A Protection Profile (PP) is a document used as part of the certification process according to ISO/IEC 15408 and the Common Criteria (CC). As the generic form of a Security Target (ST), it is typically created by a user or user community and provides an implementation independent specification of information assurance security requirements. A PP is a combination of threats, security objectives, assumptions, security functional requirements (SFRs), security assurance requirements (SARs) and rationales. A PP specifies generic security evaluation criteria to substantiate vendors' claims of a given family of information system products. Among others, it typically specifies the Evaluation Assurance Level (EAL), a number 1 through 7, indicating the depth and rigor of the security evaluation, usually in the form of supporting documentation and testing, that a product meets the security requirements specified in the PP. The National Institute of Standards and Technology (NIST) and the National Security Agency (NSA) have agreed to cooperate on the development of validated U.S. government PPs. == Purpose == A PP states a security problem rigorously for a given collection of system or products, known as the Target of Evaluation (TOE) and to specify security requirements to address that problem without dictating how these requirements will be implemented. A PP may inherit requirements from one or more other PPs. In order to get a product evaluated and certified according to the CC, the product vendor has to define a Security Target (ST) which may comply with one or more PPs. In this way a PP may serve as a template for the product's ST. 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「protection profile」の詳細全文を読む スポンサード リンク
