Under the NIS directive, who must a CSP notify of an incident affecting the continuity of essential services?

The correct response highlights the necessity for a cloud service provider (CSP) to notify competent authorities in the event of an incident that impacts the continuity of essential services, as mandated by the NIS Directive. Under this directive, which aims to enhance cybersecurity across the European Union, CSPs are classified as essential or important entities. Consequently, when such an incident occurs, they are required to report it to designated competent authorities to ensure the prompt enactment of appropriate measures and mitigate potential impacts on service delivery.

This notification requirement serves multiple purposes: it allows the authorities to assess the situation, coordinate responses, and provide guidance or resources that may be needed to address the incident. It also plays a vital role in maintaining overall security and resilience within critical infrastructure sectors.

In contrast, the other options relate to different regulatory bodies or stakeholders that may have roles regarding data protection or oversight but are not specifically designated under the NIS directive for incident reporting related to service continuity. Data protection regulators, for example, typically focus on compliance with privacy laws, while commissions or supplier providers may have other roles that do not directly pertain to the requirements set forth in the NIS directive regarding incident notification.
