For most organizations, a security infrastructure to protect company's core information and their technology is becoming increasingly important. So various approaches to information security have been made but many security accidents are still taking place. In fact, for many Korean companies, information security is perceived as an expense, not an asset. In order to change this perception, it is very important to recognize the need for information security and to find a rational approach for information security. The purpose of this study is to present a framework for information security strategies of companies. The framework classifies companies into eight types so company can receive help in making decisions for the development of information security strategy depending on the type of company it belongs to. To develope measures to classify the types of companies, 12 information security professionals have done brainstorming, and based on previous studies, among the factors that have been demonstrated to be able to influence the information security of the enterprise, three factors have been selected. Delphi method was applied to 29 security experts in order to determine sub items for each factor, and then final items for evaluation was determined by verifying the content validity and reliability of the components through the SPSS analysis. Then, this study identified characteristics of each type of eight companies from a security perspective by utilizing the developed sub items, and summarized what kind of actual security accidents happened in the past.

Purpose: This study analyzed the effect of ethical aspects of CCTV surveillance, such as Security, Responsibility, and Privacy, on consumers' perceptions of unmanned stores. Research design, data, and methodology: The data were collected from 270 participants through an online survey, which was conducted over seven days from October 7 to 13, 2024, with the assistance of an online survey company. The constructs were developed with Delphi Method. And the collected data were analyzed using Delphi Method, SPSS 26, and SmartPLS 4. Results: According to the results, CCTV Security positively influenced the intention to use unmanned stores through the mediation of CCTV Responsibility and consumer attitude. Additionally, Privacy Concerns moderated the relationship between Security and Responsibility. Conclusion: The results of the study show that marketing strategies that emphasize the ethical aspects of CCTV surveillance in unmanned store operations have a positive effect on consumer perception and behavior. When Security and Responsibility are strengthened, consumers' attitudes toward Unmanned stores are formed more favorably and their intention to use unmanned stores is enhanced. In addition Privacy Concerns act as an important factor that moderates the relationship between Security and Responsibility. Therefore, marketers can improve the performance of unmanned stores by communicating the ethical aspects of CCTV operation.

The objective of this paper is to propose the methodology for automated generation of the optimal security defense strategies using evolutionary techniques. As damages by penetration exploiting vulnerability in computer systems and networks are increasing, security techniques have been researched actively. However it is difficult to generate optimal defense strategies because it needs to consider various situations on network environment according to countermeasures. Thus we have adopted a genetic algorithm in order to generate an optimal defense strategy as combination of countermeasures. We have represented gene information with countermeasures. And by using simulation technique, we have evaluated fitness through evaluating the vulnerability of system having applied various countermeasures. Finally, we have examined the feasibility by experiments on the system implemented by proposed method.

This paper is to analyse conflict between the US and China over the South China Sea and Korea's responses. To this end the paper is composed of 6 chapters titled instruction; the current status of South China Sea sovereignty disputes; changes in US and Chinese maritime security strategies and the strategic values of the South China Sea; key issues and future prospects for US-China conflicts in the South China Sea; South Korea's security and diplomatic responses; and conclusion. The recent East Asian maritime security issue has evolved into a global issue of supremacy between the US and China, beyond conflicts over territorial disputes and demarcation among the countries in the region. China is pursuing offensive ocean policy to expand economic growth. The core of the maritime order that the United States intends to pursue is the freedom of navigation in the oceans and the maintenance of maritime access. China is making artificial islands in the South China Sea, claiming the sovereignty of these islands, building strategic bases in East Asia, and securing routes. The United States has developed several "Freedom of Navigation Operations" to neutralize the declaration of the territorial sea surrounding Chinese artificial islands. We can not be free from marine conflicts in the South China Sea and the East China Sea. Regarding the South China Sea dispute, it is expected that the strategic competition and conflict between the two countries will intensify due to China's failure to make concessions of core interests and adherence to the US compliance with international norms. In the midst of conflict over the South China Sea, we need a harmonious balance between our alliance security and economic diplomacy. We must continue our efforts to strengthen the ROK-US alliance but not to make China an enemy. Considering the significant impacts of the oceans on the survival and prosperity of the nation, we must continue to develop our interest in the oceans, appropriate investments and tactical strategies.

This paper is to analyze the trend and implications of the publication of China's defense and security white papers. To this end the paper is composed of 5 chapters titled instruction; publication details and composition of China's defense and security white paper; the gist of the white paper on national defense and security during the Chinese president Xi Jinping era; the implications of Chinese white paper on national defense and security during the Chinese president Xi Jinping era; and conclusion. The Chinese Ministry of National Defense had published seven books every two years since 1998 to 2010. In 1995, the ministry published a white paper titled 'China's arms control and disarmament' for the first time. In 2013, it published a white paper titled 'The Diversified Employment of China's Armed Forces' and 'China's Military Strategy' in 2015. All have the common characteristic of being a propaganda policy reflecting China's strategic calculations. It seems that China has began to publish defense white papers in a proactive manner, due to the following factors: (1)pressure on China to demand military transparency from neighboring countries such as the United States; (2)the erosion of the 'China threat.' and (3)confidence in the achievement of China's military modernization. The 'active defensive strategy' and the 'strong defense strategy' of Si Jinping are implied in the words "China's dream is a dream of a powerful country and dream of a strong nation is essential to construct a strong nation." His these strategies have raised security concerns for neighboring countries. We need to maintain and reinforce strong ROK-US security cooperation, and hedging strategies to harmoniously promote ROK-China economic cooperation.
