This completely revised and expanded second edition of SSL and TLS: Theory and Practice provides an overview and a comprehensive discussion of the Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Datagram TLS (DTLS) protocols that are omnipresent in today's e-commerce and e-business applications and respective security solutions. It provides complete details on the theory and practice of the protocols, offering readers a solid understanding of their design principles and modes of operation. Updates to this edition include coverage of the recent attacks against the protocols, newly specified extensions and firewall traversal, as well as recent developments related to public key certificates and respective infrastructures. This book targets software developers, security professionals, consultants, protocol designers, and chief security officers who will gain insight and perspective on the many details of the SSL, TLS, and DTLS protocols, such as cipher suites, certificate management, and alert messages. The book also comprehensively discusses the advantages and disadvantages of the protocols compared to other Internet security protocols and provides the details necessary to correctly implement the protocols while saving time on the security practitioner's side.

Now in its Third Edition, this completely revised and updated reference provides a thorough and comprehensive introduction into the SSL, TLS, and DTLS protocols, explaining all the details and technical subtleties and showing how the current design helps mitigate the attacks that have made press headlines in the past. The book tells the complete story of TLS, from its earliest incarnation (SSL 1.0 in 1994), all the way up to and including TLS 1.3. Detailed descriptions of each protocol version give you a full understanding of why the protocol looked like it did, and why it now looks like it does. You will get a clear, detailed introduction to TLS 1.3 and understand the broader context of how TLS works with firewall and network middleboxes, as well the key topic of public infrastructures and their role in securing TLS. You will also find similar details on DTLS, a close sibling of TLS that is designed to operate over UDP instead of TCP. The book helps you fully understand the rationale behind the design of the SSL, TLS, and DTLS protocols and all of its extensions. It also gives you an in-depth and accessible breakdown of the many vulnerabilities in earlier versions of TLS, thereby more fully equipping you to properly configure and use the protocols in the field and protect against specific (network-based) attacks. With its thorough discussion of widely deployed network security technology, coupled with its practical applications you can utilize today, this is a must-have book for network security practitioners and software/web application developers at all levels.

This exciting resource introduces the core technologies that are used for Internet messaging. The book explains how Signal protocol, the cryptographic protocol that currently dominates the field of end to end encryption (E2EE) messaging, is implemented and addresses privacy issues related to E2EE messengers. The Signal protocol and its application in WhatsApp is explored in depth, as well as the different E2EE messengers that have been made available in the last decade are also presented, including SnapChat. It addresses the notion of self-destructing messages (as originally introduced by SnapChat) and the use of metadata to perform traffic analysis. A comprehensive treatment of the underpinnings of E2EE messengers, including Pretty Good Privacy (PGP) and OpenPGP as well as Secure/Multipurpose Internet Mail Extensions (S/MIME) is given to explain the roots and origins of secure messaging, as well as the evolutionary improvements to PGP/OpenPGP and S/MIME that have been proposed in the past. In addition to the conventional approaches to secure messaging, it explains the modern approaches messengers like Signal are based on. The book helps technical professionals to understand secure and E2EE messaging on the Internet, and to put the different approaches and solutions into perspective.
