Korea's FTA e-commerce regulations are evolving into a standardized norm. However, "location of computing facilities", which was not covered by Korea's existing FTA, was newly established in Korea's first Mega FTA, RCEP. China, a member of RCEP, restricts data movement and requires data localization through its Cybersecurity law. These facts have led to start this study with interest in data-related regulations. It examined country-specific and regulatory characteristics in the process of forming digital trade norms, using the TAPED established by Burri et al. (2020). It also analyzed the current status of introducing norms related to 'data flow', 'data localization' and 'data protection' of the EU, USA and China, which are leading the formation of e-commerce trade norms. Finally, the legal review was conducted to compare the exact meaning of the wording expressed in each agreement for the six recently enacted Mega FTAs and Digital Economic Agreements. These findings are meaningful in that they provided implications for the effectiveness of RCEP and the direction of negotiations on Korea's digital trade norms.

Information security to use information technology(IT) in safety and reliability environment is becoming of great importance. In advanced countries including United States and United Kingdom are consistently expanding budget for information security. Korea also has been a growing interest in information security and Korea government announced plan to develop information security into next-generation growth engine. However, information security budget has increased slightly in recent years, so many national institutions and state governments have budget shortfall to perform information security work. Moreover budget items do not include generic contents about information security and there are confined to some security SW, HW and services. It is necessary to expand information security budget for enhancement national capabilities of information security. In this paper, we analyze the IT and information security budget situation for Korea and United States and propose effective budget expansion and improvement approaches for Korea.

Purpose - This research is intended to analyze the current status and problems of tax benefits in the R&D sector and suggest ways to improve tax credit for research and manpower development expenses when various countries fiercely develop efforts to enhance national competitiveness through increased investment in R&D Design/methodology/approach - This study will examine the current status of the tax support system for domestic and foreign R&D, and suggest improvement measures to expand research and development activities in the future. Findings - First, a plan may be considered to abolish and perpetuate the sunset deadline for tax credit for research and manpower development expenses as in the case of the United States and Japan. This perpetuation can be a proactive measure to actively support long-term R & D investment in companies facing economic decisions under uncertainty. Second, it should be revised to raise the tax credit rate of large corporations, which are shrinking every year, compared to SMEs, so that both large corporations and SMEs can improve their international competitiveness and secure excellent technologies through R & D. Finally, the target technologies for each new growth engine and source technology should be expanded to various fields, including national cybersecurity enhancement technology, aviation engine technology, carbon emission and global cooling technologies, which are areas of interest in major overseas R&D countries, to help active R&D and investment in these areas. Research implications or Originality - This study can find a contribution in comparing and analyzing the national R&D tax support system and presenting improvement measures at a time when the benefits of tax credit for research and manpower development expenses of large companies are decreasing due to frequent tax law revisions and the government's factors of increasing tax revenues. In addition, recent research and development items and research technologies of foreign countries were analyzed by Nature's top 10 major science and technology issues, and advanced technologies that should be applied to target technology areas by new growth engine and source technology were specifically investigated and presented.

Botnets have been exploited for a variety of purposes, ranging from monetary demands to national threats, and are one of the most threatening types of attacks in the field of cybersecurity. Botnets emerged as a centralized structure in the early days and then evolved to a P2P structure. Bitcoin is the first online cryptocurrency based on blockchain technology announced by Satoshi Nakamoto in 2008 and is the most widely used cryptocurrency in the world. As the number of Bitcoin users increases, the size of Bitcoin network is also expanding. As a result, a botnet using the Bitcoin network as a C&C channel has emerged, and related research has been recently reported. In this study, we propose an encrypted botnet C&C communication mechanism and technique in the Bitcoin network and validate the proposed method by conducting performance evaluation through various experiments after building it on the Bitcoin testnet. By this research, we want to inform the possibility of botnet threats in the Bitcoin network to researchers.

With the development of ICT and network, security management of IT infrastructure that has grown in size is becoming very difficult. Many companies and public institutions are having difficulty managing system and network security. In addition, as the complexity of hardware and software grows, it is becoming almost impossible for a person to manage all security. Therefore, AI is essential for network security management. However, since it is very dangerous to operate an attack model in a real network environment, cybersecurity emulation research was conducted through reinforcement learning by implementing a real-life network environment. To this end, this study applied reinforcement learning to the network environment, and as the learning progressed, the agent accurately identified the vulnerability of the network. When a network vulnerability is detected through AI, automated customized response becomes possible.

Cyber hacking attacks and cyber terrorism are damaging to the lives of the people, and in the end, national security is threatened. Cyber-hacking attacks leaked nuclear power cooling system design drawings, cyber accidents such as hacking of Cheongwadae's homepage and hacking of KBS stations occurred. The Act on Information and Communication Infrastructure Protection, Promotion of Information and Communication Network Utilization and Information Protection, and the Personal Information Protection Act remove the responsibility for cyber attacks, but it is difficult to prevent attacks by hackers armed with new technologies. This paper studies the development of cyber security experts for cyber security. Build a Knowledge Data Base for cyber security professionals. Web hacking, System hacking, and Network hacking technologies and evaluation. Through researches on the operation and acquisition of cyber security expert certification, we hope to help nurture cyber security experts for national cyber security.

The purpose of this paper is to ccompare and analyze North Korean cyber attacks and our responses by government, from the Roh Moo-hyun administration to the Moon Jae-in administration. The current conflict of interests on the Korean peninsula, such as the United States, China, and Russia, is leading to a conflict for the leadership of a new world order in cyberspace. Cyber attacks are accelerating and threats are rising. Cyber threats exhibit several characteristics. Above all, it is difficult to identify or track the subject of the threat. Also, with the development of information and communication technology, attack technology has become more intelligent, and it is not easy to prepare a means to respond. Therefore, it is necessary to improve continuous and preemptive response capacity for national cybersecurity, and to establish governance among various actors, such as international cooperation between countries or private experts.

Roblox, the world's No. 1 metaverse platform, has more than 3 billion subscription accounts and more than 150 millionmonthly active users (MAU). Despite such high interest in metaverse, existing studies on analyzing the risk of cyberattacks and security in the metaverse environment is insufficient. Therefore, in this paper, we propose a new steganography-basedcovert communication method in Roblox. In our proposed method, a secret message is hidden into an image by using a function provided in the Roblox Experience environment and then the image is automatically stored in the RobloxExperience participants' devices (PC or Smartphone) so that a malicious software can extract the hidden message fromthe image. By our experiments in the Roblox metaverse environment, we validated our proposed method works and thus want to inform our proposed method can be used in various cyberattacks and crimes such as the spread of secret commands, the establishment of a steganography botnet, and the mass distribution of malicious malware in metaverse platforms.

The Information Security Management System (ISMS) is a protection procedure and process that keeps information assets confidential, flawless, and available at any time. ISMS-P in Korea and ISO/IEC 27001 overseas are the most representative ISMS certification systems. In this paper, in order to understand the relationship between ISMS certification and organizational characteristics, data were collected from Korea Internet & Security Agency (KISA), Ministry of Science and ICT, Information Security Disclosure System (ISDS), Financial Supervisory Service, Data Analysis, Retrieval and Transfer System (DART), and probit regression analysis was performed. In the probit analysis, the relationship with four independent variables was confirmed for three cases: ISMS-P acquisition, ISO/IEC 27001 acquisition, and both ISMS-P and ISO/IEC 27001 acquisition. As a result of the analysis, it was found that companies that acquired both ISMS-P and ISO/IEC 27001 had a positive correlation with the total number of employees and a negative correlation with business history. In addition, the improvement direction of the ISMS-P certification system and information security disclosure system could also be confirmed.

In recent years, there have been frequent incidents of invasion of national defense networks by insiders. This trend can be said to disprove that the physical network separation policy currently applied by the Korea Ministry of National Defense can no longer guarantee military cyber security. Therefore, stronger cybersecurity measures are needed. In this regard, Zero Trust with a philosophy of never trusting and always verifying is emerging as a new alternative security paradigm. This paper analyzes the zero trust establishment trends currently being pursued by the US Department of Defense, and based on the implications derived from this, proposes a zero trust establishment plan tailored to the Korean military. The zero trust establishment plan tailored to the Korean military proposed in this paper includes a zero trust establishment strategy, a plan to organize a dedicated organization and secure budget, and a plan to secure zero trust establishment technology. Compared to cyber security based on the existing physical network separation policy, it has several advantages in terms of cyber security.
