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.
Security
Everywhere, when societies originate, we see the strongest, most warlike races seizing the exclusive government of the society.  Everywhere we see these races seizing a monopoly on security within certain more or less extensive boundaries, depending on their number and strength.And, this monopoly being, by its very nature, extraordinarily profitable, everywhere we see the races invested with the monopoly on security devoting themselves to bitter struggles, in order to add to the extent of their market, the number of their forced consumers, and hence the amount of their gains.
War has been the necessary and inevitable consequence of the establishment of a monopoly on security.
Gustave de Molinari, tr. J. Huston McCulloch, §VI of The Production of Security (Auburn, AL: Ludwig von Mises Institute, 2009; orig. 1849), pp. 34–35.
Security
We must plan for freedom, and not only for security, if for no other reason than only freedom can make security more secure.
Karl Popper, The Open Society and Its Enemies (1945)
Information
Do not seek for information of which you cannot make use.
Anna C. Brackett (1836–1911), American author. The Technique of Rest, Ch. 2 (1892).
