User Defined Application Control Code?

[HeikoAnkenbrand]

Is it possible to create user defined code for the application control blade?

I would like to build a rule for my own application created by a customer, which blocks this application to the internet.

For example, the following string is included in the html code "app-tuning-db". Now I would like to create a user defined application, which recognizes exactly this string in html stream. If my own application is recognized, it should be blocked by the application control blade in the direction of the internet.

Now my question:

Can I create user defined applicationons?

If so, where can I find informations?

Important!
I will not use the DLP blade!

The only thing that comes to my mind is the  Signature Tool for custom Applications (Admin Guide) together with the R80 import function.

Hi @Danny,

Thanks, that is exactly what I was looking for!

I used this to create a custom signature that would display a UserCheck interaction to outdated Chrome, IE, Firefox & Safari browsers.  It would present them with a notice that their browser was out of date & missing critical security updates.  The UserCheck also included links to download & install the latest version of their browser.  It worked liked a charm!  Good luck!

How about creating a snort rule and let IPS block the communication ?
