This section describes the
Expiration
feature. With the
Expiration
feature, virtual applications
can be set to expire after a certain number of days or after a certain date.
To set a virtual application to expire after a specific number of days:
•
Click on the
Expiration
button.
•
Check the
Disallow execution after number of days
checkbox.
•
Select the number of days after the application is first executed on a system it will take to
expire.
•
Choose the
Time Source
the virtual application will use to validate the date.
To set a virtual application to expire after a certain date:
•
Click on the
Expiration
button.
•
Check the
Disallow
execution after date checkbox.
•
Select the date the virtual application will expire.
•
Choose the
Time Source
the virtual application will use to validate the date.
For all expiration modes, the
System clock
setting will use the host system's clock to validate the
date. The
Web server clock
setting will validate the date against an HTTPS-based web
server. Check the
Disallow execution if web server is unreachable
checkbox to prevent the
application from being executed offline.
Tip: The
Web server clock
setting is more secure than the
System clock
setting since it prevents
the expiration mechanism from being circumvented by modifying the system clock. However, this
setting will prevent applications from executing on devices which cannot connect to the time
server source.
Optionally, an
Expiration Warning
can be set to warn the user when the virtual application is
about to expire. The message will be displayed each time the virtual application is executed when
it is within the specified threshold.
