This is not your traditional SCADA, ICS, IIoT security course! How many courses send you home with lifetime access to course updates and a $500 kit including your own PLC and a set of hardware RF hacking tools?!? This course teaches hands-on penetration testing techniques used to test individual components of a control system, including embedded electronic field devices, network protocols, RF communications, Human Machine Interfaces (HMIs), and various forms of master servers and their ICS applications. Skills you will learn in this course will apply directly to systems such as the Smart Grid, PLCs, RTUs, smart meters, building management, manufacturing, Home Area Networks (HAN), smart appliances, SCADA, substation automation, synchrophasors, and even IoT.
This course is structured around the formal penetration testing methodology created by UtiliSec for the United States Department of Energy. Using this methodology and the ControlThings Platform (previously SamuraiSTFU), an open source Linux distribution for pentesting energy sector systems and other critical infrastructure, we will perform hands-on penetration testing tasks on user interfaces (on master servers and field device maintenance interfaces), control system protocols (modbus, DNP3, IEC 60870-5-104), proprietary RF communications (433MHz, 869MHz, 915MHz), and embedded circuit attacks (memory dumping, bus snooping, JTAG, and firmware analysis). We will tie these techniques and exercises back to control system devices that can be tested using these techniques. The course exercises will be performed on a mixture of real world and simulated devices to give attendees the most realistic experience possible in a portable classroom setting.
Advances in modern control systems, including initiatives such as the Smart Grid and Industry 4.0, have brought great benefits for asset owners/operators and customers alike, however these benefits have often come at a cost from a security perspective. With increased functionality and additional inter-system communication, modern control systems bring a greater risk of compromise that vendors, asset owners/operators, and society in general must accept to realize the desired benefits. To minimize this risk, penetration testing in conjunction with other security assessment types must be performed to minimize vulnerabilities before attackers can exploit critical infrastructures that exist in all countries around the world. Ultimately, this is the goal of this course, to help you know how, when, and where this can be done safely in your control systems.

This course is designed for intermediate level security professionals, be they engineers, technicians, analysts, managers, or penetration testers. Basic penetration testing experience is desirable, but not required. It is assumed that attendees will have no knowledge of ICS, Smart Grid, SCADA, or critical infrastructure.
Recommended Reading before the Course:
For those with little or no ICS experience, these Wikipedia articles provide a brief introduction to the concepts and history of control systems that will be helpful to know for class.
NIST 800-82 is a great introduction to industrial control systems, the security issues surrounding them, and basic cyber defenses
Since this course will be getting very deep into the technical weeds of communications, it would be helpful to have a basic understanding of the following encoding methods: ASCII, Unicode, UTF-8, UTF-16, and UTF-32
