Since 2002, many domestic companies have been certified for ISMS. On the other hand, certification, such as the need for ost-effectiveness evaluation, is not specifically enforced. Therefore, for more than 10 years, the ISMS implementation and certification system has been used for performance and cost effective business management. In this study, a model for analyzing the effect of certification organizations, ISMS development, and an analysis of the effect of a standardized system for the study was prepared. To this end, the existing maintenance organizations ISMS certification survey was conducted through an analysis of the economic effects. ISMS certification continues to expand or maintain the policy for improvement. The survey data collected by the analysis mechanism for the economic effects of CVM was analyzed.

Security threats in the 4th Industrial Revolution have expanded to the issue of safety, but the environment for information security of domestic companies is still at a low level. This study aims to propose policy implications by empirically analyzing factors affecting investment intention. We investigated the state of information security and protection behavior and expanded UTAUT to investigate correlations. The results showed that information assets affect facilitating conditions, and perceived and new concerns have impacts on social influence. Social influence affect experience and habits, but the impact on security investment intentions was rejected. Facilitation conditions, previous experiences and habits have great influences on investment intention, new service security investment intention. The influence of perceived and new concern are low or rejected. There are moderating effects between types of business, size, security organization, experience of infringement, security personnel ratio, and personal information collection. This study will help to establish policies for enhancing the level of information security.

The forces to protect people's life and property against the enemy attack is an organization which is regulated by the constitutional law. In terms of nature, its security is a significant factor to determine success or failure for the war. However, recently the 4th industrial revolution represents the rapid change in the advancement of civilization and technology. It can influence on the environment of military security which can make various changes. Unless taking proper action againsty these changes, it can inflict a vital harm for the organization of forces and its internal security. In this aspect, this study discuss new threats of the military security, above all, the most technical improvements and harms for the drones in terms of security. In addition, the advantages and disadvantages of drones which can influence on the ragions of military command and control, information operations, maneuvers, firepower, operation sustainment supports are analyzed. Moreover, this study set the purpose of developmental security measure for security threats in the aspects of military security.

The purpose of this study is to classify the cities on sustainability assessment score studied in advance using cluster analysis, to present efficient management and policy direction based on analysis of sustainability index in 45 cities of all over Gyeongsangnam and Gyeongsangbuk-do. According to the results of cluster analysis, 45 cities were classed into 4 clusters by "livable-welfare city", "environmental -ecological city", "scientific-technological city", and "industrial-economic city". The livable-welfare cities must keep superior environmental sustainability, promote small and medium sized business on regional characteristic. The environmental-ecological cities have to change agriculture into future environmental industry such as ecotourism, bio-industry and landscape agriculture. The scientific-technological cities are going to need support of government scale such as income enlargement of citizen and stable job security. Finally, the industrial-economic cities must increase environmental management plants and improve quality of life through securing green spaces, maintaining public peace and applying UIS because of low quality of environment and life.

Recently, both wireless communications technology and the performance of small devices have developed exponentially, while the number of services using various types of Internet of Things (IoT) devices has also massively increased in line with the ongoing technological and environmental changes. Furthermore, ever more devices that were previously used in the offline environment-including small-size sensors and CCTV-are being connected to the Internet due to the huge increase in IoT services. However, many IoT devices are not equipped with security functions, and use vulnerable open source software as it is. In addition, conventional network equipment, such as switches and gateways, operates with vulnerabilities, because users tend not to update the equipment on a regular basis. Recently, the simple vulnerability of IoT devices has been exploited through the distributed denial of service (DDoS) from attackers creating a large number of botnets. This paper proposes a system that is capable of identifying Internet-connected devices quickly, analyzing and managing the vulnerability of such devices using Internet-wide scan technology. In addition, the vulnerability analysis rate of the proposed technology was verified through collected banner information. In the future, the company plans to automate and upgrade the proposed system so that it can be used as a technology to prevent cyber attacks.

Purpose: In this study, we proposed a plan to establish and implement a safety and health management system by utilizing corporate resources so that manufacturing companies can effectively respond to the Serious Accident Punishment Act. Methods: We identified critical factors and response strategies necessary for manufacturing companies to respond to the Severe Accident Punishment Act effectively and surveyed employees working at the company regarding their importance and performance. Results: In this study, we presented a method of strategically constructing the response strategies (20) shown in previous studies by matching them with the company's resources (leadership, organization, budget, education, and awareness). In particular, leadership refers to the ability of managers who can prevent serious accidents by carrying out safety and health security obligations to avoid safety and health hazards or risks to employees in the business or workplace that is controlled, operated, and managed. Conclusion: Based on the manager's firm leadership, the system's purpose and direction must be accurately set and sufficiently communicated to members. In addition, for companies to identify and improve risk factors on their own, a Process approach must be established to improve execution by referring to legal standards together with field managers and supervisors.

While commercialization of IoT technologies in the safety management sector is being promoted in terms of industrial safety of large indoor businesses, implementing a system for risk management of small outdoor work sites with frequent site movements is not actively implemented. In this paper, we propose an efficient dynamic workload balancing strategy which combined low-power, wide-bandwidth (LPWA) communication and low-power Bluetooth (BLE) communication technologies to support customized risk management alarm systems for each individual (driver/operator/manager). This study was designed to enable long-term low-power collection and transmission of traffic information in outdoor environment, as well as to implement an integrated real-time safety management system that notifies a whole field worker who does not carry a separate smart device in advance. Performance assessments of the system, including risk alerts to drivers and workers via Bluetooth communication, the speed at which critical text messages are received, and the operation of warning/lighting lamps are all well suited to field application.

In computer forensics investigation, the investigators collect, protect, analyze and interpret massive amount of data which were used in cyber crime. However, due to its huge amount of information, it takes a great deal of time and errors often result even when they use forensics investigation tool in the process. The information visualization techniques will greatly help to improve the information processing ability of human when they deal with the overwhelming amount of data and have to find out significant information in it. The importance of Intrusion Detection System(IDS) among network forensics is being emphasized in computer forensics. In this study, we apply the information visualization techniques which are proposed to be a great help to IDS and carry out the usability test to find out the most effective information visualization techniques for IDS.
