Cisco ASA
From Wikipedia, the free encyclopedia
In computer networking, Cisco Adaptive Security Appliance 5500 Series, or simply Cisco ASA, is Cisco's line of network security devices introduced in 2005,[1] that succeeded three existing lines of popular Cisco products:
- ASA succeeded Cisco PIX, which provided firewall and network address translation (NAT) functions.
- ASA succeeded Cisco IDP 4200, which worked as intrusion prevention system (IPS).
- ASA succeeded Cisco VPN 3000 Series Concentrators, which provided virtual private networking (VPN).

[edit] Specifications of past and present models
Like the Cisco PIX firewalls, the ASAs are based on Intel x86 architecture. The ASA series of devices run PIX code 7.0 and later. Through PIX OS release 7.x the PIX and the ASA use the same software images.
Beginning with version PIX OS version 8.x, the codes diverge, with the ASA using a Linux kernel and PIX continuing to use the traditional Finesse/PIX OS combination.[2]
