Secure message transmission is of extreme importance in today's information-based society: military, diplomatic, and corporate data transmissions must be safeguarded; so also must the account of every individual who has an automatic-teller bank account or whose purchases are subject to point-of-sale, direct account debiting. The only known way to keep all such transactions secret and authentic is by way of cryptographic techniques. But most cryptosystems in use today are not fool-proof-- their "symmetric" nature allows them to be compromised if either the sender's or the receiver's "key" (decoding algorithm) falls into the wrong hands. This book reports on the enormous amount of work that has been done in the past on the concept, "asymmetric" cryptography.

A state-of-the-art guide to middleware technologies, and their pivotal role in communications networks. Middleware is about integration and interoperability of applications and services running on heterogeneous computing and communications devices. The services it provides - including identification, authentication, authorization, soft-switching, certification and security - are used in a vast range of global appliances and systems, from smart cards and wireless devices to mobile services and e-Commerce. Qusay H. Mahmoud has created an invaluable reference tool that explores the origins and current uses of middleware (highlighting the importance of such technologies as CORBA, J2EE and JMS) and has thus compiled the roadmap to future research in this area. Middleware for Communications: discusses the emerging fields of Peer-to-Peer (P2P) and grid middleware detailing middleware platforms such as JXTA and the Globus middleware toolkit. shows how Middleware will play a significant role in mobile computing. presents a Platform Supporting Mobile Applications (PLASMA) - a middleware platform that consists of components for location, event, and profile handling of Location-Based Services. introduces middleware security focusing on the appropriate aspects of CORBA, J2EE, and .NET and demonstrates how to realize complex security capabilities such as role-based access control (RBAC) and mandatory access control (MAC). discusses how Quality of Service (QoS) component middleware can be combined with Model Driven Architecture (MDA) technologies to rapidly develop, generate, assemble and deploy flexible communications applications. This incomparable overview of middleware for communications is suitable for graduate students and researchers in communications and computing departments. It is also an authoritative guide for engineers and developers working on distributed systems, mobile computing and networked appliances.

Soft computing, as opposed to conventional "hard" computing, tolerates imprecision and uncertainty, in a way very much similar to the human mind. Soft computing techniques include neural networks, evolutionary computation, fuzzy logic, and chaos. The recent years have witnessed tremendous success of these powerful methods in virtually all areas of science and technology, as evidenced by the large numbers of research results published in a variety of journals, conferences, as weil as many excellent books in this book series on Studies in Fuzziness and Soft Computing. This volume is dedicated to recent novel applications of soft computing in communications. The book is organized in four Parts, i.e., (1) neural networks, (2) evolutionary computation, (3) fuzzy logic and neurofuzzy systems, and (4) kernel methods. Artificial neural networks consist of simple processing elements called neurons, which are connected by weights that may be adjusted during learning. Part 1 of the book has seven chapters, demonstrating some of the capabilities of two major types of neural networks, i.e., multiplayer perceptron (MLP) neural networks and Hopfield-type neural networks.

The Internet Encyclopedia in a 3-volume reference work on the internet as a business tool, IT platform, and communications and commerce medium.

The terrorist attacks of September 11 signaled the dawn of a new age of warfare: InfoWar. The greatest challenge facing the IT community in the 21st Century is securing networks from malicious attacks. The problem for the Microsoft network administrators and engineers is that securing Microsoft networks is an extremely complex task. Dr Tom Shinder's ISA Server and Beyond: Real World Security Solutions for Microsoft Enterprise Networks is designed to help network administrators meet the challenge of securing Microsoft enterprise networks. This is not another Windows "security book." It is written, reviewed, and field tested by Microsoft network and security engineers who bring their real-world experiences to provide an entertaining, thought provoking, and imminently practical guide to securing Microsoft networks. Dr Tom Shinder's ISA Server and Beyond: Real World Security Solutions for Microsoft Enterprise Networks also provides scenario based, practical examples, with detailed step-by-step explanations on how to carry out the most complex and obscure security configurations on Windows NT 4.0, Windows 2000 and Windows .Net computers. The only all-encompassing book on securing Microsoft networks. · Windows NT, Windows 2000, Microsoft Internet Information Server (IIS), Microsoft Proxy Server, Microsoft Internet Security Accelerator, Microsoft Explorer are usually running simultaneously in some form on most enterprise networks. Other books deal with these components individually, but no other book provides a comprehensive solution like Dr Tom Shinder's ISA Server and Beyond: Real World Security Solutions for Microsoft Enterprise Networks Invaluable CD provides the weapons to defend your network. · The accompanying CD is packed with third party tools, utilities, and software to defend your network.

Implement Secure Access Service Edge (SASE) for secure network and application communications, exploring SASE services including SD-WAN, ZTF, and more with expert Jeremiah Ginn who helps CxO leaders achieve SASE success Key FeaturesMerge networking and security services into a single architecture to simplify network infrastructureExplore how zero trust network access (ZTNA) restricts access to provide native application segmentationFocus on a native, multitenant cloud architecture that scales dynamically with demandBook Description The SASE concept was coined by Gartner after seeing a pattern emerge in cloud and SD-WAN projects where full security integration was needed. The market behavior lately has sparked something like a "space race" for all technology manufacturers and cloud service providers to offer a "SASE" solution. The current training available in the market is minimal and manufacturer-oriented, with new services being released every few weeks. Professional architects and engineers trying to implement SASE need to take a manufacturer-neutral approach. This guide provides a foundation for understanding SASE, but it also has a lasting impact because it not only addresses the problems that existed at the time of publication, but also provides a continual learning approach to successfully lead in a market that evolves every few weeks. Technology teams need a tool that provides a model to keep up with new information as it becomes available and stay ahead of market hype. With this book, you'll learn about crucial models for SASE success in designing, building, deploying, and supporting operations to ensure the most positive user experience (UX). In addition to SASE, you'll gain insight into SD-WAN design, DevOps, zero trust, and next-generation technical education methods. What you will learnDevelop a comprehensive understanding of SASE from a market and technical perspectiveUnderstand SASE services and components included in SASE solutionsMove logically from prescriptive design to policy-based design and orchestrationUnderstand standard SASE use cases and how to integrate future componentsConvert from a legacy network design model to a secure DevOps model for future projectsUse a functional design overlay to eliminate inter-service competition for the control plane of the SASE serviceWho this book is for This book is for technology and security leaders and specifically for any CTO, CSO, CISO, or CIO looking for an executive approach to SASE for their organization. Anyone implementing SD-WAN, SASE, and SASE services for cloud, network, and security infrastructure will also find this book helpful.
