Article 21 Cybersecurity risk-management measures

Cybersecurity risk-management measures should take into account the degree of dependence of the essential or important entity on network and information systems and include measures to identify any risks of incidents, to prevent, detect, respond to and recover from incidents and to mitigate their impact. The security of network and information systems should include the security of stored, transmitted and processed data. Cybersecurity risk-management measures should provide for systemic analysis, taking into account the human factor, in order to have a complete picture of the security of the network and information system.

As threats to the security of network and information systems can have different origins, cybersecurity risk-management measures should be based on an all-hazards approach, which aims to protect network and information systems and the physical environment of those systems from events such as theft, fire, flood, telecommunication or power failures, or unauthorised physical access and damage to, and interference with, an essential or important entity’s information and information processing facilities, which could compromise the availability, authenticity, integrity or confidentiality of stored, transmitted or processed data or of the services offered by, or accessible via, network and information systems. The cybersecurity risk-management measures should therefore also address the physical and environmental security of network and information systems by including measures to protect such systems from system failures, human error, malicious acts or natural phenomena, in line with European and international standards, such as those included in the ISO/IEC 27000 series. In that regard, essential and important entities should, as part of their cybersecurity risk-management measures, also address human resources security and have in place appropriate access control policies. Those measures should be consistent with Directive (EU) 2022/2557.

In order to avoid imposing a disproportionate financial and administrative burden on essential and important entities, the cybersecurity risk-management measures should be proportionate to the risks posed to the network and information system concerned, taking into account the state-of-the-art of such measures, and, where applicable, relevant European and international standards, as well as the cost for their implementation.

Cybersecurity risk-management measures should be proportionate to the degree of the essential or important entity’s exposure to risks and to the societal and economic impact that an incident would have. When establishing cybersecurity risk-management measures adapted to essential and important entities, due account should be taken of the divergent risk exposure of essential and important entities, such as the criticality of the entity, the risks, including societal risks, to which it is exposed, the entity’s size and the likelihood of occurrence of incidents and their severity, including their societal and economic impact.

Essential and important entities should ensure the security of the network and information systems which they use in their activities. Those systems are primarily private network and information systems managed by the essential and important entities’ internal IT staff or the security of which has been outsourced. The cybersecurity risk-management measures and reporting obligations laid down in this Directive should apply to the relevant essential and important entities regardless of whether those entities maintain their network and information systems internally or outsource the maintenance thereof.

Taking account of their cross-border nature, DNS service providers, TLD name registries, cloud computing service providers, data centre service providers, content delivery network providers, managed service providers, managed security service providers, providers of online marketplaces, of online search engines and of social networking services platforms, and trust service providers should be subject to a high degree of harmonisation at Union level. The implementation of cybersecurity risk-management measures with regard to those entities should therefore be facilitated by an implementing act.

Addressing risks stemming from an entity’s supply chain and its relationship with its suppliers, such as providers of data storage and processing services or managed security service providers and software editors, is particularly important given the prevalence of incidents where entities have been the victim of cyberattacks and where malicious perpetrators were able to compromise the security of an entity’s network and information systems by exploiting vulnerabilities affecting third-party products and services. Essential and important entities should therefore assess and take into account the overall quality and resilience of products and services, the cybersecurity risk-management measures embedded in them, and the cybersecurity practices of their suppliers and service providers, including their secure development procedures. Essential and important entities should in particular be encouraged to incorporate cybersecurity risk-management measures into contractual arrangements with their direct suppliers and service providers. Those entities could consider risks stemming from other levels of suppliers and service providers.

Among service providers, managed security service providers in areas such as incident response, penetration testing, security audits and consultancy play a particularly important role in assisting entities in their efforts to prevent, detect, respond to or recover from incidents. Managed security service providers have however also themselves been the target of cyberattacks and, because of their close integration in the operations of entities pose a particular risk. Essential and important entities should therefore exercise increased diligence in selecting a managed security service provider.

Essential and important entities should also address risks stemming from their interactions and relationships with other stakeholders within a broader ecosystem, including with regard to countering industrial espionage and protecting trade secrets. In particular, those entities should take appropriate measures to ensure that their cooperation with academic and research institutions takes place in line with their cybersecurity policies and follows good practices as regards secure access and dissemination of information in general and the protection of intellectual property in particular. Similarly, given the importance and value of data for the activities of essential and important entities, when relying on data transformation and data analytics services from third parties, those entities should take all appropriate cybersecurity risk-management measures.

Essential and important entities should adopt a wide range of basic cyber hygiene practices, such as zero-trust principles, software updates, device configuration, network segmentation, identity and access management or user awareness, organise training for their staff and raise awareness concerning cyber threats, phishing or social engineering techniques. Furthermore, those entities should evaluate their own cybersecurity capabilities and, where appropriate, pursue the integration of cybersecurity enhancing technologies, such as artificial intelligence or machine-learning systems to enhance their capabilities and the security of network and information systems.

This Directive should aim to ensure a high level of responsibility for the cybersecurity risk-management measures and reporting obligations at the level of the essential and important entities. Therefore, the management bodies of the essential and important entities should approve the cybersecurity risk-management measures and oversee their implementation.

In order to ensure uniform conditions for the implementation of this Directive, implementing powers should be conferred on the Commission to lay down the procedural arrangements necessary for the functioning of the Cooperation Group and the technical and methodological as well as sectoral requirements concerning the cybersecurity risk-management measures, and to further specify the type of information, the format and the procedure of incident, cyber threat and near miss notifications and of significant cyber threat communications, as well as cases in which an incident is to be considered to be significant. Those powers should be exercised in accordance with Regulation (EU) No 182/2011 of the European Parliament and of the Council(²³)Regulation (EU) No 182/2011 of the European Parliament and of the Council of 16 February 2011 laying down the rules and general principles concerning mechanisms for control by the Member States of the Commission’s exercise of implementing powers (OJ L 55, 28.2.2011, p. 13)..
