This book captures the state of the art research in the area of malicious code detection, prevention and mitigation. It contains cutting-edge behavior-based techniques to analyze and detect obfuscated malware. The book analyzes current trends in malware activity online, including botnets and malicious code for profit, and it proposes effective models for detection and prevention of attacks using. Furthermore, the book introduces novel techniques for creating services that protect their own integrity and safety, plus the data they manage.

On behalf of the Program Committee, it is our pleasure to present the p- ceedings of the 12th International Symposium on Recent Advances in Intrusion Detection systems (RAID 2009),which took place in Saint-Malo,France, during September 23-25. As in the past, the symposium brought together leading - searchers and practitioners from academia, government, and industry to discuss intrusion detection research and practice. There were six main sessions prese- ingfullresearchpapersonanomalyandspeci?cation-basedapproaches,malware detection and prevention, network and host intrusion detection and prevention, intrusion detection for mobile devices, and high-performance intrusion det- tion. Furthermore, there was a poster session on emerging research areas and case studies. The RAID 2009ProgramCommittee received59 full paper submissionsfrom all over the world. All submissions were carefully reviewed by independent - viewers on the basis of space, topic, technical assessment, and overall balance. The ?nal selection took place at the Program Committee meeting on May 21 in Oakland, California. In all, 17 papers were selected for presentation and p- lication in the conference proceedings. As a continued feature, the symposium accepted submissions for poster presentations which have been published as - tended abstracts, reporting early-stage research, demonstration of applications, or case studies. Thirty posters were submitted for a numerical review by an independent, three-person sub-committee of the Program Committee based on novelty, description, and evaluation. The sub-committee recommended the - ceptance of 16 of these posters for presentation and publication. The success of RAID 2009 depended on the joint e?ort of many people.

Increasingly our critical infrastructures are reliant on computers. We see examples of such infrastructures in several domains, including medical, power, telecommunications, and finance. Although automation has advantages, increased reliance on computers exposes our critical infrastructures to a wider variety and higher likelihood of accidental failures and malicious attacks. Disruption of services caused by such undesired events can have catastrophic effects, such as disruption of essential services and huge financial losses. The increased reliance of critical services on our cyberinfrastructure and the dire consequences of security breaches have highlighted the importance of information security. Authorization, security protocols, and software security are three central areas in security in which there have been significant advances in developing systematic foundations and analysis methods that work for practical systems. This book provides an introduction to this work, covering representative approaches, illustrated by examples, and providing pointers to additional work in the area.
