How to Find AWS IAM multi-factor authentication (MFA) not enabled for all users that have a console password

Problem​

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

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) and password_enabled==true and mfa_active==false
    ​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) and password_enabled==true and mfa_active==false | 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:

    • Enable MFA for users account.
    • MFA is a simple best practice that adds an extra layer of protection on top of your user name and password.
    • Recommended to use hardware keys over virtual MFA.
    note
