How to Find AWS API Gateway without WAF ACL


Potential attacks and / or abuse of service for internet reachable services.


This security check is part of the CIS Amazon Web Services Benchmarks and is rated severity medium.


This guide assumes that you have already installed and configured Resoto to collect your AWS cloud resources.


  1. Execute the following search command in Resoto Shell or Resoto UI:

    > search is(aws_api_gateway_stage) and stage_web_acl_arn==null
    ​kind=aws_api_gateway_stage, ..., region=resoto-poweruser
    ​kind=aws_api_gateway_stage, ..., account=poweruser-team
  2. Pipe the search command into the dump command:

    > search is(aws_api_gateway_stage) and stage_web_acl_arn==null | dump
    ​ id: /aws/apigateway/123
    ​ name: some-name
    ​ ctime: '2022-12-05T22:53:14Z'
    ​ kind: aws_api_gateway_stage
    ​ age: 2mo28d

    The command output will list the details of all non-compliant aws_api_gateway_stage resources.

  3. Fix detected issues by following the remediation steps:

    Use AWS WAF to protect your API Gateway API from common web exploits, such as SQL injection and cross-site scripting (XSS) attacks. These could affect API availability and performance, compromise security or consume excessive resources.


    Please refer to the AWS API Gateway documentation for details.
