The Parkerian hexad is a set of six elements of information security proposed by Donn B. Parker in 1998. The Parkerian hexad adds three additional attributes to the three classic security attributes of the CIA triad (confidentiality, integrity, availability). The Parkerian Hexad attributes are the following: * Confidentiality * Possession or Control * Integrity * Authenticity * Availability * Utility These attributes of information are atomic in that they are not broken down into further constituents; they are non-overlapping in that they refer to unique aspects of information. Any information security breach can be described as affecting one or more of these fundamental attributes of information. ==Confidentiality== Confidentiality refers to limits on who can get what kind of information. For example, executives concerned about protecting their enterprise’s strategic plans from competitors; individuals are concerned about unauthorized access to their financial records. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Parkerian Hexad」の詳細全文を読む スポンサード リンク
