This Technical Specification provides a guideline for preparation and evaluation of security requirements specifications, referred to as Protection Profiles (PP) in the ISO/IEC 15408 series and in ISO/IEC TR 15446. By a Protection Profile (PP) is meant 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 (OBEs) to be used in an EFC system. This Technical Specification should be read in conjunction with the underlying standards ISO/IEC 15408 and ISO/IEC TR 15446. Although a layman could read the first part of the document to have an overview on how to prepare a Protection Profile for EFC equipment, the annexes, in particular A.4 and A.5, require that the reader be familiar with ISO/IEC 15408. The document uses an OBE with an integrated circuit(s) card (ICC) as an example to describe both the structure of the PP as well as the proposed content.
