A municipality replaces branch routers with SD-WAN and API-driven SDN controllers. A mis-pushed policy briefly black-holed traffic and later opened an unintended path between guest and finance VLANs. Which security awareness should guide ongoing SD-WAN and SDN operations?
Select an answer to reveal the explanation.
Short Explanation
SD-WAN can rewire the whole city with one bad API call—like flipping every traffic light from one console. Guard who can push policy, watch the controller, and double-check that automation didn’t open a sneak path or drop a neighborhood offline.
Full Explanation
Software-defined and SD-WAN architectures concentrate risk in controllers, APIs, and automated policy. Secure operation requires hardened management access, least-privilege orchestration credentials, change control, and validation that intended segmentation and availability remain intact after pushes. Centralization improves consistency only when governance prevents both outage-inducing black holes and unintended exposure between security zones.
