  'Multi-Factor Authentication (MFA) helps you to prevent credential compromise. This alert identifies logins to the AWS Management Console without MFA.
  You can limit this detection to trigger for administrative accounts if you do not have MFA enabled on all accounts.
  This is done by looking at the eventName ConsoleLogin and if the AdditionalEventData field indicates MFA was NOT used
  and the ResponseElements field indicates NOT a Failure. Thereby indicating that a non-MFA login was successful.'
