Security and Online Social Networks
Security and Online Social Networks Javier Echaiz and Jorge Ardenghi Laboratorio de Investigaci´on de Sistemas Distribuidos (LISiDi), Departamento de Ciencias e Ingenier´ıa de la Computaci´on Tel´efono: +54 291 4595135, Fax: +54 291 4595136 Universidad Nacional del Sur, Bah´ıa Blanca (8000), Argentina {je,jra}@cs.uns.edu.ar, WWW home page: http://lisidi.cs.uns.edu.ar Abstract. In the last few years we have witnessed a sustained rise in the popularity of online Social Network Sites (SNSs) such as Twitter, Facebook, Myspace, Flickr, LinkedIn, FriendFeed, Google Friend Con- nect, Yahoo! Groups, etc., which are some of the most visited websites worldwide. However, since they are are easy to use and the users are often not aware of the nature of the access of their profiles, they often reveal information which should be kept away from the public eyes. As a result, these social sites may originate security related threats for their members. This paper highlights the benefits of safe use of SNSs and emphasizes the most important threats to members of SNSs. Moreover, we will show the main factors behind these threats. Finally we present policy and technical recommendations in order to improve security without compromising the benefits of information sharing through SNSs. Keywords: Online Social Network, Privacy, Profile squatting, Identity threat, Image Tagging and Cross-profiling. 1 Introduction The advent of the Internet has given rise to many forms of online sociality, from the old e-mail and Usenet services to the more recent instant messaging (IM), blogging, and online social services. Among these, the technological phenomenon that has acquired the greatest popularity in this 21st century is the latter, the Social Networking Sites (SNSs). -
M&A @ Facebook: Strategy, Themes and Drivers
A Work Project, presented as part of the requirements for the Award of a Master Degree in Finance from NOVA – School of Business and Economics M&A @ FACEBOOK: STRATEGY, THEMES AND DRIVERS TOMÁS BRANCO GONÇALVES STUDENT NUMBER 3200 A Project carried out on the Masters in Finance Program, under the supervision of: Professor Pedro Carvalho January 2018 Abstract Most deals are motivated by the recognition of a strategic threat or opportunity in the firm’s competitive arena. These deals seek to improve the firm’s competitive position or even obtain resources and new capabilities that are vital to future prosperity, and improve the firm’s agility. The purpose of this work project is to make an analysis on Facebook’s acquisitions’ strategy going through the key acquisitions in the company’s history. More than understanding the economics of its most relevant acquisitions, the main research is aimed at understanding the strategic view and key drivers behind them, and trying to set a pattern through hypotheses testing, always bearing in mind the following question: Why does Facebook acquire emerging companies instead of replicating their key success factors? Keywords Facebook; Acquisitions; Strategy; M&A Drivers “The biggest risk is not taking any risk... In a world that is changing really quickly, the only strategy that is guaranteed to fail is not taking risks.” Mark Zuckerberg, founder and CEO of Facebook 2 Literature Review M&A activity has had peaks throughout the course of history and different key industry-related drivers triggered that same activity (Sudarsanam, 2003). Historically, the appearance of the first mergers and acquisitions coincides with the existence of the first companies and, since then, in the US market, there have been five major waves of M&A activity (as summarized by T.J.A. -

Strategic Use of Online Social Networks for Librarian Current Awareness
Keeping up: strategic use of online social networks for librarian current awareness Sue Cook, Information Specialist, CSIRO Information Management and Technology [email protected] Constance Wiebrands, Manager, Flexible Delivery and Lending Services, Curtin University Library [email protected] Abstract: Librarians were surveyed in August 2009 about their use of online social networks for professional information. This paper describes the features of online social networking tools that facilitate the flow of relevant current awareness information. Practical methods that can be used strategically within tools to ensure that information is professionally relevant are described, including methods of discovery and evaluation. Introduction As librarians distributing current awareness information, we know that there are various parameters that are included in the evaluation of a desirable current awareness tool. The tool should be able to deliver current, relevant information without a huge burden in time and effort for the client or adding to their information overload. We need to apply these same criteria in assessing our own current awareness needs. Librarian information sources – journals, conference papers, blogs - are either too slow to publication to be truly current or too numerous to effectively monitor. A scan of the Twibes Twitter directory in May 2009 found that 781 users who identified as librarians had registered on the directory. There were 249 members of the Library Society of the World Friendfeed group, 528 members of the ALIA Facebook group and over 500 other librarian groups. The members of these communities are not only sharing information about themselves but information about their work and professional lives. -
