Acceptance of this paradox by the information security community was immediate, because it was consistent with the professional experiences of this group. Mayfield’s Paradox points out that, at some point of the curve, additional security becomes unrealistically expensive. Conversely, at some point of the curve, it becomes unrealistically expensive to add additional users. Based on the Paradox the Menz brothers developed the "Menz Theorems of Information and Physical Security". The theorems present two formulas covering access and security of both information systems and physical facilities. They are used to help determine allocation of resources and response levels. ==Notes== 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「Mayfield's paradox」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
