To minimize the risk of unauthorized access to your AWS services, it's crucial to grant appropriate permissions to your Amazon IAM roles. It's important to avoid overly permissive policies and adhere to IAM security best practices, such as implementing the Principle of Least Privilege. This principle ensures that every identity, process, or system is granted only the minimum necessary permissions to perform its required tasks, also known as the principle of least authority. Therefore, it's essential to configure the policies attached to your IAM roles in a way that follows this principle.
