While demands on wide area network (WAN) services are gradually increasing, the regular WAN is struggling to cope with the high network services requirements.Recent software-defined wide area networks (SD-WAN) technology has provided a robust network system to handle large and increasing network loads.SD-WAN is providing a central and programmable control on the network system, which ensures more flexibility and agility.Moreover, as it enables the cloud use for network services, security becomes a significant challenge in SD-WAN.As a result, several types of threats among the three network planes need to be handled through a stable security system integrated with the SD-WAN.This article reviews the significant challenges faced in SD-WAN systems facing each plane of the SD-WAN structure, such as intersection attacks, leakage of information threats, and eavesdropping attacks.
