Collect Palo Alto Cortex XDR alerts logs

This document describes how you can collect Palo Alto Cortex XDR alerts logs by setting up a Google Security Operations feed.

For more information, see Data ingestion to Google Security Operations .

An ingestion label identifies the parser which normalizes raw log data to structured UDM format. The information in this document applies to the parser with the CORTEX_XDR ingestion label.

Configure Palo Alto Cortex XDR alerts

To configure Palo Alto Cortex XDR alerts, complete the following tasks:

• Get the Palo Alto Cortex XDR alerts API key .
• Get the Palo Alto Cortex XDR alerts API key ID .
• Get the fully qualified domain name (FQDN) .

Get the Palo Alto Cortex XDR alerts API key

1. Sign in to the Cortex XDR portal.
2. In the Settingsmenu, click Settings.
3. Select +New key.
4. In the Security levelsection, select Advanced.
5. In the Rolessection, select Viewer.
6. Click Generate.
7. Copy the API key, and then click Done. The API key represents your unique authorization key and is displayed only at the time of creation. It is required when you configure the Google Security Operations feed.

Get the Palo Alto Cortex XDR alerts API key ID

In the Configurationssection, navigate to API keys > ID. Note your corresponding ID number, which represents the x-xdr-auth-id:{key_id} token.

Get FQDN

1. Navigate to API keys.
2. Click Copy URL. Save the URL, which is required when you configure the Google Security Operations feed.

Set up feeds

To configure this log type, follow these steps:

1. Go to SIEM Settings > Feeds.
2. Click Add New Feed.
3. Select the Cortex XDRfeed pack.

4. Configure the following mandatory input parameters:

   • Source Type: Third party API (recommended)
   • Authentication HTTP headers: Provide the authorization key and authorization key ID that you obtained previously.
   • API hostname: Provide the URL that you obtained previously.
   • Endpoint: Specify the endpoint.

   Advanced options

   • Feed Name: A prepopulated value that identifies the feed.
   • Asset Namespace: Namespace associated with the feed.
   • Ingestion Labels: Labels applied to all events from this feed.

5. Click Create Feed.

For more information about configuring multiple feeds for different log types within this product family, see Configure feeds by product .

For more information about Google Security Operations feeds, see Google Security Operations feeds documentation . For information about requirements for each feed type, see Feed configuration by type .

Field mapping reference

This parser extracts security logs from Palo Alto Networks Cortex XDR in either JSON or SYSLOG (key-value) format, normalizes fields, and maps them to the UDM. It handles both JSON and key-value formats, performs date extraction, enriches the data with metadata, and structures the output for ingestion into Google SecOps.

Enable REST API requests on Cortex XDR and configure a Google SecOps feed

This guide provides step-by-step instructions for enabling REST API requests on Cortex XDR and configuring a corresponding feed in Google SecOps.

Part 1: Enable REST API requests on Cortex XDR

Cortex XDR uses API keys for authentication. Follow these steps to generate an API key:

1. Log in to the Cortex XDR management console.
2. Go to Settings.
3. Access API Keys.
4. Generate a new key.
5. Provide a key name (for example, "SecOps Integration").
6. Assign the API key the necessary permissions to access the required data. This is crucial for security and ensures the key only has access to what it needs. Consult the Cortex XDR documentation for the specific permissions required for your use case.
7. Securely store the API key. You will need it for the Google SecOps feed configuration. This is the only time you will see the full key, so make sure to copy it now.
8. (Optional) Configure an expiration date for the API key for enhanced security.

Part 2: Configure the feed in Google SecOps

After you generate the API key, configure the feed in Google SecOps to receive data from Cortex XDR:

1. Go to SIEM Settings > Feeds.
2. Click Add new.
3. Select Third Party APIas the Source type.
4. Select the required log type that corresponds to the data you want to ingest from Cortex XDR.
5. Click Next.
6. Configure the following input parameters:
   • API Endpoint: Enter the base URL for the Cortex XDR API. This can be found in the Cortex XDR API documentation.
   • API Key: Paste the API key that you generated earlier.
   • Other Parameters: Depending on the specific Cortex XDR API that you are using, you might need to provide additional parameters, such as specific data filters or time ranges. Refer to the Cortex XDR API documentation for details.
7. Click Nextand then click Submit.

Important considerations:

• Rate limiting: Be aware of any rate limits imposed by the Cortex XDR API. Configure the feed accordingly to avoid exceeding these limits.
• Error handling: Implement proper error handling in your Google SecOps configuration to manage situations where the Cortex XDR API is unavailable or returns errors.
• Security: Securely store the API key and follow security best practices. Regularly rotate API keys to minimize the impact of potential compromises.
• Documentation: Refer to the official Cortex XDR API documentation for detailed information on available endpoints, parameters, and data formats.
