This book presents the Proceedings of the Fifth Collaborative Research Symposium on Security, E-learning, Internet and Networking, hosted by the University of Applied Sciences Darmstadt, Germany, on the 25-29th November 2009. All authors are researchers from the Universities of Plymouth, Darmstadt and Glynd_r University in Wales. They are all PhD students or postdoctoral researchers working in the presented areas. We hope this book can show new and interesting ideas for a wide audience especially for those who could not attend the Symposium.
