On behalf of the Program Committee, it is my pleasure to present the p- ceedings of the 5th GI International Conference on Detection of Intrusions and Malware, and Vulnerability Assessment (DIMVA). Every year since 2004 DIMVA has brought together leading researchers and practitionersfromacademia, governmentandindustrytopresentanddiscussnovel security research. DIMVA is organized by the Security-Intrusion Detection and Response(SIDAR)specialinterestgroupoftheGermanInformaticsSociety(GI). The DIMVA 2008 Program Committee received 42 submissions from 16 d- ferent countries, and from governmental, industrial and academic organizations. All the submissions were carefully reviewed by several members of the Program Committee and evaluated on the basis of scienti?c novelty, importance to the ?eld and technical quality. The ?nal selection took place at the Program C- mittee meeting held on March 28, 2008 at the IBM Zu ]rich Research Laboratory in Switzerland. Thirteen full papers and one extended abstract were selected for presentation and publication in the conference proceedings. The conference took place during July 10-11, 2008, in the France T el ecom R&D/Orange Labs premises of Issy les Moulineaux, near Paris, France, with the program grouped into ?ve sessions. Two keynote speeches were presented by Richard Bejtlich (Director of Incident Response, General Electric) and by Tal Gar?nkel (VMware Inc./Stanford University). The conference program also included a rump session organized by Sven Dietrich of the Stevens Institute of Technology, in which recent research results, works in progress, and other topics of interest to the community were presented."

This book constitutes the refereed proceedings of the 9th International Symposium on Recent Advances in Intrusion Detection, RAID 2006, held in Hamburg, Germany in September 2006. The 16 revised full papers presented were carefully reviewed and selected from 93 submissions. The papers are organized in topical sections on anomaly detection, attacks, system evaluation and threat assessment, malware collection and analysis, anomaly- and specification-based detection, and network intrusion detection.

This book constitutes the refereed proceedings of the 8th International Symposium on Recent Advances in Intrusion Detection held in September 2005. The 15 revised full papers and two practical experience reports were carefully reviewed and selected from 83 submissions. The papers are organized in topical sections on worm detection and containment, anomaly detection, intrusion prevention and response, intrusion detection based on system calls and network-based, as well as intrusion detection in mobile and wireless networks.
