National Security is increasingly becoming tricky given the growing complexities of systems and the obvious challenges of threat, risk and danger. While state machinery tries to deal with the emerging questions, social structures and institutions, the media are often invited to evaluate these social systems, not just in the mediation of conflicts that raise issues on national security, but with regard to how the issues are portrayed and how citizens engage in the discourse in public communication. While portrayals can be inflammatory, and capable of aggravating tension, it can also play a meditating role through the mitigation of conflicts or the building of consensus. This paper, therefore, explores the critical compass of citizenship as a unit of the polity and the indispensability of public communication in the matrix. It dissects the place of the media in contextualizing discourse on national security and the role of the citizens, to imagine the intermediating functions of the media in national security. The changing phase of citizen and public communication is contextualized, as well as the meanings are drawn from information (dis)order, securitization and inclusion and exclusion, through the collective action of citizenry.
