In this paper, we designed the security management system based on IEC 62351-7 in the Smart Grid environment. The scope of IEC 62351-7 focuses on network and system management (NSM) of the information infrastructure as well as end-to-end security through abstract NSM data objects for the power system operational environment. However, it does not exist that security management system based on IEC 62351-7 manages the security of the power system in the Smart Grid environment, because power equipment or SNMP agents providing NSM data do not exist yet. Therefore, we implemented the security management system to manage the information infrastructure as reliably as the power system infrastructure is managed. We expect that this system can perform the security management of IEC 61850 based digital substation and can be a prototype of the security system for the Smart Grid in the future.

As social interest in the metaverse increases, various metaverse platforms and services are appearing, and various security issues are emerging accordingly. In particular, since all activities are performed in a variety of virtual spaces, and the metaverse utilizes sensing data using various hardware devices, more information is accumulated than other Internet services, and more damage can occur if information security is not guaranteed. Therefore, in this paper, we propose a metaverse security model that considers the major issues mentioned in previous papers and the necessary evaluation factors for the security functions required in the metaverse platform. As a result of performing the performance evaluation of the proposed model and the existing attribute information collection model, the proposed model can provide security functions such as anonymity and source authentication, which were not provided by the existing models.

Methods that industrial spies use to smuggle core technology out are becoming more intelligent, technological, and complex, thus resulting in more serious damages. In particular, defense industries in which involve national core technology as well as institutions including labor force are industries that are in a greater need of the convergence security. Defense Industry develops, experiments, and produces defense security supplies for national security protection. Defense industry involves a number of security elements such as military secret, industrial secret, core technology labor force, defense industry supply, critical national facility, and information communication system. Defense industry security is a complex of military security and industrial security which is convergence security that integrates all security elements of defense industry. Therefore, defense industry security is a typical ideal model for convergence security. Research on defense industry security is relatively insufficient compared to research of security in other industrial fields. In order to prevent core technology of denfese industry from leaking and to protect technical professionals and institutions, research and action on defense industry security from convergence security perspective are therefore essential at this point of time.

As the society turns into more of an information an technology centric society, the importance of information security is being increased these days. Recently, as the number of leaking accidents of personal information and valuable industrial technology is on the rise, every field of industry endeavors to come up with a security solution. In particular, since defense industry is a field where it establishes national defense power that is essential of national security, it requires higher standards of security solutions than any other ordinary fields of industry. According to Defense Industry Security Work Instructions, defense industry firms from security organizations and employ a security worker corresponding to the firm's scale and conditions. In an environment where essential information and technology are stored and managed in information and communication system or storing media, the duty and role of IT security workers are crucial. However, there is a shortage of systematic analysis on the work of IT security workers and development of curriculum to enhance their professionalism. Thus DACUM process, a job analysis technique, was used to identify IT Security workers' duties and responsibilities and verify the validity and credibility of the deducted results from the survey. The findings of this study will help in development of IT security duty in defense industry and can be used as baseline data for the development of curriculum and amendments of related regulations.

The increasing integration of intelligent information technologies within organizational systems has amplified the risk to personal information security. This escalation, in turn, has fueled growing apprehension about an organization's capabilities in safeguarding user data. While Internet users adopt a multifaceted approach in assessing a company's information security, existing research on the multiple dimensions of information security is decidedly sparse. Moreover, there is a conspicuous gap in investigations exploring whether users' evaluations of organizational information security differ across industry types. With an aim to bridge these gaps, our study strives to identify which information security attributes users perceive as most critical and to delve deeper into potential variations in these attributes across different industry sectors. To this end, we conducted a structured survey involving 498 users and utilized the analytic hierarchy process (AHP) to determine the relative significance of various information security attributes. Our results indicate that users place the greatest importance on the technological dimension of information security, followed closely by transparency. In the technological arena, banks and domestic portal providers earned high ratings, while for transparency, banks and governmental agencies stood out. Contrarily, social media providers received the lowest evaluations in both domains. By introducing a multidimensional model of information security attributes and highlighting the relative importance of each in the realm of information security research, this study provides a significant theoretical contribution. Moreover, the practical implications are noteworthy: our findings serve as a foundational resource for Internet service companies to discern the security attributes that demand their attention, thereby facilitating an enhancement of their information security measures.

In the modern society based on information and communication, which is exposed to the risks of a lot of information security breaches, corporate information assets may be an economical scale in a country. Most of damages derived from corporate technological information leak often occur in small and medium corporations. Although many information security managers in corporations have focused on certification systems such as information security management system, small and medium corporations are poorly aware of the information security, and their environments surrounding it should be also improved. In addition, it is difficult to expect spontaneous participations in it, since the sustainable information security management systems are often not forced to be certified. Thus, the purpose of this study is to examine plans to improve small and medium corporations' technological protections by using some component of the information security management system. On the basis of this examination, it also attempts to discuss some methods for effective and efficient information security in the small and medium corporations' technological protections.
