Assessing and Exploiting Control Systems & IoT

Justin Searle, UtiliSec | July 22-25



Overview

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?!? 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.

Who Should Take this Course

Basic penetration testing experience is desirable, but not required. It is assumed that attendees will have no knowledge of control systems, Smart Grid, SCADA, or critical infrastructure. This course is designed for intermediate level security professionals, be they engineers, technicians, analysts, managers, or penetration testers.

Student Requirements

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:


What Students Should Bring

A laptop that meets the following requirements:
  • 64-bit processor with a 64-bit operating system
  • VT or other 64-bit virtualization settings enabled in your BIOS to run 64-bit VMs
  • At least eight (8) GB of RAM
  • At least forty (40) GB of free hard drive space
  • Windows 7 (with .NET 4.0), 8.x, or 10.x installed on your host laptop or inside a VM
  • At least two USB ports (three ports preferred). If only two USB ports exist on the laptop and they are right next to each other (such as found on a Macbook Air), a USB extension cable must be brought as well
  • VMware Player 12, VMware Workstation 12, or VWware Fusion 8 installed BEFORE class. Other virtualization software such as Parallels or VirtualBox may work if the attendee is familiar with its functionality, however VMware should be pre-installed as a backup just in case
  • Access to an account with administrative permissions and the ability to disable all security software on their laptop such as Antivirus and/or firewalls if needed for the class


What Students Will Be Provided With

The following items are provided to each student to use in class and to keep after course completion:
  • Programmable Logic Controller (PLC)
  • Software to program the PLC to keep (non-expiring)
  • Software to program an HMI for the PLC (non-expiring)
  • Buspirate with probes and EEPROMS for exercises
  • RTL-SDR (Software Defined Radio)
  • Great Scott Gadgets Yardstick sub-GHz Radio
  • Saleae Logic4 Analyzer
  • Breadboard with SPI and I2C EEPROMs
  • MSP430 Launchpad for Firmware exercises
  • Latest version of the Control Things Pentest Platform on USB
  • Power for your laptop
  • Internet connectivity may or may not be available depending on the facility hosting the course
