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.

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.

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.

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.

Anonymous Online Activism explores how individuals and groups leverage the dark web and encrypted platforms to challenge power structures while protecting their identities. It reveals the strategies used by digital activists to mobilize support, expose corruption, and confront powerful institutions. The book highlights the critical role of tools like Tor and VPNs in enabling anonymity, while also addressing the ethical considerations and risks associated with this form of digital dissent. It emphasizes that anonymous online activism represents a significant shift in political participation, offering both opportunities for social change and potential risks. The book delves into case studies of various activist groups, analyzing their tactics and impact, and examines the legal challenges of balancing free speech with security needs. It also discusses the future implications of emerging technologies like blockchain and AI on anonymous activism. By combining primary sources, leaked documents, and scholarly research, the book provides a nuanced understanding of the intersection of technology, politics, and anonymity. The book is structured to provide a comprehensive overview of the subject, starting with the historical roots and key technologies, progressing through case studies and legal/ethical challenges, and culminating in a discussion of future trends. This approach allows readers to grasp the complexities of anonymous online activism and engage in informed discussions about digital freedom and security.
