Purpose: Most of cybersecurity breaches occur in SMEs. As the existing cybersecurity framework and certification system are mainly focused on financial and large companies, it is difficult for SMEs to utilize it due to lack of cybersecurity budget and manpower. So it is necessary to come up with measures to allow SMEs to voluntarily manage cyber risks. Method: After reviewing Cybersecurity market, cybersecurity items of financial institutions, cybersecurity framework comparison and cybersecurity incidents reported in the media, the criticality of cybersecurity items was analyzed through AHP analysis. And cybersecurity items of non-life insurers were also investigated and made a comparison between them. Result: Cyber risk management methods for SMEs were proposed for 20 major causes of cyber accidents. Conclusion: We hope that the cybersecurity risk assessment measures of SMEs in Korea will help them assess their risks when they sign up for cyber insurance, and that cyber risk assessment also needs to be linked to ERM standardization.

Information Security Incidents that have recently happen rapidly spread and the scale of that incidents' damage is large. In addition, as it proceeds to the era of converged industry in the future environment and the virtual cyber world expands to the physical world, new types of security threats have occurred. Now, it is time to supply security professionals who have a multi-dimensional security capabilities that can manage the strategies of technological security and physical security from the management point of view, rather than the ones who primarily focus on the traditional technologic-centered strategies to solve new types of security threats. In conclusion, in this paper we try to produce the curriculum of information security featured in the occupational classification system and analyze the subjects that are additionally required for those who move to other occupations to cultivate security professionals who suited to the converged-industrial environment. It is expected that multi-dimensional security professionals who suited to the converged-industrial environment will be cultivated by harmoniously integrating information security subjects from technological and business/managerial perspectives, and education training courses will be developed that effectively provide core knowledges per occupational classification when people moves to other occupations in the areas of information security.

Despite the recent growth in size and frequency of damages caused by illegal information breaches, current business counter-measures and precautionary systems are greatly limited. Some major companies have developed Information Security Management Systems (ISMS) to safeguard their vital information; however, such measures are largely based on the ISO27001 and lacks in many aspects to grasp the holistic corporate security level and reinforce precautionary measures. The information protection level evaluation model introduced in this paper is a pragmatic evaluative tool that can be utilized to devise effective corporate information security precautionary measures and countermeasures, based on the BSC (Balanced ScoreCard) method for an actual and realistic corporate information security level evaluation possible.

Electronic financial accidents are constantly happening and these accidents are taking place by a combination of several causes such as technique, human, and structure. Among electronic financial accidents, personal information disclosure is most frequently happening and becomes big problems, because secondary damage like voice phishing causes great loss to society. This research model is that financial information security compliance affects the crisis response of financial institutions and financial authorities and these crisis responses affect financial information security trust. Research target is people who experienced the disclosure of their own financial information. For empirical verification, survey questionnaires were distributed and total 103 questionnaires were collected and analyzed. As results of data analysis, all hypotheses were accepted. First, financial information security compliance influenced the crisis response of financial institutions and authorities. Second, the crisis response of financial institutions and authorities affect financial information security trust. Third, at the moderating effect analysis, the importance of personal financial information moderated the effect of the crisis response of financial institutions on financial information security trust. And the disclosure level of personal financial information moderated the effect of the crisis response of financial authorities on financial information security trust.

An era of smart manufacturing is coming through the rapid development of information and communication technology. As a result, many companies have begun to utilize a variety of hardware and software for the efficient business of the manufacturing process. At this time, the hardware and software used are supplied through manufacturing and distribution processes. These supply processes are exposed to a variety of security threats. As the recent cases of supply chain attacks have increased, foreign countries are establishing supply chain management systems and managing supply chain risks. In Korea, on the other hand, there was research on supply chain risk management in some fields. In this paper, we emphasizes the necessity of supply chain risk management through supply chain attack cases. In addition, we analyze trends of foreign supply chain management system and explains the necessity of domestic supply chain security strategy.

미래 정보사회로 의미가 확대된 유비쿼터스 환경은 글로벌 컴퓨팅 환경에 기반한 유비쿼터스 인프라에서의 최적 보안 서비스 제공을 위한 지속적인 정보보호 기술이 요구되고 있다. 이와 같이 보안 서비스는 사용자에게 유비쿼터스 사회에서의 안전성, 신뢰성, 건전성을 제공하기 위한 다양한 수단을 포괄하는 개념으로, 개인의 프라이버시 침해 및 컨텍스트의 무분별한 사용이라는 문제점에 대응할 수 있어야 한다. 현재의 ID/Password를 사용한 인증 단계에서 발생되는 여러 문제들에 대한 대응 방안으로 OTP(One Time Password)가 부각되고 있다. OTP는 다양한 어플리케이션으로의 적용 및 유연한 사용자 권한 설정이 가능한 장점을 통해 다른 사용자 인증 방식에 비해 유비쿼터스 환경으로의 효율적인 적용이 가능하다. 하지만 OTP에 대한 인식의 부족 및 사용자 인증에 대한 중요성 인지 미흡으로 인하여 OTP 활용을 위한 시스템과 구조 연구가 부족하고, 제한적인 서비스에 OTP가 활용되고 있다. 본 논문에서는 사용자를 위한 보안 서비스를 제공하고자 유비쿼터스 환경에서의 보안 요소 강화를 위한 OTP의 보안 요구사항을 분석하고, OTP를 이용한 다양한 적응 방안을 고려한다. 이와 같은 연구를 통해 OTP의 효율적 관리 방안과 다양한 서비스 및 환경에서의 적용 방안 연구를 통하여, 기존 인증 방식보다 보안성이 강화된 인증 체계의 구현과 다양한 보안 서비스 제공이 가능할 것으로 기대 된다.
