Attacking and Securing Industrial Control Systems (ICS)

Industrial Control Systems (ICS) are often a sitting target for cybercriminals. The majority of these systems monitor complex industrial processes and critical infrastructures that deliver power, water, transport, manufacturing and other essential services.

There are many vulnerabilities in ICS systems that could expose an installation to attacks. Downtime or infiltration of an ICS network could result in massive outages, hundreds of thousands of impacted users and even national disaster. Penetration testing on ICS systems is a very specific field that requires in-depth knowledge and hardware availability.

This training is going to help you to understand ICS systems, analyse their weaknesses, attack them and design strategies to protect them. It is aimed at security professionals who want to understand ICS systems, improve their skills or specialize in ICS security, and will take them from the fundamentals of ICS security to advanced hacking techniques.

The focus will be on methodologies for hacking commercial hardware devices such as PLCs as well as simulators, and will also provide an excellent opportunity for participants to gain hands-on experience in penetration testing of these devices and systems. The ICS setup will simulate the ICS infrastructure with real-time PLCs and SCADA applications. The training will cover the most common ICS protocols (Modbus, S7, DNP3, OPC, Profinet), analysing packet captures and learning how to use these protocols to talk to PLCs. The training will also incorporate how to program a PLC, to improve understanding of how they can be exploited. There will be modules on how to bypass airgaps, how to defend airgapped systems, and also the techniques and tactics that adversaries use to compromise ICS systems.

Throughout the course a virtual machine created by Dreamlab specifically for ICS penetration tests will be used, it includes all the necessary tools for ICS hacking. The course is structured for beginner to intermediate level assistants and there is no requirement for previous experience in ICS, reversing or hardware.
