Release Notes

This section describes the new features and updates of the Cortex XDR 3.6 and Cortex XDR Agent 8.0 releases.

The Cortex XDR 3.6 and Cortex XDR Agent 8.0 releases includes the following enhancements:

GENERAL

Flexible Next-Gen Firewall and Prisma Access Data Ingestion (Requires a Cortex XDR Pro TB license)

To streamline connection and management of data ingestion, Cortex XDR is no longer dependent on the Cortex Data Lake. 

As of version 3.6, Palo Alto Networks data sources, including Next-generation Firewalls and Prisma Access logs, can be ingested and managed directly in Cortex XDR and you no longer need to connect to the Cortex Data Lake. 

Once your tenant has been activated, navigate to the Collection Integrations page to configure your integrations. Connect your Next-Gen Firewalls directly into XDR, selecting which sources will ingest data into the system. You can do so by connecting a firewall directly or using Panorama.

Session Timeout Enhancements

User interface session timeouts can now be configured to last up to 24 hours. To mitigate security concerns, an inactivity auto-logout has been added.

Cortex Gateway Tenant Renaming

To provide with you greater flexibility, you now have the option in the Cortex Gateway to rename your tenant. Tenant names must be unique and can only be renamed by a user with Instance Admin permissions.

INVESTIGATION AND RESPONSE

New Identity Threat Module

Cortex XDR introduces our advanced Identity Threat Module to provide best-in-class coverage for stealthy identity threat vectors, including compromised accounts and insider threats.

  • New Identity Dashboard for reviewing the risk posture of the organization and allowing faster decision making.

  • New User/Host Risk View, which provides additional information about the asset, including score trend timeline, notable events, peer comparison, and additional asset-associated alerts and insights for easy uncovering of hidden threats.

  • New automated user and host role classification based on constant analysis of their activities. You can adjust these roles at any given time in order to fine-tune the assets associated with each role.

  • New Analytics alert layout that displays profile information for quicker triaging and investigation.

When you log in to Cortex XDR with a Pro license for the first time after the upgrade, Cortex XDR displays a banner that enables you to activate the Identity Threat module. The module is available for a free trial period ending on July 31, 2023. After this date, the module will be available as an Add-on.

XQL to_json_string Function Enhancements

(Requires a Cortex XDR Pro license)

The Cortex XDR Query Language (XQL) to_json_string function now returns the same string when the input to the function is a string. Previously, the function would return a JSON formatted string if the input was a string.

Top Incidents (Top 10) Widget Enhancements

The Top Incidents (Top 10) dashboard widget now includes scores, which can be used to sort the incident list.

SBAC (Scoped-Based Access Control) Support for Incident Configuration Settings

To continue to support scoped-based access control capabilities of alerts and incidents, it has also been applied to incident configuration settings. Based on the tags used to define scope, users now have access to configure the settings for the relevant alerts within their scope. This applies to all scoped users.

Incident Automation Rules and Logs

(Requires a Cortex XDR Pro license)

To enhance Cortex XDR's productivity of day to day tasks, new automation capabilities have been added to endpoint response actions, incident and alert management and external communication (email, slack, syslog) actions.

SmartScore Enhancements

To enhance your triaging and investigation capabilities, SmartScore will now provide scoring enrichment by indicating the main factors contributing to a score.

New Alert Suppression Counters

To improve visibility into alert suppression, Cortex XDR added counters in IOC, BIOC, and Analytics alert side panels which display the number of suppressed alerts and the timestamp of the last suppression for the alert. The counters are displayed for new alerts generated after upgrading to the current version.

EXTERNAL DATA INGESTION

Box, Dropbox, and OneLogin Data Collector Enhancements for Normalizing Logs to Stories

(Requires a Cortex XDR Pro per GB license)

To enhance your investigation capabilities, Cortex XDR now supports normalizing logs into stories, when either a Box, Dropbox, or OneLogin data collector is configured.

Normalization of Kubernetes Audit Logs

(Requires a Cortex XDR Pro per GB license)

To expand the current data ingestion capabilities when collecting Kubernetes audit logs, Cortex XDR now normalizes Kubernetes audit logs (API Server logs) for the following data collectors:

  • AWS:  Includes an option to Normalize audit logs (selected by default) when configuring an Amazon Elastic Kubernetes Service (EKS) log type.

  • Azure Event Hub: Azure Kubernetes Service (AKS) audit logs are automatically normalized when they are included in the logs.

  • Google Cloud Platform: Google Kubernetes Engine (GKE) audit logs are automatically normalized when they are included in the logs.

Okta Data Collector Enhancement to Minimize Repeated API Requests

(Requires a Cortex XDR Pro per GB license)

The Okta data collector in Cortex XDR is now improved to significantly reduce the number of requests made to the Okta API whenever an error is received indicating that too many requests have already been sent. In addition, to ensure you are properly notified about this, an alert is displayed in the Notification Area and a record is added to the Management Audit Logs.

Office 365 Data Collector Supports Collecting Alerts from Microsoft Graph Security API v2 Data Sources

(Requires a Cortex XDR Pro per GB license)

To expand the current data ingestion capabilities of the Office 365 data collector, Cortex XDR now enables you to configure collecting alerts from Microsoft Graph Security API v2 (beta version) data sources, which include alerts from various Microsoft 365 Defender products and Microsoft Purview Data Loss Prevention. This option is now available in addition to the previous option of collecting alerts from Microsoft Graph Security API v1 data sources.

To support this change, the previous option called Alerts from Microsoft Graph Security API is now renamed to Alerts. Select Alerts to collect alerts from Microsoft Graph Security API v1 data sources. To collect alerts from the new Microsoft Graph Security API v2 (beta version) data sources, select Alerts and the new option below called Use Microsoft Graph API v2.
