ABSTRACT

The National Information Security Index (NISI) is an analytical and quantitative tool for mapping out factors that contribute to the security of the network, service, and personal information. It measures not only summary indicators that help to focus on the overall level, but also multi-dimensional indicators that identify the vulnerabilities independently. The NISI can be used as a tool to enhance the understanding of the current level of information security, so that the information security policy can be shaped and evaluated in the most informed manner. This study aims to develop a quantitative model and two composite indices by which the nationwide level of information security can be determined. Two indices were developed to represent the degree of protection and the frequency of internet incidents by malicious activities; NISI and Side-Effects Index (SEI) The results with time series data show that the level of information security has been improved about 5.8% on average from 2002 to 2005. On the other hand, the frequency of internet incidents has been decreased. While any attempt to simplify the assessment with a single measure is admittedly artificial, the NISI has significantly improved our understanding of how various attributes affect the information security at the national level.
