Abstract

Supervisory Control and Data Acquisition, otherwise known as SCADA, is a system for gathering real time data, controlling processes, and monitoring equipment from remote locations. As more companies are implementing an open SCADA architecture through the Internet to monitor critical infrastructure components such as power plants, oil and gas pipelines, chemical refineries, flood control dams, and waste and water systems, vital systems are becoming increasingly open to attack. This paper provides an overview of SCADA, outlines several vulnerabilities of SCADA systems, presents data on known and possible threats, and provides particular remediation strategies for protecting these systems.
