How would i go about filtering out the file upload and download functionality in messenger ?
I've already disallowed the possibility of uploading or saving from Messenger by not allowing the program the read or write files. But when a PC without this policy on it uploads to a CSA protected host. The CSA will download the entire file but then refuse to save the file.
I'd rather disallow this functionality alltogether ? my guess are that i would hae to do some COM filtering ?
I'd be greatfull for any hints you might have.
Best Regards,
Lasse

The document Blocking Peer-to-Peer File Sharing Programs with the PIX Firewall has more information on blocking file sharing applications.
