Intelligent Security System for HMI in SCADA Applications

Abstract

 Abstract—Supervisory control and data acquisition (SCADA) systems are vital components of most nations' critical infrastructures. They control pipelines, water and transportation systems, utilities, refineries, chemical plants, and a wide variety of manufacturing operations. SCADA provides managing the real-time data on production operations, implements more efficient control paradigms, improves plant and personnel safety, and reduces costs of operation. These benefits are made possible by the use of standard hardware and software in SCADA systems combined with improved communication protocols and increased connectivity to outside networks, including the Internet. However, these benefits are acquired at the price of increased vulnerability to attacks or erroneous actions from a variety of external and internal sources. This paper focuses on suggesting a user security on the basis of roles assigned to multi users with the help of password and biometrics with iris recognition security. Recommending a role based hierarchy to allow users access system according to their capabilities in the particular application.
