The article argues for the need to develop a culture of security, which must be a benchmark of conduct, morals, education and training; to promote the ensemble of information, attitudes, beliefs and values through which the individual relates them to the political, military and economic system, which characterizes the level of ensuring security to each individual and to society as a whole. The need to develop a culture of security and to educate the population in this spirit derives from the diversification of threats to national security and how they are spread. Educating and promoting a strong culture of security will prevent the transformation of vulnerabilities into threats to national security. Due to the fact that the citizens are at the basis of the development of the culture of security, education in this field brings a considerable contribution in the proper promotion of the given culture at all levels of education, based on the principle of lifelong learning. The actors concerned with security education use several means of training through concrete actions, such as: meetings with civil society representatives, round tables, conferences, debates or various partnerships with academic or research institutions, scientific communication sessions, meetings with pupils and students in educational institutions of all levels, trainings with active young people, introduction of course units on the development of the culture of security, with all its components, from healthy living and personal development to work protection, civil protection, education for society, etc. Therefore, the culture of security is vital in the information age we are going through, in which we all need guidelines at both personal and state level. A citizen with a high culture of security is the natural and invaluable partner for the community he belongs to and for the nation.
