Principles Systems And Applications Of Ip Telecommunications Services And Security For Next Generation Networks

This book constitutes the thoroughly refereed proceedings of the 10th International Workshop on Principles, Systems and Applications of IP Telecommunications, held in Heidelberg, Germany, in July 2008. The 16 full papers presented were carefully reviewed and selected from a total of 56 submissions. Topics covered include recent advances in the domains of convergent networks, VoIP security, and multimedia service environments for next generation networks.

Cyber attacks are on the rise. The media constantly report about data breaches and increasingly sophisticated cybercrime. Even governments are affected. At the same time, it is obvious that technology alone cannot solve the problem. What can countries do? Which issues can be addressed by policies and legislation? How to draft a good law? The report assists countries in understanding what cybercrime is about, what the challenges are in fighting such crime and supports them in drafting policies and laws.

This journal aims to contribute to the advancement of knowledge and awareness of the international community's priority issues in the field of justice, crime prevention and human rights. The Magazine pursues the promotion of innovative dialogue by spreading awareness, creating consensus and a sense of shared responsibility of the problems that affect the global community. As a forum for long-term change, the Magazine endeavors to promote democratic values, civil stability, and aid the international community in developing actions towards greater peace, justice and security for all members of social, civil and political society.

The management of services and operations in today’s organizations are - coming increasingly dependent on their enterprise local area network (enterprise LAN). An enterprise LAN consists of a set of network zones (logical group of networkelements)correspondingto di?erent departments orsections,connected through various interface switches (typically, Layer-3 switches). The network service accesses between these zones and also with the external network (e. g. , Internet) are governed by a global network security policy of the organization. This global policy is de?ned as a collection of service access rules across various network zones where the services referred network applications conforming to TCP/IP protocol. For example, some of the known network services aressh, t- net,http etc. In reality, the security policy may be incompletely speci?ed; which explicitly states the “permit” and “deny” access rules between speci?c network zones keeping remaining service access paths as unspeci?ed. The global security policy is realized in the network by con?guring the n- work interfaces with appropriate sets of access control rules (ACLs). One of the major challenges in network security management is ensuring the conformation of the distributed security implementations with the global security policy.

This book gives a detailed overview of SIP specific security issues and how to solve them While the standards and products for VoIP and SIP services have reached market maturity, security and regulatory aspects of such services are still being discussed. SIP itself specifies only a basic set of security mechanisms that cover a subset of possible security issues. In this book, the authors survey important aspects of securing SIP-based services. This encompasses a description of the problems themselves and the standards-based solutions for such problems. Where a standards-based solution has not been defined, the alternatives are discussed and the benefits and constraints of the different solutions are highlighted. Key Features: Will help the readers to understand the actual problems of using and developing VoIP services, and to distinguish between real problems and the general hype of VoIP security Discusses key aspects of SIP security including authentication, integrity, confidentiality, non-repudiation and signalling Assesses the real security issues facing users of SIP, and details the latest theoretical and practical solutions to SIP Security issues Covers secure SIP access, inter-provider secure communication, media security, security of the IMS infrastructures as well as VoIP services vulnerabilities and countermeasures against Denial-of-Service attacks and VoIP spam This book will be of interest to IT staff involved in deploying and developing VoIP, service users of SIP, network engineers, designers and managers. Advanced undergraduate and graduate students studying data/voice/multimedia communications as well as researchers in academia and industry will also find this book valuable.

Measurement technologies and instrumentation have a multidisciplinary impact in the field of applied sciences. These engineering technologies are necessary in processing information required for renewable energy, biotechnology, power quality, and nanotechnology. Advanced Instrument Engineering: Measurement, Calibration, and Design presents theoretical and practical aspects on the activities concerning measurement technologies and instrumentation. This wide range of new ideas in the field of measurements and instrumentation is useful to researchers, scientists, practitioners, and technicians for their area of expertise.

This volume contains the post-proceedings of the Second International Workshop on Critical Information Infrastructure Security (CRITIS 2007), that was held during October 3–5, 2007 in Benalmadena-Costa (Malaga), Spain, and was hosted by the University of Malaga, Computer Science Department. In response to the 2007 call for papers, 75 papers were submitted. Each paper was reviewed by three members of the Program Committee, on the basis of significance, novelty, technical quality and critical infrastructures relevance of the work reported therein. At the end of the reviewing process, only 29 papers were selected for pres- tation. Revisions were not checked and the authors bear full responsibility for the content of their papers. CRITIS 2007 was very fortunate to have four exceptional invited speakers: Adrian Gheorghe (Old Dominion University, USA), Paulo Veríssimo (Universidade de L- boa, Portugal), Donald Dudenhoeffer (Idaho National Labs, USA), and Jacques Bus (European Commission, INFSO Unit "Security"). The four provided a high added value to the quality of the conference with very significant talks on different and int- esting aspects of Critical Information Infrastructures. In 2007, CRITIS demonstrated its outstanding quality in this research area by - cluding ITCIP, which definitively reinforced the workshop. Additionally, the solid involvement of the IEEE community on CIP was a key factor for the success of the event. Moreover, CRITIS received sponsorship from Telecom Italia, JRC of the European Commission, IRRIIS, IFIP, and IABG, to whom we are greatly indebted.
