For this reason, the European Directive NIS2 has emerged as a key tool in assisting organizations in protecting themselves against growing cyber-attacks. The challenge, however, lies in implementing the Directive effectively, which results in inconsistent approaches to compliance. This master’s thesis proposes using Enterprise Architecture (EA) and ArchiMate to develop a Reference Architecture that provides organizations with a structured framework for achieving NIS2 compliance and enhancing their cybersecurity resilience.engEnterprise architectureNIS2ArchiMateCybersecuritymaster thesis203990714
