<P>PROBLEM TO BE SOLVED: To enable a designer to easily maintain the logical coherence of an ST, and to enable an evaluator to shorten a time required for the understanding and analysis of the ST. <P>SOLUTION: Prior to the design of security target information F4 based on an ISO/IEC 15408, scenario information F1 including drawing information indicating the corresponding relation of three pieces of information, that is, threat, security countermeasure policy and TOE security function included in the security target information is prepared, and evaluation for the security scenario information is preliminarily received prior to ST design. Thus, it is possible for a designer to easily maintain the logical coherence of an ST, and for an evaluator to shorten a time required for the understanding and analysis of the ST. <P>COPYRIGHT: (C)2009,JPO&INPIT |
