사이버 위협이 고도화, 지능화되면서 사이버보안 사고로 비롯한 유무형 손실이 점차 증가추세에 있으며, 이러한 피해를 최소화 하기 위해 사이버보안에 대한 필요성이 증대되고 있다. 기업에서는 각종 규제와 법률에 근거하여, 또는 신뢰할 수 있는 서비스를 고객에게 제공하기 위해서 보안 솔루션, 보안 서비스, 보안 컨설팅 등 다양한 방면에서 보안에 대한 투자를 늘리고 있다. 기업의 보안에 대해 투자는 비용과 효과를 분석하여야 효율적이고 효율적인 투자일 것이나, 아직은 이에 적합한 방안이 제시되지 않고 있다. 따라서 본 연구는 사이버보안 환경에 적합한 비용/효과 분석 방안으로 CMU SQUARE 팀의 비용효과분석 프레임워크를 선택하였고, SQUARE의 프레임워크를 기반으로 사이버보안 투자에 적합한 비용/효과 측정 방안을 제시하였다. 특히 기존의 금전적 효과에만 치중되어 연구가 부족했던 정성적 효과를 고려하여, 사이버보안 투자에서 발생되는 효과를 종합적으로 측정할 수 있도록 한다. 본 연구의 결과는 사이버보안과 관련된 투자의 비용/효과를 산출함으로써 기업의 보안 투자 방안 추진의 기준이 될 것이다.

오늘날 정보화의 급진전에 따른 PC의 광범위한 보급과 네트워크의 확산은 컴퓨터 바이러 스와 관련된 역기능을 심각하게 형성하는 계기가 되었다. 더욱이 컴퓨터 바이러스 개발기술의 발전에 따라 신종 바이러스가 더욱 기술적으로 정교해지고, 다양한 변종이 출현함에 따라 바이러스 대응 소프트웨어를 설치하는 것만으로는 효과적으로 대처할 수 없다는 문제가 제 제기 되었다. 조작의 정보보안을 위해 전반적인 관리적 차원에서 바이러스를 효과적으로 통제할 수 있도록 여러 가지 요인들을 고려해야 한다. 이를 위해 조직의 정보자원의 관리 방향을 제시하고 있는 보안정책이 강조되어야 함은 물론이며, 전체적인 관점에서 정보시스템에 대한 보안을 강화하기 위하여 정보 기술에 대한 부적절한 활용을 통제하고, 사용자 측면에서 감염 확산의 차단 및 재발을 효과적으로 억제할 수 있어야 한다. 이에 따라 본 연구에서는 직접적인 컴퓨터 바이러스 통제를 위해 관리적 측면에서 요인들을 강조하고, 사용자의 시스템 관련 지식 및 인지적 특성 등의 개인적 특성을 반영하여 보안효과를 평가할 수 있도록 연구모형을 구성하였다. 구조방정식 모형에 의한 실증분석 결과에 의하면 조직내 보안정책이 바이러스 통제의 수준에 영향을 미치며, 사용자의 컴퓨터 바이러스 관련 보안인식을 향상시킬 수 있는 것으로 나타났다. 또한 보안통제는 보안효과에 긍정적인 영향을 미치지만 사용자의 정보보안 관련 특성은 보안효과에 영향을 미치지는 않는 것으로 분석되었다.

This study analyzed the multi-mediating effects of information security, personal information infringement, personal experience, and information security intention in the relationship between personal information protection and information security attitude. For this purpose, a survey was conducted on 221 students from G University. First, information security, personal information infringement, and information security awareness had a simple mediating effect. Second, information security, personal information infringement, personal experience, and information security consciousness had parallel multi- mediation effects. Third, personal information infringement and information security awareness had a simple mediating effect in the parallel multiple mediation state. Fourth, information security had a simple mediating effect, but it was found that there was no simple mediating effect in the parallel multiple mediation state. This study is meaningful in that it empirically compared the simple and multi-mediation effects.

Information securiry is considered important due to the side effect generated from the expansion of information system and rapid increase of the use of internet. Nevertheless, we are getting unconscious of the importance of information security. The purpose of this research is to empirically analyze that the effects of security policies, security awareness and individual characteristics on password security effectiveness. Based on the analysis of research model using structural equation modeling technique, security policies were influencing individual characteristics and improving user's security awareness. Also individual characteristics and security awareness had positive impact on security effectiveness.

This study empirically verified whether there is a dual mediating effect of individual optimistic bias and information security intention in the relationship between information security attitude and information security behavior of social welfare college students. The subjects were 295 college students majoring in social welfare. Spss Process macro was used for analysis. As a result. first there was a significant positive correlation between the variables. Second in the relationship between information security attitude and information security behavior, individual optimistic bias and information security intent each had a simple mediating effect. Third when an individual's optimistic bias and information security intent were simultaneously input, each had a simple mediating effect. Fourth there was a double mediating effect between individual optimistic bias and information security intent. This study provided basic data for the expansion of information security model and information security education of social welfare students.

The information security policy is one of the most important tools for organization to manage the implementation and ensure the organizational security. However, we do not have metrics for measuring its effectiveness. The ultimate purpose of this study is to develop the measures of information security policy effectiveness. To do this, this study review data quality and information quality literatures and investigate appropriate subfactors for information security policy. Rooted in these concepts, we suggest accuracy, completeness, interpretability, and relevance from content aspect and understandability, concise representation, and amount from form aspect as factors for information security policy effectiveness.

In the past, organizations tended to focus on physical and technical aspects of managing corporate's information security (IS), rather than the aspect of human resources related to IS. Recently, increasing security incidents caused by organization members raise the issue of how to improve employees' compliance with security policies. This study conducted a field experiment to examine the effect of security awareness training and technical security services on employee's security behaviors. In Study 1, the number of spam opening cases were measured right after the IS training and re-measured three months later. In Study 2, a spam warning message was provided and then the number of employees' spam opening cases were counted to find out the effect of security services. It was found that both the IS training and the technical IS service were effective; they significantly decreased spam opening rates. However, the training effect did not last longer than three months. These findings suggest that organizations need to consider providing regular training programs and supplementary technical services to improve employees' compliance with security policies.

It is important to secure patient healthcare information in medical institutions. Education can enhance healthcare information security practice. The purpose of this study is to investigate the effect size of the correlation between healthcare information security education and healthcare information security practice in medical institutions. Systematic Review and Meta-Analysis were used for this study. Data were collected from January 1, 2010 to July 31, 2019 through DBpia, RISS, NDSL. Four studies were eligible for inclusion in the analysis. Data were analyzed with R. The results of the Meta-Analysis demonstrated statistically significant large effect size of correlation with education and practice. Based on the results of this study, we will be able to understand the importance of healthcare information security education in medical institutions and use them as a basis for developing healthcare information security education programs.

In order to ensure that all firms are cyber-secure, many governments have started to enforce the implementation of various security measures on firms. Prior to the implementation, however, it is vague whether government enforced security measures will be effective for mitigating cyber-security risks. By applying a method for estimating the effectiveness of a mandatory seatbelt law in reducing fatalities from motor vehicle accidents, this study develops an ex ante evaluation method that can approximate the effectiveness of a government enforced security measure in reducing country-wide or industry-wide cyber-security risks. Using data obtained from the Korean Internet and Security Agency, this study then explores how to employ the developed method to assess the effectiveness of a specific security measure in mitigating cyber-security risks, if enforced by the government, and compares the effectiveness of various security measures. The comparison shows that compulsory security training has the highest effectiveness.
