Ensure that assignPublicIp is set to DISABLED for Amazon ECS services, to restrict direct exposure of containers to the public internet.
Enabling public IP assignment could expose container application servers to unintended or unauthorized access.
Disabling assignPublicIp introduces administrative, operational, and potential cost overhead due to the need to configure and maintain private networking and associated resources.
Clusters.Services, click the name of a service.Configuration and networking.Network configuration, ensure Auto-assign public IP is set to Turned off.Run the following command to list clusters:
aws ecs list-clusters
Run the following command to list services in a cluster:
aws ecs list-services --cluster <cluster-arn>
Run the following command to view the details of a service:
aws ecs describe-services --cluster <cluster-arn> --services <service-arn>
Under networkConfiguration > awsvpcConfiguration, ensure assignPublicIp is set to DISABLED.
Repeat for each cluster and service.
assignPublicIp should be set to DISABLED under networkConfiguration > awsvpcConfiguration for all ECS services.
No specific console remediation steps provided. Use the CLI remediation below.
For each service requiring remediation, run the following command to set assignPublicIp to DISABLED:
aws ecs update-service --cluster <cluster-arn> --service <service-arn> --network-configuration '{"awsvpcConfiguration":{"subnets":["<subnet-id>"],"securityGroups":["<security-group-id>"],"assignPublicIp":"DISABLED"}}'
By default, assignPublicIp is set to ENABLED.
