Executive summary: NIS2 Directive for the EU members (updated)

/in

The NIS 2 Directive is a set of cybersecurity guidelines and requirements established by the European Union (EU) . It replaces and repeals the NIS Directive (Directive 2016/1148/EC) . The full name of the directive is “Directive (EU) 2022/2555 of the European Parliament and of the Council of 14 December 2022 on measures for a high common level of cybersecurity across the Union, amending Regulation (EU) No 910/2014 and Directive (EU) 2018/1972, and repealing Directive (EU) 2016/1148 (NIS 2 Directive)” .

The NIS 2 Directive aims to improve cybersecurity risk management and introduce reporting obligations across sectors such as energy, transport, health, and digital infrastructure . It provides legal measures to boost the overall level of cybersecurity in the EU .

The directive covers a larger share of the economy and society by including more sectors, which means that more entities are obliged to take measures to increase their level of cybersecurity .

The management bodies of essential and important entities must approve the cybersecurity risk-management measures taken by those entities, oversee its implementation, and can be held liable for infringements .

 

Who is affected?

The NIS 2 Directive significantly expands the sectors and type of critical entities falling under its scope.

As a ground rule, companies from certain areas that meet these conditions are affected:

Essential Entities (EE):

  • at least 250 employees and
  • 50 Mil € revenue

Important Entities (IE):

  • at least 50 employees and
  • 10 Mil € revenue

 

NIS 2 covers areas such as

  • Essential Entities:
    • energy (electricity, district heating and cooling, oil, gas and hydrogen);
    • transport (air, rail, water and road); banking;
    • financial market infrastructures;
    • health including  manufacture of pharmaceutical products including vaccines;
    • drinking water;
    • waste water;
    • digital infrastructure (internet exchange points; DNS service providers;
    • TLD name registries; cloud computing service providers;
    • data centre service providers;
    • content delivery networks;
    • trust service providers;
    • providers of  public electronic communications networks and publicly available electronic communications services);
    • ICT service management (managed service providers and managed security service providers), public administration and space.

Important Entities:

    • postal and courier services;
    • waste management;
    • chemicals;
    • food;
    • manufacturing of medical devices, computers and electronics, machinery and equipment, motor vehicles, trailers and semi-trailers and other transport equipment;
    • digital providers (online market places, online search engines, and social networking service platforms) and research organisations.

Note:
An entity may still be considered “essential” or “important” even if it does not meet the size criteria, in specific cases such as when it is the sole provider of a critical service for societal or economic activity in a Member State.

 

Deadlines

The Member States have until October 17, 2024, to adopt and publish the measures necessary to comply with the NIS 2 Directive. They shall apply those measures from October 18, 2024 .

The benefits of the NIS 2 directive include creating the necessary cyber crisis management structure (CyCLONe), increasing the level of harmonization regarding security requirements and reporting obligations, encouraging Members States to introduce new areas of interest such as supply chain, vulnerability management, core internet, and cyber hygiene in their national cybersecurity strategies, bringing novel ideas such as peer reviews for enhancing collaboration and knowledge sharing amongst Member States .

In order to comply with the NIS 2 directive, entities will need to take measures to increase their level of cybersecurity. This may include following training for members of management bodies of essential and important entities as well as offering similar training to their employees on a regular basis .

How does the NIS 2 Directive differ from the previous directive?

The NIS 2 Directive replaces the previous Network and Information Security (NIS) Directive, which was the first piece of EU-wide legislation on cybersecurity. Its specific aim was to achieve a high common level of cybersecurity across the Member States .

While the NIS Directive increased the Member States’ cybersecurity capabilities, its implementation proved difficult, resulting in fragmentation at different levels across the internal market. To respond to the growing threats posed by digitalization and the surge in cyber-attacks, the Commission submitted a proposal to replace the NIS Directive and thereby strengthen security requirements, address security of supply chains, streamline reporting obligations, and introduce more stringent supervisory measures and stricter enforcement requirements, including harmonized sanctions across the EU .

 

Consequences

The proposed expansion of the scope covered by NIS 2, by effectively obliging more entities and sectors to take measures, would assist in increasing the level of cybersecurity in Europe in the longer term . The NIS 2 Directive establishes very strict sanctions for breaches of its obligations. In contrast to the previous NIS Directive, which merely required Member States to set forth effective, proportionate and dissuasive penalties for non-compliance, the NIS 2 Directive introduces a much stricter regime .

NIS 2 will introduce a fining regime for non-compliance. The potential maximum fines for non-compliance could reach either

(i) €10 million or 2% of global annual turnover for “essential” entities or

(ii) €7 million or 1.4% of global annual turnover for “important” entities .

What’s next, if you are in a hurry

Try to identify the following topics in your ISMS and map them to the NIS2 requirements.

1. Scope of Application

  • Expansion of Affected Entities: NIS2 extends its requirements beyond the sectors covered by the original NIS Directive, including essential and important entities across various sectors such as energy, transport, health, and digital services.

2. Risk Management Measures

  • Comprehensive Security Requirements: Entities are required to implement appropriate technical and organizational measures to manage the risks posed to the security of network and information systems, including measures for incident handling, business continuity, and supply chain security.

3. Incident Response and Reporting

  • Incident Reporting Obligations: NIS2 mandates strict incident reporting requirements, where entities must notify relevant national authorities about significant cybersecurity incidents with potentially severe operational impacts, within a short timeframe.

4. Supply Chain Security

  • Security of Supply Chains and Supplier Relationships: Entities need to address cybersecurity risks not only within their own operations but also across their supply chains, ensuring that suppliers meet security requirements to protect against potential vulnerabilities and threats.

5. Interoperability and Cooperation

  • Enhanced Cooperation Among States: NIS2 emphasizes improved information sharing and coordinated response among EU member states, with mechanisms for cross-border collaboration in cybersecurity threat detection, response, and recovery.

6. Security and Network Systems

  • Strengthening of Security Practices: Detailed requirements on securing network and information systems, ensuring the integrity, availability, and confidentiality of services, particularly in critical infrastructure sectors.

7. Regulatory Oversight and Compliance

  • Increased Enforcement Powers: Regulatory authorities are granted more significant powers to enforce the Directive, including the ability to conduct audits, review compliance, and impose sanctions on entities failing to meet the cybersecurity requirements.

8. Financial Penalties

  • Penalties for Non-Compliance: NIS2 introduces substantial financial penalties for non-compliance, aimed at ensuring that entities take their cybersecurity obligations seriously.

9. Cybersecurity Measures Specificity

  • Detailed Guidelines and Standards: The Directive encourages the use of established standards and specifications to fulfill the required security measures, promoting best practices in cybersecurity management.

 

By addressing these key topics, NIS2 aims to significantly raise the level of cybersecurity across the EU, ensuring a uniform level of security in critical sectors and enhancing the resilience of the internal market against cyber threats.

NIS-2: 10 common misconceptions about the regulation

/in

We wrote here about NIS2 and we will continue to add more content about it.

Because we are getting closer to October 17th, many people are getting more and more nervous about NIS2.

Despite its significance, there are numerous misconceptions and misinterpretations circulating about the scope and implications of this regulation.

This article aims to clarify some of the misconceptions,  which I collected mostly from LinkedIn and articles about NIS-2.

 

Note:

“NIS2” and “NIS-2” are exactly the same thing. I am using both in this article only because of SEO.

 

 

1. NIS2 starts being applied in the EU starting 17.10.2024

Truth is that the regulation is already applicable in the EU since it was approved. This deadline applies to the individual countries of the EU to convert and apply the NIS2 requirements in local laws.

If national authorities fail to properly implement EU laws, the Commission may launch a formal infringement procedure against the country in question. If the issue is still not settled, the Commission may eventually refer the case to the Court of Justice of the European Union.

 

2. Limited scope of application

Contrary to the belief that NIS-2 only applies to large tech companies, the directive significantly broadens its scope compared to its predecessor, NIS.

NIS-2 extends beyond just critical infrastructure sectors like energy and transport, encompassing a wide array of sectors such as digital services, public administration, and healthcare.

It mandates a security and incident reporting framework that applies to both Essential and Important Entities, significantly expanding the list of sectors and services affected.

3. NIS-2 Is Just About Cybersecurity

While cybersecurity is a core component, NIS-2 is not merely about preventing cyberattacks. The directive emphasizes a comprehensive approach to security, which includes resilience against a wide range of threats.

This includes but it is not limited to:

  • supply chain security,
  • incident response, and
  • crisis management.

It establishes a baseline for security measures and incident notifications that entities must adhere to, ensuring a uniform level of security across member states.

4. NIS-2 compliance is the same across all EU countries

Although NIS-2 sets a framework for cybersecurity across the EU, member states have some flexibility in implementation. This means that there can be variations in how directives are enforced from one country to another, depending on local laws and regulations.

Companies operating across multiple jurisdictions need to be aware of and comply with local variations to ensure full compliance.

5. Heavy penalties are the main compliance driver

While it is true that NIS-2 can impose hefty fines for non-compliance, focusing solely on penalties misses the broader objective of the directive.

NIS-2 is designed to cultivate a culture of security and resilience. It encourages entities to proactively manage their cybersecurity risks and to collaborate with national authorities.

This cooperative approach is fundamental to enhancing the overall cybersecurity posture of the EU.

6. NIS-2 does not affect third-party suppliers

NIS-2 places explicit requirements on the security practices of third-party suppliers. Entities covered under the directive are required to ensure that their supply chains are secure.

This includes mandatory risk assessments and incident reporting requirements that extend to service providers, reflecting an understanding that security is only as strong as the weakest link in the supply chain.

 

7. NIS-2 contains rules for AI, IoT, Industry 4.0.

NIS-2 sets a framework for cybersecurity and it does not address anything in particular. However, the rules described can be very well applied to companies in the fields like those mentioned that fall under the regulation applicability.

The companies active in Digital Infrastructure Services (Internet Nodes, DNS Service Providers, TLD Registries, Cloud Providers, Data Centers, Content Delivery Networks, Trust Services, Communication Networks, Communication Services ) and in

ICT Service Management (B2B only) (Managed Services (IT, Networks/Infrastructure, Applications), Managed Security Services (Risk and Cyber Security) ) are potentially directly affected by the regulation. However, there are clear criteria about which companies are affected.

 

8. Any company with activity in the domains marked as Important and Essential is affected by NIS-2

Although the domains are under the NIS-2 regulation, a company is affected if it meets the criteria:

  • Essential Entities (EE):
    • at least 250 employees and
    • 50 Mil € revenue
  • Important Entities (IE):
    • at least 50 employees and
    • 10 Mil € revenue

If a company doesn’t have these characteristics, then, in general, it is not affected by the regulation directly. It is highly recommended that even in such cases the companies follow the regulation’s requirements, since it will increase their resilience against cyber attacks.

However, an entity may still be considered “essential” or “important” even if it does not meet the size criteria, in specific cases such as when it is the sole provider of a critical service for societal or economic activity in a Member State.

 

9. All affected companies must certify for NIS-2

A the time of writing this post there is no certification for NIS-2. This might change in the future, especially when because we don’t know at this time how the regulation will be implemented in each of the EU member states.

There are consulting companies that sell consulting services and guarantee that a company will get the “NIS-2  certification” if they bus their services. While buying consulting is in general a good thing, the only thing that can be obtained is help in meeting the requirements of the regulation.

I recommend to stay away from offers that promise things that don’t exist.

 

10. Companies can buy software/hardware products to become conform with NIS-2

Although conformity is sometimes made easier by using specialized software and hardware products, there is no requirement or recommendation to purchase anything.

Some security providers and consulting companies are offering On The Shelf  (OTS) products that promise immediate conformity with NIS-2 (or guarantee obtaining a “certification” – see point 9 above).

If you look at the series of articles in the NIS2 area of this website, you will see that actually quite a lot of  steps involve an ISMS, a cybersecurity framework, cybersecurity products and so on.

These can be implemented with commercial or open source products, but there is still need to know where and how to install them in order to become conform.

I can very well imagine that there will be soon commercial offerings with sets of templates for implementing the NIS-2 requirements, just like there are with ISO 27001, TISAX and other certifications.

Understanding ISO 27001:2022 Annex A.13 – Communications Security

/in

We started the ISO 27001:2022 series with the promise of explaining how the 14 categories of controls can be implemented.

Today we address ISO 27001:2022 Annex A.13, “Communications Security”, which addresses the importance of securing information during its transmission over communication networks.

This annex provides guidelines for implementing controls to protect the confidentiality, integrity, and availability of information exchanged between parties.

 

 

Importance of Communications Security

Communications security is crucial for safeguarding sensitive information transmitted over communication channels, such as networks, internet connections, and wireless technologies. Annex A.13 underscores this importance by:

  1. Confidentiality: Encrypting communications prevents unauthorized parties from intercepting and eavesdropping on sensitive information transmitted over unsecured networks.
  2. Integrity: Implementing integrity checks and digital signatures ensures that transmitted data remains intact and unaltered during transit, protecting against tampering and unauthorized modifications.
  3. Availability: Securing communication channels helps maintain the availability of information services and prevents disruptions caused by network attacks, denial-of-service (DoS) attacks, or transmission errors.

Implementing Annex A.13 in Practice

To effectively implement Annex A.13, organizations can follow these practical steps:

  1. Encryption: Encrypt data transmitted over insecure communication channels using encryption protocols such as Transport Layer Security (TLS), Secure Sockets Layer (SSL), or Virtual Private Network (VPN) tunnels.Example: Configure email servers to use TLS encryption for encrypting emails in transit between email clients and servers, preventing eavesdropping on email communications.
  2. Digital Signatures: Use digital signatures to verify the authenticity and integrity of transmitted data and messages. Implement digital signature algorithms and certificate authorities to ensure the validity of signatures.Example: Digitally sign electronic documents, such as contracts or reports, using a digital signature certificate issued by a trusted certificate authority to verify the authenticity and integrity of the documents.
  3. Secure Protocols: Use secure communication protocols and standards, such as Secure Shell (SSH), Hypertext Transfer Protocol Secure (HTTPS), and Internet Protocol Security (IPsec), to protect data transmitted over networks.Example: Configure web servers to use HTTPS protocol for secure transmission of sensitive information, such as login credentials or financial transactions, over the internet.
