Can you describe the process of encrypting data in Amazon RDS and the difference between encryption at rest and in-transit encryption?
Amazon RDS encryption involves two types: encryption at rest and in-transit encryption. Encryption at rest secures data stored on disk, using AWS Key Management Service (KMS) to manage keys. To enable it, select the “Enable encryption” option during instance creation. Existing instances require creating a snapshot, copying it with encryption enabled, and launching a new encrypted instance.
In-transit encryption protects data while transferring between client and RDS instance or between instances. It uses SSL/TLS certificates for secure connections. For enforcing SSL connections, modify the parameter group associated with the RDS instance, setting ‘rds.force_ssl’ to 1, and reboot the instance. Obtain the certificate from AWS Certificate Manager or use Amazon RDS’s default certificate.
The main difference is that encryption at rest safeguards stored data, while in-transit encryption secures data during transmission.
