[[_resource_server_default_config]]
=== Default Configuration

When you create a resource server, {{book.project.name}} creates a default configuration for your newly created resource server.

The default configuration consists of:

* A default protected resource representing all resources in your application.
* A policy that always grants access to the resources protected by this policy.
* A permission that governs access to all resources based on the default policy.

The default protected resource is referred to as the *default resource* and you can view it if you navigate to the *Resources* tab.

.Default Resource
image:../../{{book.images}}/resource-server/default-resource.png[alt="Default Resource"]

This resource defines a `Type`, namely `urn:my-resource-server:resources:default` and a `URI` `/*`. Here, the `URI` field defines a
wildcard pattern that indicates to {{book.project.name}} that this resource represents all the paths in your application. In other words,
when enabling <<fake/../../enforcer/overview.adoc#_enforcer_overview, policy enforcement>> for your application, all the permissions associated with the resource
will be examined before granting access.

The `Type` mentioned previously defines a value that can be used to create <<fake/../../permission/typed-resource-permission.adoc#_permission_typed_resource, typed resource permissions>> that must be applied
to the default resource or any other resource you create using the same type.

The default policy is referred to as the *only from realm policy* and you can view it if you navigate to the *Policies* tab.

.Default Policy
image:../../{{book.images}}/resource-server/default-policy.png[alt="Default Policy"]

This policy is a <<fake/../../policy/js-policy.adoc#_policy_js, JavaScript-based policy>> defining a condition that always grants access to the resources protected by this policy. If you click this policy you can see that it defines a rule as follows:

```js
// by default, grants any permission associated with this policy
$evaluation.grant();
```

Lastly, the default permission is referred to as the *default permission* and you can view it if you navigate to the *Permissions* tab.

.Default Permission
image:../../{{book.images}}/resource-server/default-permission.png[alt="Default Permission"]

This permission is a <<fake/../../permission/create-resource.adoc#_permission_create_resource, resource-based permission>>, defining a set of one or more policies that are applied to all resources with a given type.

==== Changing the Default Configuration

You can change the default configuration by removing the default resource, policy, or permission definitions and creating your own.

[NOTE]
The default configuration defines a resource that maps to all paths in your application. If you are about to write permissions to your own resources, be sure
to remove the *Default Resource* or change its ```URI``` field to a more specific path in your application. Otherwise, the policy associated with the default resource (which by default is always granting access)
will make Keycloak grant access to any protected resource.
