Access Management 7.3.1

Resource types in the UI

You manage resource types through the AM admin UI. Go to Realms > Realm Name > Authorization > Resource Types.

To…​ Action

Create a resource type

Click New Resource Type.

When creating a resource type, specify at least one action and one pattern.

Modify a resource type

Click the resource type name or the pencil icon ().

Delete a resource type

Click the delete icon () or click the resource type name then the x Delete button.

The AM admin UI prevents deletion if any policies or policy sets depend on the resource type.

Resource type names

Do not use any of the following characters in policy, policy set, or resource type names:

Double quotes (")
Plus sign (+)
Comma (,)
Less than (<)
Equals (=)
Greater than (>)
Backslash (\)
Forward slash (/)
Semicolon (;)
Null (\u0000)

Resource type patterns

Policies apply to resources that match their patterns.

  • A policy belongs to a policy set.

  • A policy set permits one or more resource types in their policies.

  • A policy can only define patterns that fit the patterns of its resource types.

Wildcards

Resource type patterns can include a mix of literal characters and wildcards, * or -*- by default. Wildcards can appear anywhere in a resource type pattern to match resources, such as URLs or OAuth 2.0 scopes.

  • Do not mix * and -*- in the same pattern.

  • Wildcards cannot be escaped.

  • By default, comparisons are not case-sensitive.

    To configure the delimiter, wildcards, and case-sensitivity, in the AM admin UI, go to Configure > Global Services > Policy Configuration, and edit the Resource Comparator.

Wildcards in schemes, hosts, and port numbers

When using wildcards for the scheme and authority parts of a URL:

  • The pattern *://*:*/* matches these URLs:

    http://www.example.com:80/index.html
    https://www.example.com:443/index.html
    http://www.example.net:8080/index.html

  • Omitting the port number implies the default port number for the scheme:

    http://www.example.com/* is the same as http://www.example.com:80/*.

    https://www.example.com/* is the same as https://www.example.com:443/*.

Wildcards in paths

Wildcards have these properties in a URL path:

  • The wildcard * matches multiple path segments.

    For example, https://www.example.com/* matches https://www.example.com/, https://www.example.com/index.html, and https://www.example.com/company/images/logo.png.

  • The wildcard -*- matches a single path segment.

    For example, https://www.example.com/-*- matches https://www.example.com/index.html.

    It does not match https://www.example.com/company/resource.html or https://www.example.com/company/images/logo.png.

  • Duplicate slashes (//) count as a single slash.

    http://www.example.com//path/ and http://www.example.com/path// are equivalent.

  • A trailing slash counts as a distinct part of the resource to match.

    https://www.example.com/path and https://www.example.com/path/ are not equivalent.

Wildcards in query strings

Wildcards do not match ?.

Add explicit patterns to match URLs with query strings:

  • When matching URLs protected by a web or Java agent, an asterisk (*) at the end of a pattern after ? matches one or more characters, not zero or more characters.

    For example, https://www.example.com/*?* matches https://www.example.com/users?_action=create, not https://www.example.com/users?.

    To match all URLs under https://www.example.com/, specify three patterns:

    https://www.example.com/*
    https://www.example.com/*?
    https://www.example.com/*?*

  • When matching resources with a policies?_action=evaluate REST call, an asterisk (*) at the end of a pattern after ? matches zero or more characters.

    For example, https://www.example.com/*?* matches https://www.example.com/users?_action=create and https://www.example.com/users?.

    To match all URLs under http://www.example.com/, specify two patterns:

    https://www.example.com/*
    https://www.example.com/*?*

  • AM normalizes query strings before checking whether a policy matches a resource.

    To normalize the query string, AM sorts the query string field-value pairs alphabetically by field name. These query strings are equivalent:

    ?subject=SPBnfm+t5PlP+ISyQhVlplE22A8=&action=get
    ?action=get&subject=SPBnfm+t5PlP+ISyQhVlplE22A8=

Non-ASCII characters

Use percent-encoding for non-ASCII characters in resource patterns.

For example, to match resources under the Internationalized Resource Identifier (IRI) https://www.example.com/forstå/ use:

https://www.example.com:443/forst%C3%A5/*
https://www.example.com:443/forst%C3%A5/*?*

Resource type actions

AM policies use actions to grant or deny access to a resource. A policy can only determine actions defined by its resource types.

Choose a name that summarizes the action the principal aims to perform on the resource. The default state for each action is either Allow or Deny.

Example

The following screen creates a resource type for policies to switch lights on and off:

Add the patterns and actions that policies using this resource type can make use of.
