Towards an architecture framework for management platforms in the public sector – Security considerations in times of transformation –

Abstract

Objectives: This paper addresses the digital transformation of public administration in Germany, especially in the context of security aspects of digital transformation of public administration. The importance lies in the creation of flexible, secure, and collaborative structures that ensure both efficiency and data protection and promote a sustainable culture of innovation. Prior Work: The concept builds on international experience with platform architectures and leading practices from the private sector. The study by Doubrava and Sikes (2022) shows that the use of platform and cloud approaches in public administration is not yet widespread, although the ‘Government as a Platform’ model outlined by Tim O'Reilly (2011) promises considerable efficiency potential. The technical architecture is also based on established security standards (e.g. B. ISO 27001) and principles such as defence-in-depth and role-based access control. Approach:The survey was conducted analysing existing platform solutions in the public sector and comparing reference architectures in Switzerland. In addition, empirical experiences from pilot applications, in particular on workflow automation, data integration and user roles, were evaluated. The technical architecture was modelled iteratively based on practical examples and current security requirements. Results:The framework enables a clear separation between innovation space, operational data processing, and protected data management. In the open innovation area, employees and external partners can develop digital solutions collaboratively without access to sensitive data. The data plane ensures the integration and automation of processes through automated workflows, role-based access rights and connectors to specialist applications. The protected data centre ensures the secure processing and storage of application data in compliance with the highest data protection and compliance requirements. Implications: In terms of administrative practice, the framework means a significant reduction in media disruptions, scalability without infrastructure investments and a strengthening of employees' personal responsibility. Researchers will receive a blueprint for the development of secure, flexible platform architectures in the public sector. For decision-makers, architecture offers a way to reconcile innovation, data protection, and economic efficiency. Value:The contribution of the paper lies in the first systematic description and empirical validation of a three-part platform framework for public administration. The combination of an open innovation space, automated data level and protected data centre is new in this form and addresses the specific challenges of administrative digitalization. The framework provides a practical, scalable, and legally secure basis for sustainable digital transformation in the public sector.
