CHAPTER II – The European Cybersecurity Alert System (Art. 3-9)
Art. 3 Cyber Solidarity Act - Establishment of the European Cybersecurity Alert System
Art. 4 Cyber Solidarity Act - National Cyber Hubs
Art. 5 Cyber Solidarity Act - Cross-Border Cyber Hubs
Art. 6 Cyber Solidarity Act - Cooperation and information sharing within and between Cross-Border Cyber Hubs
- Members of a Hosting Consortium shall ensure that their National Cyber Hubs share, in accordance with the written consortium agreement referred to in Article 5(3), relevant information, anonymised where appropriate, such as information relating to cyber threats, near misses, vulnerabilities, techniques and procedures, indicators of compromise, adversarial tactics, threat-actor-specific information, cybersecurity alerts and recommendations regarding the configuration of cybersecurity tools to detect cyberattacks, among themselves within the Cross-Border Cyber Hub where such information sharing:
- fosters and enhances the detection of cyber threats and reinforces the capabilities of the CSIRTs network to prevent and respond to incidents or to mitigate their impact;
- enhances the level of cybersecurity, for example through raising awareness in relation to cyber threats, limiting or impeding the ability of such threats to spread, supporting a range of defensive capabilities, vulnerability remediation and disclosure, threat detection, containment and prevention techniques, mitigation strategies, response and recovery stages or promoting collaborative threat research between public and private entities.
- The written consortium agreement referred to in Article 5(3) shall establish:
- a commitment to share among the members of the Hosting Consortium information as referred to in paragraph 1 and the conditions under which that information is to be shared;
- a governance framework clarifying and incentivising the sharing by all participants of relevant information, anonymised where appropriate, as referred to in paragraph 1;
- targets for contribution to the development of advanced tools and technologies, such as artificial intelligence and data analytics tools.
The written consortium agreement may specify that the information referred to in paragraph 1 is to be shared in accordance with Union and national law.
- Cross-Border Cyber Hubs shall conclude cooperation agreements with one another, specifying interoperability and information-sharing principles among the Cross-Border Cyber Hubs. Cross-Border Cyber Hubs shall inform the Commission about the cooperation agreements concluded.
- Information sharing as referred to in paragraph 1 between Cross-Border Cyber Hubs shall be ensured by a high level of interoperability. To support such interoperability, ENISA shall, in close consultation with the Commission, without undue delay and in any event by 5 February 2026, issue interoperability guidelines specifying in particular information-sharing formats and protocols, taking into account international standards and best practices, as well as the functioning of any established Cross-Border Cyber Hubs. Interoperability requirements provided for in the cooperation agreements of Cross-Border Cyber Hubs shall be based on the guidelines issued by ENISA.
