Endpoint Protection Blocks Backup Exec Agent on some IPs

Hi all, I am receiving the following security alert from Symantec Endpoint Protection on my Backup Exec 2010 R3 server:

[SID: 25721]Web Attack: RTMP Type Confusion CVE-2012-0779 2 detected.

Traffic has been blocked from this application: C:\Program Files\Symantec

\Backup Exec\bengine.exe

I have received this for a few of my backedup machines and was wondering what the best practice is to stop this from happening.

I would assume the way is to create an application rule for "bengine.exe" in the Symantec Endpoint Protection Manager (SEPM) firewall policy as out lined in this article? http://www.symantec.com/docs/TECH104526 Is this correct? Or is there a different/better way?

Thank you in advance

Mike
