| Abstract | Substation security plays an important role in the delivery system of electrical energy. During the past years, there has been an increase in the number of attacks on automation systems. In spite of that, there has not been enough focus dedicated to the protection of such networks. In this paper, we introduce a novel machine learning based intrusion detection system targeted at automation networks of substations based on the IEC 60780-5-104 protocol. The novelty of our approach opposed to the state-of-the-art is the monitoring of several features on multiple protocol layers, which enables the identification of multiple types of attacks. Firstly, we simulate the communication between the substation slave and the server based on data gained from real substations and we simulate the systems behaviour under attack, too. Secondly, we observe the system's normal behavior and its behavior under the attack, in order to extract features needed for building an anomaly detection system. Lastly, based on these features we suggest an anomaly detection system for the asynchronous IEC 60870-5-104 protocol. We designed the anomaly detection model by using machine learning from the IEC 60870-5-104 protocol data acquired. The classifier with the highest performance was chosen by comparing 7 different classification algorithms: the Rule Learner classifier algorithm turned out to be the best. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
