Client-side Encryption is the best solution to encrypt customer credit card numbers before they are stored in the cloud and provide easy key management. Here's why:
Encryption Before Storage: Data is encrypted on the client-side (e.g., user's browser or device) before being sent to the cloud, ensuring that even if the cloud storage is compromised, the sensitive data remains protected.
Key Management: The encryption keys are managed by the client or a trusted key management system, providing greater control and flexibility.
Reduced Risk: Client-side encryption minimizes the risk of sensitive data being exposed in the cloud environment.
Why not the other options?
A. Edge Encryption: This is a broader term that can refer to various encryption techniques applied at the edge of the network.
B. Server-side Encryption: Data is encrypted on the server-side, which means the cloud provider has access to the encryption keys.
D. Database Encryption: This encrypts the entire database, but it doesn't provide the same level of control and key management as client-side encryption.
