The Cyber Security Agency of Singapore (CSA) has developed the Operational Technology (OT) Cybersecurity Masterplan as part of our continuous efforts to enhance the security and resilience of Singapore’s Critical Information Infrastructure (CII) sectors in delivering essential services. The Masterplan serves to improve cross-sector response to mitigate cyber threats in the OT environment and to strengthen partnerships with industry and stakeholders. The OT Cybersecurity Masterplan outlines key initiatives covering the areas of People, Processes and Technology to uplift the cybersecurity postures of our CII owners and organisations that operate OT systems.
