AWS IAM user has administrative privileges
Description
This rule ensures that none of your IAM users have highly privileged policies or administrative policies attached to them.
Rationale
An IAM user with highly privileged or administrative permissions can access all AWS services and resources in the account. A user with these privileges could potentially, whether unknowingly or purposefully, cause security issues or data leaks. Users with these level of access may also be targeted by an adversary to compromise the entire AWS account.
From the console
Follow the Removing a permissions policy from a user docs to revoke policies from a user.
From the command line
Run list-users to get a list of current IAM users.
Run the list-user-policies command find the users attached policies.
aws iam list-user-policies --user-name Name
Run the detach-user-policy command to remove policies from the user.
aws iam detach-user-policy \
--user-name insert-username-here \
--policy-arn insert-policy-arn-here
