The purpose of this study is to prevent cyber crime in private company systems by applying secure coding and identify its problems. Three experiments were conducted. In Experiment 1, a security manager was participated and gave advise to the developer to follow secure coding guidelines. In Experiment 2, a security manager did not participate, but let the developer himself committed on secure coding. In Experiment 3, a security manager provided reports on weaknesses of each package source to the developer and the developer was only focused on source development. The research results showed that the participation of a security manager on development raised secure coding compliance rate and finished the project within a given periods. Furthermore, it was better to entrust a security manager with the task of following the secure coding guide than the developer, which raised secure coding compliance rate and achieved project objectives faster. Further implications were discussed.

Multi-attribute risk assessments provide a useful framework for systematic quantitative risk assessment that the security manager can use to prioritize security requirements and threats. In the first step, the security managers identify the four significant outcome attributes(lost revenue, lost productivity, lost customer, and recovery cost). Next. the security manager estimates the frequency and severity(three points estimates for outcome attribute values) for each threat and rank the outcome attributes according to AHP(Analytic Hierarchy Process). Finally, we generate the threat index by using muiti-attribute function and make sensitivity analysis with simulation package(Crystal Ball). In this paper, we show how multi-attribute risk analysis techniques from the field of security risk management can be used by security managers to prioritize their organization's threats and their security requirements, eventually they can derive threat index. This threat index can help security managers to decide whether their security investment is consistent with the expected risks. In addition, sensitivity analysis allows the security manager to explore the estimates to understand how they affect the selection.
