Configure MFA for AWS IAM Users

Overview

Configure Multi-Factor Authentication (MFA) for your AWS Identity and Access Management (IAM) users to enhance account security. This plan assesses current MFA configurations, guides you in selecting MFA preferences, sets up the MFA devices, and ensures accuracy through validation.

Execution Details

Assessment Phase - Gather All Input

1. Identify All IAM Users
   Gather a comprehensive list of all IAM users in your account to serve as the foundation for configuring MFA.

2. Collect MFA Preferences
   For each identified target user, you'll select an MFA method: Software MFA, Hardware MFA, or FIDO Security Key.

Configuration Phase - Set Up MFA for Users

1. Virtual MFA Setup Instructions
   Provide step-by-step guidance for users chosen to use Software MFA to configure their devices via the AWS Management Console.

2. Collect Hardware MFA Codes
   Collect necessary details to enable Hardware MFA devices by gathering authentication codes for target IAM users.

3. Enable Hardware MFA
   Execute commands to bind hardware MFA devices to the specified IAM accounts, confirming successful configuration.

4. FIDO Security Key Setup
   Guide users through the registration process of FIDO Security Keys in the AWS Management Console for those who selected this option.

Validation Phase - Confirm MFA Configuration

1. Verify MFA Setup
   Run checks for each target IAM user to ensure MFA devices are configured correctly, identifying any users missing an active MFA setup for further follow-up.

By following this structured plan, you ensure all IAM users are secured with appropriate MFA methods, enhancing the overall security posture of your AWS environment.
