Security in Data Warehouses

Landwehr (2001) defines how the etymological roots of the term “secure” are found in “se” which means “without,” or “apart from,” and “cure,” i.e. “to care for,” or “to be concerned about”. While there are many definitions of the primary requirements of security, the classical requirements are summarized by the acronym CIA. CIA is the acronym for confidentiality, integrity, and availability. All other security requirements such as non-repudiation can be traced back to these three basic properties. Avizienis (2004) defines confidentiality as the absence of unauthorized disclosure of information, integrity as the absence of improper system alterations and availability as readiness for correct service.
