For organizations to communicate important data across various branches, a reliable Wide Area Network (WAN) is important. With the increase of several factors such as usage of cloud services, WAN bandwidth demand, cost of leased lines, complexity in building/managing WAN and changing business needs led to need of next generation WAN. Software-defined wide area network (SD- WAN) is an emerging trend in today’s networking world as it simplifies management of network and provides seamless integration with the cloud. Compared to Multiprotocol Label Switching (MPLS) majorly used in traditional WAN architecture, SD-WAN incurs less cost, highly secure and offers great performance. This paper will mainly focus to investigate this next-generation WAN’s security attributes as security plays a crucial role in SD-WAN implementation. The goal of the paper is to analyze SD-WAN security by applying principles of CIA triad principle. Comparison of SD-WAN products offered by three different vendors in SD-WAN market with respect to its security is another important area that will be covered in this paper.
