D2.1 Cybersecurity landscape and threat analysis, end-user requirement analysis and use case definition - Initial version

This document provides an initial Cybersecurity Landscape and Threat Analysis, End-User Requirement Analysis, and Use Case Definition. It provides a concise examination of cybersecurity challenges affecting SMEs, detailing prevalent threats, impacts, and threats and analysing the literature review on the basis of NIST Cybersecurity Framework (CSF) 2.0. Additionally, the document encompasses an End-User Requirement Analysis conducted through the NERO questionnaire, the results of which are utilised to create an initial set of requirements tailored to the end-users' needs in combination with the insights from the literature review. Furthermore, D2.1 showcases the NERO Ecosystem through a high-level architecture, the functionality of each partner’s tool that will be used within the NERO Ecosystem, and the demonstration of the tools in different use cases. These initial technical specifications intend to serve as a common reference and driver for the development and implementation in all other technical tasks of the project, including WP3, WP4, WP5 and WP6.
