Configuring ArcSight CEF formatted Syslog events on your Palo Alto PA Series Networks Firewall device

Configure your Palo Alto Networks firewall to send ArcSight CEF formatted Syslog events to IBM® QRadar®.

1. Log in to the Palo Alto Networks interface.
2. Click the Device tab.
3. Select Server Profiles > Syslog.
4. Click Add.
5. Specify the name, server IP address, port, and facility of the QRadar system that you want to use as a Syslog server:
   1. The Name is the Syslog server name.
   2. The Syslog Server is the IP address for the Syslog server.
   3. The Transport default is UDP.
   4. The Port default is 514.
   5. The Faculty default is LOG_USER.
6. To select any of the listed log types that define a custom format, based on the ArcSight CEF for that log type, complete the following steps:
   1. Click the Custom Log Format tab and select any of the listed log types to define a custom format based on the ArcSight CEF for that log type. The listed log types are Config, System, Threat, Traffic, and HIP Match.
   2. Click OK twice to save your entries, then click Commit.
7. To define your own CEF-style formats that use the event mapping table that is provided in the ArcSight document, Implementing ArcSight CEF, you can use the following information about defining CEF style formats:
   1. The Custom Log Format tab supports escaping any characters that are defined in the CEF as special characters. For example, to use a backslash to escape the backslash and equal characters, enable the Escaping check box, specify \= as the Escaped Characters and \ as the Escape Character.
   2. The following list displays the CEF-style format that was used during the certification process for each log type. These custom formats include all of the fields, in a similar order, that the default format of the Syslogs display.
      Important: Due to PDF formatting, do not copy and paste the message formats directly into the PAN-OS web interface. Instead, paste into a text editor, remove any carriage return or line feed characters, and then copy and paste into the web interface.
