This paper discuss secure information flow analysis and its visualization. Information leak is defined as existence of information flow from variables which have user's private informations to variables that anyone can access. Secure information flow analysis has been made to decide of whether the information leak is or not. There are many researches for secure information flow analysis concerning high level programming languages. But actually, programs that user executes don't have program source code represented in high level programming language. Thus there is need for analysis of program represented in low level language. More to analysis, visualization of analysis is very important. So, this paper discuss visualization of secure information flow analysis. In this paper, Mini x86 Assembly Language which is subset of x86 assembly language is defined and secure information flow analysis of program is proposed. In addition, this paper defines transfer function that is used for analysis and shows how to visualize control flow graph.

The purpose of this study is to examine what are the important variables for information security compliance and whether the information security investment by the industry is different. To comply with the information security policies, the organization must establish measures to prevent or resolve information security incidents. This research process consists of four stages, and the analysis method was conducted with the categorical regression analysis and the correspondence analysis. The first analysis analyzed the independent variables that affect security regulations compliance. The rest of the analysis was conducted by industry in the order of security compliance regulations, manpower investment, and budget investment. As a result of the first analysis, this had positive effects on an organization and personal information protection awareness, joint operation organization of information protection, manpower and budget investment, corporate size, and industry. The correspondence analysis was conducted from the second analysis to the fourth analysis and it analyzed the differences in information security investment by industry. The second analysis showed that the construction industry, science and technology industry, and finance industry have higher compliance with security regulations than other industries. The third analysis showed that the financial industry and the science and technology industry were higher than other industries. The last analysis showed that the financial industry was higher than other industries. The theoretical contribution of this study provided the basis for updating the information security theory. The practical contribution of this study requires government support to reduce information security deviations by industry.

While conventional business administration-based information technology management methods are applied to the risk analysis of information systems, no security risk analysis techniques have been used in relation to information protection. In particular, given the rapid diffusion of information systems and the demand for information protection, it is vital to develop security risk analysis techniques. Therefore, this paper will suggest an ideal risk analysis process for information systems. To prove the usefulness of this security risk analysis process, this paper will show the results of managed, physical and technical security risk analysis that are derived from investigating and analyzing the conventional information protection items of an information system.

This exploratory study aims to understand the potential of log data analysis and expand its utilization in user research methods. Transaction log data are records of electronic interactions that have occurred between users and web services, reflecting information-seeking behavior in the context of digital libraries where users interact with the service system during the search for information. Two ways were used to analyze South Korea's National Digital Science Library (NDSL) log data for three days, including 150,000 data: a log pattern analysis, and log context analysis using statistics. First, a pattern-based analysis examined the general paths of usage by logged and unlogged users. The correlation between paths was analyzed through a χ² analysis. The subsequent log context analysis assessed 30 identified users' data using basic statistics and visualized the individual user information-seeking behavior while accessing NDSL. The visualization shows included 30 diverse paths for 30 cases. Log analysis provided insight into general and individual user information-seeking behavior. The results of log analysis can enhance the understanding of user actions. Therefore, it can be utilized as the basic data to improve the design of services and systems in the digital library to meet users' needs.

정보 자산에 대한 위험 분석은 주로 한국정보통신기술협회나 국제표준화기구의 표준에 따라 이루어지고 있다. 그 과정은 자산분석, 위협분석, 취약성분석, 대응책분석의 순서로 이루어져있다. 이 과정은 분석 대상, 즉 자산을 명확히 파악하는 것부터 시작된다. 기존의 방법은 그 대상을 물리적 자산에 따라 분류하는 것이 일반적이다. 한편, 국제결제은행 규약이 제시하는 방법에 따르면 위험 분석의대상을 운영에 따른 분류를 통해 규명하게 된다. 본 논문에서는 물리적 자산 중심의 기존 방법과 더불어 업무 중심의 분석 방법이 유용할 수도 있음을 보이고자 하였다. 컨조인트 분석 기법을 활용하여 상황에 따라 물리적 자산 중심의 방법과 업무 중심의 방법의 유용성의 차이를 예를 들어 분석하였다.
