The Certificates screen displays data about all detected SSL certificates participating in
traffic that is captured by the Network Sensors. A certificate is identified by the server
name on which it resides, the port number, and a common name. For each certificate,
its validity dates and last update date are displayed.
Certificates that have expired are displayed with a red background, certificates that
are about to expire are displayed with a yellow background.
When a certificate is about to expire or has expired, a notification is generated and
displayed in the Notifications screen. The notifications can be configured to generate
email messages or SNMP traps.
Additionally, an event is opened for the server on which this certificate is installed. The
server is displayed with a background color matching the event severity, and so are the
application maps that include this server. It is possible to close the event from the
The properties window of the server, or in the Notifications screen.
Note: In order to identify certificates, full capture of traffic is required. I.e. this
data is not available when using NetFlow.
Select certificates that should be hidden from the list. It is possible to show these
certificates again by selecting them through the ‘Show hidden certificates’ dialog.
Select certificates to remove from the list. Note that these certificates may appear
again if they used again and observed in the captured traffic. Deleting certificates does
not hide them from now on, only removes the current observation results.
