Credential rotation is the process of regularly updating credentials (like passwords, API keys, or certificates) to reduce the risk of unauthorized access if they are compromised. Here’s how to implement it effectively:
Steps to Implement Credential Rotation
-
Identify Credentials
- List all credentials in use (e.g., database passwords, service accounts, API keys, TLS certificates).
-
Automate Rotation
- Use tools or scripts to rotate credentials automatically at scheduled intervals.
- For example, rotate API keys every 90 days or database passwords monthly.
-
Update Dependencies
- Ensure all systems using the old credentials are updated to the new ones.
- Example: If rotating a database password, update the connection strings in applications.
-
Validate Access
- After rotation, verify that services can still access resources with the new credentials.
-
Monitor & Log
- Track rotation events and alert on failures (e.g., if an application fails to authenticate).
Example: Rotating API Keys
- Scenario: A web app uses a third-party API with an expiring key.
- Solution:
- Generate a new API key via the provider’s portal.
- Update the key in the app’s configuration.
- Deprecate the old key after confirming the new one works.
Example: Rotating Database Credentials
- Scenario: A MySQL database password needs rotation.
- Solution:
- Generate a new password in the database.
- Update the password in the app’s config files or secrets manager.
- Restart services if needed.
Best Practices
- Use Secrets Management: Store credentials securely (e.g., Tencent Cloud Secrets Manager).
- Enforce Least Privilege: Rotate credentials with minimal required permissions.
- Schedule Regularly: Automate rotations (e.g., monthly for passwords, quarterly for certificates).
For Tencent Cloud, use Secrets Manager to securely store and rotate credentials automatically. It integrates with databases, Kubernetes, and applications to manage secrets efficiently.
