Insecure encryption algorithm - Default encryption
Description
Some Amazon services support Key Management Service (KMS). As a good practice, it is recommended to use Customer Controlled Keys (CMK) instead of the default keys, in order to take full advantage of the KMS service.
Impact
- Obtain sensitive information in plain text
- Lose the malleability and control offered by a Customer Managed Key
Recommendation
Enable the encryption using KMS Customer Controlled Keys (CMK)
Threat
Authenticated attacker from the Internet with access to the service
Expected Remediation Time
⌚ minutes.
