ECS Fargate Security Best Practices

ECS Fargate is a compute service that enables you to run containers without having to manage servers or clusters. Fargate uses Amazon Elastic Container Service (ECS) to manage the underlying compute resources.

You can get a playbook on how to respond to security incidents in Kubernetes environments here.

When you create a Fargate task, you specify an image to use and declare the CPU and memory required. Fargate then launches the task on an appropriate compute resource. You can use Fargate to run containers on on-premises instances, AWS instances, or instances in other clouds.

The following best practices can help you protect your applications and data when using Fargate.

1. Use Security Groups to Restrict Access to Your Fargate Tasks

You can use security groups to restrict access to your Fargate tasks. Security groups allow you to control access to your tasks based on IP addresses or security group membership.

When you create a security group, you can specify the following:

• The source IP addresses or security groups that are allowed to access the task.

• The destination IP addresses or security groups that are allowed to send traffic to the task.

• The type of traffic that is allowed (inbound or outbound).

You can use security groups to restrict access to your Fargate tasks. Security groups allow you to control access to your tasks based on IP addresses or security group membership.

2. Use an IAM Role to Grant Permissions to Your Fargate Tasks

You can use an IAM role to grant permissions to your Fargate tasks. An IAM role allows you to specify the permissions that a task requires.

When you create an IAM role, you can specify the following:

• The Amazon Resource Names (ARNs) of the security groups that are allowed to access the task.

• The type of traffic that is allowed (inbound or outbound).

• The Amazon Resource Names (ARNs) of the security groups that are allowed to send traffic to the task.
