In the complex virtual environment of cyberspace, comprised of digital and communication networks, ensuring the security of information is being recognized as an ongoing challenge. The importance of 'Cyber Situation Awareness (CSA)' is being emphasized in response to this. CSA is understood as a vital capability to identify, understand, and respond to various cyber threats and is positioned at the heart of cyber security strategies from a defensive perspective. Critical industries such as finance, healthcare, manufacturing, telecommunications, transportation, and energy can be subjected to not just economic and societal losses from cyber threats but, in severe cases, national losses. Consequently, the importance of CSA is being accentuated and research activities are being vigorously undertaken. A systematic five-step approach to CSA is introduced against this backdrop, and a deep analysis of recent research trends, techniques, challenges, and future directions since 2019 is provided. The approach encompasses current situation and identification awareness, the impact of attacks and vulnerability assessment, the evolution of situations and tracking of actor behaviors, root cause and forensic analysis, and future scenarios and threat predictions. Through this survey, readers will be deepened in their understanding of the fundamental importance and practical applications of CSA, and their insights into research and applications in this field will be enhanced. This survey is expected to serve as a useful guide and reference for researchers and experts particularly interested in CSA research and applications.

This study measured college students' levels of satisfaction with their cyber learning through an online survey of students who had taken one or more cyber learning before. 500 returned and usable questionnaires were analyzed and SPSS WIN 12.0 was used for the descriptive statistics, t-test, factor analysis and analysis of covariance structures. The results are as follows; First, college students were very interested in their cyber learning. Their decision to take the cyber learning was initiated more by emotional motives (m=3.13) than by rational motives (m=3.35). Second, the consumers' expectations for the cyber learning were divided into the 'Expectation for service quality' and the 'Expectation for economy,' and their 'Expectation for economy'(m=4.02) was higher than their 'Expectations for service quality'(m=3.60). Third, the consumers' expectations for the cyber learning and the results of the cyber learning were analyzed, and a discrepancy between these two were also analyzed. The analysis of discrepancy between the two showed that the average of the results was lower than that of the expectations, which means that the cyber learning did not meet the consumers' expectations in every aspect, However, the average satisfaction level was 3.20, which means consumers were satisfied with the cyber learning overall. Fourth, causes of dissatisfaction with the cyber learning were divided into internal factors due to personal matters and external factors due to classes and other factors. It was found that dissatisfaction due to internal factors was greater than that due to external factors. Lastly, the factors affecting satisfaction/dissatisfaction with the cyber learning and willingness to use it again were analyzed. The results showed that the motive for its use affected the formation of expectation but it did not affect the results. Satisfaction with the cyber learning affected the willingness to use it again positively. However, the effect of dissatisfaction on the willingness to use it again was not statistically significant.

사이버 공간에서의 폭력이 최근 그 정도를 더해가고 있으며 이는 피해자에게 극심한 정신적 고통을 초래할 뿐만 아니라 건전한 사이버문화를 저해하고 있다. 이러한 사이버폭력의 특징 및 실태를 알아보고 그에 대한 대책을 제시해 보고자 했다. 사이버범죄는 비대면성, 익명성, 무제약성, 증거확보의 어려움 등을 특징으로 하며, 이러한 사이버범죄 중 사이버폭력은 사이버모욕, 사이버명예훼손, 사이버스토킹, 사이버음란물유포 등의 형태로 나타나는데 이에 대한 실질적인 대책이 미흡한 것이 현실이다. 이에 대한 대책으로 실정법상의 사이버모욕죄의 신설, 인터넷실명제의 도입, ISP의 책임의식 강화 및 형사처벌을 위한 관련입법이 필요하며, 보다 근본적인 대책으로 네티즌의 자정노력과 피해예방을 위한 체계적인 교육 및 홍보가 이루어져야 할 것이다.

Tension and self-control are explanatory factors in adolescent delinquency, and internet addiction and anonymity are regarded as factors underlying cyber deviation. The aim of this study was to investigate the interrelationships between these factors and cyber deviation. Participants were 485 middle and high school students in the Jeonbuk region. The results showed that tension and self-control were predictors of cyber deviation and that internet addiction was a mediating variable for both the predictors. Anonymity was found to have a mediating role, but only in respect of the tension-cyber deviation pathway. These findings suggested a number of implications. Firstly, the educational programs on cyber deviation should be different from the existing deviation prevention programs. Secondly, measures to prevent internet addiction are needed for the effective prevention of cyber deviation. Lastly, the finding of a relationship between anonymity and cyber deviation indicates the need to adopt a long-term perspective drawing on values education techniques to develop a code of cyber space ethics for "netizens".

The growing trend of cyber risk has put forward the importance of cyber risk management. Cyber risk is defined as an accidental or intentional risk related to information and technology assets. Although cyber risk is a subset of operational risk, it is reported to be handled differently from operational risk due to its different features of the loss distribution. In this study, we aim to detect the characteristics of cyber loss and find a suitable model by measuring value at risk (VaR). We use the loss distribution approach (LDA) and the time series model to describe cyber losses of financial and non-financial business sectors, provided in SAS^® OpRisk Global Data. Peaks over threshold (POT) method is also incorporated to improve the risk measurement. For the financial sector, the LDA and GARCH model with POT perform better than those without POT, respectively. The same result is obtained for the non-financial sector, although the differences are not significant. We also build a two-dimensional model reflecting the dependence structure between financial and non-financial sectors through a bivariate copula and check the model adequacy through VaR.
