Hyperledger Fabric vulnerability assessment
The scope of this thesis is the vulnerability assessment of the new version of Hyperledger Fabric (2.x), a popular platform for the development of DLT applications (Distributed Ledger Technology), which was release in January 2020. More specifically, Hyperledger Fabric is an open source software that provides the infrastructure for building private permissioned blockchain networks and is designed for use in enterprise contexts. In the context of our research, we will inspect each entity of a Hyperledger Fabric network separatelt, in order to identify possible vulnerabilities, with our primary consideration being the three basic security principles, Confidentiality, Integrity and Availability. At the same time, we will compare our findings with those documented in related works that have been conducted regarding previous Hyperledger Fabric versions, in order to determine whether known vulnerabilities have been mitigated in the new version. Consequently, this thesis constitutes an attempt to inspect the components of Hyperledger Fabric from a security point of view in an exhaustive manner, combining, extending and verifying the existing publications and experiments in the process, with the goal of evaluating the overall security level in the latest release.
