This is not your traditional SCADA security course! How many courses send you home with 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, and master servers. Skill learned 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, and synchrophasors.  This course is structured around the formal penetration testing methodology created by UtiliSec for the United States Department of Energy.  Using this methodology and SamuraiSTFU (Security Testing Framework for Utilities), an open source Linux distribution for pentesting energy sector systems and other critical infrastructure, we'll 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), RF communications (433MHz, 869MHz, 915MHz), and embedded circuit attacks (memory dumping, bus snooping, JTAG, and firmware analysis).  We’ll 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 students the most realistic experience as possible in a portable classroom setting.

==Course Description==
  
Advances in modern control systems such as the energy sector’s “Smart Grid” brings great benefits for asset owners/operators and customers alike, however these benefits come at a cost from a security perspective. With increased functionality and addition inter-­‐system communication, modern control systems bring a greater risk of compromise that both asset owners/operators and customers 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.

Assessing and Exploiting Control Systems

This is not your traditional SCADA/ICS/IoT security course! How many courses send you home with your own PLC and a set of hardware/RF hacking tools?!? In this 3-day version of the course, you will receive all six days worth of slides.

Course Description

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, and synchrophasors. This course is structured around the formal penetration testing methodology created by UtiliSec for the United States Department of Energy. Using this methodology and Control Things Pentest 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), 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 students the most realistic experience as possible in a portable classroom setting.

Advances in modern control systems such as the energy sector’s Smart Grid has 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 addition 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.
