Authentication nodes and journeys

Authentication journeys provide fine-grained authentication by allowing multiple paths and decision points throughout the authentication flow. Use them to build complex authorization scenarios, while offering a streamlined login experience to users.

Authentication journeys are made up of authentication nodes, which define actions taken during authentication. Each node performs a single task during authentication; for example, collecting a username or making a simple decision based on a cookie.

Nodes can have multiple outcomes rather than just success or failure. These outcomes let you create complex yet user-friendly authentication experiences by linking nodes together, creating loops and sections for different authentication scenarios, and nesting nodes within a journey.

Create multiple paths for authentication by linking nodes within journeys.

Figure 1. Example authentication journey

For greater control of the authentication process, you can assign authentication levels to sections of a journey, with higher levels typically allowing access to more restricted resources.

Authentication levels

When a user authenticates successfully, PingOne Advanced Identity Cloud creates a session which allows PingOne Advanced Identity Cloud to manage the user’s access to resources. The session is assigned an authentication level. The authentication level is often used as a measure of the strength of the authentication performed. For example, a simple username and password might be assigned a low authentication level, while multi-factor authentication with push and WebAuthn might be assigned a high level.

Authorization policies might require a particular authentication level to access protected resources. When an authenticated user tries to access a protected resource without satisfying the authentication level requirement, PingOne Advanced Identity Cloud denies access to the resource and returns an advice indicating that the user must reauthenticate at the required level to access the resource.

The policy enforcement point, such as an agent, sends the user back to PingOne Advanced Identity Cloud for a session upgrade.

PingOne Advanced Identity Cloud provides the following nodes to manage authentication levels:

The Auth Level Decision node checks that the current authentication level is equal to or greater than the level specified in the node.
The Modify Auth Level node can raise or lower the authentication level.

Position these nodes to alter the authentication level, depending on the route taken through the authentication flow.

Account lockout

Use account lockout to limit the number of times an end-user can attempt to authenticate with invalid credentials before rendering their account inactive. Limiting the number of attempts helps to prevent password-guessing and brute-force attacks.

Authentication journeys have built-in support for account lockout. They also provide nodes for checking and changing the status of a user.

For more information refer to Account lockout.

Configure authentication journeys

The following table summarizes the high-level tasks required to configure authentication journeys:

Task Resources

Task	Resources
Design your user authentication journey Authentication journeys are flexible. For example, the same journey can branch for different use cases, or users can be forced to loop though branches until they’re able to present the required credentials. It’s easy to create a massive journey that’s difficult to understand, read, and maintain in the UI. To avoid this, PingOne Advanced Identity Cloud lets you nest journeys within journeys. The best way to tackle the design decision is to write down a list of required steps users would need to take to log in to your environment, and then check the list of nodes available in PingOne Advanced Identity Cloud.

Specify the identity object type for a journey

Each authentication journey assumes a specific identity object type. The nodes in the journey use this object type to verify the identity, for example, users, roles, or organizations. The default journeys provided with Advanced Identity Cloud assume the identity object using the journey to authenticate is a realm-name user, for example Alpha realm - Users or Bravo realm - Users.

When you create a new journey, you select the object type in the Identity Object list.

To change the object type of an existing journey:

In the Advanced Identity Cloud admin UI select Journeys > Journey name > Edit.
On the journey page, click the ellipses () at the top right of the page, then click Edit details.
Select a new object type in the Identity Object list.

Enable and disable an authentication journey

Custom authentication journeys are enabled by default, when they are saved. For security purposes, you can disable custom authentication journeys during development and testing, to prevent accidentally allowing access through these journeys. Rather than having unused authentication journeys enabled, you should disable the default authentication journeys until you need them.

When a user attempts to authenticate through a disabled journey, PingOne Advanced Identity Cloud returns a Tree does not exist error.

To enable or disable an authentication journey, set the enabled flag in the journey configuration:

To enable or disable an authentication journey, send a PUT request to update the journey’s configuration. Specify the journey ID, the nodes in the journey, and set the enabled flag:

Disable direct access through a child journey

A child journey lets you nest authentication logic. There is no limit to the depth of nesting.

You configure a child journey like any other journey and call it from a parent journey using an Inner Tree Evaluator node.

You may want to hide child journeys as complete services. In other words, you may want to prevent users from authenticating directly through a child journey, either for security reasons or simply because the child journey is insufficient as a complete authentication service.

To prevent a journey from being used outside of its parent journey, send a PUT request to update the journey configuration, including the journey ID and all the nodes in the journey and set the innerTreeOnly property to true:

Example

$ curl \
--header "Content-Type: application/json" \
--header "<session-cookie-name>: AQIC5..." \
--header 'accept-api-version: protocol=2.1,resource=1.0' \

Configure authentication webhooks

Webhooks are used to send HTTP POST calls to a server with contextual information about an authentication session when a predefined event occurs, for example, logging out.

Webhooks are used from within authentication journeys, by the Register Logout Webhook node.

Under Native Consoles > Access Management, go to Realms > Realm Name > Authentication > Webhooks.
Select Create Webhook, specify a Webhook Name, and select Create.

The webhook configuration screen is displayed:

Complete the fields as required:

Url

The URL to which the HTTP POST is sent when the event occurs.

Body

The body of the HTTP POST. To send different data formats, set the correct Content-Type header in the Header property, for example:

Form Data. Enter the body value in the format parameter=value&parameter2=value2, and set a Content-Type header of application/x-www-form-urlencoded.
JSON Data. Enter the body value in the format {"parameter":"value","parameter2":"value2"}, and set a Content-Type header of application/json.

Headers

Any HTTP headers to add to the POST.

To add a header, enter the name of the header in the Key field, and the value, and then click Add (➕).

To remove a header, click Delete (✖).

The fields in a webhook support variables for retrieving values from the user’s session after successfully authenticating. Specify a variable in the following format: ${variable_name}.

To access the type of webhook event, use the WebhookEventType parameter key to return one of the following possible values:

LOGOUT
UPGRADE
DESTROY
MAX_TIMEOUT
IDLE_TIMEOUT

For example, to retrieve the event type as a query parameter: &event=${WebhookEventType}

You can use a variable to access custom properties added to the session with the Set Session Properties node as well as the following default session properties:
