Walk me through the steps involved in creating an encrypted EBS volume, ensuring the data at rest and in transit is secure.
To create an encrypted EBS volume and ensure data security at rest and in transit, follow these steps :
1. Create a Key Management Service (KMS) customer master key (CMK) for encryption if not already available. Use AWS Management Console, CLI, or SDKs.
2. Launch an EC2 instance with an IAM role that grants permissions to use the CMK for encryption/decryption operations.
3. Create an encrypted EBS volume using the KMS CMK by specifying the “kmsKeyId” parameter when creating the volume via AWS Management Console, CLI, or SDKs.
4. Attach the encrypted EBS volume to the EC2 instance launched earlier.
5. Enable in-transit encryption by configuring the instance’s security group rules to allow only encrypted traffic (e.g., HTTPS, SSH).
6. For additional security, enable Amazon EBS encryption on snapshots created from the encrypted volume, ensuring data remains encrypted during backup and restore processes.
