*5.1. Building Testbeds for Water Systems*

Much of the existing research in this area involves a pool of resources (SWaT and WADI testbeds, epanetCPA toolbox, and datasets) provided by the iTrust Centre for research in cyber-security. Researchers associated with the iTrust Centre demonstrate the importance of developing and providing access to a real physical testbed for carrying out security research. Most of the existing studies have focused on drinking water systems, primarily those responsible for water distribution. Given the diversity of water and wastewater systems, more work in this area would provide obvious benefits, especially through testbeds involving water systems such as sewer and wastewater systems, and irrigation systems; these could be used to further validate the applicability of existing research. Although of immense value, building and maintaining realistic operational testbeds is not an easy task and requires significant and ongoing access to resources, skills and people.
