Application Control Licensing
As mentioned at the beginning of this section, for application control to function, the current
cOS Core license must allow it and a Clavister sales office can provide details about obtaining an
appropriate license.
Application control is a subscription service, so the expiry date for the feature may be different to
the expiry date of the license itself. Should the application control subscription expire, the
following will happen if application control has been configured on any IP Policy objects:
• A console message is generated at system startup or on reconfiguration to indicate
subscription expiry.
• Application control will continue to function so that traffic continues to flow through cOS
Core but, whenever it triggers, the data type will be set to Unknown.
For example, if the administrator had configured BitTorrent traffic to be dropped, it will no
longer be dropped because it has been recognized and then reclassified as Unknown traffic.
• Whenever application control triggers, the log message application_identified will be
generated as usual but the traffic type will be marked as Unknown. Similarly, the type
Unknown will also appear in the application_end log message.
• In addition, the log message application_control_disabled will also be generated when
application control triggers.
The current status of application control licensing can be viewed with the Web Interface by
going to Status > Maintenance > License.
