Development of SCADA Simulator using Omnet++

Industrial control systems (ICS) are used to automate many industries like power generation, petroleum, manufacturing, traffic control etc. Increase in the use of IT (information technology) components in ICS introduces many new vulnerabilities. Security breach in ICS can cause serious damages and is threat to human life. Simulating Security threats and security controls for ICS can help to identify threats and mitigation in advance. This paper explain the construction of open source SCADA simulator which can be used for security testing. Building SCADA simulation using Omnet++ is discussed in detail. We also analyzed TCP Flood DDOS attack on power distribution system as case study.
