Description

Introduces aspects on security threats and their countermeasures in both fixed and wireless networks, advising on how countermeasures can provide secure communication infrastructures. Enables the reader to understand the risks of inappropriate network security, what mechanisms and protocols can be deployed to counter these risks, and how these mechanisms and protocols work.

About Author

Guenter Schaefer, Professor, Technische Universit t Ilmenau, Germany. After obtaining his Ph.D. degree (1998) he worked at Ecole Nationale Sup rieure des T l communications, Paris, France (1999 - 2000). Between 2000 and 2005, he was researcher at Technische Universitaet Berlin, Germany where he was leading the network security laboratory. Since 2005 he is at his current post leading the Telematics/Computer Networks research group. His research interests lie in the areas of network security, networking protocols, mobile communications, and innovative communication services/architectures, and he regularly gives courses on network security, networking subjects and basics of computer science. Michael Rossberg, PostDoc Researcher, Technische Universit t Ilmenau, Germany. In 2011 he obtained his Ph.D. in computer science with a thesis on peer-to-peer-based auto-configuration of large scale IPsec VPNs. His research interests lie in network security and performance evaluation/optimization. In 2010, Michael Rossberg and Guenter Schaefer were jointly awarded with the third prize of the German IT Security Award for their work on automatic configuration of large scale VPNs.
