ISO/TS 17574:2017提供了安全要求规范的编制和评估指南，在ISO/IEC 15408（所有部分）和ISO/IEC TR 15446中称为保护配置文件（PP）。 通过保护配置文件（PP），它意味着满足特定需求的一类产品或系统的一组安全要求。一个典型的例子是用于EFC系统的车载设备（OBE）的PP。但是，如果考虑中的子系统已经存在保护配置文件，则本文件中的指南将被取代。

ISO/TS 17574:2017 provides guidelines for preparation and evaluation of security requirements specifications, referred to as Protection Profiles (PP) in ISO/IEC 15408 (all parts) and in ISO/IEC TR 15446. By Protection Profile (PP), it means a set of security requirements for a category of products or systems that meet specific needs. A typical example would be a PP for On-Board Equipment (OBE) to be used in an EFC system. However, the guidelines in this document are superseded if a Protection Profile already exists for the subsystem in consideration.
