The general situation of system composition and safety management of high-speed railway terminal is investigated and a comprehensive evaluation index system of operational security is established on the basis of railway laws and regulations and previous research results to evaluate the operational security management of the high-speed railway terminal objectively and scientifically. Index weight is determined by introducing interval eigenvalue method (IEM), which aims to reduce the dependence of judgment matrix on consistency test and improve judgment accuracy. Operational security status of a high-speed railway terminal in northwest China is analyzed using the traditional model of fuzzy comprehensive evaluation, and a general technique idea and references for the operational security evaluation of the high-speed railway terminal are provided. IEM is introduced to determine the weight of each index, overcomes shortcomings of traditional analytic hierarchy process (AHP) method, and improves the accuracy and scientificity of the comprehensive evaluation. Risk factors, such as terrorist attacks, bad weather, and building fires, are intentionally avoided in the selection of evaluation indicators due to the complexity of risk factors in the operation of high-speed railway passenger stations and limitation of the length of the paper. However, such risk factors should be considered in the follow-up studies.

Recently, interest has heightened over 'critical infrastructures' and their reliability in the face of potential terrorist attack. Assault on any of the critical infrastructures as transportation, power, water, telecommunications, and financial services, entails great consequences for their users as well as the other interdependent critical infrastructures. How to protect our vital critical infrastructures is the key question in this paper. The purpose of this article is to suggest the implications for crisis and emergency management to protect the critical infrastructures in our society. For achieving the purpose, we examined the concept of comprehensive security, national crisis, and critical infrastructure and, using the holistic approach, we examined the comprehensive emergency management for suggesting the implications for establishing the critical infrastructure protection system; building up the high reliability organization, organizing and partnering, assessing the risk, preparing first responders, working with private owners of critical infrastructures, working with communities, improving the administrative capacity.

Recently the interests in NII, CALS/EC, and security are rapidly increasing. However, only one of the security issues for CALS implementation, i.e., the security for EDI implementation, has been presented in the literature. No comprehensive discussion about CALS security including other CALS applications exists. This paper intends to present such a comprehensive analysis for the security requirements and standards for the well-recognized two-phase CALS implementation. We present a framework for CALS security encompassing security protocols and systems that are arranged into the framework in terms of the CALS implementation phases, application systems, and communication modes. This framework is followed by brief descriptions of the security services and mechanisms for each CALS application.

This study studied the working relationship between national crisis management and national defense elements from a comprehensive security perspective. The elements of national defense are presented in the Integrated Defense Act. Therefore, by presenting the principles, problems, and alternatives of integrated defense, the study was conducted with the aim of protecting the lives and property of the people in the event of a national crisis and strengthen national security. As a theoretical background, an analysis frame was envisioned based on the four stages of crisis management in the 'Comprehensive Crisis Management Model' and the 'Basic Guidelines for National Crisis Management'. Through this, four domestic and foreign case studies were conducted. As a result of the study, it can be confirmed that related laws, organizations, and public awareness must be provided in order for the national defense elements at each stage of national crisis management to work well. For the completeness of national crisis management, it was suggested that the enactment of the Framework Act on National Crisis Management, the establishment of an integrated defense plan, linked training, C4I for communication, strengthening the capabilities of local government heads, and national defense elements of firefighters.

Nuclear security has been emphasized to ensure the safety of the environment and humans, as well as to protect nuclear materials and facilities from malicious attacks. With increasing utilization of nuclear energy and emerging potential threats, there has been a renewed focus on nuclear security. Korea has made efforts to enhance the regulatory oversight processes, both for general and specific legislative systems. While Korea has demonstrated effective nuclear security activities, continuous efforts are necessary to maintain a high level of security and to improve regulatory efficiency in alignment with international standards. In this study, the comprehensive regulatory oversight framework for the security of Korean nuclear facilities has been investigated. For reference, the U.S. regulatory oversight frameworks for nuclear facilities, with a focus on nuclear security, and the motivations of changes in regulatory oversight framework have been identified. By comparing these regulatory programs and frameworks, insights and considerations for enhancing nuclear security regulations have been identified. A comprehensive security inspection program tailored for the Korean regulatory oversight framework has been proposed, and has been preliminarily applied to hypothetical conditions for further discussion.

The growth in computer use has ushered increased concerns of information security throughout the world. Historically, researchers interested in the security of information systems have long investigated extensively themselves with building technological countermeasures in order to prevent several information security problems. However, due to infusion of more procedures and logical or physical devices within the information environment, no system can be completely secure. Therefore, keeping IT environment safe demands a more comprehensive understanding of the phenomenon, which requires broadening information security far beyond the technical aspects. This study is aimed at proposing a information security framework from holistic view.

Civil aviation cybersecurity challenges are global in nature and must be addressed using global best practices and the combined efforts of all stakeholders. This requires the development of comprehensive international strategies and detailed plans for their implementation, with appropriate resources. It is important to build such strategies on a common methodology that can be applied to civil aviation and other interrelated critical infrastructure sectors. The goal of the study was to determine the methodological basis for developing an international civil aviation cybersecurity strategy, taking into account existing experience in strategic planning at the level of international specialized organizations. The research was conducted using general scientific and theoretical research methods: observation, description, formalization, analysis, synthesis, generalization, explanation As a result of the study, it was established the specifics of the approach to formulating strategic goals in civil aviation cybersecurity programs in the documents of intergovernmental and international non-governmental organizations in the aviation sphere, generally based on a comprehensive vision of cybersecurity management. A comparative analysis of strategic priorities, objectives, and planned activities for their implementation revealed common characteristics based on a single methodological sense of cybersecurity as a symbiosis of five components: human capacity, processes, technologies, communications, and its regulatory support. It was found that additional branching and detailing of priority areas in the strategic documents of international civil aviation organizations (by the example of Cybersecurity Strategy and Cybersecurity Action Plan) does not always contribute to compliance with a unified methodological framework. It is argued that to develop an international civil aviation cybersecurity strategy, it is advisable to use the methodological basis of the Cyber Security Index.
