Communication
Communication (from Latin commūnicāre, meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.
Information
Information is any entity or form that provides the answer to a question of some kind or resolves uncertainty. It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.
Security
Security is freedom from, or resilience against, potential harm (or other unwanted coercive change) from external forces. Beneficiaries (technically referents) of security may be persons and social groups, objects and institutions, ecosystems, and any other entity or phenomenon vulnerable to unwanted change by its environment.
Information
When action grows unprofitable, gather information; when information grows unprofitable, sleep.
Ursula K. Le Guin (b. 1929), American Science Fiction author. The Left Hand of Darkness, Ch. 3 (1969).
Security
To bargain freedom for security is the devil's bargain. Having made the bargain, one enjoys neither freedom nor security.
Gerry Spence, Give Me Liberty! Freeing Ourselves in the Twenty-First Century, Ch. 16 : Security, the One-Way Ticket to Slavery, p. 174 (1998)
Security
No nation can make itself secure by seeking supremacy over all others. We all share responsibility for each other’s security, and only by working to make each other secure can we hope to achieve lasting security for ourselves.
Kofi Annan, Address at the Truman Presidential Museum and Library, Independence, Missouri, USA (11 December 2006)
