Explanation/Reference:
The Cisco advances in firewall technologies include the acquisition of the original Private
Internet Exchange (PIX) technology in 1995. Today Cisco continues to develop PIX
capabilities. The Cisco PIX appliances represent network layer firewalls that employ
stateful inspection. These firewalls allow internal connections out (outbound traffic) and
only allow inbound traffic that is a response to a valid request or that is explicitly allowed
by an access control list (ACL). Cisco PIX technology may be configured to perform a
variety of critical network functions, including Network Address Translation (NAT) and
Port Address Translation (PAT).
In addition to working with Cisco PIX appliances, you may choose to use the features of
the Cisco IOS Firewall embedded in Cisco IOS software. This allows you to turn your
router into an effective, robust firewall with many of the capabilities of the Cisco PIX
Security Appliance.
Cisco offers the Adaptive Security Appliance (ASA), which provides an easy-to-deploy
solution that integrates firewall, Unified Communications (voice/video) security, SSL and
IPsec VPN, intrusion prevention system (IPS), and content security services.
