Published Release Notes

Improving basic access control

Pega Platform™ has implemented a new basic access control (BAC) to protect your application from unauthorized server calls from otherwise authenticated users.

For more information, see Access Control Checks.

Upgrade impact

After you upgrade to Pega 8.5, all the functionality in the model configurations that use auto-generated controls and actions continues to work as before. However, you must secure any customized JavaScript in your application layer that makes AJAX (server) calls  by using registration or encryption mechanisms.

What steps are required to update the application to be compatible with this change?

After upgrade, to migrate custom JavaScript functionality, see Access Control Checks.

Discovery features for access control policies

Access control policies now support discovery features that allow end users to view limited, customizable information about class instances that fail Read policies but satisfy Discover policies. Two types of Discovery gadgets are provided, and when discovery features are enabled, a Discovery gadget is included in the Report Viewer and in search results. Developers can customize these gadgets and include them in other parts of an application user interface.

For more information, see Discovery features for access control policies.

Update and delete actions available in access control policies

Access control policies support update and delete actions on objects. These actions control which specific instances of a class can be created, updated, or deleted by an end user in a case.

For more information, see Creating an access control policy.

Conditional filter logic supported in access control policy conditions

In the Access Control Policy Condition rule form, you can now add conditional logic that allows you to apply different access control policy conditions based on different situations, such as different types of users. The policy condition filters that are enforced  are based on the results of Access When rules. Conditional filters can be configured to allow certain highly privileged users to bypass access control security in certain situations. This is accomplished by entering an Access When but leaving the conditional logic field blank.  When such a filter is applied to a read access policy it also should be applied to the corresponding discover policy.

For more information, see Creating an access control policy condition.

New JWT access token format: Authorized Access Token

Pega Platform™ is changing from using opaque tokens to using JSON Web (JWT) tokens and the JWT access token format: Authorized Access Token (AAT). An AAT enables a client application to validate the server for user permissions and authorizes a specific application to access specific parts of a user’s data.

The major benefits to using the JWT format are:

• The JWT is a self-contained token that has authentication information, expire time information, and other user-defined claims digitally signed.
• A single token can be used with multiple applications.
• The tokens are short-lived and can minimize damage if transport security is compromised, as the token signature is verified.
• As the token is verified with the signature, there is no need to verify against a database, thus reducing latency (usually important for Web APIs).

For more information, see Understanding authorized access tokens.

Control group configuration for predictions

You can now configure a control group for your predictions in Prediction Studio. Based on the control group, Prediction Studio calculates a lift score for each prediction that you can later use to monitor the success rate of your predictions.

For more information, see Customizing predictions.

Improved access to Cosmos UI settings

The Settings tab in the App Studio case designer now includes tools for configuring Cosmos UI. With this enhancement, you can adjust design system settings without the need to specialize individual When rules in Dev Studio, which simplifies UI creation and saves development time.

For more information, see Managing Cosmos UI settings in case designer.

Ability to restrict access to the Import wizard

You can now restrict access to the Import wizard so that users implement an automated pipeline to deploy changes between environments such as staging and production. Deployment Manager is one method by which to create pipelines. By using pipelines to propagate changes, users can apply a standardized and automated deployment process for migrating their applications.

For more information, see:

• Ensuring that users migrate applications with a pipeline by restricting the Import wizard
• Understanding model-driven DevOps with Deployment Manager

Update access groups from the command line

Remotely update access groups by using the prpcServiceUtils tool. This feature is useful in automated deployment scenarios when you want to provide access to a new application version.

For more information, see Updating access groups from the command line.

Custom DX API attributes for auto-generated controls

Auto-generated controls now include the option to add custom attributes for use with the Pega Digital Experience (DX) API. The attributes are part of the DX API response to the front end and you can use them to modify the run-time behavior of the UI elements in your application. For example, you can add an attribute to a field that displays a tooltip text for that field at run time. This enhancement introduces significant flexibility to application development and gives you greater control over UI components.

For more information, see Adding custom attributes for version 1 DX API to auto-generated controls.
