Networks that use RPL are vulnerable to security concerns called RPL flood attacks. The IPv6 Routing Protocol for Low-Power and Lossy Networks mitigation technique Secure-RPL is proposed in this study to effectively identify and prevent DIS flooding attacks with minimal overhead. Malicious nodes overload available resources, obstruct communication, and impede data transfer, which may result in performance issues and service outages. It is essential to use countermeasures like message filtering and intrusion detection systems. This chapter shows that the DIS flooding assault increases the network's control packet overhead, greatly degrading network performance. This raises the network nodes' power consumption. To solve this issue, a mitigation strategy called Secure-RPL is proposed. The suggested approach considerably reduces the impact of a DIS flooding attack on the network performance. The effectiveness of the suggested Secure-RPL system is compared to the normal RPL protocol.
