Small and medium-sized enterprises(SMEs) continue to adopt ICT to gain an edge in organizational innovation and competition. This has a management advantage, but it also brings vulnerabilities as to cyber security. Therefore, the purpose of this study is to conduct an exploratory study on the cyber security situation of SMEs. A survey was conducted on Korean SMEs to determine how well they are connected to ICT and how much they are exposed to cyber security threats. The results suggest two things. First, Korean SMEs are well connected to ICT, but there is a gap between the actual adoption and human recognition of its importance. Second, security threats and breaches affect the majority of SMEs, but several problems including costs have not been properly evaluated. The results of this study are expected to help improve the cyber security management system of Korean SMEs.

최근 해킹, 바이러스 등 대한민국을 노린 공격이 증가하고 있다. 이와 마찬가지로 우리 군도 사이버 침해에 대한 노출이 심해지고 있으며 이를 대응하기 위해 국방부는 사이버 안보에 대한 기본절차를 규정하고 지침을 제공하고 있다. 그럼에도 불구하고 육군에서 발간하는 사이버방호작전 분석결과를 보면 침해건수는 점점 증가하고 있다. 이에 대한 문제점들을 개선하고자 사이버 침해 대응을 위해 가장 중요하면서 기본인 사용자 환경에서의 전산보안 점검항목을 재점검하여 안전하고 효율적인 전산보안 점검항목을 제시한다.

Cyber security is an important issue in the field of nuclear engineering because nuclear facilities use digital equipment and digital systems that can lead to serious hazards in the event of an accident. Regulatory agencies worldwide have announced guidelines for cyber security related to nuclear issues, including U.S. NRC Regulatory Guide 5.71. It is important to evaluate cyber security risk in accordance with these regulatory guides. In this study, we propose a cyber security risk evaluation model for nuclear instrumentation and control systems using a Bayesian network and event trees. As it is difficult to perform penetration tests on the systems, the evaluation model can inform research on cyber threats to cyber security systems for nuclear facilities through the use of prior and posterior information and backpropagation calculations. Furthermore, we suggest a methodology for the application of analytical results from the Bayesian network model to an event tree model, which is a probabilistic safety assessment method. The proposed method will provide insight into safety and cyber security risks.

최근 지능정보사회로의 진입으로 인해, 사이버보안 패러다임이 변화하기 시작하였다. 특히 지능정보사회의 상호연결성 등의 증가는 사이버위협으로 인한 피해 범위를 실제 세계까지 확대하였으며, 개개인에 대한 위험이 곧 공공 안전·국가 안보 등의 위기로 연결되고 있다. 특히 디지털 네이티브(Digital Native)세대인 청소년의 경우는 사이버 활동이 많고 보안 및 안전의식이 충분치 않아 사이버위협에 그대로 노출 될 가능성이 더욱 크다. 이에 사이버위협으로부터 개인 스스로를 지키고 사이버활동을 관리할 수 있는 사이버보안 역량 강화가 필요하다. 따라서 본 논문에서는 사이버보안 역량을 강화할 수 있는 사이버보안 정규교육화에 대해 검토하고 대응방안을 제시하고자 한다. 초연결사회 특성에 따른 보안 패러다임 변화와 사이버보안 교육의 필요성에 대해 검토하고 국내외 사이버보안 교육 추진 현황에 대한 분석을 통해 사이버보안 교육 방향 및 기본 체계를 제시하고자 한다. 이에 본 연구는 지능정보사회에서 요구되는 사이버보안역량을 정의하고 사이버보안역량 함양에 관한 주요국 교육체계를 비교·분석하여 사이버보안역량 강화를 위한 정규교육과정을 제안하고자 하였다. 이에 디지털시민으로서의 사이버역량 체계 모델인 C3-Matrix를 반영하여 사이버보안역량 체계를 사이버인식(cyber ethics awareness), 사이버행동(cyber ethics behavior), 사이버보안(cyber security), 사이버안전(cyber safety)로 구성하였다. 그리고 사이버보안역량 체계 기본구성틀에 기반하여 미국, 호주, 일본, 한국에서 수행되는 관련 교육을 비교분석하고 한국 교육과정에 도입되어야 하는 사이버보안역량 교과체계를 제시하였다.

The purpose of this study is to explore how adolescents' psychological characteristics affect their sense of life safety according to gender. To this end, a survey was conducted on male and female high school students in six schools in the C area, and a total of 1,048 data were used for analysis. Differences in major variables according to gender were verified, and the effect of psychological characteristics on living safety awareness was analyzed through hierarchical multiple regression analysis. As a result of the analysis, depression, anxiety, type A characteristics, and the presence or absence of experience in accidents did not significantly affect life safety awareness in the male student group. On the other hand, in the female student group, anxiety and type A characteristics had a significant effect on life safety awareness. Anxiety negatively affects living safety awareness, and type A characteristics have been shown to have a positive effect on living safety awareness. The presence or absence of depression and accident experience did not significantly affect life safety awareness. The results of these studies suggest that gender differences should be considered in education to prevent life safety awareness and that education that reflects the psychological characteristics of adolescents is necessary.

The UAE government has set its sights on creating a smart, electronic-based government system that utilizes AI. The country's collaboration with India aims to bring substantial returns through AI innovation, with a target of over $20 billion in the coming years. To achieve this goal, the UAE launched its AI strategy in 2017, focused on improving performance in key sectors and becoming a leader in AI investment. To ensure public safety as the role of AI in government grows, the country is working on developing integrated cyber security solutions for SCADA systems. A questionnaire-based study was conducted, using the AI IQ Threat Scale to measure the variables in the research model. The sample consisted of 200 individuals from the UAE government, private sector, and academia, and data was collected through online surveys and analyzed using descriptive statistics and structural equation modeling. The results indicate that the AI IQ Threat Scale was effective in measuring the four main attacks and defense applications of AI. Additionally, the study reveals that AI governance and cyber defense have a positive impact on the resilience of AI systems. This study makes a valuable contribution to the UAE government's efforts to remain at the forefront of AI and technology exploitation. The results emphasize the need for appropriate evaluation models to ensure a resilient economy and improved public safety in the face of automation. The findings can inform future AI governance and cyber defense strategies for the UAE and other countries.

This study attempted to explore how the perception of the necessity of safety education for adolescents affects fire safety consciousness and whether personality factors control the relationship. To this end, a survey was conducted at a high school in region C, and data of 1,049 people who agreed to the survey and responded faithfully were used for analysis. Hayes' macro was used to analyze the moderating effect, and as a result of the analysis, adolescents' awareness of the need for safety education increased, and their relationship was significantly regulated by extroversion, openness, and conscientiousness among the five personality factors. A simple regression line analysis was conducted to find out the specific direction, and it was found that the higher the need for safety education in both the group with high extroversion, openness, and conscientiousness, the higher the awareness of safety education. These results suggest that changes in educational methods and contents are needed to raise awareness of the necessity of education in fire safety education and to improve educational motivation, and that it may be helpful to actively utilize students' personality strengths in education.

협업 사이버-물리 시스템(Collaborative Cyber-Physical Systems, CCPS)은 물리 세계와 사이버 세계가 밀접하게 결합하여 공동의 목표를 달성하기 위하여 협업을 수행하는 시스템이다. 한편, 단일 사이버-물리 시스템(Cyber-Physical System)의 경우에는 ISO 26262 또는 IEC 61508과 같은 표준을 따르거나 다양한 위험 분석 기법을 적용함으로써 그 안전을 확보할 수 있다. 그러나 CCPS에서는 협업을 수행중인 한 CPS의 결함으로 인하여 다른 협업 중인 CPS에게 수많은 결함을 발생시키기 때문에 안전의 확보가 매우 어렵다. 본 논문에서는 이러한 CCPS의 위험을 분석하여 안전을 확보하기 위해 복합적인 위험 분석과 위험 분석 산출물 사이의 관계를 기반으로 하는 위험 치명도 매트릭스(Fault Criticality Matrix, FCM)를 제시한다. FCM에서는 결함, 결함의 치명도, 안전 가드와 안전 가드의 발생 확률, 결함의 영향 및 순위를 나열하여 분석한다. 안전 엔지니어는 이를 통해 시스템의 설계 단계에서 각 결함의 치명도와 영향을 분석하고, 설계된 안전 가드를 통해 식별된 고장을 효과적으로 관리하고 제어함으로써 안전한 CPS를 개발할 수 있다. 제시된 방법의 유용성을 확인하기 위해 CCPS의 대표적 예인 군집주행에 대하여 사례 연구를 수행하였다. 본 연구에서 개발된 도구를 사용하여 군집주행 시스템에 FCM을 적용함으로써 상세한 결함 치명도 분석을 수행하였고, 분석 결과는 적합성과 효과성 관점에서 점검되었다. 또한 군집 주행에 대한 시뮬레이션 수행을 통해 FCM을 사용하여 결함 치명도를 분석한 군집주행 시스템이 발견된 모든 결함을 완화시켜 충돌 가능성을 크게 낮추었음을 보였다.
