Contemporary threats show that there is a need for a fresh look at the issues of both security and defence of the state, which should be perceived as concomitant social phenomena. Although each of them constitutes a separate academic discipline with its own separate area of research, they should nevertheless be regarded as being connected with, and dependent on, each other. Both security and defence of the state can be understood in a narrow and a broader sense, which, in turn, leads to difficulties in research, as in practice it is not always possible to determine what the subject of research is of each of these disciplines. Consequently, the paper discusses the issues of both security and defence of the state.
