The templates will create a few IAM roles and policies in order
               to work properly. Also, the templates will create
               management roles for Cloud One File Storage Security
               to manage the deployed resources. Cloud One File
               Storage Security allow users to control the created
               permissions.
Warning: Cloud One File Storage Security still requires basic permissions to work. Make sure you allow the required permissions.
Control permissions with permissions boundary
The 
PermissionsBoundary
                  parameter allows users to specify a managed policy
                  ARN as a permissions boundary. This will limit the
                  maximum number of permissions that the IAM roles
                  created by the Cloud One File Storage Security can
                  have.See Permissions boundaries for IAM entities
                  for more details.
Control permissions with additional policies
The 
AdditionalIAMPolicies
                  parameter allows users to specify a
                  comma-delimited list of managed policy ARNs. This
                  list can be attached to the IAM roles created by
                  the Cloud One File Storage Security.
