Governments rely on a range of measures, including

Definitions

The concept of national security remains ambiguous, having evolved from simpler definitions which emphasised freedom from military threat and from political coercion.[1]: 1–6 [2]: 52–54  Among the many definitions proposed to date are the following, which show how the concept has evolved to encompass non-military concerns:

Increasingly, governments organise their

security policies into a national security strategy (NSS);[10] as of 2017, Spain, Sweden, the United Kingdom, and the United States are among the states to have done so.[11][12][13][14] Some states also appoint a National Security Council and/or a National Security Advisor which is an executive government agency, it feeds the head of the state on topics concerning national security and strategic interest. The national security council/advisor strategies long term, short term, contingency national security plans. India
holds one such system in current, which was established on 19 November 1998.

Traditionally, military capabilities were mainly land- or sea-based, and in smaller countries, they still are. Elsewhere, the domains of potential warfare now include the air, space, cyberspace, and psychological operations.[15] Military capabilities designed for these domains may be used for national security, or equally for offensive purposes, for example to conquer and annex territory and resources.
