The increasing number of Distributed Denial-of-Service (DDoS) attacks leads to a growing research and development interest in DDoS defense systems. As a response to the increasingly distributed nature of DDoS attacks, many organizations have demonstrated willingness to exchange information concerning threats, incidents, and mitigation strategies. Blockchain is, in this regard, a viable threat sharing platform, where different organizations can interact in a verifiable manner. This paper tackles the security visualization and management issue in a blockchain-based collaborative defense platform, defining an interactive dashboard displaying on-going threat mitigation status and enabling security analysts to react on threats on an individual or group level. The dashboard was implemented and evaluated on real hardware emulating the exchange of threats between three isolated Autonomous Systems (AS).
