Due to the increase in network traffic, the load on NIDS has escalated, leading to potential packet loss, which in turn increases the likelihood of failing to detect significant attacks. To address this issue, our study proposes a method using SDN (Software Defined Networking) to dynamically distribute traffic among multiple NIDS based on their load, thereby dispersing the burden. Furthermore, we evaluate the effectiveness of this method in one of the NIDS, Zeek.}, title = {SDNを用いた分散型NIDSに関する考察}, year = {2024} }
