The RMF (Cyber Security Risk Management Framework) is a more strengthened U.S. defense cybersecurity framework that is currently used throughout the U.S. federal government beyond the defense sector. In the past decade, the proportion of cyber warfare in non-regular warfare encountered by the United States, especially cyberattacks caused by China and North Korea, has been increasing. In the end, the U.S. is newly establishing an RMF system to prepare a more strengthened cybersecurity policy at the pan-government level, and the U.S. Department of Defense aims to expand the U.S. defense RMF evaluation policy beyond the federal government level. The South Korean military has already applied RMF at the request of the U.S. that notified the policy to apply RMF when obtaining F-35A. The application of RMF by the Korean military is no longer inevitable. Now is the time for the Korean military to seriously think about what to prepare for the early establishment of a successful Korean RMF system.

The National Cyber Capability Assessment(NCCA) could be used as meaningful information for improving national cyber security policy because it provides information on the elements necessary for strengthening national cyber capabilities and the level of each country. However, there were few studies on improving cyber capabilities using the NCCA result in Korea. Therefore, we analyzed the result of National Cyber Power Index(NCPI) conducted by Belfer Center of Harvard Univ. by applying modified-IPA method to derive cybersecurity policy agendas for Korea. As a result, the need to set agendas on surveillance and offensive cyber capability and improve the effectiveness of policy implementation for intelligence and defense was drawn. Moreover, we suggested need for in-depth study of each policy agenda deduced from preceding research data as a future tasks. And it is expected to increase practical use of NCCA for domestic policy analysis by developing and using our own NCCA model which considered analysis framework proposed in this study.

Cyberspace, based on the dramatic development of information and communications technology, has brought enormous benefits to mankind. However, concerns over cyber terrorism and cyber attack are becoming serious. It is time to expand the global dialogue on international security issues in cyberspace. It is imperative to have a common understanding that cyberspace, the infrastructure for prosperity, should not be utilized as a space to create conflicts among states, and that all states agree to build confidence and peace in cyberspace. For this purpose, there are 3 tracks of international cooperations: 1)international cooperation such as UN and Conference on Cyberspace, 2)regional cooperations such as ARF and OSCE. 3)bilateral cooperations such US-Russia Cybersecurity Agreement, US-China presidential level dialogue. This paper will analyze the 1st track of international cooperations of UN and Conference on Cyberspace. With this, Korean government can prepare the forthcoming GGE activities and make our own strategy to deal with the global norms of good behaviour in cyberspace.

Since 2008, large-scale personal information breach incidents have occurred frequently. Even though national education, policy, and laws have been enacted and implemented to resolve the issue, personal information breaches still occur. Currently, individuals cannot confirm detailed information about what personal information has been affected, and they cannot respond to the breaches. Therefore, it is desirable to develop various methods for preventing and responding to personal information infringement caused by breach and leakage incidents and move to privacy protection behaviors. The purpose of this study is to create understanding of personal information security and information breach, to present services that can prevent breaches of personal information, to investigate the necessity of and analyze the potential public demand for such services, and to provide direction for future privacy-related information services.

Science, technology and innovation (STI) has expanded the activity of actors from the traditional physical territory to the cyberspace. Data-driven platform services and markets advance new discussions on cross-border cooperation and cyber security, as well as discourse on sovereignty in cyberspace. These changes are also affecting the hegemony competition between the US and China. In particular, competition for aid to developing countries that are located along major resource transportation routes, such as natural gas and deep sea resources, is fierce. ASEAN is not only a geopolitical military and security point where the US and China powers collide, but its population of 600 million has great potential for the development of the digital economy due to its data resources. In this regard, this article aims to connect the discourse of liberalism and authoritarianism with data regulation and cybersecurity in international development cooperation, and derive implications for ASEAN integration through this. This study has significance as a convergence study that links international political issues related to big data in terms of global governance.

Data security is the planning, implementation and implementation of security policies and procedures for the proper audit and authorization of access to and use of data and information assets. In addition, data serviced through internal / external networks, servers, applications, etc. are the core objects of information protection and can be said to focus on the protection of data stored in DB and DB in the category of information security of database and data. This study is a preliminary study to design a proper Data Security Management System (DSMS) model based on the data security certification system and the US Federal Security Management Act (FISMA). And we study the major security certification systems such as ISO27001 and NIST's Cybersecurity Framework, and also study the state of implementation in the data security manager solution that is currently implemented as a security platform for preventing personal data leakage and strengthening corporate security.

Recently, the US and EU have been institutionally introducing and promoting Coordinated Vulnerability Disclosure(CVD) to strengthen the response to security vulnerabilities in ICT products and services, based on collaboration with white-hat hackers. In response to these changes in cybersecurity, we propose a three-step approach to introduce CVD through the Information and Communications Network Act(ICNA). In the first step, to comprehend the necessity and requirements for legislating CVD, we survey the current situation in Korea and the trends of CVD in the US, EU, and OECD. In the second step, we analyze the necessity for legislating CVD and derive the requirements for its legislation. In this paper, we analyze the necessity for legislating CVD from three perspectives: the need for introducing CVD, the need for institutionalization based on law, and the suitability of the ICNA as the legislation. The derived requirements for CVD legislation include the establishment and publication of Vulnerability Disclosure Policy(VDP), legal protection for white-hat hackers, and designation and role assignments of coordinator. In the third step, we introduce approaches to apply the requirements for CVD legislation to the ICNA, which is the law governing prevention and response to cybersecurity incidents in private sector.
