RE: Firewall vs. IPS - Differences now (ISS, Intrushield 2.1?)

["Brito, Nelson (ISS Brazil)" <NBrito () iss net>]

The confusion is: there three series of Proventía Appliances.

1 - Proventía A (A201, A604, A1204 and A1204F): IDS Appliances;
2 - Proventía G (G100, G200, G1000, G1200 and G1200): The IPS Appliances;
3 - Proventía M (M10, M30 and M50): Integrated Security Appliances, which is mainly a Firewall.

It does not mean that you cannot use the Proventía G Series as a static address filter, because if you can do it 
dynamically (one of the three methods used by Porventía G) you, of course, can do it statically.

Take a look at:

Things are getting a little confusing. ISS claims that its Proventia boxes are also firewallas. Intrushield 2.1 has 
firewall/layer 4 filtering capabilities now. If the Intrushield box layer 4 acls now then what makes it not be equal to 
a firewall? What does a firewall do that an IPS doesn't as long as the IPS can do layer-4 access lists? Any info is 
apprecaited.
