Ensure no 'root' user account access key exists

높음레벨 1수동 검토aws

설명

The 'root' user account is the most privileged user in an AWS account. AWS access keys provide programmatic access to a given AWS account. It is recommended that all access keys associated with the 'root' user account be deleted. Deleting access keys associated with the 'root' user account limits the vectors by which the account can be compromised. Additionally, removing 'root' access keys encourages the use of role-based access with least privilege.
