Ensure that assignPublicIp is set to DISABLED for Amazon ECS task sets, to prevent task sets from being publicly accessible.
Enabling public IP assignment could expose task sets 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.
No specific console audit steps provided. Use the CLI audit procedure below.
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 task sets for a service:
aws ecs describe-task-sets --cluster <cluster-arn> --service <service-arn>
For each task set, 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 task sets.
No specific console remediation steps provided. Use the CLI or update the service/task set configuration directly.
No specific CLI remediation command provided. Task sets are typically managed through service deployments. Update the service configuration to ensure new task sets use assignPublicIp set to DISABLED.
By default, assignPublicIp is set to ENABLED.
