End-to-End Encrypted Messaging by Rolf Oppliger Pdf

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.

Secure Messaging Scenarios with WebSphere MQ by T.Rob Wyatt,Glenn Baddeley,Neil Casey,Long Nguyen,Jørgen H. Pedersen,Morten Sætra,IBM Redbooks Pdf

The differences between well-designed security and poorly designed security are not always readily apparent. Poorly designed systems give the appearance of being secure but can over-authorize users or allow access to non-users in subtle ways. The problem is that poorly designed security gives a false sense of confidence. In some ways, it is better to knowingly have no security than to have inadequate security believing it to be stronger than it actually is. But how do you tell the difference? Although it is not rocket science, designing and implementing strong security requires strong foundational skills, some examples to build on, and the capacity to devise new solutions in response to novel challenges. This IBM® Redbooks® publication addresses itself to the first two of these requirements. This book is intended primarily for security specialists and IBM WebSphere® MQ administrators that are responsible for securing WebSphere MQ networks but other stakeholders should find the information useful as well. Chapters 1 through 6 provide a foundational background for WebSphere MQ security. These chapters take a holistic approach positioning WebSphere MQ in the context of a larger system of security controls including those of adjacent platforms' technologies as well as human processes. This approach seeks to eliminate the simplistic model of security as an island, replacing it instead with the model of security as an interconnected and living system. The intended audience for these chapters includes all stakeholders in the messaging system from architects and designers to developers and operations. Chapters 7 and 8 provide technical background to assist in preparing and configuring the scenarios and chapters 9 through 14 are the scenarios themselves. These chapters provide fully realized example configurations. One of the requirements for any scenario to be included was that it must first be successfully implemented in the team's lab environment. In addition, the advice provided is the cumulative result of years of participation in the online community by the authors and reflect real-world practices adapted for the latest security features in WebSphere MQ V7.1 and WebSphere MQ V7.5. Although these chapters are written with WebSphere MQ administrators in mind, developers, project leaders, operations staff, and architects are all stakeholders who will find the configurations and topologies described here useful. The third requirement mentioned in the opening paragraph was the capacity to devise new solutions in response to novel challenges. The only constant in the security field is that the technology is always changing. Although this book provides some configurations in a checklist format, these should be considered a snapshot at a point in time. It will be up to you as the security designer and implementor to stay current with security news for the products you work with and integrate fixes, patches, or new solutions as the state of the art evolves.

The Effect of Encryption on Lawful Access to Communications and Data by James A. Lewis,Denise E. Zheng,William A. Carter Pdf

The Internet has become central to global economic activity, politics, and security, and the security environment has changed recently, as we face much more aggressive state actors in espionage. Terrorists and criminals find creative ways to leverage the latest technologies to evade security and privacy protections, but there may be technical and policy solutions that can balance national security and public safety with protection of privacy, civil liberties, and a functioning global Internet ecosystem.

Introduction to WhatsApp by Gilad James, PhD Pdf

WhatsApp is a popular mobile application that was founded in 2009 by Jan Koum and Brian Acton. The app allows users to send text messages and voice messages, make voice and video calls, share images, documents, user locations, and other media. In addition to personal messaging, WhatsApp also offers a range of features for businesses, including WhatsApp Business, which allows small businesses to communicate with their customers and share updates over the app. WhatsApp has grown to become one of the most widely used messaging apps in the world, with over 2 billion active users across 180 countries. WhatsApp makes use of end-to-end encryption to ensure that only the sender and recipient of a message can access its contents. The company has been praised for its commitment to user privacy, although it has also faced scrutiny over its handling of false information and its role in facilitating political unrest. Nevertheless, the app remains a vital tool for communication and connection, particularly in countries where other messaging apps are restricted or banned. Its continued popularity is a testament to the users' trust in its security and reliability.

Information Security Essentials by Susan E. McGregor Pdf

As technological and legal changes have hollowed out the protections that reporters and news organizations have depended upon for decades, information security concerns facing journalists as they report, produce, and disseminate the news have only intensified. From source prosecutions to physical attacks and online harassment, the last two decades have seen a dramatic increase in the risks faced by journalists at all levels even as the media industry confronts drastic cutbacks in budgets and staff. As a result, few professional or aspiring journalists have a comprehensive understanding of what is required to keep their sources, stories, colleagues, and reputations safe. This book is an essential guide to protecting news writers, sources, and organizations in the digital era. Susan E. McGregor provides a systematic understanding of the key technical, legal, and conceptual issues that anyone teaching, studying, or practicing journalism should know. Bringing together expert insights from both leading academics and security professionals who work at and with news organizations from BuzzFeed to the Associated Press, she lays out key principles and approaches for building information security into journalistic practice. McGregor draws on firsthand experience as a Wall Street Journal staffer, followed by a decade of researching, testing, and developing information security tools and practices. Filled with practical but evergreen advice that can enhance the security and efficacy of everything from daily beat reporting to long-term investigative projects, Information Security Essentials is a vital tool for journalists at all levels. * Please note that older print versions of this book refer to Reuters' Gina Chua by her previous name. This is being corrected in forthcoming print and digital editions.
