Blockchain: Secured Solution for Signature Transfer in Distributed Intrusion Detection System

Exchange of data in networks necessitates provision security and confidentiality. Most compromised by intruders are those where the exchange is at high risk. The main objective this paper to present a solution for secure attack signatures between nodes distributed network. Malicious activities monitored detected Intrusion Detection System (IDS) that operates with connected IDS two phases, first phase consists detection anomaly attacks using an ensemble classifiers such as Random forest, Convolutional neural network, XGBoost along genetic algorithm improve performance IDS. novel converted into exchanged further through network blockchain framework second phase. This uses cryptosystem part store it higher level. implemented Hyperledger Fabric v1.0 v2.0, create prototype signature transfer. It exchanges much more secured manner architecture when version 2.0 Fabric. proposed system evaluated on UNSW NB15 dataset. Blockchain has been terms execution time, average latency, throughput transaction processing time. Experimental evidence demonstrates improved accuracy, rate false alarm (FAR) key parameters used. Accuracy increase 2% 3% respectively whereas FAR reduces 1.7%.
