This paper summarizes six years of experience (2011-2016) at the Ministry of Transport, Information Technology and Communications and the National Revenue Agency to develop capacity and cybersecurity readiness. It is based on a number of projects, which adopt a consistent approach for change management and restructuring in public administration in view of cyber security standards. In addition, this paper outlines how digital technologies and simulation tools have been employed in the process of cyber security deployment and capacity development as an example of good practices in the public sector transformation. Using Computer assisted exercises, a special technical platform, training and exercise management system provides an integrated framework across the Public Sector for enhancing the effectiveness and achieving interoperability and analytical capability.
