This transition to NIS2 compliance carries substantial implications for most entities falling under NIS2's scope, often necessitating a transitional period of 1-3 years. Therefore, it is imperative to initiate the requisite measures well in advance. To facilitate this, we have developed an (initial) assessment tool, aligning NIS2 requirements with ISO 27001 standards. While the precise details of NIS2 requirements remain undisclosed, the ISO 27001 framework serves as a sound baseline for evaluating an organization's cybersecurity posture. The tool is designed to gauge an organization's compliance with pertinent controls, thereby aiding in proactive readiness for the impending Member State adaptations.
The table below maps the NIS2 measures to the ISO/IEC 27001:2022 standard. ISO 27001 is intended to give a framework of best practice policies, procedures and controls for information security, to reduce the risk for information security breaches. In mapping NIS2 measures to the ISO 27001:2022 standard, mainly the relevant controls from Annex A of the ISO 27001:2022 standard are referenced as they provide the best clues from a control perspective.
A mapping of the NIS2 measures to ISO 27002:2022 will be presented as well, but separately at a later stage, as both standards have their distinctive place and are relevant to look at from a NIS2 perspective. ISO 27001 is designed to build the foundations of information security and the framework. ISO 27002 is about implementation controls and guidelines. ISO 27001 is not as detailed when compared to ISO 27002 about implementation controls and guidelines. Although ISO 27002 provides the details needed to implement Annex A controls defined in ISO 27001, mapping NIS2 to ISO 27001 directly has its place as well, given the role that ISO 27001 plays in laying the foundations for information security. The table below provides the details of the mapping of NIS2 to the ISO 27001:2022 standard.
