NIS 2 Directive

Given the intensification and increased sophistication of cyber threats, Member States should strive to ensure that entities that are excluded from the scope of this Directive achieve a high level of cybersecurity and to support the implementation of equivalent cybersecurity risk-management measures that reflect the sensitive nature of those entities.

For the purpose of achieving and maintaining a high level of cybersecurity, the national cybersecurity strategies required under this Directive should consist of coherent frameworks providing strategic objectives and priorities in the area of cybersecurity and the governance to achieve them. Those strategies can be composed of one or more legislative or non-legislative instruments.

Cyber hygiene policies provide the foundations for protecting network and information system infrastructures, hardware, software and online application security, and business or end-user data upon which entities rely. Cyber hygiene policies comprising a common baseline set of practices, including software and hardware updates, password changes, the management of new installs, the limitation of administrator-level access accounts, and the backing-up of data, enable a proactive framework of preparedness and overall safety and security in the event of incidents or cyber threats. ENISA should monitor and analyse Member States’ cyber hygiene policies.

Cybersecurity awareness and cyber hygiene are essential to enhance the level of cybersecurity within the Union, in particular in light of the growing number of connected devices that are increasingly used in cyberattacks. Efforts should be made to enhance the overall awareness of risks related to such devices, while assessments at Union level could help ensure a common understanding of such risks within the internal market.

Open-source cybersecurity tools and applications can contribute to a higher degree of openness and can have a positive impact on the efficiency of industrial innovation. Open standards facilitate interoperability between security tools, benefitting the security of industrial stakeholders. Open-source cybersecurity tools and applications can leverage the wider developer community, enabling diversification of suppliers. Open source can lead to a more transparent verification process of cybersecurity related tools and a community-driven process of discovering vulnerabilities. Member States should therefore be able to promote the use of open-source software and open standards by pursuing policies relating to the use of open data and open-source as part of security through transparency. Policies promoting the introduction and sustainable use of open-source cybersecurity tools are of particular importance for small and medium-sized enterprises facing significant costs for implementation, which could be minimised by reducing the need for specific applications or tools.

Utilities are increasingly connected to digital networks in cities, for the purpose of improving urban transport networks, upgrading water supply and waste disposal facilities and increasing the efficiency of lighting and the heating of buildings. Those digitalised utilities are vulnerable to cyberattacks and run the risk, in the event of a successful cyberattack, of harming citizens at a large scale due to their interconnectedness. Member States should develop a policy that addresses the development of such connected or smart cities, and their potential effects on society, as part of their national cybersecurity strategy.

In recent years, the Union has faced an exponential increase in ransomware attacks, in which malware encrypts data and systems and demands a ransom payment for release. The increasing frequency and severity of ransomware attacks can be driven by several factors, such as different attack patterns, criminal business models around ‘ransomware as a service’ and cryptocurrencies, ransom demands, and the rise of supply chain attacks. Member States should develop a policy addressing the rise of ransomware attacks as part of their national cybersecurity strategy.

Public-private partnerships (PPPs) in the field of cybersecurity can provide an appropriate framework for knowledge exchange, the sharing of best practices and the establishment of a common level of understanding among stakeholders. Member States should promote policies underpinning the establishment of cybersecurity-specific PPPs. Those policies should clarify, inter alia, the scope and stakeholders involved, the governance model, the available funding options and the interaction among participating stakeholders with regard to PPPs. PPPs can leverage the expertise of private-sector entities to assist the competent authorities in developing state-of-the-art services and processes including information exchange, early warnings, cyber threat and incident exercises, crisis management and resilience planning.

Member States should, in their national cybersecurity strategies, address the specific cybersecurity needs of small and medium-sized enterprises. Small and medium-sized enterprises represent, across the Union, a large percentage of the industrial and business market and often struggle to adapt to new business practices in a more connected world and to the digital environment, with employees working from home and business increasingly being conducted online. Some small and medium-sized enterprises face specific cybersecurity challenges such as low cyber-awareness, a lack of remote IT security, the high cost of cybersecurity solutions and an increased level of threat, such as ransomware, for which they should receive guidance and assistance. Small and medium-sized enterprises are increasingly becoming the target of supply chain attacks due to their less rigorous cybersecurity risk-management measures and attack management, and the fact that they have limited security resources. Such supply chain attacks not only have an impact on small and medium-sized enterprises and their operations in isolation but can also have a cascading effect on larger attacks on entities to which they provided supplies. Member States should, through their national cybersecurity strategies, help small and medium-sized enterprises to address the challenges faced in their supply chains. Member States should have a point of contact for small and medium-sized enterprises at national or regional level, which either provides guidance and assistance to small and medium-sized enterprises or directs them to the appropriate bodies for guidance and assistance with regard to cybersecurity related issues. Member States are also encouraged to offer services such as website configuration and logging enabling to microenterprises and small enterprises that lack those capabilities.

As part of their national cybersecurity strategies, Member States should adopt policies on the promotion of active cyber protection as part of a wider defensive strategy. Rather than responding reactively, active cyber protection is the prevention, detection, monitoring, analysis and mitigation of network security breaches in an active manner, combined with the use of capabilities deployed within and outside the victim network. This could include Member States offering free services or tools to certain entities, including self-service checks, detection tools and takedown services. The ability to rapidly and automatically share and understand threat information and analysis, cyber activity alerts, and response action is critical to enable a unity of effort in successfully preventing, detecting, addressing and blocking attacks against network and information systems. Active cyber protection is based on a defensive strategy that excludes offensive measures.

In view of the differences in national governance structures and in order to safeguard already existing sectoral arrangements or Union supervisory and regulatory bodies, Member States should be able to designate or establish one or more competent authorities responsible for cybersecurity and for the supervisory tasks under this Directive.

In order to facilitate cross-border cooperation and communication among authorities and to enable this Directive to be implemented effectively, it is necessary for each Member State to designate a single point of contact responsible for coordinating issues related to the security of network and information systems and cross-border cooperation at Union level.

The single points of contact should ensure effective cross-border cooperation with relevant authorities of other Member States and, where appropriate, with the Commission and ENISA. The single points of contact should therefore be tasked with forwarding notifications of significant incidents with cross-border impact to the single points of contact of other affected Member States upon the request of the CSIRT or the competent authority. At national level, the single points of contact should enable smooth cross-sectoral cooperation with other competent authorities. The single points of contact could also be the addressees of relevant information about incidents concerning financial entities from the competent authorities under Regulation (EU) 2022/2554 which they should be able to forward, as appropriate, to the CSIRTs or the competent authorities under this Directive.

In accordance with the Annex to Recommendation (EU) 2017/1584, a large-scale cybersecurity incident should mean an incident which causes a level of disruption that exceeds a Member State’s capacity to respond to it or which has a significant impact on at least two Member States. Depending on their cause and impact, large-scale cybersecurity incidents may escalate and turn into fully-fledged crises not allowing the proper functioning of the internal market or posing serious public security and safety risks for entities or citizens in several Member States or the Union as a whole. Given the wide-ranging scope and, in most cases, the cross-border nature of such incidents, Member States and the relevant Union institutions, bodies, offices and agencies should cooperate at technical, operational and political level to properly coordinate the response across the Union.

Large-scale cybersecurity incidents and crises at Union level require coordinated action to ensure a rapid and effective response because of the high degree of interdependence between sectors and Member States. The availability of cyber-resilient network and information systems and the availability, confidentiality and integrity of data are vital for the security of the Union and for the protection of its citizens, businesses and institutions against incidents and cyber threats, as well as for enhancing the trust of individuals and organisations in the Union’s ability to promote and protect a global, open, free, stable and secure cyberspace grounded in human rights, fundamental freedoms, democracy and the rule of law.

Member States should be adequately equipped, in terms of both technical and organisational capabilities, to prevent, detect, respond to and mitigate incidents and risks. Member States should therefore establish or designate one or more CSIRTs under this Directive and ensure that they have adequate resources and technical capabilities. The CSIRTs should comply with the requirements laid down in this Directive in order to guarantee effective and compatible capabilities to deal with incidents and risks and to ensure efficient cooperation at Union level. Member States should be able to designate existing computer emergency response teams (CERTs) as CSIRTs. In order to enhance the trust relationship between the entities and the CSIRTs, where a CSIRT is part of a competent authority, Member States should be able to consider functional separation between the operational tasks provided by the CSIRTs, in particular in relation to information sharing and assistance provided to the entities, and the supervisory activities of the competent authorities.

As regards personal data, the CSIRTs should be able to provide, in accordance with Regulation (EU) 2016/679, upon the request of an essential or important entity, a proactive scanning of the network and information systems used for the provision of the entity’s services. Where applicable, Member States should aim to ensure an equal level of technical capabilities for all sectoral CSIRTs. Member States should be able to request the assistance of ENISA in developing their CSIRTs.

Given the importance of international cooperation on cybersecurity, the CSIRTs should be able to participate in international cooperation networks in addition to the CSIRTs network established by this Directive. Therefore, for the purpose of carrying out their tasks, the CSIRTs and the competent authorities should be able to exchange information, including personal data, with the national computer security incident response teams or competent authorities of third countries provided that the conditions under Union data protection law for transfers of personal data to third countries, inter alia those of Article 49 of Regulation (EU) 2016/679, are met.

The CSIRTs network should continue to contribute to strengthening confidence and trust and to promote swift and effective operational cooperation among Member States. In order to enhance operational cooperation at Union level, the CSIRTs network should consider inviting Union bodies and agencies involved in cybersecurity policy, such as Europol, to participate in its work.

In order to facilitate the effective implementation of this Directive with regard, inter alia, to the management of vulnerabilities, cybersecurity risk-management measures, reporting obligations and cybersecurity information-sharing arrangements, Member States can cooperate with third countries and undertake activities that are considered to be appropriate for that purpose, including information exchange on cyber threats, incidents, vulnerabilities, tools and methods, tactics, techniques and procedures, cybersecurity crisis management preparedness and exercises, training, trust building and structured information-sharing arrangements.

The CSIRTs are tasked with incident handling. This includes the processing of large volumes of sometimes sensitive data. Member States should ensure that the CSIRTs have an infrastructure for information sharing and processing, as well as well-equipped staff, which ensures the confidentiality and trustworthiness of their operations. The CSIRTs could also adopt codes of conduct in that respect.

The CSIRTs should have the ability, upon an essential or important entity’s request, to monitor the entity’s internet-facing assets, both on and off premises, in order to identify, understand and manage the entity’s overall organisational risks as regards newly identified supply chain compromises or critical vulnerabilities. The entity should be encouraged to communicate to the CSIRT whether it runs a privileged management interface, as this could affect the speed of undertaking mitigating actions.

Ensuring adequate resources to meet the objectives of this Directive and to enable the competent authorities and the CSIRTs to carry out the tasks laid down herein is essential. The Member States can introduce at the national level a financing mechanism to cover necessary expenditure in relation to the conduct of tasks of public entities responsible for cybersecurity in the Member State pursuant to this Directive. Such mechanism should comply with Union law and should be proportionate and non-discriminatory and should take into account different approaches to providing secure services.

The growing interdependencies are the result of an increasingly cross-border and interdependent network of service provision using key infrastructures across the Union in sectors such as energy, transport, digital infrastructure, drinking water and waste water, health, certain aspects of public administration, as well as space in so far as the provision of certain services depending on ground-based infrastructures that are owned, managed and operated either by Member States or by private parties is concerned, therefore not covering infrastructures owned, managed or operated by or on behalf of the Union as part of its space programme. Those interdependencies mean that any disruption, even one initially confined to one entity or one sector, can have cascading effects more broadly, potentially resulting in far-reaching and long-lasting negative impacts in the delivery of services across the internal market. The intensified cyberattacks during the COVID-19 pandemic have shown the vulnerability of increasingly interdependent societies in the face of low-probability risks.

Since the exploitation of vulnerabilities in network and information systems may cause significant disruption and harm, swiftly identifying and remedying such vulnerabilities is an important factor in reducing risk. Entities that develop or administer network and information systems should therefore establish appropriate procedures to handle vulnerabilities when they are discovered. Since vulnerabilities are often discovered and disclosed by third parties, the manufacturer or provider of ICT products or ICT services should also put in place the necessary procedures to receive vulnerability information from third parties. In that regard, international standards ISO/IEC 30111 and ISO/IEC 29147 provide guidance on vulnerability handling and vulnerability disclosure. Strengthening the coordination between reporting natural and legal persons and manufacturers or providers of ICT products or ICT services is particularly important for the purpose of facilitating the voluntary framework of vulnerability disclosure. Coordinated vulnerability disclosure specifies a structured process through which vulnerabilities are reported to the manufacturer or provider of the potentially vulnerable ICT products or ICT services in a manner allowing it to diagnose and remedy the vulnerability before detailed vulnerability information is disclosed to third parties or to the public. Coordinated vulnerability disclosure should also include coordination between the reporting natural or legal person and the manufacturer or provider of the potentially vulnerable ICT products or ICT services as regards the timing of remediation and publication of vulnerabilities.

The Commission, ENISA and the Member States should continue to foster alignments with international standards and existing industry best practices in the area of cybersecurity risk management, for example in the areas of supply chain security assessments, information sharing and vulnerability disclosure.

Member States should designate one of its CSIRTs as a coordinator, acting as a trusted intermediary between the reporting natural or legal persons and the manufacturers or providers of ICT products or ICT services, which are likely to be affected by the vulnerability, where necessary. The tasks of the CSIRT designated as coordinator should include identifying and contacting the entities concerned, assisting the natural or legal persons reporting a vulnerability, negotiating disclosure timelines and managing vulnerabilities that affect multiple entities (multi-party coordinated vulnerability disclosure). Where the reported vulnerability could have significant impact on entities in more than one Member State, the CSIRTs designated as coordinators should cooperate within the CSIRTs network, where appropriate.

Access to correct and timely information about vulnerabilities affecting ICT products and ICT services contributes to an enhanced cybersecurity risk management. Sources of publicly available information about vulnerabilities are an important tool for the entities and for the users of their services, but also for the competent authorities and the CSIRTs. For that reason, ENISA should establish a European vulnerability database where entities, regardless of whether they fall within the scope of this Directive, and their suppliers of network and information systems, as well as the competent authorities and the CSIRTs, can disclose and register, on a voluntary basis, publicly known vulnerabilities for the purpose of allowing users to take appropriate mitigating measures. The aim of that database is to address the unique challenges posed by risks to Union entities. Furthermore, ENISA should establish an appropriate procedure regarding the publication process in order to give entities the time to take mitigating measures as regards their vulnerabilities and employ state-of-the-art cybersecurity risk-management measures as well as machine-readable datasets and corresponding interfaces. To encourage a culture of disclosure of vulnerabilities, disclosure should have no detrimental effects on the reporting natural or legal person.

Although similar vulnerability registries or databases exist, they are hosted and maintained by entities which are not established in the Union. A European vulnerability database maintained by ENISA would provide improved transparency regarding the publication process before the vulnerability is publicly disclosed, and resilience in the event of a disruption or an interruption of the provision of similar services. In order, to the extent possible, to avoid a duplication of efforts and to seek complementarity, ENISA should explore the possibility of entering into structured cooperation agreements with similar registries or databases that fall under third-country jurisdiction. In particular, ENISA should explore the possibility of close cooperation with the operators of the Common Vulnerabilities and Exposures (CVE) system.

In order to avoid gaps between or duplications of cybersecurity obligations imposed on entities in the aviation sector, national authorities under Regulations (EC) No 300/2008 ⁽¹⁾ and (EU) 2018/1139 ⁽²⁾ of the European Parliament and of the Council and the competent authorities under this Directive should cooperate in relation to the implementation of cybersecurity risk-management measures and the supervision of compliance with those measures at national level. The compliance of an entity with the security requirements laid down in Regulations (EC) No 300/2008 and (EU) 2018/1139 and in the relevant delegated and implementing acts adopted pursuant to those Regulations could be considered by the competent authorities under this Directive to constitute compliance with the corresponding requirements laid down in this Directive.

(2) Regulation (EU) 2018/1139 of the European Parliament and of the Council of 4 July 2018 on common rules in the field of civil aviation and establishing a European Union Aviation Safety Agency, and amending Regulations (EC) No 2111/2005, (EC) No 1008/2008, (EU) No 996/2010, (EU) No 376/2014 and Directives 2014/30/EU and 2014/53/EU of the European Parliament and of the Council, and repealing Regulations (EC) No 552/2004 and (EC) No 216/2008 of the European Parliament and of the Council and Council Regulation (EEC) No 3922/91 (OJ L 212, 22.8.2018, p. 1).}

In view of the interlinkages between cybersecurity and the physical security of entities, a coherent approach should be ensured between Directive (EU) 2022/2557 of the European Parliament and of the Council ⁽¹⁾ and this Directive. To achieve this, entities identified as critical entities under Directive (EU) 2022/2557 should be considered to be essential entities under this Directive. Moreover, each Member State should ensure that its national cybersecurity strategy provides for a policy framework for enhanced coordination within that Member State between its competent authorities under this Directive and those under Directive (EU) 2022/2557 in the context of information sharing about risks, cyber threats, and incidents as well as on non-cyber risks, threats and incidents, and the exercise of supervisory tasks. The competent authorities under this Directive and those under Directive (EU) 2022/2557 should cooperate and exchange information without undue delay, in particular in relation to the identification of critical entities, risks, cyber threats, and incidents as well as in relation to non-cyber risks, threats and incidents affecting critical entities, including the cybersecurity and physical measures taken by critical entities as well as the results of supervisory activities carried out with regard to such entities.

Furthermore, in order to streamline supervisory activities between the competent authorities under this Directive and those under Directive (EU) 2022/2557 and in order to minimise the administrative burden for the entities concerned, those competent authorities should endeavour to harmonise incident notification templates and supervisory processes. Where appropriate, the competent authorities under Directive (EU) 2022/2557, should be able to request the competent authorities under this Directive to exercise their supervisory and enforcement powers in relation to an entity that is identified as a critical entity under Directive (EU) 2022/2557. The competent authorities under this Directive and those under Directive (EU) 2022/2557 should, where possible in real time, cooperate and exchange information for that purpose.
