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.
Security has to be compared to related concepts: safety, continuity, reliability. The key difference between security and reliability is that security must take into account the actions of people attempting to cause destruction.
Different scenarios also give rise to the context in which security is maintained:
- With respect to classified matter, the condition that prevents unauthorized persons from having access to official information that is safeguarded in the interests of national security.
- Measures taken by a military unit, an activity or installation to protect itself against all acts designed to, or which may, impair its effectiveness.

Famous quotes containing the word security:
“We now in the United States have more security guards for the rich than we have police services for the poor districts. If you’re looking for personal security, far better to move to the suburbs than to pay taxes in New York.”
—John Kenneth Galbraith (b. 1908)
“The reins of government have been so long slackened, that I fear the people will not quietly submit to those restraints which are necessary for the peace and security of the community.”
—Abigail Adams (1744–1818)
“Is a Bill of Rights a security for [religious liberty]? If there were but one sect in America, a Bill of Rights would be a small protection for liberty.... Freedom derives from a multiplicity of sects, which pervade America, and which is the best and only security for religious liberty in any society. For where there is such a variety of sects, there cannot be a majority of any one sect to oppress and persecute the rest.”
—James Madison (1751–1836)
