Hence, hardware firewalls have an edge over software-based firewalls.
The Cisco Firewall technology provides a wealth of advanced security and networking services for small-tomedium
enterprise and service provider networks, in a modular, purpose-built solution. Cisco hardware-based
firewall technology comes in three flavors:
PIX 500 Series Security Appliances
ASA 5500 Series Adaptive Security Appliances
Catalyst 6500 Series and Cisco 7600 Series Firewall Services Module (FWSM)
Cisco Firewall technology solutions provide application-aware and protocol inspection, access control and flowbased
policy enforcement, multi-vector attack protection, and secure connectivity services through a wide range
of rich security and networking services. The following sections will briefly highlight features of each platform.
