In this course, we will explore several technologies that bring modern devices together, facilitating a network of connected things and making devices internet enabled. We will discuss rules, protocols, and standards for these devices to communicate with each other in the network. We will also go through security and privacy issues and challenges in cyber physical systems (CPS). We will explore measures and techniques for securing systems from different perspectives. Possible attack models are introduced and solutions to tackle such attacks are discussed. Moreover, some basic concepts related to privacy in cyber physical systems are presented.

In the first three courses of this specialization, you were focused on understanding how computer networks work and how to access the network. Now that you have a firm grasp of that, you can dive deeper into how do you actually build and secure a home network that includes lots of wireless devices. Wireless requires different configurations than a wired network. Both wireless and wired networks are susceptible to security threats and attacks. You will work through the different types of threats and attacks that typically occur and understand the different software tools that can be used to mitigate those security threats.

In this course, we give an in-depth study of the TCP/IP protocols. We examine the details of how IP enables communications across a collection of networks. We pay particular attention to the hierarchical structure of IP addresses and explain their role in ensuring scalability of the Internet. The role of address prefixes and the uses of masks are explained in details.

In this course, we deal with the general issues regarding packet switching networks. We discuss packet networks from two perspectives. One perspective involves external view of the network, and is concerned with services that the network provides to the transport layer that operates above it at the end systems.

Learn how to model social and economic networks and their impact on human behavior. How do networks form, why do they exhibit certain patterns, and how does their structure impact diffusion, learning, and other behaviors? We will bring together models and techniques from economics, sociology, math, physics, statistics and computer science to answer these questions.

It is hard to imagine life without your Smartphone – you have come to rely on it so much – for your work; to stay in touch with family and friends; to capture and share those special moments; to find your way around in a new neighborhood. Did you ever wonder how and when all this happened? Or how and when GPS sensors came to be in your cell phone?

What makes WiFi faster at home than at a coffee shop? How does Google order its search results from the trillions of webpages on the Internet? Why does Verizon charge $15 for every GB of data we use? Is it really true that we are connected in six social steps or less? These are just a few of the many intriguing questions we can ask about the social and technical networks that form integral parts of our daily lives. This course is about exploring the answers, using a language that anyone can understand.
