Barracuda WAF Integration
To configure Barracuda WAF to send log data to the USM Anywhere Sensor
- Go to the ADVANCED > Export Logs page.
- In the Export Logs section, click Add Export Log Server.
In the Add Export Log Server window, specify values for the following
- Name — a name for the export log server
- Log Server Type — the server type to export the logs
- IP Address — the IP address of the export log server
- Port — the port associated with the IP address of the export log server
- Log Timestamp and Hostname — to log the date and time of the event and the hostname (configured in BASIC > IP Configuration > Domain Configuration), set this to Yes
To configure facilities for different log types
- Go to ADVANCED > Export Logs.
- In Export Logs, select Export Log Settings.
In the Syslog Settings section of the Export Log Settings dialog box, select the appropriate facility (Local0 to Local7) from the list for each log type, and click Save.
Note: You can set the same facility for all log types. For example, you can set Local0 for System Logs, Web Firewall Logs, Access Logs, Audit Logs, and Network Firewall Logs.
In the Export Log Settings dialog box, you can
- enable or disable the logs that needs to be exported to the configured export log server(s) in Export Log Settings
set the severity level to export web firewall logs and system logs to the configured export log server(s) In Export Log Filters

The Barracuda Web Filter plugin automatically processes all messages whose syslog tag matches one of the following values:
