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:
“...I lost myself in my work and never felt that marriage would give me the security I wanted. I thought that through the trade union movement we working women could get better conditions and security of mind.”
—Mary Anderson (1872–1964)
“There is one safeguard known generally to the wise, which is an advantage and security to all, but especially to democracies as against despots. What is it? Distrust.”
—Demosthenes (c. 384–322 B.C.)
“The contention that a standing army and navy is the best security of peace is about as logical as the claim that the most peaceful citizen is he who goes about heavily armed. The experience of every-day life fully proves that the armed individual is invariably anxious to try his strength. The same is historically true of governments. Really peaceful countries do not waste life and energy in war preparations, with the result that peace is maintained.”
—Emma Goldman (1869–1940)
