The European Network and Information Security (NIS) Directive designates authoritative Domain Name System (DNS) services as essential services within the digital infrastructure sector. It is up to the EU member states to implement the directive and identify specific providers. In the Netherlands, the NIS Directive has been implemented in the Network and Information Systems Security Act (Wbni). Under the Wbni, operators of a top-level domain (from one million domain names) are designated as providers of an essential DNS service. However, there are other types of DNS service providers. The Ministry of Economic Affairs and Climate has commissioned Dialogic to conduct an inventory focusing on providers of authoritative DNS services.
In the research, the following questions will be answered:
- Which types of DNS services can be distinguished from a technical perspective?
- What are the possible consequences of disruption (also outside the sector) of these services?
- Which (types of) providers and users are involved?
- Who are the main providers based in the Netherlands.
On 5 July, State Secretary Keizer (EZK) presented this inventory to the House of Representatives.
