Barracuda CloudGen Firewall

CC FWAUDIT Tab

  • Last updated on

The FWAUDIT tab provides access to the Firewall Audit viewer. The Firewall Audit viewer displays information related to firewall sessions on managed F-Series Firewalls. The type of data collected depends on the FW Audit settings on the individual units. For more information, see FW Audit. Similar to the Log Viewer directly on the firewall, the Firewall Audit viewer supports navigating to a dedicated date/time and browsing backward and forward.

Log File Display Modes

The FWAUDIT page lists firewall audit data information according to the specified filter selection and time interval. By default, all entries are shown line by line in the list (Log File Mode). The Log File Mode drop-down list provides two display options:

  • Log File Mode – Log files are shown line by line according to the specified filter selection and time interval.
  • Accumulation Mode – Log files are shown accumulated by specified merging criteria. This provides a more general overview of similar event or session categories.
Log File Mode

By default, all entries are shown line by line in the list (Log File Mode). In the navigation bar on the top right of the ribbon bar, you can select how information is displayed in the list. Use the Max Entries field to adjust the number of entries displayed in the list. To view a log entry, double-click it.
