Description

Software-Defined Networks (SDNs) have emerged particularly for medium and large scale networks since they introduce agility and flexibility with the help of centralized network management by abstracting control plane from data forwarding plane. Although this centralized architecture provides various advantages in terms of effortlessly managing and optimizing network resources, this makes SDN vulnerable to conventional distributed denial of service (DDoS) attacks by making the network inoperable due to the overloaded network traffic. To address the vulnerability, in this work, we propose a detection and countermeasure scheme based on continuous wavelet transform (CWT) and convolutional neural network (CNN). The scheme uses features obtained from CWT as the input for the CNN classifier to differentiate attack samples from the normal ones. Our experimental results show that the proposed scheme achieves high detection rate against DNS amplification, NTP and TCP-SYN flood attacks with a remarkably low false alarm rate.
