Security is the degree of protection to safeguard a nation, union of nations, persons or person against danger, damage, loss, and crime. Security as a form of protection are structures and processes that provide or improve security as a condition. The Institute for Security and Open Methodologies (ISECOM) in the OSSTMM 3 defines security as "a form of protection where a separation is created between the assets and the threat". This includes but is not limited to the elimination of either the asset or the threat. Security as a national condition was defined in a United Nations study (1986): so that countries can develop and progress safely.

Famous quotes containing the word security:

    In the long course of history, having people who understand your thought is much greater security than another submarine.
    J. William Fulbright (b. 1905)

    Modern children were considerably less innocent than parents and the larger society supposed, and postmodern children are less competent than their parents and the society as a whole would like to believe. . . . The perception of childhood competence has shifted much of the responsibility for child protection and security from parents and society to children themselves.
    David Elkind (20th century)

    A well-regulated militia being necessary to the security of a free State, the right of the people to keep and bear arms shall not be infringed.
    U.S. Constitution, Second Amendment.
