Anomalies detection in computer networks with the use of SDN

: In the paper, the authors present a method of anomalies detection and identification in network traffic using statistical signatures. There is also shown a new system architecture based on the Software-Defined Networking (SDN) which allows for application of statistical anomaly detection in computer networks. With the proposed hardware-software model, it becomes possible to implement custom algorithms for the threats detection with the use of recognized and secure communications standards. The proposed architecture has been built based on an open-source solutions and can be used directly in production environments.
