This study evaluates the current practice from owners/ operators of Critical National Infrastructure (CNI) installations throughout Malaysia to ensure the best practice will be taken by owners or operators of CNI to protect CNI from security threats and underline the best performance. Previously, there is no study focusing on success factor as guidelines to all owners and operators of CNI in managing their own installation. The aim of this research is to identify the priority of key success factors towards the performance of CNI installation in Malaysia that focus on three CNI such as water supply, telecommunication and power electricity sectors among all thirteen sectors. The other ten sectors are waterworks, finance, transportation, broadcasting, oil, gas, chemical, radiation, weaponry and security printing. Since there is a high dependency among three sectors to the national security and resilience, this study identifies the critical point on what is the most important way in managing the CNI installation. The main research model includes four key success factors: CNI’s owners and operator’s commitment, business continuity management, physical security protection and partnership dependency/ interdependency towards the performance of CNI. The data were collected by questionnaires and the results were analyzed with SPSS software. Analysis obtained from mean analysis, pearson correlation and multiple regression. The mean analysis is to highlight the current performance of CNI. The pearson correlation is to examine the relationship of four success factors towards the CNI performance and multiple regression suggests that owners and operator’s commitments is the most critical success factors to maintain a good performance in their own CNI installations. This research also discusses the huge implication to the CNI owners and operator’s daily practices and also the policy that can improvised the CNI performance of security and resilience as a whole.
