Network Information Systems Directive (NISD)

What is NISD?

The Network Information Systems Directive (NISD), is relevant to you if you are an Essential Service Provider or if you are a Digital Service Provider i.e. an online marketplace, an online search engine or a cloud services provider (unless you are subject to sector specific regulation in this area). The Directive may also be relevant to you if you are part of the supply chain of such providers.

Who has to comply with NISD?

The primary concern for those who think they might be caught by NISD centres on the definitions of an Operator of Essential Services (OES), and Digital Service Providers (DSPs).

  • OESs – the government has been refining the identification thresholds used to define who is in scope to make them clearer and help companies understand whether they need to comply.
  • DSPs – the government recognises that defining DSPs "continues to be a challenge" but intends to limit the scope of those who have to comply with NISD to "those companies whose loss of service could have the greatest impact on the UK economy, either directly or through impact on other companies". This will include Software as a Service companies but excludes micro and small businesses.

In short, if you are in the critical sectors of financial services, health, water, energy, transport and Telecommunications you will be required to assess your risks and ensure they have the appropriate controls in place. E-commerce platforms are also considered part of the critical infrastructure.

Assessment Framework

The National Cyber Security Centre (NCSC) has published the NISD Cyber Assessment Framework (CAF). It is mandatory for the OES to be assessed against the CAF.

There has been a lot of concern around the potential for 'double jeopardy' in terms of fines under NISD and the GDPR. The government confirms that it intends to amend the proposed penalty regime to introduce a maximum financial penalty of £17m for all contraventions under NISD. It cannot, however, remove the possibility of additional sanctions relating to different aspects of wrongdoing under other applicable law, including the GDPR.
Note that NISD will not apply directly to suppliers to OES's or DSPs and enforcement will not take place down the supply chain. OESs and DSPs will be responsible for ensuring that their suppliers have appropriate measures in place to ensure they are compliant.

Incident reporting, Enforcement and Guidance

There are currently 11 Competent Authorities (CAs) that are responsible for reporting, enforcement and assistance around the implementation of the NISD. They are a mix of the existing sector regulators and/or the responsible Government Departments.

The government clarifies that CAs will publish incident reporting thresholds. Reporting timeframes will mirror those under the GDPR, i.e. "without undue delay and, where feasible, no later than 72 hours after having become aware of the incident".

Incident reporting under NISD focuses on interruption to service. Under Article 14(3), an OES must notify either their CA or Computer Security Incident Response Team (CSIRT) of "incidents having a significant impact on the continuity of the essential services they provide". DSPs are required under Article 16(3) to notify either their CA or Computer Security Incident Response Team (CSIRT) of "any incident having a substantial impact on the provision of a service…that they offer within the Union". An incident is "any event having an actual adverse effect on the security of network and information systems"
