Valid from Pega Version 8.3

Pega Platform™ now notifies you of Java injection vulnerabilities in activities, functions, and stream rules at design time and at run time.  You can customize Pega Platform to check for additional vulnerabilities to ensure that your application runs without problems.

For more information, see Configuring the Java injection check.

Valid from Pega Version 8.3

Admin Studio offers a variety of usability enhancements, including:

  • New access groups to differentiate between full and read-only access to Admin Studio
  • A Java class lookup utility
  • A requestor list for the logged-on operator
  • The ability to display system node type in the logs

Also, if your environment uses Predictive Diagnostic Cloud (PDC), the Admin Studio overview page now includes a link to PDC.

For more information, see Managing requestors.

Valid from Pega Version 8.4

You can now access external APIs by using the new OAuth 2.0 JSON Web Token (JWT) Bearer grant type, in an OAuth 2.0 authentication profile. To use the JWT Bearer grant type as a client assertion, source the JWT from an active SSO session, a token profile, or a property reference. You can use JWTs that you obtain during an OpenID Connect SSO in connectors, to achieve user impersonation flows, such as the On-Behalf-Of (OBO) flow. The OAuth 2.0 type authentication profile now also supports authentication of client applications by using Private Key JWTs.

Instances of the OAuth 2.0 provider are now deprecated. As a best practice, use the new, unified authentication profile configuration instead.

For more information, see Configuring an OAuth 2.0 authentication profile.

Upgrade impact

After an upgrade to Pega Platform 8.4 and later, Authentication Profiles can take advantage of the new JWT based OAuth 2.0 grant type and client authentication features. To take advantage of this and other new security features, you must update any existing Authentication Profiles formats must to use those in Pega Platform 8.4 and later.

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

Since these features are available only for profiles created in Pega Platform 8.4 and later, clients must open and then save existing 'Authentication Profile' instances to ensure that the configuration is compatible with the latest authentication formats.

Valid from Pega Version 8.4

You can now authenticate using JSON Web Token (JWT) token profiles to symmetrically and asymmetrically encrypt both signatures and content. All algorithms in the Nimbus JWT library are supported, including nested tokens. Custom key identifier headers (kid) are also supported. Use token profiles to securely propagate identities and transfer data between systems.

For more information, see Creating a processing JSON Web token profile.

For more information, see Creating a generation JSON Web token profile.

Valid from Pega Version 7.3.1

The security checklist is now automatically added to applications. You can manually add the security checklist to applications that were created in earlier versions.

You can improve the security of your application by completing the tasks on the checklist.

The following task reflects the procedure on how to manually add the security checklists to Designer Studio prior to 7.3.1:

  1. In the header of Designer Studio, click the name of the application, and then click Definition.
  2. Click the Documentation tab.
  3. In the Application guides section, click Add guide.
  4. In the Application guide& field, enter pxApplicationSecurityChecklist.
  5. Click the Configure icon in the Available in column and select the portals (App Studio and Dev Studio) that you want to add the security checklist to.
  6. Click Save.

Valid from Pega Version 8.5

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.

Valid from Pega Version 8.5

Increase the security of user sessions by using the newly supported Token Introspection and Denylist services for OAuth 2.0.

Token Introspection service

Use the Token Introspection service to validate JSON Web Tokens (JWT). The Token Introspection service requires authentication. 

Pega now uses OAuth 2.0 access tokens called Authorized Access Tokens (AAT). 

Token Introspection service endpoint

The Token Introspection service endpoint provides the information about the status of access token and refresh token. Token introspection can be used to validate if a given token is still active or inactive. The token introspection endpoint determines whether the token is valid. The status indicates whether an access token or refresh token is valid or invalid: 

  • Valid tokens have the “active”:true status
  • Invalid tokens have the “active” :false status.

The inactive status can also be due to revocation. 

Token Denylist service

You can add tokens to the deny list in cases where suspicious activity might have occurred. The Token Denylist service provides a method for denying user access to the application by revoking the user's access token. This service can prevent a token from being used more than the specified number of times, which can be helpful in preventing replay attacks. Stolen tokens should be revoked using this service. A GET API is also available to get the list of denied tokens.

Keys endpoint

Pega Platform™ is changing from using opaque tokens to JSON Web (JWT) tokens. If this JWT is used by any other system, the public key is needed for signature verification. A new endpoint is exposed to provide these public keys in JWK format: https://host:port/prweb/api/oauth2/v1/token/keys.

 

For more information, see OAuth 2.0 Management Services.

Valid from Pega Version 8.5

You now have more precise control over your refresh token expiration strategy. When a refresh token is enabled, you can choose to set its initial expiration based on the value provided by the IDP. The refresh token expiry can be derived from IDP’s session timeout when SSO is used with external IDP for user authentication in the authorization code grant flow. You can also specify a separate refresh token expiration strategy based on your use-case. 

These can be configured in the OAuth2 Client registration rule form.

For more information, see Enhanced refresh token strategy.

Valid from Pega Version 8.5

Pega Platform™ uses OAuth 2.0 authorization codes, access tokens, and refresh tokens to provide flexible token-based security for applications. Expiration settings for these codes and tokens now adhere to certain strict value range based on industry leading practices. For example, the lifetime specified for the authorization code must be in the range 1-600 seconds.

These can be configured in the OAuth2 Client registration rule form.

For more information, see OAuth 2.0 Management Services.

Valid from Pega Version 8.5

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.
