Recent Advances in Intrusion Detection

On behalf of the program committee, it is our pleasure to present to you the proceedings of the Fifth Symposium on Recent Advances in Intrusion Detection (RAID). Since its ?rst edition in 1998, RAID has established itself as the main annual intrusion detection event, attracting researchers, practitioners, and v- dors from all over the world. The RAID 2002 program committee received 81 submissions (64 full papers and 17 extended abstracts) from 20 countries. This is about 50% more than last year. All submissions were carefully reviewed by at least three program comm- tee members or additional intrusion-detection experts according to the criteria ofscienti?cnovelty,importancetothe?eld,andtechnicalquality.Finalselection took place at a meeting held on May 15-16, 2002, in Oakland, USA. Sixteen full papers were selected for presentation and publication in the conference proc- dings. In addition, three extended abstracts of work in progress were selected for presentation. The program included both fundamental research and practical issues. The seven sessions were devoted to the following topics: anomaly detection, steppi- stonedetection,correlationofintrusion-detectionalarms,assessmentofintrusi- detectionsystems,intrusiontolerance,legalaspects,adaptiveintrusion-detection systems, and intrusion-detection analysis. RAID 2002 also hosted a panel on "Cybercrime," a topic of major concern for both security experts and the public. Marcus J. Ranum, the founder of Network Flight Recorder, Inc., delivered a keynote speech entitled "Challenges for the Future of Intrusion Detection".
