Abstract

Effective detection and mitigation of DDoS attacks directly depend on the quality of the information sources used as input for the intrusion detection systems employed. Undoubtedly, one of the best sources of information is the network traffic captured on the network interfaces of the devices under protection, especially in IoT environments. In this way, network intrusion detection systems share network traffic information among themselves in a collaborative manner to act in the detection and mitigation of attacks on IoT networks. These attacks aim to intrude into the network to violate transmitted data or to deny services to IoT devices. However, communication between NIDSs can be compromised by one of these attacks before detection, thus, the need arises to make information sharing resilient between NIDSs to offer greater security for the operation of the collaborative NIDS. Blockchain is a promising approach to secure communication between NIDSs and make it resilient to denial-of-service attacks, secure, and trustworthy due to its properties of immutability, transparency, and decentralization.
