An Architecture for Blockchain-Enabled Collaborative Signature-based Intrusion Detection System

Despite the promising benefits such as expanded signature databases and alert data from multiple sites, trust management and consensus building remain as challenges for a Collaborative Intrusion Detection System (CIDS) to work effectively. The blockchain technology with built-in immutability and consensus building capability provides a viable solution to the issues of CIDS. In this paper, we introduce an architecture for a blockchain-enabled signature-based collaborative IDS.
