enable-storage-encryption

Default Severity: high

Explanation

Encryption of the underlying storage used by DocumentDB ensures that if their is compromise of the disks, the data is still protected.

Possible Impact

Unencrypted sensitive data is vulnerable to compromise.

Suggested Resolution

Enable storage encryption

Insecure Example

The following example will fail the aws-documentdb-enable-storage-encryption check. 

 resource "aws_docdb_cluster" "bad_example" {
   cluster_identifier      = "my-docdb-cluster"
   engine                  = "docdb"
   master_username         = "foo"
   master_password         = "mustbeeightchars"
   backup_retention_period = 5
   preferred_backup_window = "07:00-09:00"
   skip_final_snapshot     = true
   storage_encrypted = false
 }

Secure Example

The following example will pass the aws-documentdb-enable-storage-encryption check. 

 resource "aws_docdb_cluster" "good_example" {
   cluster_identifier      = "my-docdb-cluster"
   engine                  = "docdb"
   master_username         = "foo"
   master_password         = "mustbeeightchars"
   backup_retention_period = 5
   preferred_backup_window = "07:00-09:00"
   skip_final_snapshot     = true
   storage_encrypted = true
 }
