SCADA Security: A New Concerning Issue of an In-house EGAT-SCADA

As being an in-house technology, the development of EGAT-SCADA was firstly focused on what it can do. It is developed for supervising the operation on electric power transmission system through out the country of Thailand. It will be installed on five regional control centers, several dozens of group control centers, and more than two hundred substations. Moreover, an implementation on a hydro control center is in a plan. Since the first phase of development was completed, the security issue has become a major concern before the implementation. General procedures on IT security are essentially enforced. Special issues on SCADA security such as address resolution protocol (ARP) spoofing and SQL attacking were studied. Several tests were conducted. Currently, SCADA security is continuing studied for protecting EGAT-SCADA from unauthorized access and abuse. This paper will describe in detail the security concern of EGAT-SCADA
