National Cyber Security (NCS) is an effort to safeguard nation's assets from loss caused by cyber threats and attacks. In order that NCS development can be performed in a directed and integrated manner, a framework is needed to optimally guide NCS implementation. The NCS framework were identified as previous works comprises twelve components. This paper tries to decompose these twelve main components into sub-component, The sub-components are extracted based on literature review, then validated by a group of experts and practitioners with Delphi technique. 54 sub-components were identified from literature review. Then, the sub-components were updated into 57 sub-components after validated by a group of experts. The findings of this research could be used on the future work for developing a robust Indonesia National Cyber Security Framework.
