title = "A new network model for cyber threat intelligence sharing using blockchain technology",
abstract = "The aim of this research is to propose a new blockchain network model that facilitates the secure dissemination of Cyber Threat Intelligence (CTI) data. The primary motivations for this study are based around the recent changes to information security legislation in the European Union and the challenges that Computer Security and Incident Response Teams (CSIRT) face when trying to share actionable and highly sensitive data within systems where participants do not always share the same interests or motivations. We discuss the common problems within the domain of CTI sharing and we propose a new model, that leverages the security properties of blockchain. Our model provides a more effective and efficient framework for a CTI sharing network that has the potential to overcome the trust barriers and data privacy issues inherent in this domain. We implemented a testbed using Hyperledger Fabric and the STIX 2.0 protocol and validated the efficacy of the segmentation, implemented using smart contracts and Fabric channels.",
