Sourcefire VRT Certified Rules Update

Synopsis:
This release provides two new rule groupings, Voice over IP (VoIP) rules and 
Content-Replace rules.

Details:
Voice over IP rules:
This group contains rules that are concerned with Voice over IP (VoIP) 
detection. This rule group focuses on known exploit attempts as well as 
providing detection for anomalous events.

Content-Replace rules:
This group contains rules that concentrate on replacing transaction data with 
innocuous strings to effectively deny a valid transaction while keeping a 
connection active. This allows a deployment where instant messaging may be 
allowed for communication purposes but where file transfer is prohibited.

For a complete list of new and modified rules please see:
