A hardware firewall will typically run off an ASIC chip and will not have a hard disk. Examples of a hardware firewall would be Netscreen. Watchguard however is a hybrid firewall. It uses a combination of an ASIC chip and software.
An appliance firewall is defined as a firewall that comes with an appliance. These appliances are often "pc's in a box" that have a hard disk, cpu ram etc. A example of an appliance firewall is the Cyberguard. These firewalls often provide the option of RAID to reduce the chances of a single hard disk failure. ----- Original Message ----- From: "Stadler, Brian T" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, March 20, 2003 1:46 AM Subject: RE: Cisco Pix Vs.
