Hyperledger Global Forum 2021

Hyperledger Fabric is increasingly being deployed in production environments by many users, as evident from the many successful Hyperledger use cases. Thus it becomes paramount to detect attempts at attacking them. Our research focuses on monitoring Hyperledger Fabric for ongoing attacks and threats. We chose the Hyperledger Explorer project instead of a SIEM solution, since it offers a good starting point for data analytics with Hyperledger Fabric. For this purpose we extend Explorer with additional data collection and security monitoring features, while contributing bug fixes upstream. The bulk of our development work focused on developing appropriate visualizations for security experts to aid them in detecting attacks. Our talk will focus on the development of these visualizations and the technical challenges we faced with data sources and integration of these Hyperledger projects.
