Cisco ASA Software
Q. What is Cisco
®
Adaptive Security Appliance (ASA) Software?
A. Cisco ASA Software is the core operating system that powers Cisco ASA firewall products. It offers stateful
firewalling, VPN capabilities, and clustering capabilities; provides for the scalability of ASA hardware; and
integrates with other security solutions like Cisco IPS, Cisco Cloud Web Security, Cisco Identity Services
Engine (ISE), and Cisco TrustSec
®
technology. In addition, it offers next-generation firewall capabilities
through the ASA CX software module on ASA5500-X or through a Security Services Processor (SSP) in the
ASA 5585-X appliances.
Q. What operating system is the ASA built on?
A. Cisco ASA Software runs on Linux as an ASA OS process. Cisco ASA Software is not forked off Cisco IOS®
Software. Its roots are in the Cisco Finesse

OS (an embedded OS), which ran on older Cisco PIX® firewall
platforms.
