Manage Applications that Use Multiple Protocols

Many applications today, especially instant messaging and peer-to-peer applications, use multiple protocols and techniques to transfer files. For example, there are many clients that use the BitTorrent protocol and other protocols to transfer files. To fully block applications that use multiple protocols, you must configure Application Control with a combination of actions. This is best illustrated as an example.

For example, when you select the BitTorrent Series application in an Application Control action, Application Control uses a set of rules that identify the BitTorrent protocol for peer-to-peer file sharing. Many different applications use BitTorrent as a method to download files. It is important to understand that if you configure Application Control to block BitTorrent Series, Application Control blocks BitTorrent use by all applications. There is no way to block BitTorrent use by one application, but allow it for other applications.

Example: Block FlashGet

When you select the BitTorrent Series application in an Application Control action, Application Control uses a set of rules that identify the BitTorrent protocol for peer-to-peer file sharing.

FlashGet is a client application that is used for file sharing. The FlashGet client application can use the BitTorrent peer-to-peer protocol to download files, or it can use simple HTTP downloads, FTP file transfer, or the proprietary FlashGet protocol.

If you do not block, but only record activity in the log files, BitTorrent downloads that are triggered by the FlashGet client appear in the log files and reports as both FlashGet and BitTorrent application activity, at different times.

To block all possible file transfers by the FlashGet client, you must configure Application Control to block FlashGet, and also to block BitTorrent Series, Web File Transfer, and FTP Applications. It is important to understand that if you block BitTorrent Series, Application Control also blocks BitTorrent use by all other applications. There is no way to block BitTorrent use by FlashGet, but allow it for other applications.

If you block FlashGet, but do not block BitTorrent or Web File Transfer, downloads through BitTorrent or HTTP are not blocked, even if the downloads are started by the FlashGet client.

If you block Web File Transfer or FTP Applications, this functionality is blocked for all applications. There is no way to block HTTP file transfers or FTP file transfers for FlashGet but allow it for other applications.

To fully block all file transfers through applications that use multiple protocols and applications, you must block the application, and you must block all protocols and applications the application uses. There are some common applications and protocols that you may not want to block because they are used by many applications.

For a description of any of the applications or protocols in this table, you can look up the application on the WatchGuard Application Control Security Portal at http://www.watchguard.com/SecurityPortal/AppDB.aspx.
