Wrapping Key Rotation is a crucial security practice in Databunker Pro that helps maintain the confidentiality and integrity of the encrypted data over time.
What is the Wrapping Key?
The Wrapping Key is a cryptographic key used to encrypt the Master Key in Databunker Pro. It acts as an additional layer of protection for the Master Key
Importance of Key Rotation:
- Limiting Key Exposure: Regular rotation reduces the window of opportunity for potential attackers to compromise the key.
- Compliance: Many security standards and regulations require periodic key rotation.
- Mitigating Long-term Attacks: Rotation helps protect against slow, persistent attempts to break encryption.
Best Practices:
- Rotate the Wrapping Key at regular intervals (e.g., every 90 days or annually).
- Implement automated reminders for key rotation.
- Maintain a secure log of key rotations for audit purposes.
- Test the rotation process regularly to ensure smooth execution when needed.
Recovery:
In case the current Wrapping Key is lost or compromised, Databunker Pro allows for recovery using Shamir Key Shares. This ensures that the Master Key can be safely re-encrypted with a new Wrapping Key without exposure.
