Is there a way to force Spark to use Wildfire as a proxy for file transfers? We are trying to prevent users from transfering files outside of the company’'s firewall by blocking port 7777 but all file transfers are using the XMPP port (5222) instead…
Is there a way to disable all Spark file transfers then? If not is there a way to do the same by setting firewall rules? Do the file transfer packets have anything specific in them?
Finally, how hard would it be to modify Spark to disable file transfers or force it to use a proxy?
If you control the client, in this case Spark, yes you can modify it to remove the file transfer functionality. Also, the disabling of file transfers comes as part of WIldfire enterprise.
