With the constant stream of emails, social networks, and online bank accounts, technology has become a pervasive part of our everyday lives, making the security of these information systems an essential requirement for both users and service providers. Architectures and Protocols for Secure Information Technology Infrastructures investigates different protocols and architectures that can be used to design, create, and develop security infrastructures by highlighting recent advances, trends, and contributions to the building blocks for solving security issues. This book is essential for researchers, engineers, and professionals interested in exploring recent advances in ICT security.

The Internet of Things (IoT) refers to the network of interconnected physical devices, vehicles, appliances, and other objects embedded with sensors, software, and network connectivity. These devices can collect and exchange data, enabling them to interact with each other and with their environment. The significance of IoT lies in its ability to enhance efficiency, provide valuable insights through data analytics, and improve automation in various sectors, ranging from healthcare and agriculture to smart cities and industrial processes. The use of IoT devices has proliferated across diverse sectors, including healthcare, agriculture, transportation, manufacturing, and smart homes. These devices offer benefits such as real-time monitoring, predictive maintenance, and improved decision-making. However, the widespread deployment of IoT devices also raises security concerns due to the interconnected nature of these systems. The interconnected nature of IoT introduces security challenges as it expands the attack surface. Vulnerabilities in one device can potentially compromise the entire network, leading to data breaches, unauthorized access, and disruptions to critical services. Common vulnerabilities in IoT devices include insecure firmware, weak authentication mechanisms, insufficient encryption, and susceptibility to physical tampering. These vulnerabilities can be exploited by attackers to gain unauthorized access, manipulate data, or launch attacks on other devices. Insecure firmware can be a major security risk, as it may contain vulnerabilities that can be exploited by attackers. Weak authentication mechanisms can lead to unauthorized access, while the lack of encryption can expose sensitive data to interception and manipulation. Real-world examples of IoT security breaches include incidents where attackers compromised smart home devices, industrial control systems, or healthcare devices to gain unauthorized access, manipulate data, or disrupt operations. These breaches highlight the need for robust security measures in IoT deployments. Securing IoT networks is challenging due to the diverse nature of devices, varying communication protocols, and the sheer volume of data generated. Additionally, many IoT devices have resource constraints, making it difficult to implement robust security measures. Firewalls, intrusion detection systems (IDS), and network segmentation play crucial roles in IoT security. Firewalls help filter and monitor traffic, IDS detects unusual behavior, and network segmentation limits the impact of a breach by isolating compromised devices from the rest of the network. Implementing strong encryption protocols, ensuring secure key management, and regularly updating device firmware are key best practices for safeguarding communication between IoT devices. Additionally, using secure communication protocols such as TLS/SSL enhances the integrity and confidentiality of data. Data generated by IoT devices often includes sensitive information about individuals, their habits, and their environments. Protecting this data is crucial to maintain user privacy and prevent unauthorized access.

Security and privacy protection within computer networks can be a challenge. By examining the current problems and challenges this domain is facing, more efficient strategies can be established to safeguard personal information against invasive pressures. Security and Privacy in Smart Sensor Networks is a critical scholarly resource that examines recent developments and emerging trends in smart sensor security and privacy by providing new models, practical solutions, and technological advances related to security. Featuring coverage on a broad range of topics such as cloud security, encryption, and intrusion detection systems, this book is geared towards academicians, engineers, IT specialists, researchers, and students seeking current research on authentication and intrusion detection.

From the Foreword: "This book lays out much of what we’ve learned at AT&T about SDN and NFV. Some of the smartest network experts in the industry have drawn a map to help you navigate this journey. Their goal isn’t to predict the future but to help you design and build a network that will be ready for whatever that future holds. Because if there’s one thing the last decade has taught us, it’s that network demand will always exceed expectations. This book will help you get ready." —Randall Stephenson, Chairman, CEO, and President of AT&T "Software is changing the world, and networks too. In this in-depth book, AT&T's top networking experts discuss how they're moving software-defined networking from concept to practice, and why it's a business imperative to do this rapidly." —Urs Hölzle, SVP Cloud Infrastructure, Google "Telecom operators face a continuous challenge for more agility to serve their customers with a better customer experience and a lower cost. This book is a very inspiring and vivid testimony of the huge transformation this means, not only for the networks but for the entire companies, and how AT&T is leading it. It provides a lot of very deep insights about the technical challenges telecom engineers are facing today. Beyond AT&T, I’m sure this book will be extremely helpful to the whole industry." —Alain Maloberti, Group Chief Network Officer, Orange Labs Networks "This new book should be read by any organization faced with a future driven by a "shift to software." It is a holistic view of how AT&T has transformed its core infrastructure from hardware based to largely software based to lower costs and speed innovation. To do so, AT&T had to redefine their technology supply chain, retrain their workforce, and move toward open source user-driven innovation; all while managing one of the biggest networks in the world. It is an amazing feat that will put AT&T in a leading position for years to come." —Jim Zemlin, Executive Director, The Linux Foundation This book is based on the lessons learned from AT&T’s software transformation journey starting in 2012 when rampant traffic growth necessitated a change in network architecture and design. Using new technologies such as NFV, SDN, Cloud, and Big Data, AT&T’s engineers outlined and implemented a radical network transformation program that dramatically reduced capital and operating expenditures. This book describes the transformation in substantial detail. The subject matter is of great interest to telecom professionals worldwide, as well as academic researchers looking to apply the latest techniques in computer science to solving telecom’s big problems around scalability, resilience, and survivability.
