Cybersecurity.
