info

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

Prerequisites

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

Directions

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

    > search is(aws_iam_user) {access_keys[]: --> is(access_key)} access_keys[0].reported.access_key_status=="Active" and access_keys[1].reported.access_key_status=="Active"
    ​kind=aws_iam_user, ..., region=resoto-poweruser
    ​kind=aws_iam_user, ..., account=poweruser-team
  2. Pipe the search command into the dump command:

    > search is(aws_iam_user) {access_keys[]: --> is(access_key)} access_keys[0].reported.access_key_status=="Active" and access_keys[1].reported.access_key_status=="Active" | dump
    ​reported:
    ​ id: /aws/iam/123
    ​ name: some-name
    ​ ctime: '2022-12-05T22:53:14Z'
    ​ kind: aws_iam_user
    ​ age: 2mo28d

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

  3. Fix detected issues by following the remediation steps:

    • Remove the second active access key and only use one.
    • Avoid using long-lived access keys altogether.
    note
