This article analyzes the external factors that influence national security from the perspective of propaganda and disinformation. At the same time, the implications of internal factors on national security, which accentuate the impact of challenges from outside the country, are not neglected. This allows the authors to highlight the need to develop a strategic communication process at national level. Thus, the authors emphasize that strategic communication is an integral part of the government’s efforts to achieve national political, economic, societal, security and defense objectives. Respectively, strategic communication, as a process, can contribute to a more efficient orchestration of government activities, integrating various activities within the instruments of power, in order to strategically influence and form the national resilience.
