If No – Synchronization performed using ntp.barracudacentral.com, regardless of whether you specified other NTP servers.
Specifying Web Interface Settings

Web Interface Certificate – Select either the Default certificate or a user-defined certificate.
If you select a user-defined certificate, you can choose between:

Minimum value: 1 minute. Default setting: 20 minutes.
Update Dashboard Every 30 Minutes – Select Yes to automatically refresh the dashboard so you can see the most recent information.
If you select Yes, as long as you leave the dashboard up as the active screen, you will not be logged out of the dashboard, and it will continue to display updated information every 30 minutes. When you switch to a different tab, if the Session Expiration Length has passed, you will be logged out.
If you select No, the Session Expiration Length will apply to the Dashboard along with the rest of the tabs.
Viewing Connected Devices
Use the Connected Devices section to specify the shared secret for devices you want to connect, to view devices that are connected to Barracuda Firewall Insights, and to specify their log retention period.
As part of your configuration process, you set up Barracuda devices to point to Barracuda Firewall Insights. If they connect correctly, the device connections will appear in this section. See Getting Started for information on how to connect devices.
Log Retention Period – Specify how long you want to retain logs for all connected devices: 1 month, 2 months, 3 months, 6 months, 9 months, or 12 months. One month is defined as 31 days.
- The Kafka Log Retention period relates to how long the log files received from a firewall are stored on Firewall Insights. For more information, see Understanding Data Retention and Storage Capacity.
Shared Secret – Enter the Shared Secret you will use for each device for which you want to collect reports. On every device you want to connect, enter this same shared secret.
The Connected Devices table provides the following information:
Device – To have a unique name, the device name consists of hostname + domain name for the connected device.
- Serial – The unique identifier for each device.
IP Address – The address of the connected device.
