Do we need another firewall for all new services? There are several Media specialized firewalls, often called Session Border Controller that does this, but is this the way to do it? Probably not. IMHO it is to have a good security audit and overview of your own infrastructure, take control! Don’t buy yourself out of the current biggest threats, there will be new! Take control with IDS and even IPS, and have backup plans in case serious bugs and flaws makes your services vulnerable!

And good there is several other people talking about security, like Mark Collier and the folks behind the bluebox security podcast! Good job!
