Towards Steganography Detection Through Network Traffic Visualisation
This addresses network security for detecting hidden data transmissions, but it is an initial step and likely incremental in the field of steganalysis.
The paper tackled the problem of detecting network steganography by proposing a new method based on traffic visualization without linear time dependencies, demonstrating its feasibility in a steg-tomography environment with a dedicated tool.
The paper presents initial step toward new network anomaly detection method that is based on traffic visualisation. The key design principle of the proposed approach is the lack of direct, linear time dependencies for the created network traffic visualisations. The method's feasibility is demonstrated in network steganography environment by presenting steg-tomography methodology and developing the dedicated visualisation tool. To authors' best knowledge this is the first utilization of network traffic visualisations for steganalysis purposes.
