Etymology

The word 'secure' entered the English language in the 16th century. It is derived from Latin ''securus'', meaning freedom from anxiety: ''se'' (without) + ''cura'' (care, anxiety).


Overview


Referent

A security
referent A referent () is a person or thing to which a name – a linguistic expression or other symbol – refers. For example, in the sentence ''Mary saw me'', the referent of the word ''Mary'' is the particular person called Mary who is being spoken of, ...
is the focus of a security policy or discourse; for example, a referent may be a potential beneficiary (or victim) of a security policy or system. Security referents may be persons or social groups, objects, institutions, ecosystems, or any other phenomenon vulnerable to unwanted change by the forces of its environment.Barry Buzan, Ole Wæver, and Jaap de Wilde, ''Security: A New Framework for Analysis'' (Boulder: Lynne Rienner Publishers, 1998), p. 32 The referent in question may combine many referents, in the same way that, for example, a nation state is composed of many individual citizens.


Context

The security context is the relationships between a security referent and its environment. From this perspective, security and insecurity depend first on whether the environment is beneficial or hostile to the referent, and also how capable is the referent of responding to its/their environment in order to survive and thrive.


Capabilities

The means by which a referent provides for security (or is provided for) vary widely. They include, for example: * ''Coercive capabilities'', including the capacity to project coercive power into the environment (e.g.

Effects

Any action intended to provide security may have multiple effects. For example, an action may have wide benefit, enhancing security for several or all security referents in the context; alternatively, the action may be effective only temporarily, or benefit one referent at the expense of another, or be entirely ineffective or counterproductive.


Contested approaches

Approaches to security are contested and the subject of debate. For example, in debate about national security strategies, some argue that security depends principally on developing protective and coercive capabilities in order to protect the security referent in a hostile environment (and potentially to project that power into its environment, and dominate it to the point of strategic supremacy). Others argue that security depends principally on building the conditions in which equitable relationships can develop, partly by reducing antagonism between actors, ensuring that fundamental needs can be met, and also that differences of interest can be negotiated effectively.

Perceptions of security

Since it is not possible to know with precision the extent to which something is 'secure' (and a measure of vulnerability is unavoidable), perceptions of security vary, often greatly. For example, a fear of death by earthquake is common in the United States (US), but slipping on the bathroom floor kills more people;Bruce Schneier, ''Beyond Fear: Thinking about Security in an Uncertain World'', Copernicus Books, pages 26–27 and in France, the United Kingdom and the US there are far fewer deaths caused by

Security concepts (examples)
