The expanded application of digital controls has raised the issue of cyber security for nuclear facilities. To cope with this, the cyber security technical standard RS-015 for Korean nuclear facilities requires nuclear system developers to apply security functions, analyze known vulnerabilities, and test and evaluate security functions. This requires the development of procedures and methods for testing the suitability of security functions in accordance with the nuclear cyber security technical standards. This study derived the security requirements required at the device level by classifying the details of the technical, operational and administrative security controls of RS-015 and developed procedures and methods to test whether the security functions implemented in the device meet the security requirements. This paper describes the process for developing security function compliance test procedures and methods and presents the developed test cases.

Recently, research outcome is frequently leaked in the process of progressing domestic R&D. Security system such as research security law and manual is implemented to prepare these leakage. However piecemeal solutions, simply technological measures, have a limit. Consequently, this study organizes a integrated research security framework by designing multidimensional security measures based on the R&D life cycle perspective. Concretely, this study constructs various control items predicated on law, moreover reviews the applicability of research security assessment items.

As numerous security breaches on a variety of information assets such as personal information, corporate secrets, computer servers, and networks have occurred, information security has emerged as a critical social issue. However, researches on economically rational information security decision-making have been few. Such researches are especially rare in South Korea where information security is considered to be a discipline of engineers. This study aims to identify the preferred themes and methodologies of information security economics research in the field of information systems by reviewing papers published in Management Information Systems Quarterly (MISQ), Information Systems Research (ISR), European Journal of Information Systems (EJIS), Management Science (MS), and Information and Management (I&M). We hope that the results of the study will be helpful in rational managerial or policy decision-making for practitioners and suggest future research topics for researchers.

The government is continuously expanding its national R&D investment to actively respond to the advent of the $4^{th}$ industrial revolution era and to develop the national economy. The R&D structure is likely to be liberalized as the paradigm shifts from the pursuit type R&D to the leading type R&D, and R&D capacity enhancement that focuses on researchers' creativity is emphasized. Such changes in R&D environment will increase the risk of security accidents such as leakage of research information. In addition, security policy for protection of research result should be the Researcher-Centric Security and security policy should be changed. This study explored transforming the research security system into the Researcher-Centric Security system so that researchers can voluntarily implement necessary security measures in the course of conducting research.

As the importance of R&D increases amid the paradigm of technology hegemony competition, countries around the world are increasing investment in R&D, at the same time, making effrots to portect R&D. Centering to technology-leading countries, such as Korea, the United States and Japan, they reorganize research security regulations to protect national R&D; however, the burden of compliance for researcher and research institutes is still high. Korea enacted the National R&D Innovation Act and the Enforcement Decree of the same Act to establish an integrated and systematic research security support system, but research institutes and researchers still lack understanding and practice of research security. In order to strengthen researcher's research security compliance, this study organized information requirements for each security management area through domestic and foreign research security laws and prior research analysis, and designed research security information requirements items centered on researchers. The designed information requirements are meaningful in that they were designed by considering both the management area and the stage of R&D, focusing on researchers performing R&D in the field. Based on the designed information requirements items, it is expected that systematic security management will be possible at the research site, which will ease the security burden of researchers and improve research security compliance at the research and development site.

Internet attack incidents have steadily increased along with the increase in Internet users. To protect systems and networks from these attacks, advanced security systems have been developed. Now that these security systems are operating, their successful management is more important than the purchase and establishment of new information security systems. The acquisition of good systems is ineffective and financially wasteful unless they are managed properly. Adequate management policy has recently become the focus of users. In other words, for companies and educational institutions with their domains, capital expenses are enormous to bear, and good security staffs are difficult to find, for which reasons outsourcing vendors or Managed Security Service Providers (MSSPs) that manage and operate the information security systems of certain domains become very appealing. Today, customers expect ISPs to perform MSSP services that used to be carried out by the security companies. This document presents the role and necessity of ISPs as MSSPs.

Public institutions invest about half of the information protection budget annually to introduce information security products and information protection services in order to prevent cyber terrorism and establish organizational security. However, research on whether introduced information security products has a positive influence on improving the information security level of the actual institution is in an incomplete state, and accordingly, There are problems such as the measurement of the investment effect of the information security product introduced in the organization and the difficulty in selecting the optimum information security product that the agency actually needs. In this paper, prior research will conduct research on the influence of the introduction of information security products on the improvement of information security level of organization through analysis of operational data of inadequate information security products, and based on the research results, It would be useful to use it for information security practices such as optimal product selection and internal security policy formulation through validation of the introduction of information security products of public institutions.

Highlighted by recent security breaches including Google, Western Energy Company, and the Stuxnet infiltration of Iranian nuclear sites, Cyber warfare attacks pose a threat to national and global security. In particular, targeted attacks such as APT exploiting a high degree of stealthiness over a long period, has extended their victims from PCs and enterprise servers to government organizations and critical national infrastructure whereas the existing security measures exhibited limited capabilities in detecting and countermeasuring them. As a solution to fight against such attacks, we designed and implemented a security monitoring system, which shares security information and helps cooperative countermeasure. The proposed security monitoring system collects security event logs from heterogeneous security devices, analyses them, and visualizes the security status using 3D technology. The capability of the proposed system was evaluated and demonstrated throughly by deploying it under real network in a ISP for a week.
