IPsec is Internet Protocol Security Architecture. IP is the most important and widely-used networking today. Discussions about security around this Protocol have been many and controversial. RFCs are Requests for Comments that are published on-line.

LDAP is the protocol at the heart of universally interoperable directory services applications. All major directory services products-including Novell's market-leading NDS and Microsoft's soon-to-be-released Active Directory-support LDAP, as does almost every important application for locating individuals and communicating across the Internet and other networks. Analysts predict that the network directory market will emerge as one of the most important areas in the next few years, and they agree that LDAP will play a central role in all directory solutions. This volume collects the RFCs that describe formal definitions for LDAP or document its interactions with other protocols, as well as informational documents that explain how LDAP operates.

File Transfer Protocol (FTP) was one of the first applications implemented on the Internet, and it is also one of the most fundamental. Almost all Internet hosts support it, as do almost all browsers. This volume offers exhaustive coverage of the rules governing how clients and servers communicate to enable successful data transfers via FTP. In addition to documentation of file transfer mechanics, readers will find practical instructions on many special techniques, including using file transfers for network booting and the security issues relating to file transfer over the Internet. Despite the growing acceptance of protocols specific to the Web, there remain many scenarios in which simple file transfer offers clear-cut advantages. Thus, this book is certain to prove an important source of information for years to come.

"Voice communications networks and IP data networks have almost nothing in common beyond being networks: IP networks are packet switched, while voice networks are circuit oriented. Doing voice over IP can pose real problems, as the documents included in this volume attest. Reconciling those differences is key to the ultimate success of IP telephony. Integration of voice into existing applications, such as web or email, is covered here as is the architecture for performing telephony functions and the infrastructure for providing a transport for real-time applications such as voice communications.".

"In addition to understanding the MPLS itself, you will understand how it has changed over the years (since the earliest label switching proposals were first implemented and documented within the IETF by Cisco and Toshiba); how IP and ATM interact; and why MPLS helps ease the interaction. Also included are RFCs describing the Differentiated Services (DIFFSERV) and Integrated Services (INTSERV) models, and how MPLS works within those models."--BOOK JACKET.

Address Unknown: A Guide to IPv6 offers a complete overview and introduction to the requirements and features of IP addressing within TCP/IP Version 6. IPv6 is the latest version of the core Internet communications protocol TCP/IP. The current version, IPv4, will eventually give ground to IPv6. However, network analysts project that the two versions of TCP/IP will live together for the next few years. TCP/IP addressing in IPv4 is based on a 32-bit addressing scheme. IPv6 will enable 128-bit addressing thus increasing the number of potential addresses on the Internet and avoiding the dire predictions that the Internet will run out of addressing space in the near future. This book provides a complete introduction to the TCP/IP addressing system and prepares system administrators to integrate IPv6 features into their Internet architecture. This book will be of interest to all system administrators managing an IP network, consultants working on IPv6 systems, as well as network design engineers seeking to fully understand IPv6 addressing issues. Key Features * Details the transition from TCP/IP Version 4 to IP Version 6 addressing * Includes important Internet RFCs detailing the IPv6 standard and addressing issues * Helps system administrators managing IP networks to understand the 128-bit addressing scheme and prepares them to transition from the current 32-bit address space

The Internet Host Standards are host requirements included in the IETF's STD 1, which is published as RFC 2500, Internet Official Protocol Standards. Reprinted here, these requirements are indispensable information for people working with a wide range of Internet technologies. For example, anyone wanting to build or maintain an Internet appliance will need to consult these documents to learn precisely how to make it a standards-compliant host. Likewise, anyone supporting a TCP/IP network will need to turn here for information on what capabilities are required of their systems, servers, and networks, as well as what behaviors they should-and should not-exhibit.

The first guide to tackle security architecture at the softwareengineering level Computer security has become a critical business concern, and, assuch, the responsibility of all IT professionals. In thisgroundbreaking book, a security expert with AT&T Business'srenowned Network Services organization explores system securityarchitecture from a software engineering perspective. He explainswhy strong security must be a guiding principle of the developmentprocess and identifies a common set of features found in mostsecurity products, explaining how they can and should impact thedevelopment cycle. The book also offers in-depth discussions ofsecurity technologies, cryptography, database security, applicationand operating system security, and more.

This work looks at Border Gateway Protocol and shows how it defines how backbone routing (i.e. routing on a line carrying data gathered from smaller lines) is carried out on the Internet or large intranets/extranets. BGP differs from its alternatives in that it is an industrial-strength routing protocol suitable for use in high-bandwidth backbone environments. Soon, all non-local internet traffic will be routed via BGP, and as intranets/extranets become more complet, BGP should become even more in the corporate environment.

What is IPSec? What's a VPN? Why do the need each other? Virtual Private Network (VPN) has become one of the most recognized terms in our industry, yet there continuously seems to be different impressions of what VPNs really are and can become. A Technical Guide to IPSec Virtual Private Networks provides a single point of information that represents hundreds or resources and years of experience with IPSec VPN solutions. It cuts through the complexity surrounding IPSec and the idiosyncrasies of design, implementation, operations, and security. Starting with a primer on the IP protocol suite, the book travels layer by layer through the protocols and the technologies that make VPNs possible. It includes security theory, cryptography, RAS, authentication, IKE, IPSec, encapsulation, keys, and policies. After explaining the technologies and their interrelationships, the book provides sections on implementation and product evaluation. A Technical Guide to IPSec Virtual Private Networks arms information security, network, and system engineers and administrators with the knowledge and the methodologies to design and deploy VPNs in the real world for real companies.
