A security system design supporting tool and method are disclosed, in which security requirements (PP) and security specifications (ST) used for designing a product or a system (TOE) based on CC requirements can be prepared efficiently and uniformly even by ordinary designers other than specialists. In a security system design supporting method, registered PPs and past PP/ST generation cases are so structured as to reuse and/or reference as templates, a draft is automatically generated, and the draft thus generated is additionally modified or corrected by partial automatic generation utilizing a database of past generation cases and partial case accumulated in the generation process thereof.

Security system design supporting method

A security support and evaluation system in accordance with the present invention accepts from an operator via an input unit, a first specification of a system to be evaluated and a second specification of each of the components constituting the system, and then retrieves data from a security countermeasure databasestored in an external storage unitand reads out security countermeasures to be executed to each of the components of the specified system to be evaluated, and then displays on a display unit, the security countermeasures read out in correspondence with each of the components of the specified system to be evaluated, and then accepts from the operator via the input unit, information whether or not each of the security countermeasures is executed, and thereafter evaluates the state of security based on the information and displays evaluation results on the display unit
