In this paper, we present secondary research on recommended cybersecurity practices for social media users from the user’s point of view. Through following a structured methodological approach of the systematic literature review presented, aspects related to cyber threats, cyber awareness, and cyber behavior in internet and social media use are considered in the study. The study presented finds that there are many cyber threats existing within the social media platform, such as loss of productivity, cyber bullying, cyber stalking, identity theft, social information overload, inconsistent personal branding, personal reputation damage, data breach, malicious software, service interruptions, hacks, and unauthorized access to social media accounts. Among other findings, the study also reveals that demographic factors, for example age, gender, and education level, may not necessarily be influential factors affecting the cyber awareness of the internet users.

The emergence of Cloud Computing and consequential changes to infrastructure and work practices leaves little doubt that most computing platforms will be impacted by increased security concerns. Therefore, within the context of a security framework, issues surrounding the exploitation of hard or soft network elements in a Cloud architecture need to be acknowledged. To be applicable to any Cloud architecture, such a framework needs to play a role within the operational context of Cloud Computing. The framework is presented as a taxonomy of security threats specific to Cloud Computing environments.

This paper presents a survey on energy harvesting (EH) wireless communication networks focusing on channel capacity, transmission schemes, and power optimization. While many network researchers focus on energy management policies addressing the intermittency and randomness of the EH processes, but the channel capacity, and transmission power optimization have not been fully explored yet. In this paper, we provide a review and analysis of channel capacity, offline and online transmission schemes, and power optimization from an information theory perspective. By reviewing and analyzing wireless networking literature, we found that EH is a technologically feasible and economically viable paradigm for cost-effectiveness in the design and deployment of next-generation wireless networks. Finally, we identify open research problems and future research directions in the emerging field of EH wireless networks. We expect this study to stimulate more research endeavors to build energy-efficient scalable next-generation wireless network systems.
