Securing the City: Essential Practices for SCADA System Management

Abstract

Supervisory Control and Data Acquisition (SCADA) systems are critical for managing essential city services like water treatment, waste management, and electricity generation. However, implementing and maintaining these systems presents significant challenges for IT leaders. This study, conducted in collaboration with the City of Spokane's Public Works IT Team, examines the application and maintenance of SCADA systems within the city. Through interviews with the IT Team, the study identifies seven key lessons for IT leaders seeking to enhance SCADA system efficiency. These lessons address common issues, including the importance of understanding system requirements and costs, regulating updates, establishing a non-production practice environment, implementing a change management process, prioritizing safety, fostering open communication channels, and investing in staff training. The study also outlines four prevalent SCADA-related problems with recommended solutions, aimed at optimizing organizational performance and system reliability. This research offers valuable insights for IT leaders working with SCADA systems in mid-sized cities and beyond, contributing to the growing body of knowledge on effective SCADA management practices.
