Book Description
Au cours des dernières années, les équipements mobiles permettant de se connecter à distance au réseau d’entreprise (smartphones, ordinateurs ultraportables…) ont connu une croissance fulgurante. Les perspectives futures de développement et les nouvelles pratiques comme le BYOD (bring your own device) exposent plus que jamais le système d’information d’entreprise à des menaces d’origines diverses. La maîtrise de la sécurité des accès mobiles devient un enjeu stratégique pour l’entreprise. Cet ouvrage didactique présente un panorama des risques pesant sur les accès à distance. L’exemple concret d’un utilisateur lambda et des différentes attaques subies lors d’une « journée ordinaire » sensibilise le lecteur aux défenses standard et spécifiques qui existent pour le protéger. Le domaine de la sécurité n’étant pas uniquement lié aux seuls aspects techniques, le lien entre ces différentes recommandations et l’une des principales approches méthodologiques en la matière (ISO/IEC 27002) est également exposé.

Book Description
AAA (Authentication, Authorization, Accounting) describes a framework for intelligently controlling access to network resources, enforcing policies, and providing the information necessary to bill for services. AAA and Network Security for Mobile Access is an invaluable guide to the AAA concepts and framework, including its protocols Diameter and Radius. The authors give an overview of established and emerging standards for the provision of secure network access for mobile users while providing the basic design concepts and motivations. AAA and Network Security for Mobile Access: Covers trust, i.e., authentication and security key management for fixed and mobile users, and various approaches to trust establishment. Discusses public key infrastructures and provides practical tips on certificates management. Introduces Diameter, a state-of-the-art AAA protocol designed to meet today’s reliability, security and robustness requirements, and examines Diameter-Mobile IP interactions. Explains RADIUS (Remote Authentication Dial-In User Services) and its latest extensions. Details EAP (Extensible Authentication Protocol) in-depth, giving a protocol overview, and covering EAP-XXX authentication methods as well as use of EAP in 802 networks. Describes IP mobility protocols including IP level mobility management, its security and optimizations, and latest IETF seamless mobility protocols. Includes a chapter describing the details of Mobile IP and AAA interaction, illustrating Diameter Mobile IP applications and the process used in CDMA2000. Contains a section on security and AAA issues to support roaming, discussing a variety of options for operator co-existence, including an overview of Liberty Alliance. This text will provide researchers in academia and industry, network security engineers, managers, developers and planners, as well as graduate students, with an accessible explanation of the standards fundamental to secure mobile access.

Book Description
Marginality does not mean isolation. In Africa where people are permanently on the move in search, inter alia, of a 'better elsewhere', marginality means disconnection to obvious possibilities and the invisibility of the myriad connections that make life possible for the ordinarily sidestepped. This book is about the workings of networks of the mobile in Africa, a continent usually associated with the 'global shadows' of the world. How do changes in the possibilities for communication, with the recent hype of mobile technology, influence the social and economic dynamics in Africa's mobile margins? To what extent is the freedom associated with new Information and Communication Technologies reality or disillusion for people dwelling in the margins? Are ordinary Africans increasingly Side@Ways? How social are these emergent Side@Ways? Contributions to answering these and related questions are harvested from ethnographic insights by team members of the WOTRO funded 'Mobile Africa revisited' research programme hosted by the African Studies Centre, Leiden, The Netherlands.

Doctoral Thesis / Dissertation from the year 2011 in the subject Computer Science - Internet, New Technologies, Lille 1 University (Laboratoire d'Informatique Fondamentale de Lille), course: Security in Wireless Multi-hop Networks, language: English, abstract: While the rapid proliferation of mobile devices along with the tremendous growth of various applications using wireless multi-hop networks have significantly facilitate our human life, securing and ensuring high quality services of these networks are still a primary concern. In particular, anomalous protocol operation in wireless multi-hop networks has recently received considerable attention in the research community. These relevant security issues are fundamentally different from those of wireline networks due to the special characteristics of wireless multi-hop networks, such as the limited energy resources and the lack of centralized control. These issues are extremely hard to cope with due to the absence of trust relationships between the nodes. To enhance security in wireless multi-hop networks, this dissertation addresses both MAC and routing layers misbehaviors issues, with main focuses on thwarting black hole attack in proactive routing protocols like OLSR, and greedy behavior in IEEE 802.11 MAC protocol. Our contributions are briefly summarized as follows. As for black hole attack, we analyze two types of attack scenarios: one is launched at routing layer, and the other is cross layer. We then provide comprehensive analysis on the consequences of this attack and propose effective countermeasures. As for MAC layer misbehavior, we particularly study the adaptive greedy behavior in the context of Wireless Mesh Networks (WMNs) and propose FLSAC (Fuzzy Logic based scheme to Struggle against Adaptive Cheaters) to cope with it. A new characterization of the greedy behavior in Mobile Ad Hoc Networks (MANETs) is also introduced. Finally, we design a new backoff scheme to quickly detect the greedy nodes that do not comply with IEEE 802.11 MAC protocol, together with a reaction scheme that encourages the greedy nodes to become honest rather than punishing them.
