The study is intended to examine awareness of safety as a differentiated service strategy and t to induce offer of more competitive services to the internal and external consumers in service industry of the South Korea. In the pursuit of this purpose, the typical occupations of the service industry targeted hotel employees and this study investigate the policy effectiveness of security management in Korea hotels. Specifically, this study was conducted by survey and involved major hotel(Seoul, Busan, Gyeongsangnam-do, Gyeongsangbuk-do) across the country. This survey went through feasibility study by major hotels managers. The results were as follows: Findings of the study suggested that most of disaster management stages did not have a statistically significant relationship with the policy effectiveness of security management. Only, repair stage have significant impact on the policy effectiveness of security management. This finding was found to be attributable to the fact that hotel employee would be concentrated in the tangible results of security management.

2001. 9. 11 aviation terror showed us that there are lots of problems in aviation security and we need efficient counter-plans. According to this event, many countries are coming up with various countermeasures. After first hijacking in 1950, the aviation terror is occurring with more various methods until these days. And the scale is bigger than former so they're making much bigger damages. Especially, the case of 9.11 terror attracted people's eye of the world because of enormous casualties and damages. It aroused many people's self-awakening therefore as an important factor the security is given much weight in the aviation safety. In order to keep the step like this tendency and the development of aviation security, beginning with America lots of countries of the world are pursuing diverse aviation security's counter-plans of new side. At this point of time, for our development in aviation industry we should make efficient aviation security countermeasures. In this study, We compared our aviation security activities with major countries after 9.11 terror.

In this study, major research trends at home and abroad were compared and analyzed in order to derive key research fields in the financial security field and to suggest directions. To this end, 689 domestic and 20,736 foreign data were collected from domestic and international academic journal DB, and major research fields related to financial security were extracted through LDA analysis. After that, hot & cold topics were derived through time series linear regression analysis. As a result of the analysis, studies related to government policy issues, personal information, and accredited certification were derived as promising research fields in Korea. In the case of foreign countries, related studies were drawn to develop advanced security systems such as cryptographic protocols and quantum security. Recently, it has become possible to apply various security technologies in Korea through the abolition of public certification. Accordingly, as changes in promising research fields are expected, the results of this study are expected to contribute to the establishment and development of a successful roadmap for domestic financial security.

In an environment where computer-related technologies are rapidly changing, cyber threats continue to emerge as they are advanced and diversified along with new technologies. Therefore, in this study, we would like to collect security-related news articles, conduct LDA topic modeling, and examine trends. To that end, news articles from January 2020 to August 2023 were collected and major topics were derived through LDA analysis. After that, the flow by topic was grasped and the main origin was analyzed. The analysis results show that ransomware attacks in 2021 and hacking of virtual asset exchanges in 2023 are major issues in the recent security sector. This allows you to check trends in security issues and see what research should be focused on in the future. It is also expected to be able to recognize the latest threats and support appropriate response strategies, contributing to the development of effective security measures.

The operating system (OS) of mobiles or embedded devices is based on the Linux kernel. These OSs request random numbers from the Linux kernel for system operation, such as encryption keys and security features. To provide random numbers reliably, the Linux kernel has a dedicated random number generator (Linux Pseudo Random Number Generator, LPRNG). Recently, LPRNG has undergone a major structural changes. However, despite the major changes, no security analysis has been published on the structure of the new LPRNG. Therefore, we analyze these structural changes as a preliminary study to utilize the security analysis of the new LPRNG. Furthermore, the differences between before and after the changes are divided into cryptographic and performance perspectives to identify elements that require security analysis. This result will help us understand the new LPRNG and serve as a base for security analysis.

With the terrorist attacks on 11 September 2001, the ships and their crew' safety and security have become a major issue in the maritime industries, In high-risk terrorism, not only ship owners and port authorities but also crew members on board should take precautions in the conduct of their business. In this paper, the vulnerability and essential elements in overall security of merchant ship are analyzed with a discussion in depth of the concept and principles of maritime security of merchant ship are analyzed with a discussion in depth of the concept and principles of maritime security management. And then, ship's security model and security system to reduce security rish and to minimize damage are proposed.

Internet environment and innovative ICT(information and communication technology) have brought about big changes to our lifestyle and industrial structure. In spite of the convenience of Internet, various cyber incidents such as malicious code infection, personal information leakage, smishing(sms + phishing), and pharming have frequently occurred. Information security must be recognized as a key and compulsory element for surviving in a global economy. Strategic roles of information security have recently been increasing, but effective implementation of information security is still a major challenge to organizations. Our study examines the influencing factors of information security and investigates the causal relationship between information security maturity level and organizational performance through an empirical survey. According to the results of our study, personal, organizational, technical, and social factors affect organizations's information security maturity level altogether. This result suggests that when dealing with security issues, the holistic and multi-disciplinary approaches should be required. In addition, there is a causal relationship between information security maturity level and organizational performance, and organizations aim to establish the efficient and effective ways to enhance information security maturity level on the basis of the results of this study.

As communication is becoming increasingly prevalent and especially communication architecture is more relying on the open standard communication protocols, the security issues become major concerns. In this paper we consider possible cyber attacks in the applications based on the current distribution communication architecture, and then derive the security goals. Next we propose how the security algorithms can be adapted to achieve these security goals. We intend to adapt the most efficient ways of secure message exchange, taking the resource-constrained FRTUs into account Finally we show some experiments to validate the protocols.
