  The security of industrial network has become an increasing concern in
industry infrastructure operation. Motivated by on-going collaborations with
Fortinet Corp., a security company, this project implements a testbed for
supervisory control and data acquisition (SCADA) network security research by
software emulation. Concepts about SCADA and Modbus protocol are reviewed in
the report. Besides Modbus, vulnerabilities about several other industrial
protocols are also studied for this project. In this report, a typical tank
system following Modbus protocol is built as a testbed. Both attack and defense
toolkits are introduced to emulate the attack and protection of the Modbus
network. The emulation platform is also capable of entrapping hackers and
gathering their activity data.
