This study has been conducted to provide data that contribute to increasing efficiency of 'Private Security', which is cooperated by customer, security companies and the police which carried out 'Public Law Enforcement' and controls security companies. To reach this purpose, we investigated the status of the 'Security Alarm Systems' operated by security service companied in Korea, analyzed arising problems, considered the polices for improving the operational quality. 'Electronic Security Systems' will increase working efficiency in performing 'Private Security'. There can be no two opinions on this matter. Therefore, it can be supposed that the improvement of operational quality of 'Electronic Security System' is an important factor to accomplish security services. 'Security Alarm System' is one of the 'Electronic Security System'. The critical problems in operating 'Security Alarm system' are unnecessary response by false alarm and nuisance alarm. To reduce the problems, it is suggested that security specialist officially licensed should improve security planning, installation and maintenance, and the 'Alarm Verification System' should be introduced with appropriate facilities.

The purpose of this study is to examine the operational performances by the investment level of information security in companies. The theoretical background summarized the meaning of information security, management information security, and network security. The research process was carried out in four stages. As a result of the analysis, the level of information security was classified into four groups, and the difference in operational performance was confirmed. According to the categorical regression analysis of the three dependent variables, independent variables such as network threats, non-network threats, executive information security awareness, industry, organizational size, and information security education all affected information security regulations, in-house information security checks, and information security budget investments. The theoretical implications of this study have contributed to updating the latest information security theory. Practical implications are that rational investments should be made on the level of information security of companies.

Purpose - As globalization progresses, complexity also increases, and various factors that threaten port functions are emerging. Accordingly, the demand for port security to prevent the crisis and resilience that quickly recovers its original function after the crisis is also increasing in port operations. However, few studies have examined how to ensure the port security and how the resilience affects operation performance of port and sustainability performance as well. So the study aims to find out how port security affects port resilience and port operational performance, and consequently, this two factors affect socioeconomic and environmental sustainability performance respectively and synthetically. Design/methodology - Confirmatory Factor Analysis (CFA) was first performed to determine the validity of the factors of model and hypothesis test was performed using Structural Equation Model (SEM) to analyze the Port Performance Model, which show the perception logic among port security level, port resilience, operation performance, and sustainability performance. In order to empirically analyze this model, total 264 respondents from port security operators, shipping companies in South Korea were surveyed. Findings - As result of SEM, First, port security level positively affected the resilience (H1) and cargo operational performance (H2) but not in both of the sustainability performances (H3, H4). Second, resilience positively affected only cargo operational performance (H5) and socio-economic sustainability performance (H7). Last, cargo operation performance positively affects the both of sustainability performances (H8, H9). Originality/value - It was confirmed that port security could improve cargo operational performance through ensuring port resilience and eventually increase the socio-economic sustainability. Therefore the study implies that careful integration and management of port security, port resilience, and sustainability are required, along with compromise on sustainable development goals in the social, economic, and environmental area among all stakeholders.

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.

Today's world is generation of Transformation. The Term "Transformation" is widely used in many nations and international organizations such as U.S. and NATO to describe the course of change undertaken by militaries to respond to the new and emerging security environment. Transformation involves all elements of the defense enterprise including Operational Environment, Operational Concepts, Doctrine, Structure and Technologies, within a supportive Cultures context. An Operational Environment is defined as "a composite of conditions, circumstances, and influences that affect the employment of military forces and bear on the decisions of the unit commander." The context for developing future military concept and capability lies essentially within the anticipated boundaries of the operational environment in a collective sense. The joint operational environment is essential to the nation's defense. It describes volatile, complex, and dangerous environment in which the military personnel. organizations, and material will operate. Implications coming forth from joint Operational Environment are but a starting point - many others exist. More and better Implications will come forth as people think about massages of Operational Environment, experiment its characteristics, learn to deal with its threats and scenarios, apply their experience and judgement, and then consider what is required of Korean military doctrine, organizations, training and education, material development, and leadership for operations in the joint Operational Environment.

Major countries are trying to expand the construction of smart factories by introducing ICT such as the Internet of Things, cloud, and big data into the manufacturing sector to secure national-level manufacturing competitiveness in the era of the 4th industrial revolution. In addition, Germany is pushing for Industry 4.0 to build a fully automatic production system through the Internet of Things, and China is pushing for the expansion of smart factories to enhance the country's industrial competitiveness through Made in China 2025, Japan's intelligent manufacturing system, and the Korean government's manufacturing innovation 3.0. In this study, considering the increasing security connectivity of smart factories, we would like to identify security threats in the external connection part of smart factories and suggest security enhancement measures based on domestic and international standard security models to respond to the identified security threats. Eventually the proposed method can be applied by accurately identifying the smart factory security status, diagnosing vulnerabilities, establishing appropriate improvement plans, and expanding security strategies to respond to security threats.

In the Internet of Things (IoT) concept, devices communicate autonomously with applications in the Internet. A significant aspect of IoT that makes it stand apart from present-day networked devices and applications is a) the very large number of devices, produced by diverse makers and used by an even more diverse group of users; b) the applications residing and functioning in what were very private sanctums of life e.g. the car, home, and the people themselves. Since these diverse devices require high-level security, an operational model for an IoT system is required, which has built-in security. We have proposed the societal model as a simple operational model. The basic concept of the model is borrowed from human society - there will be infants, the weak and the handicapped who need to be protected by guardians. This natural security mechanism works very well for IoT networks which seem to have inherently weak security mechanisms. In this paper, we discuss the requirements of the societal model and examine its feasibility by doing a proof-of-concept implementation.

Trusted operating systems (OS) provide the basic security mechanisms and services that allow a computer system to protect, distinguish, and separate classified data. Trusted operating systems have been developed since the early 1980s and began to receive National Security Agency (NSA) evaluation in 1984. The researches about trusted OS are proceeding over the world, and new product type using the loadable security kernel module (LSKM) or dynamic link library (DLL) is being developed. This paper proposes a special type of product using LSKM and specific conditions for operational environment should be assumed.

Network security should be first considered in a distributed computing environment with frequent information interchange through internet. Clear classification is needed for information users should protect and for information open outside. Basically proper encrypted database system should be constructed for information security, and security policy should be planned for each site. This paper describes access control, user authentication, and User Security and Encryption technology for the construction of database security system from network users. We propose model of network encrypted database security system for combining these elements through the analysis of operational and technological elements. Systematic combination of operational and technological elements with proposed model can construct encrypted database security system secured from unauthorized users in distributed computing environment.
