This paper provides a series of work on risk management models to identify the assets
and risks. The goal of modeling them is to analyze and calculate meaning of the level of
security in the cyber world. Analyzing and calculating was done by the quantitative method,
so that the investment decision in security tools were expected to be objective, which were
based on performance and situational experiences in an organization. Risk management
was then associated with the calculation of costs that may occur with the point of view of the
financial aspects of ROI/CBA, such as NPV, IRR, and ROI, so it can be measured in the
level of security of the organization and can be maintained within a certain period. Our
model consisted sixteen formulas that can show the increasing level of security based on the
cost.
