Data
Data ( DAY-tə, DAT-ə, DAH-tə) is a set of values of qualitative or quantitative variables.
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 Security
Information security, sometimes shortened to InfoSec, is the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction of information. It is a general term that can be used regardless of the form the data may take (e.g., electronic, physical). Information security's primary focus is the balanced protection of the confidentiality, integrity and availability of data (also known as the CIA triad) while maintaining a focus on efficient policy implementation, all without hampering organization productivity. This is largely achieved through a multi-step risk management process that identifies assets, threat sources, vulnerabilities, potential impacts, and possible controls, followed by assessment of the effectiveness of the risk management plan.
Management
Management (or managing) is the administration of an organization, whether it is a business, a not-for-profit organization, or government body. Management includes the activities of setting the strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its objectives through the application of available resources, such as financial, natural, technological, and human resources. The term "management" may also refer to those people who manage an organization.
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
[T]he production of security should, in the interests of the consumers of this intangible commodity, remain subject to the law of free competition. … [N]o government should have the right to prevent another government from going into competition with it, or to require consumers of security to come exclusively to it for this commodity.
Gustave de Molinari, tr. J. Huston McCulloch, §II of The Production of Security (Auburn, AL: Ludwig von Mises Institute, 2009; orig. 1849), pp. 22–23.
Manager
Everybody has his own theatre, in which he is manager, actor, prompter, playwright, sceneshifter, boxkeeper, doorkeeper, all in one, and audience into the bargain.
J. C. and A. W. Hare, Guesses at Truth, in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 4-6.
Management
In the long-run the workman may be as necessary to his master as his master is to him, but the necessity is not so immediate.
Adam Smith (1776) The Wealth of Nations Chapter VIII, p. 80
