모바일 클라우드 서비스는 사용자가 모바일 단말에 자원을 가지고 있지 않더라도 인터넷을 통해 외부의 다양한 IT 자원을 제공하는 서비스로서 모바일 단말이 가지는 성능적 한계를 극복시킬 수 있다는 장점과 함께 이용자 수가 증가하고 있다. 그러나 클라우드 컴퓨팅 환경에 존재하는 개인 및 기업의 정보 유출과 같은 문제들은 모바일 클라우드 컴퓨팅 환경에도 그대로 상속되기 때문에 이러한 문제에 대응하기 위해서는 모바일 클라우드 컴퓨팅 환경에서 정보유출을 탐지할 수 있는 이상행위 탐지 알고리즘이 마련되어야 한다. 여기서 이상행위란, 모바일 클라우드 자원에 접근하는 방법에 있어 기존에 인지하고 있던 정상적인 행위에서 벗어나는 행위를 의미하며 이상행위로 판단되는 상황이 발생되는 경우, 이를 정보유출이 발생할 수 있는 상황으로 인지함으로써 적절한 대응을 할 수 있게 된다. 따라서 본 논문에서는 모바일 클라우드 자원의 정보유출을 방지하기 위한 목적으로 자원 접근에 대한 이상행위 탐지 알고리즘 개발 모델을 제시한다. 이상행위 탐지 알고리즘을 개발하고 이를 검증하기 위해서는 이상행위를 일으키는 공격 모델 및 대응 모델이 개발되어야 한다. 따라서 본 논문에서는 인증 및 권한관리의 취약점을 이용하여 위협을 일으키는 공격 모델을 개발하는 방법을 제시하고, 사용자의 접속환경 및 클라우드 자원의 정보 흐름을 분석함으로써 이상행위를 탐지하는 알고리즘을 제시한다.

The purpose of this study is to identify the determinants of planned behavior of adolescent, toward information security and cyber crime prevention. A survey methodology was used to investigate a proposed model of influence, and regression analysis was used to analyze the results. The hypothesized model was largely supported by this analysis, and the overall results indicate that the intention to actively participate in information security and cyber crime prevention is mostly influenced by the fear for cyber crime and the perceived usefulness of information security and cyber crime prevention activity. In addition, it was found that the perceived easy of use for information-security related ICT skill, fear for cyber crime, and social norm for information security influence the level of usefulness, but that the prior experience with information leaking was statistically insignificant factor to the level of usefulness and fear for crime. Useful suggestions for promoting information security and cyber crime prevention are also provided.

This study is a descriptive research study conducted to understand the effects of hospital nurses' COVID-19 risk perception, media dependence, government trust, resilience, and Socio-psychological stress on COVID-19 prevention behavior. Data were collected from 200 nurses at university hospitals, and the collected data were analyzed using descriptive statistics, t-test, Pearson's correlation analysis, ANOVA, and multiple regression analysis using the SPSS 24.0 program. The average age of the subjects was 29.8 years old, the hospital experience was 6.6 years, and the prevention of COVID-19 was high with 4.3 points. COVID-19 prevention behavior showed positive correlation with COVID-19 risk perception, resilience, and media dependence and negative correlation with socio-psychological stress. Factors influencing COVID-19 prevention behavior were COVID-19 risk perception, resilience, socio-psychological stress, and media dependence. To ensure that hospital nurses' COVID-19 prevention behaviors can be continued, it is necessary to appropriately manage COVID-19 risk perception and media dependence, and to develop and apply an intervention program to strengthen resilience and reduce socio-psychological stress.

Recently, the incidence rate of malicious codes is over tens of thousands of cases, and it is known that it is almost impossible to detect/respond all of them. This study proposes a method for detecting multiple behavior patterns based on a graph database as a new method for dealing with malicious codes. Traditional dynamic analysis techniques and has applied a method to design and analyze graphs of representative associations malware pattern(process, PE, registry, etc.), another new graph model. As a result of the pattern verification, it was confirmed that the behavior of the basic malicious pattern was detected and the variant attack behavior(at least 5 steps), which was difficult to analyze in the past. In addition, as a result of the performance analysis, it was confirmed that the performance was improved by about 9.84 times or more compared to the relational database for complex patterns of 5 or more steps.
