+# CyberArk Privileged Threat Analytics
+
+<~XSIAM>
+
+This pack includes Cortex XSIAM content.
+
+This pack contains a beta Modeling Rule, which lets you process CyberArk PTA log fields to XDM fields.
+Since the Modeling Rule is considered as beta, it might not contain some of the fields that are available from the logs.
+We appreciate your feedback on the quality and usability of the Modeling Rule to help us identify issues, fix them, and continually improve. 
+
+## Configuration on Server Side
+You need to configure CyberArk Privileged Threat Analytics (PTA) to forward Syslog messages in CEF format.
+
+Access your Cyberark PTA machine and follow these instructions [Product Documentation](https://docs.cyberark.com/PAS/Latest/en/Content/PTA/Outbound-Sending-%20PTA-syslog-Records-to-SIEM.htm):
+1. On the PTA machine, open the default **systemparm.properties** file using the ***DEFAULTPARM*** command.
+2. Copy the line containing the **syslog_outbound** property, and exit the file.
+3. Open the local **systemparm.properties** file using the ***LOCALPARM*** command.
+4. Press **i** to edit the file.
+5. Paste the line you copied, uncomment the **syslog_outbound** property and edit the parameters. Use the following as a guide.
+   * format - CEF.
+   * protocol - UDP.
+   * siem - Assign a name to your configuration.
+   * host - Write the dedicated hostname or IP address.
+   * port - Write the dedicated port number.
+   * syslogType - RFC5424.
+
+## Collect Events from Vendor
+In order to use the collector, use the [Broker VM](#broker-vm) option.
+
+### Broker VM
+To create or configure the Broker VM, use the information described [here](https://docs-cortex.paloaltonetworks.com/r/Cortex-XDR/Cortex-XDR-Pro-Administrator-Guide/Configure-the-Broker-VM).
+
+You can configure the specific vendor and product for this instance.
+
+1. Navigate to **Settings** &rarr; **Configuration** &rarr; **Data Broker** &rarr; **Broker VMs**.
+2. Go to the **Apps** column under the **Brokers** tab and add the **Syslog Collector** app for the relevant broker instance. If the app already exists, hover over it and click **Configure**.
+3. Click **Add New** for adding a new syslog data source.
+4. When configuring the new syslog data source, set the following values:
+   | Parameter     | Value   
+   | :---          | :---        
+   | `Vendor`      | Enter **cyberark**.
+   | `Product`     | Enter **pta**.
