Re: Application Intelligent vs ALG

[Frederick M Avolio <fred () avolio com>]

A fancy proxy.

Three different people from Check Point wrote me in response to a recent 
column of mine, basically asking me if I had heard of this new feature.

I replied with a brief history. In short: Firewall-1 comes on the scene, 
most FW1 users implement it with modules from the TIS FWTK (for adding user 
authentication to FTP and TELNET), Check Point's marketing says proxies are 
old technology, stateful inspection is the next generation of firewall 
technology (before the term became a product name), people persisted in 
using proxies, CP added "security servers" (proxies by another name), and 
now this.

I asked them, how is this different from application gateways (security 
proxies). I applaud the addition of them (like there are other hybrid 
firewalls). But none of the three folks from CP replied to me.

I have no agenda, except the truth. (Boy, is this guy noble, or what? :-)) 
I'd like to know the answer to this: How this is different than application 
gateways (if it is), and why is it better than Sidewinder, Firebox, Raptor, 
et al.
