In the context of information security, social engineering is the manipulation of people into performing actions or divulging information for the purpose of gathering, defrauding, or gaining unauthorized system access. While some of the most common forms of social engineering involve telephone or social networks where criminals pose as employees of targeted organizations, phishing accounts for 96% of all successful cyber-attacks. Governments and private organizations have responded through various means such as training employees, executing internal vulnerability assessments, and ad campaigns. Despite all these efforts, phishing continues to provide the primary cyber-attack vector for nefarious entities.Phishing attacks continue to escalate, with over 300,000 reported incidents in the US alone last year. This book provides an in-depth look at the anatomy of modern phishing threats and how they are evolving with AI technologies.

A consensus mechanism is the core component of a blockchain network, which ensures that every participant agrees on the state of the network in trustless environments. Until now, current blockchain networks have been using the proof-of-work (PoW) consensus mechanism, which has serious limitations such as huge energy consumption, low transaction processing capabilities, and centralization and scalability issues. To overcome these problems, a new consensus mechanism entitled proof-of-stake (PoS) has been developed. PoS has many advantages, including negligible energy consumption and very low consensus delay. Ethereum (the largest decentralized global software platform to create secured digital technology powered by blockchain technology and the blockchain of choice globally for all developers and enterprises) has just switched from PoW to PoS. As a result, this mechanism is expected to become a cutting-edge technology for future blockchain networks.This book provides a comprehensive discussion of the PoS consensus mechanism for blockchain networks. Starting with an overview of blockchain technology and consensus mechanisms, including basic concepts and network architecture, the book provides a review of the PoS consensus mechanism, including PoS consensus security and PoS performance and scalability issues.Proof-of-Stake for Blockchain Networks: Fundamentals, challenges and approaches is a valuable resource for researchers, engineers, and postgraduate students who are interested in advanced PoS consensus mechanisms, as well as developers and entrepreneurs who are interested in developing applications using the PoS consensus mechanism.

New approaches in federated learning and split learning have the potential to significantly improve ubiquitous intelligence in internet of things (IoT) applications. In split federated learning, the machine learning model is divided into smaller network segments, with each segment trained independently on a server using distributed local client data.The split learning method mitigates two fundamental drawbacks of federated learning: affordability, and privacy and security. When running machine learning computation on devices with limited resources, assigning only a portion of the network to train at the client-side minimizes the processing burden, compared to running a complete network as in federated learning. In addition, neither client nor server has full access to the other, which is more secure.This book reviews cutting edge technologies and advanced research in split federated learning. Coverage includes approaches to realizing and evaluating the effectiveness and advantages of federated learning and split-fed learning, the role of this technology in advancing and securing IoTs, advanced research on emerging AI models for preserving the privacy of the data owned by the clients, and the analysis and development of AI mechanisms in IoT architectures and applications.
