Foreword from the Program Chairs These proceedings contain the papers selected for presentation at the 10th - ropean Symposium on Research in Computer Security (ESORICS), held S- tember 12–14, 2005 in Milan, Italy. In response to the call for papers 159 papers were submitted to the conf- ence. These paperswere evaluated on the basis of their signi?cance, novelty,and technical quality. Each paper was reviewed by at least three members of the program committee. The program committee meeting was held electronically, holding intensive discussion over a period of two weeks. Of the papers subm- ted, 27 were selected for presentation at the conference, giving an acceptance rate of about 16%. The conference program also includes an invited talk by Barbara Simons. There is a long list of people who volunteered their time and energy to put together the symposiom and who deserve acknowledgment. Thanks to all the members of the program committee, and the external reviewers, for all their hard work in evaluating and discussing papers. We are also very grateful to all those people whose work ensured a smooth organizational process: Pierangela Samarati, who served as General Chair, Claudio Ardagna, who served as P- licity Chair, Dieter Gollmann who served as Publication Chair and collated this volume, and Emilia Rosti and Olga Scotti for helping with local arrangements. Last, but certainly not least, our thanks go to all the authors who submitted papers and all the attendees. We hope you ?nd the program stimulating.

To defend against computer and network attacks, multiple, complementary security devices such as intrusion detection systems (IDSs), and firewalls are widely deployed to monitor networks and hosts. These various IDSs will flag alerts when suspicious events are observed. This book is an edited volume by world class leaders within computer network and information security presented in an easy-to-follow style. It introduces defense alert systems against computer and network attacks. It also covers integrating intrusion alerts within security policy framework for intrusion response, related case studies and much more.

The number of worldwide VoIP customers is well over 38 million. Thanks to the popularity of inexpensive, high-quality services, it's projected to increase to nearly 250 million within the next three years. The VoIP Handbook: Applications, Technologies, Reliability, and Security captures the state of the art in VoIP technology and serves as the comprehensive reference on this soon-to-be ubiquitous technology. It provides: A step-by-step methodology to evaluate VoIP performance prior to network implementation An invaluable overview of implementation challenges and several VoIP multipoint conference systems Unparalleled coverage of design and engineering issues such VoIP traffic, QoS requirements, and VoIP flow As this promising technology’s popularity increases, new demands for improved quality, reduced cost, and seamless operation will continue to increase. Edited by preeminent wireless communications experts Ahson and Illyas, the VoIP Handbook guides you to successful deployment.

Provides a broad working knowledge of all the major security issues affecting today's enterprise IT activities. Multiple techniques, strategies, and applications are examined, presenting the tools to address opportunities in the field. For IT managers, network administrators, researchers, and students.

This book constitutes the refereed proceedings of the 20th Annual Working Conference on Data and Applications Security held in Sophia Antipolis, France, in July/August 2006. The 22 revised full papers presented were carefully reviewed and selected from 56 submissions. The papers explore theory, technique, applications, and practical experience of data and application security covering a number of diverse research topics such as access control, privacy, and identity management.

This Springer Brief examines the tools based on attack graphs that help reveal network hardening threats. Existing tools detail all possible attack paths leading to critical network resources. Though no current tool provides a direct solution to remove the threats, they are a more efficient means of network defense than relying solely on the experience and skills of a human analyst. Key background information on attack graphs and network hardening helps readers understand the complexities of these tools and techniques. A common network hardening technique generates hardening solutions comprised of initially satisfied conditions, thereby making the solution more enforceable. Following a discussion of the complexity issues in this technique, the authors provide an improved technique that considers the dependencies between hardening options and employs a near-optimal approximation algorithm to scale linearly with the size of the inputs. Also included are automated solutions for hardening a network against sophisticated multi-step intrusions. Network Hardening: An Automated Approach to Improving Network Security is a valuable resource for researchers and professionals working in network security. It is also a useful tool for advanced-level students focused on security in computer science and electrical engineering.

These proceedings present technical papers selected from the 2012 International Conference on Intelligent Systems and Knowledge Engineering (ISKE 2012), held on December 15-17 in Beijing. The aim of this conference is to bring together experts from different fields of expertise to discuss the state-of-the-art in Intelligent Systems and Knowledge Engineering, and to present new findings and perspectives on future developments. The proceedings introduce current scientific and technical advances in the fields of artificial intelligence, machine learning, pattern recognition, data mining, knowledge engineering, information retrieval, information theory, knowledge-based systems, knowledge representation and reasoning, multi-agent systems, and natural-language processing, etc. Furthermore they include papers on new intelligent computing paradigms, which combine new computing methodologies, e.g., cloud computing, service computing and pervasive computing with traditional intelligent methods. By presenting new methodologies and practices, the proceedings will benefit both researchers and practitioners who want to utilize intelligent methods in their specific fields.
