In recent years, significant progress has been observed in cloud computing. As the number of companies using the cloud increases, so does the need to protect user data. Today, the major challenges facing cloud computing include the security, protection, and processing of data belonging to users. This study aims to investigate security issues and identify appropriate security techniques in the world of cloud computing. Also, the identification of security challenges that may arise in the field of cloud computing in the future has been evaluated. In this research, we used two different research methods: systematic literature review (SLR), and survey and interview with different security experts who work in the field of cloud computing. All the security challenges, most compromised attributes, and identified mitigation techniques from both SLR and survey were presented and discussed.

Social media are an important medium for exchanging information acting a vital role in today’s living edge. Social media are computer-mediated communication (CMC) technologies that facilitate the creation and sharing of information, ideas, career interests and other forms of expression dedicated to community-based input, interaction, content-sharing and collaboration via online communities and networks. In Italy more than 25 million of the population use social media among different generation for various purposes. Social media also claimed to have negative impacts on personality and physiological aspects of human beings, yet these statistics variables have not much been emphasized in previous studies. The objective of this paper is to compare and discuss the use of different social network platforms among Italians, specific purpose and to identify duration of usage. These finding will give us knowledge of the popular social media platform and usage among different age groups and to determine the usefulness and draw backs spending inordinate amount of time in social media usage among Italian population living in Italy.
