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.

Capturing packets on the wire

In the last section, we discussed what the OSI model is and the layers that formulate and structure the model. We reviewed how a packet is constructed and then directly compared the packet structure to the communication exchange we see between the PLC and engineering software. In this section, we are going to dive deeper into Wireshark and focus on some key features that I personally use during my engagements to capture traffic. As a recap, in Chapter 5, Span Me If You Can, we used Wireshark to verify that our mirror port was set up and configured correctly.

Now, I want to preface this upcoming content with two very distinct points, and give shout-outs to fellow security experts in the industry, as well as to content that I have personally leveraged in the past to hone my skills:

Both these resources provide different types of content. I have Wireshark 101 by...
