The NIS2 Directive complements standards like ISO27001, ISACA CSX, IT RISK 27005, PCI-DSS, DORA, GDPR, and Decree Law 65/2021.
Non-compliance with NIS2 places the responsibility for risks and damages directly on the organization’s management (Governance).
Q2: What is NIS2?
NIS2 (Network and Information Security Directive 2) is the updated version of the EU’s directive focused on improving cybersecurity and resilience of networks and information systems across the European Union. First adopted in 2016, the original NIS Directive marked the EU’s first significant cybersecurity legislation. However, the growing threat of cyberattacks and the evolving digital landscape necessitated updates and expansions in its provisions.
NIS2 introduces the following enhancements:
- Broader Scope: NIS2 now applies to additional sectors and types of entities, including critical areas like food, healthcare, energy, transport, water, telecommunications, digital services, waste management, and public administration.
- Strengthened Security Requirements: The directive enforces stricter security measures for organizations.
- Enhanced Cooperation: NIS2 fosters greater cooperation and information exchange between EU Member States and relevant authorities.
- Increased Oversight and Enforcement: National authorities will have more power to enforce NIS2 compliance, including the ability to impose sanctions for non-compliance.
NIS2 thus aims to create a more secure and resilient digital environment in the European Union, better protecting citizens and businesses against cyber threats.
ISO 27001 is an international standard that specifies the requirements for an information security management system (ISMS). It provides a framework for managing information security and ensuring that security controls are effectively implemented. Its connection to NIS2 lies in the fact that ISO 27001 can serve as a foundation for operators to meet the security requirements mandated by the directive.
The Cybersecurity Nexus (CSX) by ISACA is a certification and guidance framework for cybersecurity. While it is not a standard or legislation like NIS2, CSX offers resources and certifications that can help organizations build their cybersecurity capabilities, aligning with the compliance goals of NIS2.
ISO 27005 is a standard that provides guidelines for information security risk management. It complements ISO 27001 by offering a structured approach to identifying, assessing, and addressing risks. Risk management is a key component of NIS2, making ISO 27005 relevant for organizations seeking compliance.
The Payment Card Industry Data Security Standard (PCI-DSS) is a set of security standards designed to protect payment card information. While PCI-DSS is specific to the payments industry, the security principles it promotes are applicable to many of the security requirements of NIS2.
The Digital Operational Resilience Act (DORA) is another EU regulation focused on the digital operational resilience of financial entities. While NIS2 covers a broader range of sectors, DORA is specific to the financial sector, but both share the goal of strengthening cybersecurity resilience.
The General Data Protection Regulation (GDPR) focuses on the protection of personal data. While GDPR and NIS2 have different focuses, both require organizations to implement appropriate security measures to protect data and systems, creating an overlap in terms of security requirements.
Decree-Law 65/2021 is Portuguese legislation that transposes the original NIS directive into national law. It establishes security requirements for operators of essential services and digital service providers in Portugal. Its relationship with NIS2 is direct, as DL 65/2021 is the national implementation of the NIS directive, and it is expected to be updated to reflect the changes introduced by NIS2.
In summary, NIS2 is related to these standards, regulations, and frameworks through the common goal of enhancing cybersecurity and operational resilience, though each has its specific focus and scope.
Q2. What is the significance and impact of NIS2 on organizations in Europe?
The Importance and Impact of NIS2 on Organizations
NIS2 aims to improve the security of networks and information systems, minimizing the risks of cyberattacks and other threats. In today’s digital age, critical infrastructures and essential services increasingly rely on technology, making cybersecurity vital. The directive seeks to harmonize cybersecurity requirements across the European Union, ensuring that all Member States adopt a minimum level of protection. This uniformity promotes cross-border cooperation and coordinated responses to cybersecurity incidents.
Expanded Scope of Sectors
NIS2 covers additional critical sectors such as wastewater management, space, public administration, research, food production, chemical industries, postal services, and IT management (B2B). These sectors join existing ones like healthcare, energy, water, transport, and digital infrastructure, ensuring that essential services for society and the economy are better protected.
Organizations covered by NIS2 will have to comply with stricter cybersecurity requirements, which may involve additional investments in security technologies, staff training, and risk management processes.
National authorities will have more powers to oversee and audit the cybersecurity practices of organizations. This may lead to increased scrutiny and the need for companies to document and demonstrate their compliance.
NIS2 provides for the possibility of significant sanctions for organizations that fail to meet the established requirements. This increases the accountability of companies and could have a significant financial impact in case of non-compliance. For essential entities, fines can reach up to a maximum of €10 million or 2% of the organization’s total global annual turnover. For important entities, fines can go up to a maximum of €7 million or at least 1.4% of the organization’s total global annual turnover.
Organizations will be encouraged to cooperate more closely with national authorities and other stakeholders by sharing information about cybersecurity threats and incidents. This can improve incident response but will also require adjustments to internal communication and incident management processes.
The implementation of the measures required by NIS2 can increase organizations’ resilience against cyberattacks, protecting not only the organization itself but also its customers and partners.
NIS2 allows for compliance in 10 essential areas:
- Risk analysis policies and security of information systems (critical data and systems; information assets; secure access);
- Incident management (response time; damage containment; communication and channels);
- Business continuity (BCP), such as backup management (3-2-1-1) and disaster recovery (DRP), and crisis management (Article 21, paragraph 2, point c);
- Supply chain security (employees, suppliers, partners, and customers);
- Security of the acquisition, development, and maintenance of networks and information systems;
- Assessment of the effectiveness of cybersecurity risk management measures (regular tests and audits);
- Training in cyber hygiene and cybersecurity;
- Policies and procedures regarding the use of cryptography and, if applicable, encryption;
- Security of human resources, access control policies, and asset management;
- Use of multi-factor authentication solutions.
NIS2 represents an important step in strengthening cybersecurity in Europe but also imposes new challenges and responsibilities on organizations. Compliance with the directive will require a continuous commitment to improving security practices and adapting to new regulatory requirements, which will demand greater investment but with superior benefits.
