Editing Cisco PIX (section)

== Adaptive Security Appliance (ASA) ==
The '''Adaptive Security Appliance''' is a network [[firewall (computing)|firewall]] made by Cisco. It was introduced in 2005 to replace the Cisco PIX line.<ref>{{cite book|last1=Joseph|first1=Muniz|last2=McIntyre|first2=Gary|last3=AlFardan|first3=Nadhem|title=Security Operations Center: Building, Operating, and Maintaining your SOC|date=29 October 2015|publisher=Cisco Press|isbn=978-0134052014}}</ref> Along with stateful firewall functionality another focus of the ASA is Virtual Private Network (VPN) functionality. It also features intrusion prevention and [[Voice over IP]]. The ASA 5500 series was followed up by the 5500-X series. The 5500-X series focuses more on virtualization than it does on hardware acceleration security modules.

=== Software ===
The ASA continues using the PIX codebase but, when the ASA OS software transitioned from major version 7.X to 8.X, it moved from the Finesse/Pix OS [[operating system]] platform to the [[Linux]] operating system platform. It also integrates features of the Cisco IPS 4200 intrusion prevention system, and the Cisco VPN 3000 Concentrator.<ref>{{Cite web |url=http://www.ingrammicro.de/pdf/6778857.pdf |title=Archived copy |access-date=2016-02-11 |archive-date=2016-10-05 |archive-url=https://web.archive.org/web/20161005200533/http://www.ingrammicro.de/pdf/6778857.pdf |url-status=dead }}</ref>
