Could you point to guidelines regarding security issues with opening up UDP ports in a corp. firewall to allow UDP video streaming from the Internet?
We all know UDP to be superior to http tunnels for video. But firewalls block UDP by default. What would be a good, crips answer explaining why allowing UDP streaming would not represent a serious security risk?
Most of the multimedia applications use UDP dynamically opening different ports. Without the application support on the firewall, you may end up opening up the entire range of UDP ports which is a security threat. As PIX supports H323 video streaming by way of enabling the UDP ports dynamically, the ASA intellligently avoids any vulnerability.
