AWS Redshift instances should be encrypted at rest to help protecting sensitive data from breaches.

Risk Level: High
Cloud Entity: Amazon Redshift
CloudGuard Rule ID: D9.AWS.CRY.34
Covered by Spectral: Yes
Category: Database


Redshift should have dataEncrypted=true


From Portal
Following steps will enable encryption for the desired redshift cluster:

  1. Login to the AWS Management Console.
  2. Navigate to Redshift dashboard at https://console.aws.amazon.com/redshift/.
  3. In the navigation panel, under Redshift Dashboard, click 'Clusters'.
  4. Choose the Redshift cluster that you want to modify encryption settings and click on 'Properties' tab.
  5. Verify the Encryption status (Disabled/enabled) under the Cluster Properties.
  6. Click on 'Edit' tab on the right side and go to edit encryption.
  7. Select the desired encryption type and save it.

From TF

resource "aws_redshift_cluster" "test" {
	cluster_identifier = "tf-redshift-cluster"
	database_name      = "mydb"
	master_username    = "foo"
	master_password    = "Mustbe8characters"
	node_type          = "dc1.large"
	cluster_type       = "single-node"
	+ encrypted          = true

From Command Line
To turn on encryption for Redshift cluster

Amazon Redshift

Amazon Redshift is a fast, fully managed data warehouse that makes it simple and cost-effective to analyze all your data using standard SQL and your existing Business Intelligence (BI) tools. It allows you to run complex analytic queries against petabytes of structured data, using sophisticated query optimization, columnar storage on high-performance local disks, and massively parallel query execution. Most results come back in seconds. With Amazon Redshift, you can start small for just $0.25 per hour with no commitments and scale out to petabytes of data for $1,000 per terabyte per year, less than a tenth the cost of traditional solutions.
