In this talk we describe the Secure Water Treatment (SWaT) testbed at the iTrust Centre for Research in Cybersecurity (Singapore University of Technology and Design). SWaT is a testbed built to design, implement and test advanced ICS security mechanisms on a realistic setting, operating since 2015. We will share ongoing research efforts to detect and mitigate attacks to SWaT. We will also introduce two new testbeds on water distribution (WADI) and electric power grid (EPIC).
Background
SWaT Architecture - SWaT consists of a modern six-stage process. The process begins by taking in raw water, adding necessary chemicals to it, filtering it via an Ultrafiltration (UF) system, de-chlorinating it using UV lamps, and then feeding it to a Reverse Osmosis (RO) system. A backwash process cleans the membranes in UF using the water produced by RO. The cyber portion of SWaT consists of a layered communications network, Programmable Logic Controllers (PLCs), Human Machine Interfaces (HMIs), Supervisory Control and Data Acquisition (SCADA) workstation, and a Historian. Data from sensors is available to the SCADA system and recorded by the Historian for subsequent analysis.
