Go to https://policysim.aws.amazon.com, or click the link on the IAM console under “Additional Information.” Specify a new policy or choose an existing set of policies from a user, group, or role that you’d like to evaluate. Then select a set of actions from the list of AWS services, provide any required information to simulate the access request, and run the simulation to determine whether the policy allows or denies permissions to the selected actions and resources. To learn more about the IAM policy simulator, watch our Getting Started video or see the documentation.
