CYBER-THREAT INTELLIGENCE SHARING USING BLOCKCHAIN TECHNOLOGY
Sharing cyber-threat intelligence is an operation that provides incident response teams and organisations with actionable data that they can use to protect themselves and their constituents. It requires the careful-handling and dissemination of sensitive security data. Whilst there are products from numerous vendors to achieve this, there is a barrier-to-entry for organisations and incident response teams to participate in these networks because of the issue of data provenance and trust.

Blockchain introduces the concept of 'trustless' networks, whereby non-trusting entities can participate in a distributed setting and deploy database transaction rules via Smart Contracts. Moreover, blockchain systems provide a layer of data provenance by-design. This project focusses on the secure dissemination of security-sensitive data utilising blockchain technology in a permissioned network setting.
