Offices of Education in Korea is planning and implementing the BYOD (bring your own device) policy. In particular, the Seoul Metropolitan Education Office promoted the 'Dibud' (digital buddy) policy. Due to the relative newness of the policy, coupled with opposition from the council, it hasn't been fully implemented. This study focuses on a rare example of a high school that experienced BYOD under the Office of Education-led policy in all three grades. This study adapted key variables from the Technology Acceptance Model (TAM). The regression results showed that both perceived usefulness (PU) and perceived ease of use (PEOU) significantly influenced intention to use Chromebooks and students' perceived learning outcomes. Analysis of the open-ended questionnaires revealed that students perceived positive benefits from using Chromebooks, such as easier data retrieval, improved academic performance, and increased learning productivity. Although the majority of respondents said there were no negative aspects to Chromebooks, negative factors included non-academic use, wireless network inconvenience, and device performance issues. The results of this study can provide data and understanding for future BYOD policies, specifically Chromebooks.

모바일 오피스 확산과 함께 개인 소유의 스마트 폰, 태블릿PC 등을 업무 환경에 사용하는 BYOD 시대에 도래했다. BYOD 등장으로 기업 내부 인프라가 폐쇄적 환경에서 개방적 환경으로 전환했고 언제 어디서나 개인 스마트 기기가 기업 인프라 접근 허용이 가능해 졌다. 모바일 오피스는 휴대성이라는 편리함 이면에 일반 PC환경보다 더 많은 다양한 보안 위협과 취약점이 존재하고 스마트폰 분실 및 정보 유출, 악성코드 등의 위협이 존재하므로 더 높은 수준의 근본적인 보안대책 강구가 필요하다. 본 논문에서는 모바일 개인정보와 BYOD 환경의 모바일 오피스에 대한 보안 위협을 연구하고 모바일 오피스 개인정보 보안 방안을 제시함으로써 모바일 오피스 서비스를 제공하는 기업에게 개인정보 보안 전략을 수립하는 가이드라인을 제공하고자 한다.

In telemedicaine, people can make their health checked at anywhere from temporal and spatial constraints and It's environment can provide continuous health information regardless of the location of customers through PCs and smart phones. In addition, personal health information collected utilizing the BYOD(bring your own device) is the most important factor data security and guaranteed personal privacy because it's directly connected to the individual's health and life. In this paper, we provide a signature of the private key encryption system and method for providing the security of personal health information data collected utilizing the BYOD. Against replay attacks and man-in-the-middle attacks on security issues that are emerging as a smart environmental health was used as the timestamp and signature methods. Proposed method provides encryption overhead, while a communication was lower compared to the pre-encrypted with a mean 1.499mJ 1.212mJ shown by simulation to respond quickly in an emergency situation to be about 59%.

Digital transformation represents one of the main obstacles facing several government, private, and non-profit sectors that help stabilize digital transformation in the Arabic region. One of the helpful ways to improve the level of freedom, productivity, and flexibility among employees to accept the BYOD approach is using their own devices to perform their work both in and outside the workplace. This study focuses to present the differences between the main three economic sectors, which represent the most important pillars of the economy in Saudi Arabia within the Kingdom's Vision 2030. BYOD also has great importance to the stakeholders for raising their awareness by expressing the implications, if the concept of BYOD is widely and correctly adopted. The study uses the diffusion of innovation (DOI) framework and quantitative analysis data to determine the main dimensions and important factors that help increase the awareness of the target audience. The number of participants in this study was 830, and the participants are mixing between the government, private, and non-profit sectors.

Recent studies have indicated that mobile markets harbor applications (apps) that are either malicious or vulnerable, compromising millions of devices. Some studies indicate that 96% of companies' employees have used at least one malicious app. Some app stores do not employ security quality attributes regarding authorization, which is the function of specifying access rights to access control resources. However, well-defined access control policies can prevent mobile apps from being malicious. The problem is that those who oversee app market sites lack the mechanisms necessary to assess mobile app security. Because thousands of apps are constantly being added to or updated on mobile app market sites, these security testing mechanisms must be automated. This paper, therefore, introduces a new mechanism for testing mobile app security, using white-box testing in a way that is compatible with Bring Your Own Device (BYOD) working environments. This framework will benefit end-users, organizations that oversee app markets, and employers who implement the BYOD trend.
