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.

Summary

In this chapter, we looked at how packets are formed by reviewing the OSI model and understanding the various layers that exist in the model. We took this one step further by analyzing the structure of an IPv4 packet and performing a side-by-side comparison of this with a packet that we captured from our lab equipment. After providing a better understanding of what packets are and how they are constructed, we went on to use Wireshark to capture these packets. We made use of the mirror port that we created in the previous chapter, and we discussed the differences between capture filters and display filters.

Finally, we downloaded some PCAPs from an open source ICS lab and we used Wireshark to analyze the traffic that we found in these packet captures. We leveraged display filters to narrow down key network data, such as valid credentials, operational web portals, and working network cameras. Understanding and practicing these techniques and methods will allow you to have...
