Assets Dependencies Model in Information Security Risk Management

Information security risk management is a fundamental process conducted for the purpose of securing information assets in an organization. It usually involves asset identification and valuation, threat analysis, risk analysis and implementation of countermeasures. A correct asset valuation is a basis for accurate risk analysis, but there is a lack of works describing the valuation process with respect to dependencies among assets. In this work we propose a method for inspecting asset dependencies, based on common security attributes confidentiality, integrity and availability. Our method should bring more detailed outputs from the risk analysis and therefore make this process more objective.
