[Full disclaimer: Written with ChatGPT. Still interesting âïž]. NIS2 (Network and Information Security Directive 2), which is a revised version of the NIS directive, is designed to strengthen the security of networks and information systems in the EU. It came into force to meet new security challenges in an increasingly digitized world and has a broader scope compared to the previous directive. Regarding websites and sites hosted in Sweden, here is an overview of what is affected:
Key sectors: NIS2 covers organizations providing services within specific critical sectors. This includes energy, transport, banking, financial market infrastructure, healthcare, drinking water, sewage systems, digital infrastructure, public administration, and other similar critical societal activities. Websites belonging to these sectors are directly covered by NIS2.
Digital service providers: Companies offering digital services, including web services like hosting, cloud services, and search engines, are affected by NIS2. This means that if you have your site hosted by a service provider covered by the directive, there may be requirements for these providers to meet certain security measures.
Medium and large companies: A major change with NIS2 is that more companies are covered, including larger and medium-sized companies within the affected sectors, unlike before, where the focus was primarily on larger actors. This means that websites for companies operating in sectors covered by the directive may need to follow the requirements even if they are not of the same size as previously regulated actors.
Services used for society's vital functions: If a website or online platform is critical for maintaining important societal functions, such as a news site with high reach, a public portal, or a service for communication and emergencies, it is covered by the directive.
Hosting companies and cloud service providers: If the site is hosted by a Swedish hosting company that is also covered by NIS2 requirements (because it provides important digital infrastructure or cloud services), there are security requirements that the company must meet, which in turn affects the security standards for customers' websites.
Requirements and measures under NIS2:
To comply with NIS2, websites and their operators must implement a number of security measures, such as:
- Risk management and security policy: Applicable security measures based on risk assessment.
- Incident reporting: Rapid reporting of security incidents, usually within 24 hours of discovery.
- Resilience and continuity: Maintaining operations even during security incidents.
- Security audits: Regular security audits and evaluations.
In practice, this means that if you have a website hosted in Sweden and it falls under one of the aforementioned categories, or if your hosting provider is an actor covered by NIS2, you must ensure that relevant security measures are in place.
In summary, primarily websites within critical sectors or those providing vital societal services are affected, but also companies offering digital services such as hosting and cloud services are covered by the requirements in NIS2.
