Security Issues in SD-WAN by understanding the common risks and vulnerabilities that can impact software-defined wide area networks in enterprise environments. This training covers security challenges such as data interception, misconfigured policies, weak authentication, and insecure traffic routing across distributed networks. It explains how SD-WAN environments can be exposed to threats if encryption, access control, and monitoring are not properly implemented. You will learn how security gaps affect branch connectivity, cloud integration, and application performance. The course also covers risks related to VPN misuse, device compromise, unauthorized access, and lack of visibility into network traffic. It focuses on identifying vulnerabilities and improving security practices to strengthen SD-WAN protection and resilience.
