Secure Computer and Network Systems

Modeling, Analysis and Design

Nong Ye, Arizona State University, USA

Computer and network systems have given us unlimited opportunities of reducing cost, improving efficiency, and increasing revenues, as demonstrated by an increasing number of computer and network applications. Yet, our dependence on computer and network systems has also exposed us to new risks, which threaten the security of, and present new challenges for protecting our assets and information on computer and network systems. The reliability of computer and network systems ultimately depends on security and quality of service (QoS) performance.

This book presents quantitative modeling and analysis techniques to address these numerous challenges in cyber attack prevention and detection for security and QoS, including:

the latest research on computer and network behavior under attack and normal use conditions;

new design principles and algorithms, which can be used by engineers and practitioners to build secure computer and network systems, enhance security practice and move to providing QoS assurance on the Internet;

mathematical and statistical methods for achieving the accuracy and timeliness of cyber attack detection with the lowest computational overhead;

guidance on managing admission control, scheduling, reservation and service of computer and network jobs to assure the service stability and end-to-end delay of those jobs even under Denial of Service attacks or abrupt demands.

"Secure Computer and Network Systems: Modeling, Analysis and Design" is an up-to-date resource for practising engineers and researchers involved in security, reliabilityand quality management of computer and network systems. It is also a must-read for postgraduate students developing advanced technologies for improving computer network dependability.

With the spread of web-enabled desktop clients and web-server based applications, developers can no longer afford to treat security as an afterthought. It's one topic, in fact, that .NET forces you to address, since Microsoft has placed security-related features at the core of the .NET Framework. Yet, because a developer's carelessness or lack of experience can still allow a program to be used in an unintended way, Programming .NET Security shows you how the various tools will help you write secure applications.

The second edition focuses on the platform features of Java that provide security--the class loader, bytecode verifier, and security manager--and recent additions to Java that enhance this security model: digital signatures, security providers, and the access controller. The book covers in depth the security model of Java 2, version 1.3, including the two new security APIs: JAAS and JSSE.

From the world's most renowned security technologist, Bruce Schneier, this 20th Anniversary Edition is the most definitive reference on cryptography ever published and is the seminal work on cryptography. Cryptographic techniques have applications far beyond the obvious uses of encoding and decoding information. For developers who need to know about capabilities, such as digital signatures, that depend on cryptographic techniques, there's no better overview than Applied Cryptography, the definitive book on the subject. Bruce Schneier covers general classes of cryptographic protocols and then specific techniques, detailing the inner workings of real-world cryptographic algorithms including the Data Encryption Standard and RSA public-key cryptosystems. The book includes source-code listings and extensive advice on the practical aspects of cryptography implementation, such as the importance of generating truly random numbers and of keeping keys secure. "...the best introduction to cryptography I've ever seen...The book the National Security Agency wanted never to be published..." -Wired Magazine "...monumental ...fascinating ...comprehensive ...the definitive work on cryptography for computer programmers . .." -Dr. Dobb's Journal "...easily ranks as one of the most authoritative in its field." -PC Magazine The book details how programmers and electronic communications professionals can use cryptography-the technique of enciphering and deciphering messages-to maintain the privacy of computer data. It describes dozens of cryptography algorithms, gives practical advice on how to implement them into cryptographic software, and shows how they can be used to solve security problems. The book shows programmers who design computer applications, networks, and storage systems how they can build security into their software and systems. With a new Introduction by the author, this premium edition will be a keepsake for all those committed to computer and cyber security.
