Industrial Security is a management activity protecting industrial asset of enterprise by application of security elements(physical, IP, conversion security tools) and can be understood as a comprehensive term including software aspect(establishment of policy and strategy, maintenance operation, post- response act, etc.) as well as the operation of hardware elements. In this paper, after recognizing the definition and relative concept of industrial security, the role and its relative laws of the industrial security organizations, the management system and the reality, I will find some problems and submit a reform measure. Furthermore I would like to propose the policy direction to enhance the national competitiveness and to become one of the advanced nations in 21st industrial security through the effective industrial security activities of our enterprises.

Presently in 2018, the security market is requiring progressive development and innovation in the area of security on account of new changes and technologies. This means the rapid and prompt development of the service platforms and service-based information systems. Here, this study is going to examine the process of operating a number of services and obtaining security, not the criteria for selecting particular service in online environment where the various services exist. Within a series of flows to protect the manager's authority about the platforms operated by information systems, and to provide and destroy services, this author limits the entire service platforms of the optimized balance module into four categories maximum for the security of the area apt for illegal invasion and access, and the proper area. Also, about the area with limited security, this researcher again applies subordinate security policy and technology respectively. This author here will suggest a method to provide and to extend safety and security for the information system and also propose the process of applying it as well.

The Internet of Things (IoT) environment has been gradually approaching reality, and although it provides great convenience, security threats are increasing accordingly. For the IoT environment to settle safely, careful consideration of information security is necessary. Although many security measures in the design and development stages of IoT products have been studied thus far, apart from them, the establishment of systems and countermeasures for post management after the launch of IoT products is also very important. In the present paper, a technical and policy post-security management framework is proposed to provide secure IoT environments. The proposed framework defines the concrete response procedures of individual entities such as users, manufacturers, and competent authorities in the case of the occurrence of security flaws after launching IoT products, and performs appropriate measures such as software updates and recalls based on an assessment of the risk of security flaws.

We analyzed security threats and suggested countermeasures about the block chain technologies which has emerged as a core technology of the fourth industrial revolution. We know that increasing the security leads to slow down program processing rate in the block chain systems. The block chain system which is currently an early stage of technological development, to become an economic and social infrastructure, development of technology and active policy implementation will be necessary. We studied on the security threats and countermeasures of the Bit Coin based on block chain. Further research should be undertaken on the possibility that future studies could have a real adverse effect on the integrity of the data.

The focus of this paper is comparing relative effects of government policies for upbringing information security industry from the dynamic point of view. For the purpose of simplicity, these policies are classified into three groups, and then the relative effectiveness of these policy groups is examined using System Dynamics. The three policy groups are composed of technology development policies (TDP), human resource development policies (HDP), and direct supporting policies for overseas expansion (DSP). From the result of the analysis, DSP appears to be the most effective and HDP is the second-best group. By the way, for successful carrying into effect of DSP, marketing manpower should be strengthen. However, current HDP has been focusing on the bringing up technical experts. Therefore, overseas marketing manpower should be reared as well as technicians. Also, the existing infrastructure for overseas expansion for other industries should be shared for DSP of information security industry, because this is essential for success of DSP in terms of timing and costing. Finally, in spite of its low effect, TDP should be maintained continuously. The importance of information security technology is increasing and some countries have already considered these technologies as a core of future national defense. Therefore, we should acquire the competitiveness for a few technologies through continuous development of selected technologies at least.

The policy of US DoD is moving towards implementation of Network Centric Warfare(NCW) concepts. NCW is commonly described as the integration and synchronization of four key interdependent elements such as command and control, sensor system, engagement systems and the network. Therefore the military policy of Korea military is needed to access and examine the policy of NCW communication environment and crypto communication, which is able to apply it. In this case study, We are reviewed the security framework of the concept of network centric warfare in the centering around the US. It is introduced the core technology in the network centric warfare, and it is reviewed the security framework such as, the requirements of security, the characteristics security of global information grid, joint tactical radion system, net centric enterprise services, transformational communication satellite, in the basis of core technology, and analysis the effect of crypto communication relay between command node and surbornate node in NCW environment. This report support the assistance, which is considered the elements of surrounding effects in the varied crypto communication research area of NCW.

Passing 26 years from 1970 when the first satellite was launched into the orbit, Japan developed and successfully launched H-II from Tanegashima Space Center in 1994. During those period, Japanese space policy has experienced a big shake from independent development to technology import from the US, and back again to independent development. In general, the H-II rocket which was manufactured by 100% domestic technology, brings Japan from the old era (experimental stage) to the new era (practical use stage). Fundamental Policy of Japan's Space Activities, which decides such policy as mentioned, was revised in January, 1996 this year after an interval of 7 years. This revised outline confirms the result of Japanese space technology until present and identifies the future direction and framework of her space activities for a period of coming ten years on the basis of a ong-term perspective towards the 21st century. However, when comparing with the last Fundamental Policy in 1989, there seems no big change in it, and a long-term perspective is also not seen there. The description varies on some important points in international space law, like international cooperation, protection of environment, commercial use, etc. In addition, the immaturity as well as the necessity of broader discussion are felt because neither this Fundamental Policy nor The National Defense Program Outline treated any national and international security matters concerning outer space. Considering the present time when Japan enters into the practical use of outer space, such as application, commercial use and launching service, etc, it is doubtful whether new Fundamental Policy was properly planned or not. It seems necessary to use several measures by which the public opinion, opinions from industry and debate on the security are reflected in the policy making.

As the ubiquitous technology has penetrated into almost every aspect of modern life, the research of the security technology to solve the weakness of security in the ubiquitous environment is received much attention. Because, however, today's security systems are usually based on the fixed rules, many security systems can not handle diverse situations in the ubiquitous environment appropriately. Although many existing researches on context aware security service are based on ACL (Access Control List) or RBAC (Role Based Access Control), they have an overhead in the management of security policy and can not manipulate unexpected situations. Therefore, in this paper, we propose a context-aware security service providing multiple authentications and authorization from a security level which is decided dynamically in a context-aware environment using FCM (Fuzzy C-Means) clustering algorithm and Fuzzy Decision Tree. We show proposed model can solve typical conflict problems of RBAC system due to the fixed rules and improve overhead problem in the security policy management. We expect to apply the proposed model to the various applications using contextual information of the user such as healthcare system, rescue systems, and so on.

According to the statistics of the National Industrial Security Center under the National Intelligence Service, 209 national technologies have been leaked abroad in the past 5 years. Small and medium-sized enterprises and leakage by insiders accounted for 73% and 80% of them, respectively. This suggests that all the capabilities for preventing leakage of industrial technology should be focused on small and medium-sized enterprises and leakage by insiders. Related studies have been actively conducted on legal consideration of industrial technology leakage crimes, improvement of industrial security policies, and industrial security measures for preventing leakage of industrial technology, but adequate empirical studies have not been carried out on factors of leakage of industrial technology. In particular, there have been few studies on the effect of the experience of industrial technology leakage and enterprise scale(large enterprise, small and medium-sized enterprise) on achieving results in leakage prevention. Therefore, this study extracted factors affecting performance to prevent industrial technology leakage by analyzing previous related papers and to empirically analyze relationships with performance by applying the TAM model after classifying variables into the TOE framework by characterizing these properties.

Fintech, which means the convergence of finance and information technology, becomes a hot topic in the financial sector. Through innovative activities on financial services, ICT(Information and Communication Technology) is integrated into the overall financial industry, and a new form of financial services could be expected to improve the existing financial system. On the other hand, fintech services are relatively vulnerable to security issues. Due to the process simplication and the channel fusion, the leakage of personal and financial informations, authentication bypass, phishing, and pharming are getting more concerned. In this study we investigated the security risk of fintech services in the viewpoints of service provider, technology adoption, and security policy. The possible countermeasures to reduce those risks are suggested because security is an important criterion for selecting financial services. This study basically offers quantification of the potential security risks and step-by-step control measures about business processes in the fintech services. The suggested security model includes user authentication, terminal security, payment information protection, API(Application Programming Interface) security, and abnormal transaction monitoring. This study might contribute to an understanding of the security risks and some possible measures for mitigating those risks on the practical perspective.
