How to Find AWS S3 bucket MFA Delete is not enabled

Problem

Your security credentials are compromised or unauthorized access is granted.

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_s3_bucket) and bucket_mfa_delete=false
    ​kind=aws_s3_bucket, ..., region=resoto-poweruser
    ​kind=aws_s3_bucket, ..., account=poweruser-team
  2. Pipe the search command into the dump command:

    > search is(aws_s3_bucket) and bucket_mfa_delete=false | dump
    ​reported:
    ​ id: /aws/s3/123
    ​ name: some-name
    ​ ctime: '2022-12-05T22:53:14Z'
    ​ kind: aws_s3_bucket
    ​ age: 2mo28d

    The command output will list the details of all non-compliant aws_s3_bucket resources.

  3. Fix detected issues by following the remediation steps:

    • Add MFA delete to an S3 bucket.
    • It requires additional authentication when you change the version state of your bucket, or you delete and object version adding another layer of security in the event your security credentials are compromised or unauthorized access is granted.
    note

    Please refer to the AWS S3 documentation for details.
