SCADA system security in power system protection

Includes bibliographical references (pages 23-23)Supervisory Control And Data Acquisition (SCADA) is a system, which controls and monitors the paired device data. This paper discusses the basic concepts of SCADA and their components. It also discusses the need for security in SCADA system and different vulnerable effects caused due to complexity of the system and different methods to reduce those effects. One of such effect on SCADA system is Distributed Denial Of Service (DDOS) attack, which may cause the black out of the whole system. This paper discusses the two methods OPL architecture and Test-Bed Development to reduce the DDOS attack on SCADA system
