NIS 2 Directive Article 6 – Definitions

In the evolving landscape of cybersecurity and information systems, it is essential to clearly understand the key terms and definitions outlined in the NIS 2 Directive Article 6. These definitions provide a framework for effectively assessing and addressing cybersecurity threats and incidents. Let's delve into some of the crucial definitions:

• Network and Information System (NIS): These are defined as interconnected electronic communications networks and digital data processing devices. They play a vital role in our digital infrastructure and must be safeguarded against cyber threats.

• Security of NIS: This refers to the system's capacity to maintain data availability, authenticity, integrity, and confidentiality. Protecting NIS from vulnerabilities and cyber attacks is crucial in ensuring smooth operations and data protection.

• Cybersecurity and Cyber Threat: As per Regulation (EU) 2019/881, cybersecurity encompasses measures to protect information and communication technologies (ICT) systems from cyber threats. A cyber threat is any potential danger to the security of digital data and systems.

• National Cybersecurity Strategy: Each Member State is encouraged to develop a strategic framework for cybersecurity, outlining objectives and governance structures to enhance cybersecurity resilience at a national level.

• Incident Handling: This process involves the prevention, detection, analysis, containment, response, and recovery actions during a cybersecurity incident. Effective incident handling can minimize the impact of cyber threats on NIS.

• Risk: Assessing the potential for loss or disruption to NIS is essential in developing risk management strategies. Evaluating the likelihood and impact of cybersecurity incidents helps organizations prioritize security measures.

• ICT Products, Services, and Processes: These encompass various electronic and digital technologies, including software, hardware, and communication networks. Regulation (EU) 2019/881 provides guidelines for securing these ICT assets.

• Vulnerability: Refers to exploitable weaknesses in ICT products or services that can be targeted by cyber attackers. Identifying and mitigating vulnerabilities is crucial in strengthening the security of NIS.

• Standards and Technical Specifications: Compliance with industry standards and technical requirements, as outlined in Regulation (EU) No 1025/2012, is vital for ensuring the interoperability and security of ICT systems.

• Internet Exchange Point and Domain Name System (DNS): These facilities and systems are critical in managing Internet traffic and resolving domain names. DNS service providers and TLD registries are responsible for administering specific top-level domains.

Understanding these definitions is essential for organizations and policymakers to navigate the complex cybersecurity landscape and uphold the integrity and security of Network and Information Systems. By adhering to the principles outlined in NIS 2 Directive Article 6, stakeholders can effectively mitigate cyber threats and safeguard critical digital assets.
