Hop Integrity in the Internet introduces a new security defense, hop integrity, that can be used against denial-of-service attacks in the Internet. If a message that is part of a denial-of-service attack is originated by an adversarial host in the Internet and if the message header includes a wrong address for the originating host (in order to hide the true source of the attack), then the message will be classified as modified or replayed and will be discarded by the first router that receives the message in the Internet.

A suite of protocols for providing hop integrity in the Internet is discussed in great detail. In particular, each protocol in the suite is specified and verified using an abstract and formal notation called the Secure Protocol Notation. The protocols include:

- Secure address resolution

- Weak hop integrity

- Strong hop integrity using soft sequence numbers

- Strong hop integrity using hard sequence numbers

Other benefits of hop integrity extend to secure routing, mobile IP, and IP multicast.

The increasing demand for sophisticated network applications, allied to the growth of the Internet traffic, has lead to great efforts in the search of improvements in data transmission technologies with the intention of satisfying the increasing demand for bandwidth. So far as optical networking is concerned, WDM (Wavelength Division Multiplexing) appears as the main advance in the transmission area, because it allows transmission rates near to the theoretical limit of optical fibers, of the order of dozens of terabits a second [1]. An essential issue in optical network design is defining how the network will be controlled, that is, what type of signalling will be responsible for resource reservation, route determination and fault handling, among other functions that constitute the control plane. Label switching, which in IP networks is exemplified by MPLS (Multiprotocol Label Switching) [2], was extended through GMPLS (Generalized Multiprotocol Label Switching) [3] to operate with several different network technologies, where the label can be represented in other ways, for example, as time-slots in TDM networks, as physical switch ports and as wavelengths (lambdas) in WDM networks.

This work addresses stealthy peripheral-based attacks on host computers and presents a new approach to detecting them. Peripherals can be regarded as separate systems that have a dedicated processor and dedicated runtime memory to handle their tasks. The book addresses the problem that peripherals generally communicate with the host via the host's main memory, storing cryptographic keys, passwords, opened files and other sensitive data in the process - an aspect attackers are quick to exploit. Here, stealthy malicious software based on isolated micro-controllers is implemented to conduct an attack analysis, the results of which provide the basis for developing a novel runtime detector. The detector reveals stealthy peripheral-based attacks on the host's main memory by exploiting certain hardware properties, while a permanent and resource-efficient measurement strategy ensures that the detector is also capable of detecting transient attacks, which can otherwise succeed when the applied strategy only measures intermittently. Attackers exploit this strategy by attacking the system in between two measurements and erasing all traces of the attack before the system is measured again.

In his latest book, a pre-eminent information security pundit confessed that he was wrong about the solutions to the problem of information security. It's not technology that's the solution, but the human factor-people. But even infosec policies and procedures are insufficient if employees don't know about them, or why they're important, or what can happen to them if they ignore them. The key, of course, is continuous awareness of the problems and the solutions.
Building an Information Security Awareness Program addresses these concerns. A reference and self-study guide, it goes step-by-step through the methodology for developing, distributing, and monitoring an information security awareness program. It includes detailed instructions on determining what media to use and where to locate it, and it describes how to efficiently use outside sources to optimize the output of a small staff. The author stresses the importance of security and the entire organizations' role and responsibility in protecting it. He presents the material in a fashion that makes it easy for nontechnical staff members to grasp the concepts. These attributes render Building an Information Security Awareness Program an immensely valuable reference in the arsenal of the IS professional.

Approaches to legal ontologies constitutes a collective reflection on the foundations of legal ontology engineering, by exploring current methodologies and theoretical approaches to defining legal ontologies, their divergences and complementarity and the challenges still to be faced. It gathers contributions from leading experts regarding their theoretical commitments and methodological approaches derived from a long experience in the area and presents a mature reflection on achievements and current shortcomings. The various authors reconstruct their concrete methodological frameworks by retrieving the more or less explicit theoretical choices that have guided their work on legal ontology engineering over the last years. This results in the presentation of apparently opposed but in fact complementary rationales for ontology building in the legal domain (legal-theoretical, sociolegal, philosophical, among others) that address the various dimensions of legal knowledge and its conceptual modelling. The book provides the reader with a unique source regarding the current theoretical landscape in legal ontology engineering as well as on foreseeable future trends for the definition of conceptual structures to enhance the automatic processing and retrieval of legal information in the Semantic Web framework. It will thus interest researchers in the domains of the SW, legal informatics, Artificial Intelligence and law, legal theory and legal philosophy, as well as developers of e-government applications based on the intelligent management of legal or public information to provide both back-office and front-office support.

Handling IPv6 for the first time is a challenging task even for the experienced system administrator. New concepts and mechanisms make it necessary to rethink well-established methods of the IPv4 protocol.

This book is a practical guide to IPv6 addressing Unix and network administrators with experience in TCP/IP(v4) but not necessarily any IPv6 knowledge. It focuses on reliable and efficient operation of IPv6 implementations available today rather than on protocol specifications. Consequently, it covers the essential concepts - using instructive and thoroughly tested examples - on how to configure, to administrate, and to debug IPv6 setups. These foundations are complemented by discussions of best practices and strategic considerations aimed at overall efficiency, reliability, maintainability, and interoperation.

The examples in this book cover all relevant aspects concerning Debian GNU/Linux, FreeBSD, and Solaris. Examples about other Unix derivatives are available online at www.benedikt-stockebrand.de.
