Ensure that an inline IAM role policy does not allow full administrative rights

IAM role policy should be setup in such a way that it follows the least privilege principle. Allowing full admin rights may result into critical security loopholes in the system.

IAM Role

An IAM role is similar to a user, in that it is an AWS identity with permission policies that determine what the identity can and cannot do in AWS. However, instead of being uniquely associated with one person, a role is intended to be assumable by anyone who needs it. Also, a role does not have standard long-term credentials (password or access keys) associated with it. Instead, if a user assumes a role, temporary security credentials are created dynamically and provided to the user.
