SD-WAN Threat Landscape

The goal of this paper is to understand SD-WAN threats using practical approach. We describe basic SD-WAN features and components, investigate an attack surface, explore various vendor features and their security, explain threats and vulnerabilities found in SD-WAN products. We also extend existing SDN threat models by describing new potential threats and attack vectors, provide examples, and consider high-level approaches for their mitigations.
