As a formal document that expresses a set of security requirements for IT products that meets specific consumer needs in the ISO/IEC 15408(CC, Common Criteria) evaluation, protection profiles are developing by many national agencies and companies recently. Since a protection profile is a criteria for security evaluation when the IT systems and products are introduced, the importance of the protection profile is increasing. However, developing protection profiles are still difficult due to lack of detailed methodology and guidance to analyze security environments or to derive security requirements. In this paper, we analyze foreign instances of developing protection profiles and propose a methodology for deriving security requirements through analyzing the TOE security environment.
