In this paper we applied our previously developed assessment framework to the data collected from an internet security readiness survey targeted at households. We used the assessment framework to compute an Internet Security Readiness index for each household, which was in turn derived from Internet Security Readiness capital, skill, and actual uptake/use of infrastructure indices. We then examined the relationships among overall Internet Security Readiness, and the capital, skill, and actual uptake/use of infrastructure related to Internet Security Readiness. In addition, we explored the influence of Internet usage level and experience on Internet Security Readiness.

Today, phishing attacks represent one of the biggest security threats targeting users of the digital world. They consist of an attempt to steal sensitive information, such as a user's identity or credit and debit card details, using various methods that include fake emails, fake websites, and fake social media messages. Protecting the user's security and privacy therefore becomes complex, especially when those users are children. Currently, children are participating in Internet activity more frequently than ever before. This activity includes, for example, online gaming, communication, and schoolwork. However, children tend to have a less well-developed knowledge of privacy and security concepts, compared to adults. Consequently, they often become victims of cybercrime. In this paper, the effects of security awareness on users who are children are investigated, looking at their ability to detect phishing attacks in social media. In this approach, two Experiments were conducted to evaluate the effects of security awareness on WhatsApp application users in their daily communication. The results of the Experiments revealed that phishing awareness training has a significant positive effect on the ability of children using WhatsApp to identify phishing messages and thereby avoid attacks.

Many organizations are threatened by numerous information security attacks which are resulting in information security incidents. To prevent information security incidents, organizations invest on various information security measures like information security products, monitoring services and security training and educations. However they do not have enough knowledge about measurable utilities of information security investments. Since there is little studies empirically examining the effect of information security investments, this research aims to find out utilities of information security investment. We especially focuse on information security service investments. This study examined the data from the survey on information security for business sector which was conducted by Korean information & security agency. We utilized negative binomial regression model, which is a suitable model for over-dispersed count data. We found out that an investment on information security education and vulnerability testing have direct impact on reducing information security incidents. This research academically contributed to shed light on the utility of information security investments on reducing information security incidents. This research practically contributed to providing information security investment guideline for organizations which want to reduce information security incidents efficiently.

Organizations that make widely use of information technologies can be more efficient. But, the dependence of information technologies leads to an increase in threat of security. This is the reason why organizations are investing in security risk management (SRM) which is designed to protect of information assets. Noting a lack of empirical research in SRM, we investigate the key factors having a direct effect on performance of SRM. Particularly, this study focused on identifying factors influencing awareness of SRM and Intention to develop SRM in Organization. Based on relevant literature review, six motivating factors, including Behavior for Security Management, Compliance with Security Policy, perceived Benefits, Perceived Sacrifice, Social Pressure, Experience of Security Risks, were initially identified. The results indicated that most perception factors were positively related to Organization's intention to develop SRM and awareness of SRM, which then had positive impact on performance of SRM. But Perceived Sacrifice was not significantly related to two variables which is Organization's intention to develop SRM and awareness of SRM.

PKI(Public Key Infrastructure)-based information certification technology has some limitations to be universally applied to mobile banking services, using smart phones, since PKI is dependent on the specific kind of web browser, Internet Explorer. OTP(One Time Password) is considered to be a substitute or complementary service of PKI, but it still shows low acceptance rate. Therefore, in this research, we analyze why OTP has not been very popular, and provide useful implications of making OTP more extensively and frequently used in the mobile environment. Perceived security of OTP was set as a higher-order construct of integrity, confidentiality, authentication, and non-repudiation. Research findings show that security awareness and perceived security of OTP is positively associated, and the relationship between perceived security and trust on OTP is statistically significant. Also, trust is positively related to intention to use OTP continuously.

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.

The importance of information security is increasing, and various efforts are being made to improve users' information security behaviors. Among these various efforts, information security education is mainly aimed at providing users with information security knowledge and improving information security awareness. This study classified the types of information security education into offline and online to examine the effects of each education method on attitudes toward information security (perceived severity, vulnerability, self-efficacy and response-efficacy) and information security behaviors. A survey was conducted for users with information security education experiences. The results obtained by comparing the differences in the path coefficients of personal information security behaviors according to information security education experiences showed that security behaviors were more significant in the online experience group than the offline group. In addition, gender differences were analyzed, and it was found that females had a greater impact on information security attitudes than males. This study also found that among Internet users with online information security education experience, females tend to have more information security behavior than males, but there were contrasting results among users with offline information security education experiences. The results of this study finally address the necessity of reflecting users' personalities in the systematic design of information security education in the future. Furthermore, the results of this study support the need for an appropriate education system that sufficiently understands education types to maximize the effects of information security education.
