Instructions for configuring log collection for the Sumo Logic App for PCI Compliance for Palo Alto Networks.

This page has instructions for collecting logs for the PCI Compliance for Palo Alto Networks app.

Log Types

Parsing in the PCI Compliance for Palo Alto Networks app is based on the PAN-OS Syslog integration, which is described in this document: PAN-OS Syslog Integration. 

Prerequisites/requirements

  • Configure Syslog Monitoring for your Palo Alto Networks device, as described in Configure Syslog Monitoring in Palo Alto Networks help.
  • This app supports Palo Alto Networks v7 and v8.
  • Parsing in the PCI Compliance for Palo Alto Networks is based on the information described in Traffic Log Fields. 

Configure a collector and source

In this step you configure a installed collector with a Syslog source that will act as Syslog server to receive logs and events from Palo Alto Networks devices.

  1. Configure an Installed Collector
  2. Add a Syslog source to the installed collector:
    1. Name. (Required) A name is required.
    2. Description. Optional.
    3. Protocol. UDP or TCP.  Choose the protocol you configured in Palo Alto Networks for Syslog monitoring.
    4. Port. Port number. Choose the port you configured in Palo Alto Networks for Syslog monitoring.
    5. Source Category. (Required) The Source Category metadata field is a fundamental building block to organize and label Sources. For details see Best Practices.
    6. Click Save.
