Enforce TLS 1.2 SSL Policy for AWS EC2 Classic Load Balancer Listeners

Enforce TLS 1.2 SSL Policy for AWS EC2 Classic Load Balancer Listeners

Ensuring that AWS EC2 Classic Load Balancer listeners use SSL policies with TLS 1.2 or greater for any traffic traveling outside of the VPC is crucial for maintaining secure communications. This measure helps in protecting data in transit by enforcing stronger encryption standards, thereby reducing the risk of data breaches and ensuring compliance with security best practices and regulatory requirements.

This policy pack can help you configure the following settings for Classic Load Balancer listeners:

  • Set SSL policy ELBSecurityPolicy-TLS-1-2-2017-01 by default

Documentation

Getting Started

Requirements

Credentials

To create a policy pack through Terraform:

  • Ensure you have Turbot/Admin permissions (or higher) in Guardrails
  • Create access keys in Guardrails

And then set your credentials:

export TURBOT_WORKSPACE=myworkspace.acme.com
export TURBOT_ACCESS_KEY=acce6ac5-access-key-here
export TURBOT_SECRET_KEY=a8af61ec-secret-key-here

Please see Turbot Guardrails Provider authentication for additional authentication methods.

Usage

Install Policy Pack

Note

By 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.git
cd guardrails-samples/policy_packs/aws/ec2/enforce_tls_1_2_ssl_policy_for_classic_load_balancer_listeners

Run the Terraform to create the policy pack in your workspace:

terraform init
terraform plan

Then apply the changes:

terraform apply

Apply 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

Tip

You 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_ec2_classic_load_balancer_listener_ssl_policy" {
resource = turbot_policy_pack.main.id
type = "tmod:@turbot/aws-ec2#/policy/types/classicLoadBalancerListenerSslPolicy"
# value = "Check: Set in SSL Policy > Allowed"
value = "Enforce: Set to SSL Policy > Default"
}

Then re-apply the changes:

terraform plan
terraform apply
