Human populations in any given territory are typically organized along the lines that are almost always culturally localized and compelling. While these norms and precepts are often not recognized and legitimized by the central state, they are, nonetheless, what mostly directs the communal lives of people. The concept of internal security is as old as the concept of state, yet the assessment of the Internal Security Architecture of any given geo-socio-political milieu must necessarily bring to the fore, and factor in, layers of securitization that do not depend on the presence of, or input from, state apparatuses. The very idea of internal security architecture is the expression of such a conviction. To research internal security architecture, its definition, components, and dynamics, a research team was formed, comprising expertise in a wide thematic area, ranging from international and domestic law; rule of law; social sciences; anthropology; history; political science; internal/external security science; UN & NATO doctrines (in general); and NATO operations’ planning.
