Abstract(in English)	Gordon and Loeb (2002) presented an economic model of characterizing an optimal investment in information security. The model provides us with a persuasive insight, but the security breach probability functions introduced in their paper are too abstract to evaluate an actual information system. We have developed an incremental simulation method of the function to analyze the target system. One of the new findings is that an optimal investment depends on the order of security measures. In addition, we will show that our method provides us a useful measure to better composition of security functions. This paper will report the Incremental Gordon-Loeb method with a case study.
