Elective controls with detective behavior

The following elective controls have detective behavior.

Detect Whether MFA is Enabled for AWS IAM Users

This control detects whether MFA is enabled for AWS IAM users. You can protect your account by requiring MFA for all AWS users in the account. MFA requires an additional authentication code after the user name and password are successful. This control does not change the status of the account. This is a detective control with elective guidance. By default, this control is not enabled.

The artifact for this control is the following AWS Config rule.

The artifact for this control is the following AWS Config rule.

AWSTemplateFormatVersion: 2010-09-09
Description: Configure AWS Config rules to check whether MFA is enabled for all AWS IAM users that use a console password.
Parameters:
  ConfigRuleName:
    Type: 'String'
