IT Security for SCADA: A Position Paper

SCADA Supervisory Control and Data Acquisition System is a cyber-physical system, wherein IT Information Technology components work in conjunction with field devices to control a physical process. The security of these IT components becomes crucial in view of the damaging effects that any security breach of these IT components can have on the underlying physical process. In response to this critical issue, various governments across the world have recognized the issue of SCADA security and have initiated the creation of a regulatory framework for mandating SCADA security in their respective countries. This paper provides a brief overview of the cyber-security issues of SCADA and the implications of Stuxnet for SCADA security. The paper reviews the steps taken by the governments of India and South Africa; and it provides guidance to the owners of SCADA regarding SCADA security, as mandated by the Government of India.
