Within the European Union, several initiatives are underway, aiming to motivate, regulate and eventually orchestrate the establishment of capacity and enhancement of situational awareness, incident response, and preparedness capabilities, with an expected emphasis on operators of essential services and state actors entrusted with cybersecurity. In this context, the institution of cooperation and information exchange channels to allow for coordinated cross-border responses to large-scale incidents is particularly prioritized. Motivated by the above, this work presents a conceptual blueprint in support of architecting and establishing interoperable Cyber Security Operations Centres that combine capacity for situational awareness, incident response, and preparedness, also benefiting from the interplay between them, ultimately enhancing national cybersecurity capabilities, cross-border collaboration, and national supervision of their critical sectors, in line with current and upcoming regulatory requirements and the ever-increasing need for national and international cooperation.This work has received funding from the European Union’s Connecting Europe Facility (CEF) programme under Grant Agreement No. INEA/CEF/ICT/A2020/2373266 (JCOP project) and the Horizon Europe programme under Grant Agreement No. 101070586 (PHOENi2X project).http://creativecommons.org/licenses/by/4.0/2601-26092022 IEEE International Conference on Big DataProceedings - 2022 IEEE International Conference on Big Data, Big Data 2022 Fysarakis Konstantinos Φυσαρακης Κωνσταντινος Mavroeidis, Vasileios 1986- Athanatos Manos Αθανατος Μανος Spanoudakis, George Ioannidis Sotirios Ιωαννιδης Σωτηριος Institute of Electrical and Electronics Engineers Security operations centre Interoperability Cybersecurity standardisation Cyber threat intelligence Security playbooks Situational awareness Incident response Preparedness Cyber range NIS2 CSIRTs network EU CyCLONe
