To restrict the contractor’s IAM account access to the EC2 console without providing access to any other AWS services, the security engineer should do the following:

Create an IAM permissions boundary policy that allows EC2 access. This is a policy that defines the maximum permissions that an IAM entity can have.

Associate the contractor’s IAM account with the IAM permissions boundary policy. This means that even if the contractor’s IAM account is assigned additional permissions based on IAM group membership, those permissions are limited by the permissions boundary policy.
