Negli ultimi decenni il rapido sviluppo delle tecnologie IT ha influito in maniera determinante nella vita dell uomo, trasformando, spesso inconsapevolmente il suo lavoro, le sue abitudini, il suo modo di interagire con il mondo che lo circonda. Il fenomeno della "globalizzazione" dei mercati e solo una delle trasformazioni che l intero pianeta sta attraversando. Anche se i vantaggi derivanti dall utilizzo delle moderne tecnologie di comunicazione ci facilitano nel lavoro e nella attivita ludiche e personali, molte sono le perplessita e i dubbi che attanagliano tutti coloro che le utilizzano. Se l Information Technology rappresenta il "combustibile" indispensabile per la sopravvivenza delle aziende e delle attivita dell uomo, nel contempo puo generare problematicita di grande rilievo. Il testo tratta alcune delle problematiche che destano preoccupazioni rilevanti nel mondo intero come il consumo energetico dei sistemi informatici (incontrollabili e inquinanti), il problema della garanzia della privacy e dell integrita dei dati su Internet, l utilizzo della rete Internet come strumento di controllo delle masse, la possibile sparizione degli attuali sistemi operativi che potranno essere sostituiti dal sistema operativo Web Operating System.

"Blockchains will matter crucially; this book, beautifully and clearly written for a wide audience, powerfully demonstrates how." -Lawrence Lessig "Attempts to do for blockchain what the likes of Lawrence Lessig and Tim Wu did for the Internet and cyberspace-explain how a new technology will upend the current legal and social order... Blockchain and the Law is not just a theoretical guide. It's also a moral one." -Fortune Bitcoin has been hailed as an Internet marvel and decried as the preferred transaction vehicle for criminals. It has left nearly everyone without a computer science degree confused: how do you "mine" money from ones and zeros? The answer lies in a technology called blockchain. A general-purpose tool for creating secure, decentralized, peer-to-peer applications, blockchain technology has been compared to the Internet in both form and impact. Blockchains are being used to create "smart contracts," to expedite payments, to make financial instruments, to organize the exchange of data and information, and to facilitate interactions between humans and machines. But by cutting out the middlemen, they run the risk of undermining governmental authorities' ability to supervise activities in banking, commerce, and the law. As this essential book makes clear, the technology cannot be harnessed productively without new rules and new approaches to legal thinking. "If you...don't 'get' crypto, this is the book-length treatment for you." -Tyler Cowen, Marginal Revolution "De Filippi and Wright stress that because blockchain is essentially autonomous, it is inflexible, which leaves it vulnerable, once it has been set in motion, to the sort of unforeseen consequences that laws and regulations are best able to address." -James Ryerson, New York Times Book Review

Intrusion detection is not for the faint at heart. But, if you are a network administrator chances are you're under increasing pressure to ensure that mission-critical systems are safe--in fact impenetrable--from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders.

Designing a reliable way to detect intruders before they get in is a vital but daunting challenge. Because of this, a plethora of complex, sophisticated, and pricy software solutions are now available. In terms of raw power and features, SNORT, the most commonly used Open Source Intrusion Detection System, (IDS) has begun to eclipse many expensive proprietary IDSes. In terms of documentation or ease of use, however, SNORT can seem overwhelming. Which output plugin to use? How do you to email alerts to yourself? Most importantly, how do you sort through the immense amount of information Snort makes available to you?

Many intrusion detection books are long on theory but short on specifics and practical examples. Not "Managing Security with Snort and IDS Tools." This new book is a thorough, exceptionally practical guide to managing network security using Snort 2.1 (the latest release) and dozens of other high-quality open source other open source intrusion detection programs.

"Managing Security with Snort and IDS Tools" covers reliable methods for detecting network intruders, from using simple packet sniffers to more sophisticated IDS (Intrusion Detection Systems) applications and the GUI interfaces for managing them. A comprehensive but concise guide for monitoring illegal entry attempts, this invaluable new book explains how to shut down and secure workstations, servers, firewalls, routers, sensors and other network devices.

Step-by-step instructions are provided to quickly get up and running with Snort. Each chapter includes links for the programs discussed, and additional links at the end of the book give administrators access to numerous web sites for additional information and instructional material that will satisfy even the most serious security enthusiasts.

"Managing Security with Snort and IDS Tools" maps out a proactive--and effective--approach to keeping your systems safe from attack.

This book introduces audio watermarking methods for copyright protection, which has drawn extensive attention for securing digital data from unauthorized copying. The book is divided into two parts. First, an audio watermarking method in discrete wavelet transform (DWT) and discrete cosine transform (DCT) domains using singular value decomposition (SVD) and quantization is introduced. This method is robust against various attacks and provides good imperceptible watermarked sounds. Then, an audio watermarking method in fast Fourier transform (FFT) domain using SVD and Cartesian-polar transformation (CPT) is presented. This method has high imperceptibility and high data payload and it provides good robustness against various attacks. These techniques allow media owners to protect copyright and to show authenticity and ownership of their material in a variety of applications. * Features new methods of audio watermarking for copyright protection and ownership protection * Outlines techniques that provide superior performance in terms of imperceptibility, robustness, and data payload * Includes applications such as data authentication, data indexing, broadcast monitoring, fingerprinting, etc.

Die Kryptologie, eine jahrtausendealte "Geheimwissenschaft," gewinnt zusehends praktische Bedeutung in Verbindung mit dem Schutz von Kommunikationswegen, Datenbanken und Software. Neben ihrer Nutzung in rechnergestutzten offentlichen Nachrichtensystemen ("offentliche Schlussel") treten zusehends rechnerinterne Anwendungen, die sich auch auf Zugriffsberechtigungen und den Quellenschutz von Software erstrecken.
Der erste Teil des Buches handelt in elf Kapiteln von den Geheimschriften und ihrem Gebrauch - von der Kryptographie. Im zweiten Teil wird in elf weiteren Kapiteln das Vorgehen zum unbefugten Entziffern einer Geheimschrift - die Kryptanalyse - besprochen, wobei sich insbesondere Hinweise fur die Verfahrensbeurteilung ergeben.
Das Buch setzt nur elementare mathematische Kenntnisse voraus. Mit einer Fulle spannender, lustiger und bisweilen anzuglicher Geschichten aus der historischen Kryptologie gewurzt, ist es auch fur den Laien reizvoll zu lesen."

A cryptographic security architecture is the collection of hardware and software that protects and controls the use of encryption keys and similar cryptovariables. It is the foundation for enforcing computer security policies and controls and preempting system misuse.

This book provides a comprehensive design for a portable, flexible high-security cryptographic architecture, with particular emphasis on incorporating rigorous security models and practices. "Cryptographic Security Architecture" unveils an alternative means of building a trustworthy system based on concepts from established software engineering principles and cognitive psychology. Its novel security-kernel design implements a reference monitor that controls access to security-relevant objects and attributes based on a configurable security policy.

Topics and features:

* Builds a concise architectural design that can be easily extended in the future

* Develops an application-specific security kernel that enforces a fully customizable, rule-based security policy

* Presents a new verification technique that allows verification from the high-level specification down to the running code

* Describes effective security assurance in random number generation, and the pitfalls associated therewith

* Examines the generation and protection of cryptovariables, as well as application of the architectural design to cryptographic hardware

The work provides an in-depth presentation of a flexible, platform-independent cryptographic security architecture suited to software, hardware, and hybrid implementations. Security design practitioners, professionals, researchers, and advanced students will find the work an essential resource.

Die Herausforderungen des Data Warehousing liegen langst jenseits von Grundkonzeption und Architektur, die weitestgehend gefestigt sind. Ein ganzheitliches proaktives Datenqualitatsmanagement und integriertes Metadatenmanagement sind fur ein effektives Data-Warehouse-System heute ebenso elementare Voraussetzung wie Datenschutz und Datensicherheit, die im Data-Warehouse-Umfeld neue Bedeutung erlangt haben. Zahlreiche Uberschneidungen und daher Synergiepotenziale bestehen mit Customer Relationship Management, Enterprise Application Integration und Knowledge Management.

Die Autoren zeigen zu diesem Zweck fundierte Konzepte und praktikable Losungen auf, die speziell im zweiten Teil anhand realer Umsetzungen mit bedeutenden europaischen Unternehmen (UBS, Credit Suisse, Swiss Re u. a.) verdeutlicht werden. "

From the original hard cover edition:

In the modern age of almost universal computer usage, practically every individual in a technologically developed society has routine access to the most up-to-date cryptographic technology that exists, the so-called RSA public-key cryptosystem. A major component of this system is the factorization of large numbers into their primes. Thus an ancient number-theory concept now plays a crucial role in communication among millions of people who may have little or no knowledge of even elementary mathematics.

Hans Riesel's highly successful first edition of this book has now been enlarged and updated with the goal of satisfying the needs of researchers, students, practitioners of cryptography, and non-scientific readers with a mathematical inclination. It includes important advances in computational prime number theory and in factorization as well as re-computed and enlarged tables, accompanied by new tables reflecting current research by both the author and his coworkers and by independent researchers.

The book treats four fundamental problems: the number of primes below a given limit, the approximate number of primes, the recognition of primes and the factorization of large numbers. The author provides explicit algorithms and computer programs, and has attempted to discuss as many of the classically important results as possible, as well as the most recent discoveries. The programs include are written in PASCAL to allow readers to translate the programs into the language of their own computers.

The independent structure of each chapter of the book makes it highly readable for a wide variety of mathematicians, students of applied number theory, and others interested in both study and research in number theory and cryptography. "

Kryptografie hat sich in jungster Zeit als eine Wissenschaft gezeigt, bei der mathematische Methoden mit besonderem Erfolg eingesetzt werden konnen. Das Buch stellt die gesamte Kryptografie unter diesem Aspekt vor: Grundlagen und Anwendungen, Verschlusselung und Authentifikation, symmetrische Algorithmen und Public-Key-Verfahren werden entsprechend ihrer Wichtigkeit prasentiert. Das Buch hat den Umfang einer 2-semestrigen Vorlesung, aufgrund seiner klaren Darstellung eignet es sich aber auch hervorragend zum Selbststudium. Zahlreiche Ubungsaufgaben von unterschiedlichem Schwierigkeitsgrad dienen zur Kontrolle des Verstandnisses."

Durante la II guerra mondiale hanno avuto luogo numerosi risultati di rilievo nel campo della crittografia militare. Uno dei meno conosciuti e quello usato dal servizio di intelligence svedese, nei confronti del codice tedesco per le comunicazioni strategiche con i comandi dei paesi occupati nel nord Europa, le cui linee passavano per la Svezia. In tal modo, durante la fase piu critica della guerra la direzione politica e militare svedese era in grado di seguire i piani e le disposizioni dei Tedeschi, venendo a conoscenza dei piu arditi progetti per modificare la propria politica, tenendo la Svezia fuori dalla guerra.

La violazione del codice tedesco e narrata in dettaglio, per la prima volta, con elementi che gli permettono di essere un ottima introduzione al campo della crittografia, oltre che un ritratto vitale e umano della societa del tempo: una disperata condizione bellica, l'intrigo politico e spionistico, il genio del matematico Arne Beurling, le difficolta e i trucchi del mestiere, e il lavoro sistematico e oscuro di una folla di decrittatori.
