Intelligent Intrusion Detection System Based on Blockchain Technology

Computer networks are increasingly vulnerable to security disruptions such as congestion, malicious access, and attacks. Intrusion Detection Systems (IDS) play a crucial role in identifying and mitigating these threats. However, many IDSs have limitations, including reduced performance in terms of scalability, configurability, and fault tolerance. In this context, we aim to enhance intrusion detection through a cooperative approach. To achieve this, we propose the implementation of ICIDS-BB (Intelligent Cooperative Intrusion Detection System based on Blockchain). This system leverages Blockchain technology to secure data exchange among collaborative components. Internally, we employ two machine learning algorithms, the decision tree and random forest, to improve attack detection.
