SD-WAN (Software-Defined Wide Area Network) is a technology that allows organizations to use multiple, low-cost Internet connections to create a secure and dynamic WAN. SD-WAN can provide benefits such as lower costs, higher performance, and easier management compared to traditional WAN technologies, such as MPLS (Multiprotocol Label Switching).
However, SD-WAN also introduces some potential risks, such as:
* The reliability and security of the Internet connections, which may vary depending on the location, provider, and traffic conditions.
* The compatibility and interoperability of the SD-WAN hardware and software, which may come from different vendors or use different standards.
* The availability and quality of the SD-WAN provider's support, which may depend on the provider's size, reputation, and outsourcing practices.
In this case, the CISO would most likely identify the risk that the SD-WAN provider uses a third party for support, because this could:
* Affect the organization's ability to resolve issues or request changes in a timely and effective manner.
* Expose the organization's network data and configuration to unauthorized or malicious parties.
* Increase the complexity and uncertainty of the SD-WAN service level agreement (SLA) and contract terms.
