CIDS: Collaborative Intrusion Detection System using Blockchain technology

Due to the colossal advancement of cyber security threats and attacks, intrusion detection system (IDS) seems to shift their culture toward more collaborative working methods. An aggressor can exploit these vulnerabilities and penetrate the network organisation. There is a tremendous demand for larger networking set-ups to be secured in order to protect from malicious activities. Collaborative Intrusion Detection Networks (CIDN) techniques have been deployed in pragmatic scenarios to maximise the realistic detection performance, allowing a collection of IDS nodes to share and communicate mandatory information, such as signature-based IDS and attack alerts. Due to the distributed system of CIDN, there is an immense likelihood of insider security threats presenting the susceptibility of the system. In this paper, we examine the potential of Blockchain technology to enhance the robustness and efficiency of CIDSs in terms of trust management by proposing a CIDSs architecture based on Hyperledger Fabric and Snort IDS.
