FortiView sources

TheFortiView Sourcesmonitor displays top sources sorted by Bytes, Sessions or Threat Score. The information can be displayed in real time or historical views. You can use the monitor to create or edit a firewall device address or IP address definitions, quarantine hosts, and temporarily or permanently ban IPs.

To add a firewall device or IP address:

2. ClickFirewall Address > Create Firewall Device AddressorFirewall Address > Create Firewall IP Address. The New Addresspane opens.

3. Configure the address settings as needed, then clickOK.

Use theNamefield to assign a descriptive name to a device so it is easier to find it in the Devicecolumn. After you finish configuring the device, refresh the page to see the new name in the monitor.

1. In the table, hover over the source or device MAC address. An information window opens.

2. ClickQuarantine > Quarantine Host. TheQuarantine Hostdialog is displayed.

FortiView Sessions

TheFortiView Sessionsmonitor displaysTop Sessionsby traffic source and can be used to end sessions.

To view theFortiView Sessionsdashboard, go toDashboard > FortiView Sessions.

The session table displayed on theFortiView Sessionsmonitor is useful when verifying open connections. For example, if you have a web browser open to browse the Fortinet website, you would expect a session entry from your computer on port 80 to the IP address for the Fortinet website. You can also use a session table to investigate why there are too many sessions for FortiOS to process.

You can filter the sessions displayed in the session table by setting up the available filtering options.

To filter sessions in the session table:

1. Click on theAdd Filterbutton at the top of the session table.

2. Select the required filtering option. The session table updates to the filter selection.

3. You may add one or more filters depending upon your requirements. To add more filters, repeat the above steps for a different set of filters.

You can be very specific with how you use filters and target sessions based on different filter combinations. For example, you may want to view all sessions from a device with a particular IP by adding theSource IPfilter. Similarly, you may need to target all the sessions having a particularDestination IPandDestination Port, and so on.

You may also view the session data in the CLI.

To view session data using the CLI:

# diagnose sys session list

The session table output in the CLI is very large. You can use the supported filters in the CLI to show only the data you need.

To view session data with filters using the CLI:

# diagnose sys session filter <option>

See to learn more about using the supported filters in the CLI.

You may also decide to end a particular session or all sessions for administrative purposes.

To end sessions from the GUI:

1. Select the session you want to end. To select multiple sessions, hold theCtrlorShiftkey on your keyboard while clicking the sessions.

2. Click onEnd Session(s)to end the selected sessions, orEnd All Sessionsto end all active sessions.

3. ClickOKin the confirmation dialog.
