Interactions in healthcare, by necessity, involve sharing sensitive information to achieve high-quality patient outcomes. Therefore, sensitive data must be carefully protected. This article explores existing privacy and security research conducted in the context of healthcare organizations. We conducted a systematic literature review of N =1,553 articles that examine the security and privacy of healthcare data and focus on 80 articles addressing human factors. Key findings show that much of the healthcare security and privacy research is focused on technology (44.11%, 712 articles), with a lack of emphasis on the human element (4.96%, 80 articles). In the subset of user studies, we find that patients and the general public express concerns about privacy and security with technologies like electronic health records (EHRs). Furthermore, our analysis shows that healthcare professionals often have low awareness of risks related to data security. Additionally, our analysis revealed that most research focuses narrowly on large hospitals, neglecting private practices and the unique challenges they face. We conclude by identifying research gaps and providing potential solutions to enable robust data security for sensitive patient data.

The World Wide Web (www) consists of the surface web, deep web, and Dark Web, depending on the content shared and the access to these network layers. Dark Web consists of the Dark Net overlay of networks that can be accessed through specific software and authorization schema. Dark Net has become a growing community where users focus on keeping their identities, personal information, and locations secret due to the diverse population base and well-known cyber threats. Furthermore, not much is known of Dark Net from the user perspective, where often there is a misunderstanding of the usage strategies. To understand this further, we conducted a systematic analysis of research relating to Dark Net privacy and security on $N=200$ academic papers, where we also explored the user side. An evaluation of secure end-user experience on the Dark Net establishes the motives of account initialization in overlaid networks such as Tor. This work delves into the evolution of Dark Net intelligence for improved cybercrime strategies across jurisdictions. The evaluation of the developing network infrastructure of the Dark Net raises meaningful questions on how to resolve the issue of increasing criminal activity on the Dark Web. We further examine the security features afforded to users, motives, and anonymity revocation. We also evaluate more closely nine user-study-focused papers revealing the importance of conducting more research in this area. Our detailed systematic review of Dark Net security clearly shows the apparent research gaps, especially in the user-focused studies emphasized in the paper.

COVID-19 has created a dramatic paradigm shift in education methods, which forced schools and universities to abandon the usual in-person education in favor of online education modules. Such a shift has extended the time and use of internet communication technologies (ICTs) by most, making online education platforms primary cyberattack targets. In this context, this study aims to explore parents, educators, and other caregivers' concerns about online education and the cybersecurity of their children and students. Thus, we conducted a survey-based study with 983 participants recruited through popular crowdsourcing platforms: MTurk and Prolific. Our results indicate a lack of technical support following cyber safety that the students received with the sudden transition to online education. Over 31% of our participants claimed that they never or rarely receive any communication related to cyber safety from the students' educational institutions. Additionally, our analysis shows that the student support structure needs to be trained and informed on the threats faced by children online and on the ways to mitigate these threats. Finally, we find a statistically significant difference between parents, educators, and other caregivers regarding their perceptions of children's online privacy and cyber safety. We conclude this work by providing actionable recommendations to promote privacy-preserving and digitally secure online education.
