Tips: Best Practices for The Other AWS API Gateway Resources

In addition to the aws_api_gateway_method_settings, AWS API Gateway has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.

risk-label

aws_api_gateway_method_settings

Ensure that API Gateway stage-level cache is encrypted

It is better to enable the stage-level cache encryption which reduces the risk of data leakage.

risk-label

aws_api_gateway_domain_name

Ensure to use modern TLS protocols

It is better to adopt TLS v1.2+.

risk-label

aws_api_gateway_stage

Ensure to enable access logging of your API Gateway stage (v1)

It is better to enable the access logging of your API Gateway stage (v1).

risk-label

aws_api_gateway_method

Ensure that your API Gateway method blocks unwanted access

It is better that the API Gateway method does not allow public access.

Review your AWS API Gateway settings

In addition to the above, there are other security points you should be aware of making sure that your .tf files are protected in Shisho Cloud.
