With the rise of malware targeting industrial control systems, researchers need more tools to develop a better understanding of the networks under attack, the potential behavior of malware, and design possible defenses. One of the most important protocols used in practice today is IEC 104, which is used to monitor and control the Power Grid of several countries, as well as to monitor and control other critical infrastructures such as gas, oil, and water systems. In this paper we present our preliminary results in implementing the IEC 104 industrial protocol standard in Python and integrate it to a network emulation tool supported by Mininet.

Modern electrical substations are managed by intelligent electronic devices communicating through Ethernet-based networks. Because of the highly critical roles of substations, which include safety and protection, electronic devices need to be configured automatically through highly reliable and low-latency networks. This gives substation networks some requirements not addressed by previous industrial network standards. To address these unique challenges, IEC 61850 provides a collection of protocols and a model for the automatic configuration of digital substations. This article briefly overviews this standard and the security efforts to protect substations from attacks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
