A city's microservices platform firewalled only north-south Internet edges while east-west service-to-service chatter remains unmonitored and unrestricted. What design correction is needed?
Select an answer to reveal the explanation.
Short Explanation
Guarding the front door while cubicles pass secrets hand-to-hand is yesterday's castle model. East-west traffic inside needs eyes and limits too—not just the Internet edge.
Full Explanation
North-south traffic crosses the external boundary; east-west traffic moves laterally between internal services. Modern architectures require inspection, authentication, and segmentation for both directions because perimeter-only firewalls miss internal compromise paths. Designing for dual flow types is core to Domain 4 secure network architecture.
