Introduction to Network Security Posted: 30 Mar 2009 02:49 AM PDT Introduction to Network Security Product Description In today’s online, connected world where computers outsell TVs and e-commerce sales surpass those of “brick-and-mortar” stores, secure network environments are a necessity. Weaknesses within networks have led to the rapid growth of identity theft and computer virus outbreaks, so the demand for skilled and aspiring system administrators who can protect networks is growing. If you are tasked with protecting your networks from these threats, or are studying security, Introduction to Network Security will help you increase your understanding of potential threats, learn how to apply practical mitigation options, and react to attacks quickly. The book teaches you the skills and knowledge you need to design, develop, implement, analyze, and maintain networks and network protocols. It explains how these systems currently operate and the limitations that lead to security weaknesses. All of the fundamental issues needed to understand network security, including the definition of security terms, security ethics, the OSI network model, and cryptography for networks are covered in detail. The book focuses on the seven layers in the OSI network model by describing each overall layer, its security role, common vulnerabilities, and mitigation techniques. The discussion of each layer is followed by explicit examples of common protocols within the layer and their respective security issues. The last part of the book explores the common risks for secure network design and development, including the impact of modularity on security and a summary of the general security issues. If you are new to network security, a general IT administrator, or a student, this is a must-have a resource to help ensure that you have the skills and knowledge required to protect your networks! About the Author Neal Krawetz (Fort Collins, CO) operates Hacker Factor Solutions and holds a Ph.D. in Computer Science from Texas A&M University.

Enterprise Web Services Security Posted: 30 Mar 2009 02:49 AM PDT Enterprise Web Services Security Product Description Learn to Protect Your Assets and Prevent Attacks! The use of Web Services for Business-to-Business (B2B) and Business-to-Consumer (B2C) transactions has created risks that expose critical assets to increasingly greater threats. Enterprise Web Services Security provides the information developers, application architects, and security professionals need to build security policies and strategies from the ground up in a Web Services environment. Most security books focus on computer or network security in isolation, relegating the other areas to overview chapters or appendices. A single-system view of security, however, is not adequate to describe a distributed Web Services-based environment as it causes the developer to have to piece together material from several resources in order to create secure Web sites and services. This book takes a holistic approach that mirrors the perspective developers need to take regardless of whether they are planning and implementing the security mechanisms for a Web Service, a Web site, or an enterprise. It details how to secure critical components such as workstations, servers, and networks, the goals behind an enterprise's security policies, the policies an organization should have in place, and how to communicate those policies using WS-Policy Framework and WS-Security Policy. Various threats and attacks are also covered, as well as the identity management, authentication, authorization, access control, confidentiality, and integrity mechanisms needed to protect messages and transactions. Enterprise Web Services Security is the one book developers need to make all their security mechanisms work successfully to thwart attacks and protect assets. Key Features! * Teaches developers, application architects, and security professionals how to build security policies and select appropriate security mechanisms and strategies in a Web Services environment * Covers the underlying protocols and technologies that form the Internet (TCP/IP, HTTP) and Web Services (XML, SOAP, WSDL, UDDI), and the major XML and Web Services standards that are the basis of implementing security in a Web Services environment * Teaches how to implement and communicate security mechanisms using WSSecurity, XML Encryption, XML Signature, SAML, and XACML * Explores the importance of auditing at both the server and network level and how to create trust relationships and domains * Explains how to implement security policies and mechanisms in both J2EE and .NET * Includes a companion CD-ROM with all of the references, source code, and figures from the book ON THE CD (see Appendix B for more details) * Code Samples: Contains all of the XML listings from the book * References: Provides hyperlinks for all the reference materials used in the book * Work sheet: Includes a work sheet for deploying a Web Services system as described in the book * Figures: Includes all of the fi gures from the book by chapter SYSTEM REQUIREMENTS: Any Windows, Macintosh, or UNIX system that allows reading this CDROM and has the ability to view and display XML, text, PDF, and Microsoft Office files. download

Innovative Cryptography Posted: 30 Mar 2009 02:47 AM PDT Innovative Cryptography Product Description Innovative Cryptography, Second Edition provides a cutting-edge evaluation and review of current findings in the area of cryptography and explores how to implement these new techniques efficiently. It covers current cryptographic problems and suggests practical solutions. The book also discusses the role of symmetric ciphers and symmetric block ciphers, and details the need for fast symmetric ciphers for hardware (DES), software (RC5, Blowfish), and universal (AES, RC6, Twofish, IDEA, GOST) implementations. In addition, the book covers the issues surrounding the development and design of software-oriented ciphers, including ciphers based on the algorithm formed depending on the secret key. Some specific issues related to the cryptographic strength of ciphers with the flexible algorithm of data transformation are considered, and a combinational probabilistic model is suggested for obtaining minimal evaluations of the software ciphers being considered. A highly promising new command suggested to be used in universal processors is also discussed. This command executes controlled bit permutation, and is expected to sharply increase the performance of cryptographic algorithms including bit permutations of arbitrary type. Innovative Cryptography, Second Edition is written for anyone involved in the development of cryptopgraphic tools, including engineers, researches, programmers, and IT security professionals.
