How do you audit access to Key Vault?

Short answer: Enable diagnostic logging in Azure Key Vault. Logs include secret reads, updates, deletions, and authentication attempts. Can be sent to Log Analytics, Event Hub, or Storage Account.

Real-world example (ShopNest)

Connection strings and payment keys live in Key Vault—not in source control or plain appsettings on disk.
