翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Computer security policy ： ウィキペディア英語版 Computer security policy A computer security policy defines the goals and elements of an organization's computer systems. The definition can be highly formal or informal. Security policies are enforced by organizational policies or security mechanisms. A technical implementation defines whether a computer system is ''secure'' or ''insecure''. These formal policy models can be categorized into the core security principles of: Confidentiality, Integrity and Availability. For example the Bell-La Padula model is a ''confidentiality policy model'', whereas Biba model is an ''integrity policy model''. == Formal description == If a system is regarded as a finite-state automaton with a set of transitions (operations) that change the system's state, then a ''security policy'' can be seen as a statement that partitions these states into authorized and unauthorized ones. Given this simple definition one can define a ''secure system'' as one that starts in an authorized state and will never enter an unauthorized state. 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「Computer security policy」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.
