National Cybersecurity Strategy tracting authorities; it supervises on fiduciary services, certified e-mail operators, accredited digital documents registries, as well as on public and private entities that participate in the Public System of Digital Identity (SPID). Fundamental and determining input is provided by the Public Administrations which are members of the various interministerial fora, among which the National CyberSecurity Cell (NCS) is particularly relevant. As an inter-ministerial coordination forum, established within the National Cybersecurity Agency, which operates in support of the Prime Minister for the aspects related to the prevention and preparation to eventual crisis and for the activation of the alerting procedures, the NCS can facilitate, in particular, the achievement of goal no. 2. Indeed, the NCS ensures the alignment between ACN, the Military Advisor of the Prime Minister, the Intelligence, the Ministry of Foreign Affairs and International Cooperation, the Ministry of Interior, the Ministry of Justice, the Ministry of Defence, the Ministry of Economy and Finance, the Ministry of Economic Development, the Ministry of Ecological Transition, the Ministry of Sustainable Infrastructures and Mobility, the Ministry of University and Research, the Department for Digital Transformation. At the same time, the NCS, which has the function of proposing cybersecurity initiatives, is also a platform where to discuss the various initiatives with impacts on cybersecurity policies promoted by the Administrations and it can, as such, represent the principal forum where the coordinated development of initiatives related to goals no. 1 and 3 can be ensured. In this context, other interested subjects, including private entities, can be invited to participate. Still in the context of inter-institutional coordination, besides the NCS, other fora where the strategic goals can be reached, in particular the protection one, are represented by the Interministerial Board for the implementation of the National Security Perimeter for Cyber as well as, once established, by the Technical Coordination Committee provided by the NIS Decree. On the private side, the business operators, the university and research and, last but not least, civil society, represent essential elements for the resilience of the Country and are, therefore, an essential part of the national cybersecurity ecosystem. In this respect, also through the fundamental stimulus and contribution of ACN and based on its functions provided by the law, a continuous collaboration between the aforementioned Public Administrations, universities, research entities and private operators (also through trade associations) shall be searched and supported, through specific understandings and agreements. This in order to guarantee a fruitful interaction both with the entities who manage strategic ICT assets and the entire business sector, including SMEs and start-ups. An example of a fruitful public-private collaboration is the National Framework for Cybersecurity and Data Protection, drafted by the CIS-Sapienza and by the National Interuniversity Consortium for Informatics. The Framework provides a cross-cutting and size-regardless applicable methodology, by public and private organizations, aimed at supporting cybersecurity and assets protection-oriented initiatives to reduce vulnerabilities and risks to which such organizations are exposed to. The document is periodically updated and integrated to ensure a full adherence to the most recent sectorial legislation, the General Data Protection Regulation (GDPR), the Cybersecurity Act and measures on supply chain’s security. 32
