If you've forgotten to encrypt the Root EBS volume attached to your servers, there's no need to worry! 🙅
Follow these 6 simple steps to resolve it: (Nobody would ever know 🙊 )
Stop the EC2 Instance🙋:
Identify the EC2 instance with the unencrypted volume and stop it to ensure data integrity.
Create an AMI/Snapshot of the existing unencrypted volume🔓.
Create an Encrypted Snapshot:🔐
Make a copy of the unencrypted snapshot and encrypt it during the copy process by using an available encryption key.
Provision a New Encrypted EBS Volume💾:
Create a new EBS volume from the encrypted snapshot.
Replace the Volume:
Detach the original unencrypted EBS volume and attach the new encrypted EBS volume, ensuring the device name matches (e.g., /dev/sda1).
Start the EC2 Instance:💻
Restart the instance and wait for it to pass all health checks to verify that the encrypted volume is functioning properly.
