Название: Ransomware and Data Extortion: The Shifting Threat Landscape Автор: Ryan Golden, Anthony M. Freed Издательство: O’Reilly Media, Inc. Год: 2024-04-19 Язык: английский Формат: pdf, epub Размер: 10.1 MB
Ransomware poses an existential threat to organizations of all sizes in any vertical. These attacks are extremely lucrative, with ransom demands and recovery costs bleeding victim organizations out of millions of dollars. This book provides an overview of the ransomware economy, including the threat that this complex attack ecosystem poses to organizations, and reveals how you can best prepare to be resilient in the face of this threat and remain operational. Ransomware is a major threat to businesses and organizations of all kinds. Ransomware and data extortion attacks are not only disruptive to business operations but also costly to resolve. They spur regulatory actions and civil litigation, including class action lawsuits against victim organizations, and more recently have even resulted in criminal charges being lodged against company officers. A dedicated anti-ransomware solution utilizes Artificial Intelligence (AI) and Machine Learning (ML) with behavioral analytics to identify and stop polymorphic and repacked variants of ransomware that EPP, EDR, and XDR continue to miss. This is because AI/ML endpoint protection models were trained on characteristics that all malware share, including a subset of ransomware.
Название: 5G NR Modelling in MATLAB: Network Architecture, Protocols, and Physical Layer Автор: Tulsi Pawan Fowdur, Madhavsingh Indoonundon, Dragorad A. Milovanovic Издательство: CRC Press Год: 2025 Страниц: 450 Язык: английский Формат: pdf (true) Размер: 48.8 MB
5G is the fifth generation of cellular technology. It is designed to increase speed, reduce latency, and improve the flexibility of wireless services. 5G New Radio (NR) is the enabler of three key service classes: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low Latency Communications (URLLC), and Massive Machine-Type Communications (mMTC). The 5G network is expected to deliver a wide range of services that includes eMBB, mMTC, and URLLC. To realize such a diverse set of requirements, the 5G network has evolved as a multilayer network that uses various technological advances to offer an extensive range of wireless services. Several technologies, such as software-defined networking, network function virtualization, edge computing, cloud computing, and small cells, are being integrated into the 5G networks to fulfill the need for diverse requirements. This book provides a detailed description of the fundamental aspects of 5G. It gives an in-depth coverage of the network architecture of 5G by considering both the network reference point architecture and the service-based architecture. The MathWorks introduced MATLAB’s 5G Toolbox which provides standard-compliant functions and examples for the simulation of the 5G environment. In this book, functions from the toolbox were used to build the 5G NR end-to-end physical layer model for Packet Data Shared Channel (PDSCH) processing and to calculate the PDSCH throughput, Bit Error Rate (BER), and Block Error Rate (BLER). Moreover, MATLAB models of each block have been used to simulate a complete 5G downlink system.

Название: Tor: From the Dark Web to the Future of Privacy Автор: Ben Collier Издательство: The MIT Press Год: 2024 Страниц: 243 Язык: английский Формат: pdf (true), epub (true) Размер: 10.1 MB
A biography of Tor—a cultural and technological history of power, privacy, and global politics at the internet's core. Tor, one of the most important and misunderstood technologies of the digital age, is best known as the infrastructure underpinning the so-called Dark Web. But the real “dark web,” when it comes to Tor, is the hidden history brought to light in this book: where this complex and contested infrastructure came from, why it exists, and how it connects with global power in intricate and intimate ways. In Tor: From the Dark Web to the Future of Privacy, Ben Collier has written, in essence, a biography of Tor—a cultural and technological history of power, privacy, politics, and empire in the deepest reaches of the internet. Tor—still known to most as the Dark Web or Dark Net—is not an easy subject to research. It exists on a bizarre terrain, simultaneously in the living rooms of lovely nerds, in the nightmares of police officers, in the small spaces of everyday digital life, and in the corridors of global power. It is a thin and brittle network stretched across the globe like a glass spiderweb and at the same time a profound challenge to the most powerful spy agencies in the world. Most users access Tor in the form of a rather innocuous web browser—much like Chrome, Safari, or Firefox—that rapidly clicks and whirrs through a pleasing set of additional messages before it starts up, giving it a slightly hacker-film feel. Once this is finished and the connection to the Tor network is confirmed, the user can simply browse the internet as normal.
Название: Self-Powered AIoT Systems Автор: Niranjan N. Chiplunkar, K.V.S.S.S.S. Sairam, Rathishchandra R. Gatti Издательство: Apple Academic Press, CRC Press Год: 2025 Страниц: 357 Язык: английский Формат: pdf (true) Размер: 20.6 MB
This new volume focuses on design principles for building self-powered AIoT (artificial intelligence of things) applications and their subsequent deployment. The book introduces the futuristic concepts of AIoT by incorporating self-powered systems, firstly by informing the reader of current AI/ML techniques and IoT technologies and then showing the path towards convergence of AI/IoT towards AIoT. The book also explains the many possible diverse applications of AIoT. The combination of IoT for sensing and aggregation of data from the surroundings and AI for analysis and decision-making will expand cyber-physical intelligence towards achieving complete autonomy. However, as the deployment of sensors becomes increasingly ubiquitous, there will be a massive amount of sensor data aggregation and analyses for autonomous decision-making capabilities of AIoT products. This calls for substantial research and product development in self-powered technologies such as energy harvesters, supercapacitors, energy storage devices for energy generation, and energy-efficient technologies such as ultra-low power (ULP) microcontrollers, ULP microprocessors, and ULP smart sensors and actuators. This volume helps to fill that gap. The volume presents research and product development towards structured convergence of self-powered systems, leading to pragmatic R&D deliverables for new products and services. The book is the first of its kind on reporting how the current AI and IoT are progressing toward the vision of AIoT.

Some principles will directly correlate with all three domains; some will be more peculiar to each domain. Zero Trust is a great example of a methodology that should extend throughout the entire digital estate of your enterprise and serve as an integrated security philosophy and end-to-end strategy. When designing a security solution using Microsoft technologies, it is important to consider the entire portfolio of options to have a complete approach for resources in Azure, Microsoft 365, and on-premises.
Название: Data-Centric Security in Software Defined Networks (SDN) Автор: Marek Amanowicz, Sebastian Szwaczyk, Konrad Wrona Издательство: Springer Год: 2024 Страниц: 133 Язык: английский Формат: pdf (true), epub Размер: 10.1 MB
The book focuses on applying the data-centric security (DCS) concept and leveraging the unique capabilities of software-defined networks (SDN) to improve the security and resilience of corporate and government information systems used to process critical information and implement business processes requiring special protection. As organisations increasingly rely on information technology, cyber threats to data and infrastructure can significantly affect their operations and adversely impact critical business processes. Appropriate authentication, authorisation, monitoring, and response measures must be implemented within the perimeter of the system to protect against adversaries. However, sophisticated attackers can compromise the perimeter defences and even remain in the system for a prolonged time without the owner being aware of these facts. Therefore, new security paradigms such as Zero Trust and DCS aimto provide defence under the assumption that the boundary protections will be breached.
Название: Security Framework for The Internet of Things Applications Автор: Salma Abdalla Hamad, Quan Z. Sheng, Wei Emma Zhang Издательство: CRC Press Год: 2024 Страниц: 153 Язык: английский Формат: pdf (true) Размер: 11.9 MB
The text highlights a comprehensive survey that focuses on all security aspects and challenges facing the Internet of Things systems, including outsourcing techniques for partial computations on edge or cloud while presenting case studies to map security challenges. It further covers three security aspects including Internet of Things device identification and authentication, network traffic intrusion detection, and executable malware files detection. Industrial Internal of Things (IIoT) products and services collect a large amount of data including those related to users. This collected data are stored either locally on the smart devices or in the cloud. Although Internet of Things (IoT) expansions promise enormous benefits in productivity and efficiency, these devices often lack the security requirements we have become used to in the domain of desktops and server computing. Therefore, processing such large-scale IoT data can also lead to many security issues such as intrusion attacks, data leakage, user privacy, and traceability. This book presents substantial contributions to research on building a scalable, real-time IoT security framework. This book provides several novel strategies for identifying and authenticating devices, detecting network-known and zero-day attacks against IoT devices, and detecting malware executables targeting IoT and embedded systems. In this book, we consider three security aspects: IoT device identification and authentication, network traffic intrusion detection, and executable malware file detection.
