Abstract: Abstract Supervisory, Control, and Data Acquisition (SCADA) systems are crucial to many critical infrastructures, typically those that operate in real-time environments. In the past, these systems were based on proprietary protocols and were isolated from other networks. However, as the trend towards standard IT practices has grown, there have been serious concerns regarding the security, reliability and availability of these systems, since they are increasingly connected to an enterprise network. There are many positive business benefits to be gained from this trend; however, this connectivity has increased the risks of exploitation of security vulnerabilities in these non-proprietary systems. These vulnerabilities, if exploited, can result in serious consequences such as degraded performance, loss and/or compromise of critical information, or in the worst case scenario, making these critical systems completely unavailable.
