Rule: Attached EBS Volumes Should Have Encryption Enabled

Rule Description:

Troubleshooting Steps:

2. 1.
   Validate EBS Volume Encryption:

   • Check if the attached EBS volumes have encryption enabled.
   • Verify if encryption is using AWS Key Management Service (KMS) or AWS managed keys.

Remediation Steps:

2. 1.

   Enable Encryption for EBS Volumes:

   • Identify the EBS volumes that are currently unencrypted.
   • Select the desired AWS KMS encryption key or choose an AWS managed key for encryption.
4. 2.

   Migrate data from unencrypted to encrypted EBS volumes:

   • Create a snapshot of the unencrypted EBS volume.
   • Create a new encrypted EBS volume using the snapshot as the source.
   • Attach the newly created encrypted EBS volume to the instance.
   • Validate the data integrity after migration.

Command Line Interface (CLI) Commands:

2. 1.

   Check Encryption Status for EBS Volumes:

   aws ec2 describe-volumes --query "Volumes[?Encrypted==\`false\`]"
   

4. 2.

   Enable Encryption for EBS Volumes:

   aws ec2 create-encrypted-snapshot --source-volume-id <unencrypted_volume_id> --encrypted true --kms-key-id <kms_key_id>
   

   Note: Replace

   <unencrypted_volume_id>

   with the ID of the unencrypted EBS volume and

   <kms_key_id>

   with the desired AWS KMS key ID.

6. 3.

   Create Encrypted EBS Volume from Snapshot:

   aws ec2 create-volume --snapshot-id <snapshot_id> --encrypted true --kms-key-id <kms_key_id>
   

   Note: Replace

   <snapshot_id>

   with the ID of the snapshot created from the unencrypted EBS volume.

8. 4.

   Attach Encrypted EBS Volume to an Instance:

   aws ec2 attach-volume --volume-id <encrypted_volume_id> --instance-id <instance_id> --device <device_name>
   

   Note: Replace

   <encrypted_volume_id>

   with the ID of the newly created encrypted EBS volume,

   <instance_id>

   with the ID of the instance to attach the volume, and

   <device_name>

   with the desired device name (e.g.,

   /dev/sdf

   ).
