This book covers power systems cybersecurity. In order to enhance overall stability and security in wide-area cyber-physical power systems and defend against cyberattacks, new resilient operation, control, and protection methods are required. The cyberattack-resilient control methods improve overall cybersecurity and stability in normal and abnormal operating conditions. By contrast, cyberattack-resilient protection schemes are important to keep the secure operation of a system under the most severe contingencies and cyberattacks. The main subjects covered in the book are: 1) proposing new tolerant and cyberattack-resilient control and protection methods against cyberattacks for future power systems, 2) suggesting new methods for cyberattack detection and cybersecurity assessment, and 3) focusing on practical issues in modern power systems. Three Machine Learning (ML) methods Random Forest (RF), Logistic Regression (LR), and K-nearest neighbors (KNN) - as well as one Deep Learning (DL) method-SDAE - are dynamically compared in terms of F1 - score and accuracy. After the completion of the retraining process, the best-performing model replaces the existing one and labels the incoming data.

This is a highly practical, intensive, yet comprehensive book that will teach you to become a Google Cloud Network Engineer. The book is for anyone who would like to master the art of Google Cloud Networking. Its a perfect resource to pass the Google Professional Cloud Network Engineer Certification on the first attempt. Virtual Private Cloud (VPC) is an implemented private network on Google Cloud. The difference between a traditional and an on-premises network is that VPC is SDN. Software-Defined Network (SDN): We can see that the traditional network uses integrated software and hardware to direct traffic using routers and switches. SDN virtualizes the network by a smart controller that controls all network traffic and routers and switches that forward the traffic. Virtualizing networks can have certain advantages. With SDN, hardware management is abstracted away, which means it removes maintenance overhead and allows you to customize your services. If you do not have to worry about the number of ports on the switch, you do not have to worry about the number of virtual machines. SDN will handle that capacity.

Driving 5G Mobile Communications with Artificial Intelligence towards 6G presents current work and directions of continuously innovation and development in multimedia communications with a focus on services and users. The fifth generation of mobile wireless networks achieved the first deployment by 2020, completed the first phase of evolution in 2022, and started transition phase of 5G-Advanced toward the sixth generation. Perhaps one of the most important innovations brought by 5G is the platform-approach to connectivity, i.e., a single standard that can adapt to the heterogeneous connectivity requirements of vastly different use cases. 5G networks contain a list of different requirements, standardized technical specifications and a range of implementation options with spectral efficiency, latency, and reliability as primary performance metrics. Towards 6G, Machine Learning (ML) and Artificial Intelligence (AI) methods have recently proposed new approaches to modeling, designing, optimizing and implementing systems. They are now matured technologies that improve many research fields significantly.

Although some IoT systems are built for simple event control where a sensor signal triggers a corresponding reaction, many events are far more complex, requiring applications to interpret the event using analytical techniques to initiate proper actions. Artificial Intelligence of Things (AIoT) applies intelligence to the edge and gives devices the ability to understand the data, observe the environment around them, and decide what to do best with minimum human intervention. With the power of AI, AIoT devices are not just messengers feeding information to control centers. They have evolved into intelligent machines capable of performing self-driven analytics and acting independently. This book is a valuable resource for industry and academic researchers, scientists, engineers and advanced students in the fields of ICTs and networking, IoT, AI and machine and deep learning, Data Science, sensing, robotics, automation and smart technologies and smart environments.

Cyberspace touches practically everything and everyone when many everyday communications depend on information communication technologies. This new wave of connectivity is going beyond tablets and laptops; to connected cars and buildings; TVs and game consoles; and smart meters and traffic control. As we are critically dependent on cyberspace, it is inherently insecure and there will always be attempts to exploit weaknesses to launch cyberattacks. The cyber threat impacts the whole of our society, so everyone has a part to play in combating cybercrimes. This book is divided into five chapters, which explain how digital technology transforms societies, why cyberattacks escalate, what the challenges in cybersecurity are, how nations address global cyber risks, and how organizations defend against cyberattacks. Cybersecurity is a broad and complex topic that has a far-reaching impact on users, companies, governments, and other entities around the world. This book is divided into five chapters of discussion. These chapters, and the issues explored within them, may at first glance seem disparate, but closer examination reveals their interconnectedness.
