The 311 application is redesigned as microservices. Which security implication is most important for the new architecture?
Select an answer to reveal the explanation.
Short Explanation
Chopping the app into many services creates more hallways between rooms—each hallway needs a badge check. East-west calls need authz, not blind trust. Treating internal traffic as automatically safe is how small cracks become big incidents.
Full Explanation
Microservices increase inter-service communication and therefore expand internal trust boundaries that must be secured with authentication, authorization, and network policy. Security architecture must address east-west traffic, not only the Internet-facing edge. Assuming automatic permanent isolation, anonymous internal calls, or one shared database credential undermines least privilege and zero-trust style service design.
