Penetration testing IoT networks and reverse engineering firmware

In this section, we will take a look at what IoT is and the various security aspects associated with it. As with any new technological advancement, IoT is also susceptible to security threats. In the past few years, we have seen interest and development from the security community toward standardizing the IoT segment; however, improvements still need to be made.

In this section, we will take a look at the security issues that affect IoT, such as hardcoded passwords, lack of security by design, and so on, as well as the proposed solutions that can help make it more secure. We will also look at UARTs and understand how they function, along with different attributes of firmware and reasons for reverse engineering them.

Introduction to IoT network security

IoT is an evolving concept that consists of home appliances, vehicles, and other electronically embedded sensors and software that enables connectivity among these applications...
