Enforce Encryption in Transit Is Enabled for AWS Redshift Clusters
Enforcing encryption in transit for AWS Redshift clusters is crucial for protecting data as it moves between clients and the Redshift service. This measure ensures that all data is encrypted during transmission, safeguarding it from interception and unauthorized access, thereby enhancing overall security and compliance with best practices and regulatory requirements.
This policy pack can help you configure the following settings for Redshift clusters:
- Enable Encryption in Transit by changing the
require_sslparameter of the attached parameter group. This change will also trigger reboot of the cluster.
Getting Started
Requirements
- Terraform
- The following Guardrails mods need to be installed:
Credentials
To create a policy pack through Terraform:
- Ensure you have
Turbot/Adminpermissions (or higher) in Guardrails - Create access keys in Guardrails
And then set your credentials:
export TURBOT_WORKSPACE=myworkspace.acme.comexport TURBOT_ACCESS_KEY=acce6ac5-access-key-hereexport TURBOT_SECRET_KEY=a8af61ec-secret-key-herePlease see Turbot Guardrails Provider authentication for additional authentication methods.
Usage
Install Policy Pack
NoteBy default, installed policy packs are not attached to any resources.
Policy packs must be attached to resources in order for their policy settings to take effect.
Clone:
git clone https://github.com/turbot/guardrails-samples.gitcd guardrails-samples/policy_packs/aws/redshift/enforce_encryption_in_transit_is_enabled_for_clustersRun the Terraform to create the policy pack in your workspace:
terraform initterraform planThen apply the changes:
terraform applyApply Policy Pack
Log into your Guardrails workspace and attach the policy pack to a resource.
If this policy pack is attached to a Guardrails folder, its policies will be applied to all accounts and resources in that folder. The policy pack can also be attached to multiple resources.
For more information, please see Policy Packs.
Enable Enforcement
TipYou can also update the policy settings in this policy pack directly in the Guardrails console.
Please note your Terraform state file will then become out of sync and the policy settings should then only be managed in the console.
By default, the policies are set to Check in the pack's policy settings. To enable automated enforcements, you can switch these policies settings by adding a comment to the Check setting and removing the comment from one of the listed enforcement options:
resource "turbot_policy_setting" "aws_redshift_cluster_encryption_in_transit" { resource = turbot_policy_pack.main.id type = "tmod:@turbot/aws-redshift#/policy/types/clusterEncryptionInTransit" # value = "Check: Enabled" value = "Enforce: Enabled"}Then re-apply the changes:
terraform planterraform apply
