Development of industrial network forensics lessons

Most forensic investigators are trained to recognize abusive network behavior in conventional information systems, but they may not know how to detect anomalous traffic patterns in industrial control systems (ICS) that manage critical infrastructure services. We have developed and laboratory-tested hands-on teaching material to introduce students to forensics investigation of intrusions on an industrial network. Rather than using prototypes of ICS components, our approach utilizes commercial industrial products to provide students a more realistic simulation of an ICS network. The lessons cover four different types of attacks and the corresponding post-incident network data analysis.
