Hands-On Network Programming with C

By: Lewis Van Winkle

Overview of this book

Network programming enables processes to communicate with each other over a computer network, but it is a complex task that requires programming with multiple libraries and protocols. With its support for third-party libraries and structured documentation, C is an ideal language to write network programs. Complete with step-by-step explanations of essential concepts and practical examples, this C network programming book begins with the fundamentals of Internet Protocol, TCP, and UDP. You’ll explore client-server and peer-to-peer models for information sharing and connectivity with remote computers. The book will also cover HTTP and HTTPS for communicating between your browser and website, and delve into hostname resolution with DNS, which is crucial to the functioning of the modern web. As you advance, you’ll gain insights into asynchronous socket programming and streams, and explore debugging and error handling. Finally, you’ll study network monitoring and implement security best practices. By the end of this book, you’ll have experience of working with client-server applications and be able to implement new network programs in C. The code in this book is compatible with the older C99 version as well as the latest C18 and C++17 standards. You’ll work with robust, reliable, and secure code that is portable across operating systems, including Winsock sockets for Windows and POSIX sockets for Linux and macOS.

Ethics of IoT

Much criticism has been leveled at the IoT concept regarding privacy, security, and other ethical concerns. This isn't surprising, given these devices' pervasive presence in our lives.

Most IoT devices work in conjunction with a central server. This server gets essentially all of the collected data from the IoT devices it services. This raises questions about data ownership and privacy.

Privacy and data collection

Many IoT devices collect lots of data as part of their operation. For example, a smart thermostat collects temperature data about its environment. This is required for it to function. This data may seem harmless at first glance, but once you consider how people use smart thermostats, you realize that the data is more important than it first appears.

In the smart thermostat example, people will set different temperatures based on when they expect to be awake, asleep, or away. From this data, you can infer approximately at what time someone leaves for work in the morning...
