Compliance with information security policies has been an important managerial concern in organizations. Unlike traditional general deterrent theory, this study proposes whistle-blowing as an alternative approach for reducing internal information security policy violations. We build on the theories of planned behavior and rational choice as well as develop a theoretical model to understand the factors that influence whistle-blowing attitudes and intention at both the organizational and individual levels. Our empirical results reveal that altruistic and egoistic concerns are involved in the development of whistle-blowing attitudes. The results not only extend our understanding of whistle-blowing motivation but also offer directions to managers in promoting internal disclosure of information security breaches.

Since NFTs can be used like certificates due to the nature of blockchain, their use in various digital asset trading markets is expanding. This is because NFTs are expected to be actively used as a core technology of the metaverse virtual economy as non-transferable NFTs are developed. However, concerns about NFT security threats are also growing. Therefore, the purpose of this study is to investigate and analyze NFT-related infringement cases and to clearly understand the current security status and risks. As a research method, we determined NFT security areas based on previous studies and analyzed infringement cases and threat types for each area. The analysis results were systematically mapped in the form of domain, case, and threat, and the meaning of the comprehensive results was presented. As a result of the research, we want to help researchers clearly understand the current state of NFT security and seek the right research direction.

The decision to integrate mobile cloud computing (MCC) in higher education without first defining suitable usage scenarios is a global issue as the usage of such services becomes extensive. Consequently, this study investigates the security determinants of the educational use of mobile cloud computing among universities' students. This study proposes and develops a theoretical model by adopting and modifying the Protection Motivation Theory (PMT). The study's findings show that a significant amount of variance in MCC adoption was explained by the proposed model. MCC adoption intention was shown to be highly influenced by threat appraisal and coping appraisal factors. Perceived severity alone explains 37.8% of students "Intention" to adopt MCC applications, which indicates the student's perception of the degree of harm that would happen can hinder them from using MCC. It encompasses concerns about data security, privacy breaches, and academic integrity issues. Response cost, perceived vulnerability and response efficacy also have significant influence on students "intention" by 18.8%, 17.7%, and 6.7%, respectively.

Fog computing diversifies cloud computing by using edge devices to provide computing, data storage, communication, management, and control services. As it has a decentralised infrastructure that is capable of amalgamating with cloud computing as well as providing real-time data analysis, it is an emerging method of using multidisciplinary domains for a variety of applications; such as the IoT, Big Data, and smart cities. This present study provides an overview of the security and privacy concerns of fog computing. It also examines its fundamentals and architecture as well as the current trends, challenges, and potential methods of overcoming issues in fog computing.

The connected car services are one of the most widely used services in the Internet of Things environment, and they provide numerous services to existing vehicles by connecting them through networks inside and outside the vehicle. However, although vehicle manufacturers are developing services considering the means to secure the connected car services, concerns about the security of the connected car services are growing due to the increasing number of attack cases. In this study, we reviewed the research related to the connected car services that have been announced so far, and we identified the threats that may exist in the connected car services through security threat modeling to improve the fundamental security level of the connected car services. As a result of performing the test to the applications for connected car services developed by four manufacturers, we found that all four companies' applications excessively requested unnecessary permissions for application operation, and the apps did not obfuscate the source code. Additionally, we found that there were still vulnerabilities in application items such as exposing error messages and debugging information.

컴퓨터의 활용의 지속적 증가는 전 세계적으로 보안에 대한 인식을 새롭게 하고 있다. 역사적으로 볼 때, 그동안의 연구들은 정보시스템의 보안을 기술적인 대안을 기반으로 접근하여 왔다. 그러나 절차나 논리적 혹은 물리적 장치의 복잡성의 증가로 인해 더 이상 이러한 접근법이 효력을 발생하는 데는 한계가 있다. 즉, 정보기술환경에 대한 보안을 유지하기 위해서는 오늘날에 발생하고 있는 현상을 반영한 포괄적인 이해가 필요하다. 이를 위해 본 연구는 오늘날의 현상을 반영한 포괄적인 정보보안 접근법을 제시하고자 한다.

Objectives : During the past two decades, food deprivation and hunger have been recognized to be not just the concerns of only underdeveloped or developing countries, but as problems for many affluent Western nations as well Many countries have made numerous efforts to define and measure the extent of these problems. Based on these efforts, the theory and practice of food security studies has significantly evolved during the last decades. Thus, this study aims to provide a comprehensive review of the concept and measurement of food security Methods and results : In this review, we introduce the definition and background of food security, we describe the impact of food insecurity on nutrition and health, we provide its measurements and operational instruments and we discuss its applications and implications. Some practical information for the use of the food security index in South Korea is also presented. Conclusions : Food security is an essential element in achieving a good nutritional and health status and it has an influence to reduce poverty The information about the current understanding of food security can help scientists, policy makers and program practitioners conduct research and maintain outreach programs that address the issues of poverty and the promotion of food security.

보안은 소프트웨어 개발에 있어서 주요한 관심사중 하나이다. 보안 전술(Security tactics)은 아키텍처 수준에서 보안의 문제를 해결하기 위한 재사용 가능한 빌딩 블록으로, 소프트웨어 시스템의 구조를 수립하기 위한 일반적인 해결책인 아키텍처 패턴(Architectural Pattern)과 자주 함께 사용된다. 하지만, 아키텍처 패턴에서의 아키텍처 전술은 패턴이나 전술 참여자들이 구조적/행위적으로 어떻게 함께 설계되어야 하는지에 대한 구체적인 이해 없이 보통 개념적으로만 이해되고 만다. 본 논문에서는 대표적인 아키텍처 패턴중 하나인 Broker패턴에서 이와 함께 사용 가능한 보안 전술을 모델 기반으로 표현하고, 실세계에서 어떻게 이 개념이 적용되었는지에 대한 구체적인 사례를 소개한다.
