Security

When you build systems on AWS infrastructure, security responsibilities are shared between you and AWS. This shared model can reduce your operational burden as AWS operates, manages, and controls the components from the host operating system and virtualization layer down to the physical security of the facilities in which the services operate. For more information about security on AWS, visit AWS Cloud Security.

IAM roles

AWS Identity and Access Management (IAM) roles allow customers to assign granular access policies and permissions to services and users on AWS. This solution creates several IAM roles, including roles that grant the solution's AWS Lambda function access to the other AWS services used in this solution.

Amazon CloudFront

This solution deploys a static website hosted in an Amazon Simple Storage Service (Amazon S3) bucket. To help reduce latency and improve security, this solution includes an Amazon CloudFront distribution with an origin access identity, which is a special CloudFront user that helps provide secure, public access to the solution’s website bucket contents. For more information, see Restricting Access to Amazon S3 Content by Using an Origin Access Identity.

AWS Fargate security group

By default, this solution opens the outbound rule of the AWS Fargate security group to the public. If you want to block AWS Fargate from sending traffic to everywhere, then change the outbound rule to a specific Classless Inter-Domain Routing (CIDR).

This security group also includes an inbound rule that allows local traffic on port 50,000 to any source that belongs to the same security group. This is used to allow the containers to communicate with one another.

Network stress test

You are responsible for using this solution under the Network Stress Test policy. This policy covers situations such as if you are planning on running high volume network tests directly from your Amazon EC2 instances to other locations such as other Amazon EC2 instances, AWS properties/services, or external endpoints. These tests are sometimes called stress tests, load tests, or gameday tests. Most customer testing will not fall under this policy, however, refer to this policy if you believe you will be generating traffic that sustains, in aggregate, for more than 1 minute, over 1 Gbps (1 billion bits per second) or over 1 Gpps (1 billion packets per second).

Restricting access to the public user interface

To restrict access to the public-facing user interface beyond the authentication and authorization mechanisms provided by IAM and Amazon Cognito, use the AWS WAF (web application firewall) Security Automations solution.

This solution automatically deploys a set of AWS WAF rules that filter common web-based attacks. Users can select from preconfigured protective features that define the rules included in an AWS WAF web access control list (web ACL).
