A comprehensive survey of Open RAN technology and its ecosystem. In Open RAN: The Definitive Guide, a team of distinguished industry leaders deliver an authoritative guide to all four principles of the Open RAN vision: openness, virtualization, intelligence, and interoperability. Written by the industry experts currently defining the specifications, building the systems, and testing and deploying the networks, the book covers O-RAN architecture, the fronthaul interface, security, cloudification, virtualization, intelligence, certification, badging, and standardization. Virtualization and cloud have unified computing and networking. This unification can be seen in all areas of wired communications. With Open RAN (O-RAN), wireless communications will be able to take advantage of the unification as well. Wireless communications are overtaking wired communications. According to some estimates, traffic from wireless and mobile devices accounts for two-thirds of all IP traffic. However, the deployment of wireless communications is costly. The cost is mainly driven by RAN. For example, substantial increase in the number of cell sites and radio types with massive MIMO (multi-input multi-output) technology required by 5G drives RAN costs even higher. O-RAN attempts to solve this problem by disaggregating and splitting the RAN, supporting standardized interfaces that can interoperate with each other. This standardization drives multivendor radio, hardware, and software deployments with key functions implemented as virtual network functions (VNFs) and cloud-native network functions (CNFs) on vendor-neutral hardware and networks implemented in modular units.

Critical infrastructure sectors are those whose assets, systems, and networks, whether physical or virtual, are deemed so important to nations that their incapacitation or destruction would have a crippling effect on national security, national economic security, national public health or safety, or any combination of these. Each country might define their unique critical infrastructure. In this book, we compiled nine critical infrastructure sectors: Emergency Services, Energy, Finance, Food, Government, Health, Telecommunications, Transport, and Water. The continuity of services in these sectors is vital for the daily lives of societies and economies. Most cyberattacks occur in the following types: Insider attacks, social engineering, exploitation malware, extortion, and blackmail. The rising interconnectedness of vital infrastructures via IoT technologies, as well as the rise of coordinated cyberattacks worldwide, is a concerning issue. There are different types of attacks. While some of them are simultaneously IoT-based attacks, some of them are not. Therefore, IoT causes extra vulnerability to systems. Since the IoT is the evolution of Machine-to-Machine communication, and it uses embedded electronics to link everyday things to the Internet, with minimum human effort, these linked items can exchange and gather data. Digital systems can record, monitor, and alter each interaction between linked items in today’s hyper-connected environment. Although IoT is a beneficial breakthrough and has become widespread, it is vulnerable to cyberattacks.

A comprehensive guide to the most recent developments in blockchains in theoretical and industrial perspectives. Originally introduced as a method to keep track of Bitcoin transactions over a peer-to-peer network, blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography into a chain held in public databases. The use of this technology has grown since its cryptocurrency creation and now store three types of information: 1) transactions, including the date, time, and value of purchases; 2) records of participates in transactions; and 3) unique code known as a “hash” that distinguishes one block from another. A single block on the blockchain can hold 1 MB of data, or potentially thousands of transactions – this then can allow for hundreds of thousands of transactions to be recorded as each block can join the state-of-the-art blockchain. Blockchains provides a detailed overview of the latest and most innovative concepts, techniques, and applications related to the developing blockchain. Aimed at novices and experts on the subject, the book focuses on blockchain technologies, integrated systems, and use cases, specifically by looking at three major technical areas: blockchain platforms and distributed database technologies, consensus and fault tolerance, and Blockchain as a Service (BaaS).

The book addresses the challenges in designing blockchain-based secured solutions for Industry 4.0 applications using artificial intelligence. It further provides a comparative analysis of various advanced security approaches such as edge computing, cybersecurity, and cloud computing in the realm of information technology. Industry 4.0 has significantly exploded as a result of using the Internet of Things’ (IoT) recent large- scale growth, which executes the intricate data analysis of confidential material that must be safeguarded against cybersecurity attacks. In a number of industries, including home automation, healthcare, electricity, agriculture, automation, and industrial processes, cybersecurity threats have rapidly increased. IoT device sensors produce a lot of data due to their broad range of services, which necessitates authori- sation, security, and privacy. In the past, conventional frameworks and pro- cedures were employed to guarantee IoT security. But over time, the use of various Artificial Intelligence (AI) techniques for spotting cybersecurity breaches has grown in favour .

Following the success of Linux Basics for Hackers, OccupytheWeb does what he did for Linux to Networks. Networks of all types, including TCP/IP, Bluetooth Networks, Car Networks, W-iFi Networks, Radio Frequency Networks, SCADA/ICS Networks, and more. In his inimitable style, Master OTW makes the seemingly complex, simple. This book is designed for beginner to intermediate cybersecurity professionals. It begins with the basics of networks and networking, examines network analysis with Wireshark and tcpdump, offers one of the most complete and in-depth analyses of Wi-Fi and Bluetooth networks, then progresses through the various protocols such as DNS, ARP, SMTP, and others. The reader will be led through the building of those applications in Linux, such as an EXIM server for email or a BIND server for DNS. Then OTW leads the reader through the major vulnerabilities of that protocol/application. We will start with basic networking and TCP/IP concepts and then progress to tools for analyzing network packets and protocols.
