Pentesting Industrial Control Systems

By: Paul Smith

Overview of this book

The industrial cybersecurity domain has grown significantly in recent years. To completely secure critical infrastructure, red teams must be employed to continuously test and exploit the security integrity of a company's people, processes, and products. This is a unique pentesting book, which takes a different approach by helping you gain hands-on experience with equipment that you’ll come across in the field. This will enable you to understand how industrial equipment interacts and operates within an operational environment. You'll start by getting to grips with the basics of industrial processes, and then see how to create and break the process, along with gathering open-source intel to create a threat landscape for your potential customer. As you advance, you'll find out how to install and utilize offensive techniques used by professional hackers. Throughout the book, you'll explore industrial equipment, port and service discovery, pivoting, and much more, before finally launching attacks against systems in an industrial network. By the end of this penetration testing book, you'll not only understand how to analyze and navigate the intricacies of an industrial control system (ICS), but you'll also have developed essential offensive and defensive skills to proactively protect industrial networks from modern cyberattacks.

Chapter 11: Whoot… I Have To Go Deep

After reading the previous chapter, we have a foothold/shell, but now what? Next, we need to understand where we have landed and what we have access to. This includes gathering as much information as possible, harvesting credentials, mapping network connections, using proxies to run internal network scans, and discovering pivotable hosts. This is the phase where we need to traverse the inside of the system. We can accomplish this by using tools to map the network through proxies and go deeper. Depending on the entry point, there will be key information to discover, including clues, which will provide details about lower-level systems that will be required to get down to the physical I/O.

In this chapter, we will be installing a firewall that will allow us to build out segmentation in our lab network. After gaining initial access to a network, this tends to be where people get stuck and typically ask questions such as, what do I do now...
