Azure Key Vault Secret Rotation - Enterprise Security Automation

Azure Key Vault Azure Security Security Automation Azure Functions Secret Rotation DevSecOps

The Challenge

Service Principal secrets and Storage Account access keys were never rotated, creating massive security risks. Manual rotation was error-prone, caused downtime, and teams forgot expiration dates. No centralized monitoring existed for credential lifecycle.

My Solution

Implemented an automated secret rotation system using Azure Functions and Logic Apps. The system monitors expiration dates for Service Principal secrets and Storage Account keys, automatically generates new credentials before expiry, stores them securely in Azure Key Vault with versioning, and updates consuming applications—all without human intervention. Slack notifications alert teams of rotation events.

The Impact

Secrets Rotated
