Optimizing Packet Filtering Libraries for Scada System Security

Supervisory Control and Data Acquisition (Scada) systems have been traditionally used since a long time to control the critical infrastructure of many countries. The amount of complexity in Scada networks coupled with lack of security has caused an urgency to upgrade existing systems to withstand hostile attacks. In our work, we dissect these large Scada networks at the protocol level on which they operate, and further dive into the packet...
