Academics and Social Networking Sites: Benefits, Problems and Tensions in Professional Engagement with Online Networking

The web has had a profound effect on the ways people interact, with online social networks arguably playing an important role in changing or augmenting how we connect with others. However, uptake of online social networking by the academic community varies, and needs to be understood. This paper presents an independent, novel analysis of a large-scale dataset published by Nature Publishing Group detailing the results of a survey about academics use of online social networking services. An open coding approach was used to analyse 480 previously unused text responses. The analysis revealed a wide range of benefits and also problems associated with engaging with online networking, and tensions within this. The analysis provides further insight into the nuances of uptake, by exploring clusters of co-reported benefits and problems within the qualitative analysis. The findings will help move forward current debates surrounding social media use by academics from being viewed in solely beneficial terms, towards an understanding of the problems and tensions that arise through academic work online

A survey of intrusion detection techniques in Cloud

Cloud computing provides scalable, virtualized on-demand services to the end users with greater flexibility and lesser infrastructural investment. These services are provided over the Internet using known networking protocols, standards and formats under the supervision of different managements. Existing bugs and vulnerabilities in underlying technologies and legacy protocols tend to open doors for intrusion. This paper, surveys different intrusions affecting availability, confidentiality and integrity of Cloud resources and services. It examines proposals incorporating Intrusion Detection Systems (IDS) in Cloud and discusses various types and techniques of IDS and Intrusion Prevention Systems (IPS), and recommends IDS/IPS positioning in Cloud architecture to achieve desired security in the next generation networks
