What security protocols are leveraged by REST APIs in Cisco SD-WAN?

REST APIs in Cisco SD-WAN utilize both HTTP and HTTPS as their primary security protocols. HTTP is the foundational protocol for web communication, enabling the transfer of data between clients and servers. However, for secure communication, including the protection of sensitive data and authentication processes, HTTPS is utilized. HTTPS adds a layer of security by using SSL/TLS to encrypt the data transmitted over the network, ensuring confidentiality and integrity.

This dual usage of HTTP and HTTPS provides a secure framework for API interactions, allowing for the standard data operations of RESTful services while maintaining the necessary security measures for enterprise environments. While other options like SSH, FTP, and SFTP are common in different contexts of networking and data transfer, they are not applicable in the specific context of REST APIs in Cisco SD-WAN, which primarily focus on HTTP and HTTPS for their operations.
