The DCS-CI series has its origins in the DCS-Water conferences, which focused specifically on the cybersecurity challenges facing water and wastewater utilities. DCS-Water 24 and DCS-Water 25, co-hosted by iTrust research centre at the Singapore University of Technology and Design and The Water Tower, brought together world-leading experts to address operational technology (OT) vulnerabilities, cyber-physical attack scenarios, and resilience strategies for water critical infrastructure.

DCS-CI 26 expands upon this foundation. While water infrastructure remains a vital concern, the conference now embraces the full spectrum of critical infrastructure sectors: energy, transportation, healthcare, telecommunications, and beyond. This broader scope reflects the recognition that many of the challenges—and many of the solutions—transcend sectoral boundaries. Secure-by-design principles, threat modeling frameworks, and resilience engineering methodologies are applicable across all domains where cyber and physical systems intersect.
