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.
Information Technology
Information technology (IT) is the use of computers to store, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise. IT is considered to be a subset of information and communications technology (ICT).
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.
Technology
Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is first robustly defined by Jacob Bigelow in 1829 as: "...principles, processes, and nomenclatures of the more conspicuous arts, particularly those which involve applications of science, and which may be considered useful, by promoting the benefit of society, together with the emolument [compensation ] of those who pursue them" .
Information Technology
[ Technology is] the instrumentality for accessing and using free energies in human societies for human and social purposes.

Security
From that point, my universe went on crumbling; new cracks appeared all the time. I could see that the pleasant securities of childhood, all of those warm little human emotions, all of those trivial aims and purposes that we allow to rule our lives, were an illusion. We were like sheep munching grass, unaware that the butcher's lorry is already on its way. I got used to living with a deep, underlying feeling of uncertainty that no one around me seemed to share. It was rather like living on death row.
Colin Wilson in Alien Dawn, pp. 12-13 (1998)
Technology
There is a demon in technology. It was put there by man and man will have to exorcise it before technological civilization can achieve the eighteenth-century ideal of humane civilized life.
René Dubos, A God Within (1972), 216.
