manage your network, and Realtime Monitor to monitor the up/down connection status
of all your security devices.
One day, you notice that the Connection Status on a mission-critical security device
indicates that the security device is DOWN. You wait several minutes to see whether the
connection status resolves itself because intermittent network problems might cause a
security device to temporarily indicate as DOWN. The Device Monitor still indicates that
the security device is DOWN.
You next try to ping the security device. If you are successful in reaching the device, you
can send a get status command to check the status of the security device.
If you cannot ping the security device, you need to investigate further. You scan the Log
Viewer for the log entry indicating that the security device has disconnected. You can
filter the log entries in the Log Viewer to display only the log entries generated for the
security device during the time just before it went down. Viewing these log entries will
also provide you with context for events leading to the security device disconnection.
This will help you to determine the cause of the problem.
You notice several very suspicious log entries that indicate that this security device may
have been the target of an attack. You flag the log entries using the predefined flag types
in the Log Viewer, and assign them to your security experts for further investigation.
