The NIS2 Directive establishes a regulatory framework aimed at encouraging the responsible and timely disclosure of cybersecurity vulnerabilities in ICT products and services within the European Union.

This framework fosters collaboration between those who discover vulnerabilities and the organizations responsible for resolving them.

Creating a network of coordinators

The NIS2 Directive requires each Member State to designate one of its Computer Security Incident Response Teams (CSIRTs) as a coordinator for vulnerability disclosure. This designated CSIRT plays a crucial role in facilitating the coordinated vulnerability disclosure process.

The role of designated CSIRTs

• Trusted intermediary: The designated CSIRT acts as a bridge between the person reporting a vulnerability and the ICT manufacturer or provider involved. Its role helps build trust and ensures the proper sharing of information.
• Facilitation and support: The CSIRT assists in reporting vulnerabilities, offering guidance and help throughout the process. This is useful for those unfamiliar with disclosure procedures.
• Coordination and communication: If a vulnerability involves multiple parties or has cross-border impacts, the CSIRT coordinates communication. This ensures a rapid and effective response.

Key elements of coordinated vulnerability disclosure

The NIS2 Directive defines several key aspects of the coordinated vulnerability disclosure process:

• Anonymous reporting: The Directive allows for the anonymous reporting of vulnerabilities, recognizing that some individuals or organizations may be reluctant to reveal their identity for fear of retaliation.
• Timely disclosure: The regulatory framework emphasizes the importance of timely disclosure, striking a balance between giving vendors the time needed to resolve vulnerabilities and protecting users from potential threats.
• Responsible disclosure: The process encourages responsible disclosure, meaning that vulnerabilities are reported to the appropriate parties in a way that minimizes risks and avoids unnecessary public disclosure.

European cybersecurity vulnerability database

To support the coordinated disclosure framework, the NIS2 Directive provides for the creation of a European vulnerability database. This database serves as a central repository for publicly known vulnerabilities in ICT products and services.

The EU cybersecurity vulnerability database is designed to:

• Increase transparency and awareness regarding known vulnerabilities.
• Facilitate timely resolution by providing information on available patches and mitigation measures.
• Strengthen the EU’s collective cybersecurity posture by improving vulnerability management practices.

NIS2 against cybersecurity vulnerabilities

The NIS2 Directive promotes a cybersecurity culture by encouraging responsible vulnerability disclosure and collaboration among stakeholders. Through the establishment of a clear framework and the provision of support mechanisms, the Directive aims to create an environment where vulnerabilities are identified and addressed quickly, contributing to a more secure digital landscape for EU businesses and citizens. For organizations that need to evaluate what the main objective of the NIS2 Directive is and how to translate it into concrete obligations, starting a structured NIS2 compliance path is the most effective way to turn these regulatory requirements into real operational measures.
