Book excerpt: Au départ, les réseaux informatiques filaires n'étaient pas suffisants pour fournir tous les services, mais avec l'avènement des réseaux informatiques sans fil, le vide initial s'est comblé. Donc on peut dire que les entreprises ont besoin des réseaux informatiques filaires et sans fil pour répondre à tous les besoins des utilisateurs. L'implémentation d'un réseau wifi au sein des entreprises exige l'établissement d'une bonne planification cellulaire basée sur un choix judicieux de l'emplacement des différents points d'accès avec une bonne répartition des canaux utilisés. Ceci permet de réduire au maximum les possibilités d'interférences et garantit, en conséquence, de meilleures performances du réseau. Un réseau wifi bien planifié garantit une meilleure performance en matière du débit, de la mobilité et de la portée. Il reste à mettre en oeuvre une politique de sécurité. Ceci se fait par des techniques avancées effectuant la confidentialité et l'intégrité en cryptant les données par des clés solides et par l'identification et l'authentification des utilisateurs pour interdire l'accès au réseau pour des gens non autorisés. Tout ça pour minimiser au maximum les risques qu'un pirate introduit au réseau, lit et modifie les données. Enfin, il faut savoir que la sécurité totale dans les réseaux n'existe pas. Plus le niveau de sécurité est élevé, moins il sera facile de pénétrer et de trouver des informations confidentielles.

Book excerpt: Le préjudice lié au vol d’informations sensibles ou à une intrusion dans les systèmes informatiques des entreprises et des administrations peut avoir des répercussions financières, voire pénales. Les organisations ont par conséquent l’obligation de se protéger vis-à-vis des attaques provenant de sources internes et externes. Cet ouvrage présente les différents mécanismes de sécurité déployés dans les réseaux : - les algorithmes cryptographiques qui renforcent la confidentialité des communications ; - le mécanisme 802.1x, utilisé pour le contrôle d'accès aux réseaux Ethernet et Wi-Fi ; - le mécanisme IPSec et les protocoles SSL, TLS et DTLS, qui fournissent des services de confidentialité et permettent d’établir une association de sécurité et une protection des données ; - le protocole MPLS et les technologies associées servant au cloisonnement du réseau ; - les pare-feux et les sondes de détection et de prévention d’intrusion IDPS, qui assurent la surveillance des données.

Book excerpt: The subject is “Virtual Roaming for data services” and “Seamless Technology change” also called “Number Continuity”.“Virtual Roaming for voice and SMS” was covered in one of the author's previous book. “Virtual Roaming” means that it allows a subscriber to visit a network which his home network does not have an agreement with. The “Seamless Technology change” allows a user to keep all his services including reception of calls and SMS sent to his usual number when he switches his GSM to a Satellite phone or to WiFi. The implementation of Seamless Technology change uses the SS7 Roaming Hub and GTP Hubs technology explained in the first part of the book. The book also contains chapters explaining in detail the steering and anti-steering of roaming, LTE Serving Mobile Location Centers, and Advanced Policy and Charging implementations in LTE and 3G. This is to be used as an easy reference book. All the relevant references to the standards are included chapter by chapter. This is the first book on the two main subjects of Virtual Data Roaming and Seamless Technology change. Keywords:Virtual Roaming, Number Continuity, Seamless technology change, Policy Charging and Control, LTE LBS, Steering of Roaming, GTP Hub, MMS Hub,RADIUS Hub, DIAMETER Hub

Book excerpt: Security Smarts for the Self-Guided IT Professional Protect wireless networks against all real-world hacks by learning how hackers operate. Wireless Network Security: A Beginner's Guide discusses the many attack vectors that target wireless networks and clients--and explains how to identify and prevent them. Actual cases of attacks against WEP, WPA, and wireless clients and their defenses are included. This practical resource reveals how intruders exploit vulnerabilities and gain access to wireless networks. You'll learn how to securely deploy WPA2 wireless networks, including WPA2-Enterprise using digital certificates for authentication. The book provides techniques for dealing with wireless guest access and rogue access points. Next-generation wireless networking technologies, such as lightweight access points and cloud-based wireless solutions, are also discussed. Templates, checklists, and examples give you the hands-on help you need to get started right away. Wireless Network Security: A Beginner's Guide features: Lingo--Common security terms defined so that you’re in the know on the job IMHO--Frank and relevant opinions based on the author's years of industry experience In Actual Practice--Exceptions to the rules of security explained in real-world contexts Your Plan--Customizable checklists you can use on the job now Into Action--Tips on how, why, and when to apply new skills and techniques at work This is an excellent introduction to wireless security and their security implications. The technologies and tools are clearly presented with copious illustrations and the level of presentation will accommodate the wireless security neophyte while not boring a mid-level expert to tears. If the reader invests the time and resources in building a lab to follow along with the text, s/he will develop a solid, basic understanding of what "wireless security" is and how it can be implemented in practice. This is definitely a recommended read for its intended audience. - Richard Austin, IEEE CIPHER, IEEE Computer Society's TC on Security and Privacy (E109, July 23, 2012)

Available in PDF, EPUB and Kindle. Book excerpt: 1. INTRODUCTION With the increasing deployment of wireless networks (802. 11 architecture) in enterprise environments, IT enterprises are working to implement security mechanisms that are equivalent to those existing today for wire-based networks. An important aspect of this is the need to provide secure access to the network for valid users. Existing wired network jacks are located inside buildings already secured from unauthorized access through the use of keys, badge access, and so forth. A user must gain physical access to the building in order to plug a client computer into a network jack. In contrast, a wireless access point (AP) may be accessed from off the premises if the signal is detectable (for instance, from a parking lot adjacent to the building). Thus, wireless networks require secure access to the AP and the ability to isolate the AP from the internal private network prior to user authentication into the network domain. Furthermore, as enterprises strive to provide better availability of mission-critical wireless data, they also face the challenge of maintaining that data's security and integrity. While each connection with a client, a supplier or a enterprise partner can improve responsiveness and efficiency, it also increases the vulnerability of enterprise wireless data to attack. In such an environment, wireless network security is becoming more important every day. Also, with the growing reliance on e-commerce, wireless network-based services and the Internet, enterprises are faced with an ever-increasing responsibility to protect their systems from attack.
