Executive Summary

An overview of Supervisory Control And Data Acquisition (SCADA) systems is presented and relevant security concerns are addressed. To secure IP-based SCADA systems, it is vital to implement secure architectures which prevent access to the SCADA from corporate IT, in addition to excellent management practices in managing IP-based networks. The authors give an overall explanation of SCADA systems along with their security concerns and vulnerability. In the case of legacy SCADA systems, the concerns regarding security were minimal since it used proprietary networks; however, since the move of SCADA systems to the Internet, security problems have become an imperative issue, especially problems regarding IP-based systems.
