AWSOverview
Overview
Use secure listeners to support encrypted communication between clients and your load balancers. You can use AWS Certificate Manager (ACM) or AWS Identity and Access Management (IAM) to manage the server certificates installed on your load balancer. You can use the Server Name Indication (SNI) protocol to serve multiple secure websites using a single secure listener. SNI is automatically enabled for your load balancer when you associate more than one server certificate with a secure listener.
Remediation guidance
AWS remediation
Console
- Open ALB listeners.
- Add HTTPS listener on port 443.
- Attach ACM/IAM certificate.
- Redirect HTTP to HTTPS.
AWS CLI
aws elbv2 create-listener \
--load-balancer-arn <alb-arn> \
--protocol HTTPS \
--port 443 \
--certificates CertificateArn=<acm-certificate-arn> \
--default-actions Type=forward,TargetGroupArn=<target-group-arn>

Multiple Remediation Paths
AWS
SERVICE-WIDE (RECOMMENDED when many resources are affected): Deploy centralized guardrails and remediation using AWS Config Conformance Packs and (if applicable) AWS Organizations SCPs.
aws configservice put-organization-conformance-pack --organization-conformance-pack-name <pack-name> --template-s3-uri s3://<bucket>/<template>.yaml
ASSET-LEVEL: Apply the resource-specific remediation steps above to only the affected assets.
PREVENTIVE: Add CI/CD policy checks (CloudFormation/Terraform validation) before deployment to prevent recurrence.

Operational Rollout Workflow
Use this sequence to reduce risk and avoid repeated drift.
1. Contain at Service-Wide Scope First (Recommended)
- AWS: deploy/adjust organization conformance packs and policy guardrails.
aws configservice put-organization-conformance-pack --organization-conformance-pack-name <pack-name> --template-s3-uri s3://<bucket>/<template>.yaml
2. Remediate Existing Affected Assets
- Execute the control-specific Console/CLI steps documented above for each flagged resource.
- Prioritize internet-exposed and production assets first.
3. Validate and Prevent Recurrence
- Re-scan after each remediation batch.
- Track exceptions with owner and expiry date.
- Add preventive checks in IaC/CI pipelines.
Query logic
These are the stored checks tied to this control.
