The paper conceived development as a continuum with no static nor predetermined end such that when the aimed paradigm is attained, it subsequently prompts the need and urge to move further for the attainment of much better, much higher and more superior level of developmental achievement so as to get things better and maintain a niche over the existing state of whatever. It examined the dimensions development within the framework of the UN Sustainable Development Goals agenda and what it takes to ensure truly national development. In like manner, national security was viewed beyond securing life and property per se, to encompass all the perspectives of what it takes to preserve a nation at large. The place of ICT in the scheme of contemporary global paradigm especially as it relates to national development and security were highlighted. It concluded that it is natural that no society nor nation will want to be associated with underdevelopment at all fronts of human endeavour. Thus, for systematic national development to be achieved, it must be supported by the security and safety of not only life and property, but should include strategic areas such as: Economy; Education and Literacy; Science and Technology; Law and Order; Politics and International Relations; Reliable and Sustainable Water Supply; Sustainable Environment and Energy Supply; Social Welfare and Empowerment; Culture and Integration; Agriculture and Animal Husbandry; Health and Sanitation; Information and Communication Technology; Road and Transportation; and Good Governance.
