A modern SD-WAN solution offers automated and secure device onboarding as well well as Centralized Management and Control Plane. It also supports multiple VPNs over a common underlay network as well as highly secure Direct Cloud/Internet Access and Application-Aware Routing. I wrote this book primarily for those of you who want to learn the basics of a Cisco SD-WAN solution. The first two chapters explain how to set up your local test environment. You will learn how to install certificates to vBond, vManage, vSmart, and vEdge and how to set up underlay and Out-of-Band management network connections. Chapter three introduces a centralized control plane with the Overlay Management Protocol (OMP) running between vEdges and vSmart. After reading this chapter, you should be familiar with how overlay tunnels between vEdges are built by using TLOC routes. Besides, you learn how Sevice VPN routing information is advertised by using OMP routes.

Data is the most important commodity, which is why data protection has become a global priority. Data breaches and security flaws can jeopardize the global economy. Organizations face a greater risk of failing to achieve strategy and business goals as cyber threat behavior grows in frequency, sophistication, and destructiveness. A breach can result in data loss, business interruption, brand and reputation harm, as well as regulatory and legal consequences. A company needs a well-thought-out cybersecurity strategy to secure its critical infrastructure and information systems in order to overcome these challenges. Chapter 2 talks about the role of Artificial Intelligence (AI) on cybersecurity and its control. Nowadays, cyber security is paramount in all aspects of life, particularly in digital technology. Stories of Artificial Intelligence and data breaches, ID theft, cracking the security code, operating machines with remote sensors, and other such incidents abound, affecting millions of individuals and organizations. The problems in developing appropriate controls and processes and applying them with utmost precision to combat cyber-attacks & crimes have always been unending. With recent advances in Artificial Intelligence, the ever-increasing danger of cyber-attacks and crimes has grown tremendously.

Make security a priority on your team. Every organization needs a strong security program. One recent study estimated that a hacker attack occurs somewhere every 37 seconds. Since security programs are only as effective as a team’s willingness to follow their rules and protocols, it’s increasingly necessary to have not just a widely accessible gold standard of security, but also a practical plan for rolling it out and getting others on board with following it. Security Awareness For Dummies gives you the blueprint for implementing this sort of holistic and hyper-secure program in your organization. Cyberattacks aren’t going away anytime soon: get this smart, friendly guide on how to get a workgroup on board with their role in security and save your organization big money in the long run.

This book provides detailed descriptions of downlink non-orthogonal multiple transmissions and uplink non-orthogonal multiple access (NOMA) from the aspects of majorly used 5G new radio scenarios and system performance. For the downlink, the discussion focuses on the candidate schemes in 3GPP standards which are not only applicable to unicast services but also to broadcast/multicast scenarios. For the uplink, the main target scenario is massive machine-type communications where grant-free transmission can reduce signaling overhead, power consumption of devices and access delays. The design principles of several uplink NOMA schemes are discussed in-depth, together with the analysis of their performances and receiver complexities. In the communications industry, greater interest is seen in the innovative upgrade of the systems by integrating advanced wireless and network technologies of 5G.

Energy Efficient Spectrum Resources Usage in WPANs: IEEE 82.15.4 MAC Sub-layer ProtocolsНазвание: Energy Efficient Spectrum Resources Usage in WPANs: IEEE 82.15.4 MAC Sub-layer Protocols

Wireless Sensor Networks (WSNs) and the Internet of Things (IoT) are facing tremendous advances both in terms of energy-efficiency as well as in the number of available applications. Consequently, there are open challenges that need to be tackled for the future generation of WSNs, and this book gives answers to some of the important questions that need to be answered. After giving an overview of the WSN protocols and IEEE 802.15.4 standard, this book proposes IEEE 802.15.4 Medium Access Control (MAC) sub-layer performance enhancements by employing not only RTS/CTS combined with packet concatenation but also scheduled channel poling (MC-SCP). Results have shown that the use of the RTS/CTS mechanism improves channel efficiency by decreasing the deferral time before transmitting a data packet. Furthermore, the Sensor Block Acknowledgment MAC (SBACK-MAC) protocol enables more efficiency as it allows the aggregation of several acknowledgement responses in one special Block Acknowledgment (BACK) Response packet.
