Tutorial No. 1:

Day: Monday December 20th, 2012

Time: 10:00 - 11:15 + 15min Q&A

Venue: Emirates Room A, Crown Plaza Hotel 

Title: Fraud and Service Misuse in Voice over IP (VoIP) networks

Presenters: Dr. Yacine Rebahi and Dr. Pascal Lorenz

Abstract: The migration from circuit-switched networks to packet-switched networks necessitates the investigation of related issues such as service delivery, QoS, security, and service fraud and misuse. The latter can be seen as a combination of accounting and security aspects. In traditional telecommunication networks, fraud accounts for annual losses at an average of 3% to 5% of the operators' revenue and still increasing at a rate of more than 10% yearly. It is also expected that in VoIP networks, the situation will be worse due to the lack of strong built-in security mechanisms, and the use of open standards.

Despite significant advances in fraud detection technologies, fraud losses continue to pose a significant problem to many industries, including telecommunications, banking and finance, insurance, e-commerce and many others.

The objective of the tutorial is to give the audience a deep understanding of the fraud problem in the next generation telecommunication infrastructures, the currently proposed anti-fraud solutions, and their applicability to the VoIP case. 

Presenters' Biographies:

Dr. Yacine Rebahi has a PhD in mathematics and a Habilitation (In Europe, it is a degree comparable to level of Professorial Certification) in computer science. Currently senior researcher leading the Trusted Applications and Network (TAN) team within the Next Generation Network Infrastructure (NGNI) department at the Fraunhofer FOKUS. Prior to joining FOKUS in 2002, he worked at Ericsson Canada on Voice over IP (VoIP) related applications. At Fraunhofer FOKUS, he has been leading the work on various European, national, and industry projects. His research activities are mostly dedicated to emergency services in Next Generation Networks, Security in Machine-2-Machine (M2M) communication; and security in fixed and mobile networks, eGovernment, and Future Internet. Dr Rebahi is currently investigating the use of various data mining tools in the context of fraud detection in VoIP networks. He is also investigating the use of the new European eID cards in reducing hoax calls related to emergency services. Dr. Rebahi is an IEEE member and has over 50 publications between journal and conference papers, and chapter books. Dr. Rebahi has been leading several research activities in the following security fields: Trust building in ad-hoc networks, Security and privacy issues in the context of policy making process, DoS attacks detection in VoIP networks, Spam mitigation in VoIP environments, Fraud and service misuse in VoIP networks, and security in self-organizing networks.

Prof. Pascal Lorenz received his M.Sc. (1990) and Ph.D. (1994) from the University of Nancy, France. Between 1990 and 1995 he was a research engineer at WorldFIP Europe and at Alcatel-Alsthom. He is a professor at the University of Haute-Alsace, France, since 1995. His research interests include QoS, wireless networks and high-speed networks .He is the author/co-author of 3 books, 3 patents and 200 international publications in refereed journals and conferences.

He has served as Co-Guest Editor for special issues of IEEE Communications Magazine, Networks Magazine, Wireless Communications Magazine, Telecommunications Systems and LNCS. He is senior member of the IEEE and member of many international program committees. He has organized many conferences, chaired several technical sessions and gave tutorials at major international conferences.

Tutorial No. 2:

Day: Monday December 20th, 2012

Time: 11:30 - 12:45 + 15min Q&A

Venue: Emirates Room A, Crown Plaza Hotel 

Title: IEEE 802.11 WLAN Standards and Security

Presenter: Dr. Tarek N. Saadawi

Abstract: The Wi-Fi, IEEE 802.11 standard is widely used to provide wireless local area networks (WLAN) solutions both for temporary connections in hotspots in cafes, airports, hotels and similar places as well as within office scenarios and home networks.  This tutorial presents a comprehensive review of WLAN, and analyzes the 802.11i standard to address security issues.

There is a variety  of standards under the IEEE 802.11 each with a letter suffix. These cover everything from the wireless standards themselves, to standards for security aspects, quality of service and the like. Of these the standards that are most widely known are the network bearer standards, 802.11a, 802.11b, 802.11g and 802.11n, and the security standard IEEE 802.11i.

The tutorial first presents a brief overview of the Wireless Local Area Network as specified in IEEE 802.11 and then presents the various IEEE 802.11 standards including IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11i (security & WEP/WPA), IEEE 802.11n, IEEE 802.11ac, IEEE 802.11ad microwave Wi-Fi.  The second part of the course will focus on the security aspects of IEEE 802.11 with focus on Wired Equivalent Privacy (WEP), WEP problems, 802.11i and its phases of operation, and 802.1X.
