This account has complete, unrestricted access to all AWS services and resources. However, AWS strongly recommends limiting root user access due to its powerful nature. There are specific tasks that can ONLY be performed by the root user, making it essential to understand these exclusive capabilities.
**Root User Exclusive Tasks Include:**
1. **Changing Account Settings** - Modifying the account name, email address, root user password, and root user access keys.
2. **Restoring IAM User Permissions** - If an IAM administrator accidentally revokes their own permissions, only the root user can restore them.
3. **Activating IAM Access to Billing** - Enabling IAM users and roles to access billing and cost management console requires root credentials.
4. **Closing the AWS Account** - Only the root user can permanently close an AWS account.
5. **Changing AWS Support Plans** - Upgrading or downgrading support plans requires root access.
6. **Registering as a Seller in Reserved Instance Marketplace** - This marketplace activity is exclusive to root users.
7. **Configuring S3 Bucket with MFA Delete** - Enabling MFA delete on S3 buckets requires root credentials.
8. **Editing or Deleting S3 Bucket Policies with Invalid VPC IDs** - Correcting these policies requires root access.
9. **Signing up for GovCloud** - Registration for AWS GovCloud requires root user credentials.
**Best Practices:**
- Enable Multi-Factor Authentication (MFA) on the root account
- Create strong passwords
- Avoid using root for everyday tasks
- Create IAM users with appropriate permissions for daily operations
- Store root credentials securely
- Regularly audit root account usage through CloudTrail
Understanding these exclusive tasks helps organizations maintain proper security governance while ensuring critical administrative functions remain accessible when needed.
Root User Exclusive Tasks in AWS
What is the AWS Root User?
The AWS root user is the identity that is created when you first set up an AWS account. It is accessed using the email address and password used to create the account. The root user has complete and unrestricted access to all resources in the AWS account, making it the most powerful identity in your AWS environment.
Why is Understanding Root User Exclusive Tasks Important?
Understanding root user exclusive tasks is critical for several reasons:
1. Security Best Practices: AWS strongly recommends not using the root user for everyday tasks. Knowing which tasks require root access helps you minimize root user usage.
2. Compliance Requirements: Many compliance frameworks require limiting root user access and documenting when it must be used.
3. Exam Relevance: The AWS Cloud Practitioner exam frequently tests your knowledge of what tasks can only be performed by the root user.
Tasks That ONLY the Root User Can Perform:
• Change account settings - This includes the account name, email address, root user password, and root user access keys
• Close an AWS account - Only the root user can permanently close the entire AWS account
• Restore IAM user permissions - If the only IAM administrator accidentally revokes their own permissions, root user must restore them
• Change or cancel AWS Support plans - Upgrading or downgrading support plans requires root access
• Register as a seller in the Reserved Instance Marketplace
• Configure an S3 bucket to enable MFA Delete
• Edit or delete an S3 bucket policy that includes an invalid VPC ID or VPC endpoint ID
• Sign up for GovCloud
• View certain tax invoices
How Root User Security Works:
AWS implements several security measures for root user protection:
1. Multi-Factor Authentication (MFA): AWS strongly recommends enabling MFA on the root account to add an extra layer of security.
2. Access Keys: AWS recommends deleting root user access keys. If they exist, they should be rotated regularly.
3. Limited Usage: Use IAM users and roles for daily operations instead of the root user.
Best Practices for Root User Management:
• Enable MFA on the root user account • Do not create access keys for the root user • Use a strong, unique password for the root user • Create individual IAM users for administrative tasks • Store root user credentials securely • Use the root user only when absolutely necessary
Exam Tips: Answering Questions on Root User Exclusive Tasks
1. Memorize the exclusive tasks: Know the specific tasks that can only be done by root user, especially closing accounts, changing account-level settings, and modifying support plans.
2. Watch for keywords: Questions mentioning 'account closure,' 'support plan changes,' or 'account email/name changes' typically point to root user as the answer.
3. Security-focused questions: If asked about best practices, remember that root user should rarely be used and should always have MFA enabled.
4. Elimination strategy: If a question asks what an IAM administrator can do, eliminate root-user-exclusive tasks from your options.
5. Billing and account management: Tasks related to fundamental account settings almost always require root user access.
6. Common distractors: Creating IAM users, managing EC2 instances, or configuring services are NOT root-exclusive tasks - these can be delegated to IAM users with appropriate permissions.
7. Remember the principle: Root user is for account-level tasks that affect the entire AWS account, not for resource management within the account.
