The Cisco ASA Series provides intelligent threat defense that stops attacks before they penetrate the network perimeter, controls network and application activity, and delivers secure remote access and site-to-site connectivity. The result is a powerful multifunction network security appliance family that provides security breadth, precision, and depth for protecting business networks of all sizes, while reducing the overall deployment and operations costs associated with implementing comprehensive multilayer security. The Cisco ASA Series helps businesses increase effectiveness and efficiency in protecting their networks and applications, while delivering exceptional investment protection through the following elements:. These technologies deliver strong network- and application-layer security, user-based access control, worm mitigation, malware protection, improved employee productivity, instant messaging and peer-to-peer control, and secure remote user and site connectivity. The innovative extensible multiprocessor design and software architecture of the Cisco ASA Series enables businesses to easily install additional high-performance security services through security services modules SSMs and security services cards SSCs. This provides businesses with outstanding investment protection, while enabling them to expand the security services profile of their Cisco ASA Series, as their security and performance needs grow.

The Cisco ASA is a unified threat management device, combining several network security functions in one box. The ASA software is based on Linux. It runs a single Executable and Linkable Format program called lina.
This schedules processes internally rather than using the Linux facilities. The names of firmware files includes a version indicator, -smp means it is for a symmetrical multiprocessor and 64 bit architecture , and different parts also indicate if 3DES or AES is supported or not. There is a command line interface CLI that can be used to query operate or configure the device.
In config mode the configuration statements are entered. The configuration is initially in memory as a running-config but would normally be saved to flash memory. The X has options for SSP. SSP stands for security services processor. This slot can be subdivided into two half width modules. On the low end models, some features are limited, and uncrippling happens with installation of a Security Plus License. The introduced in was a desktop unit designed for small enterprises or branch offices.
It included features to reduce the need for other equipment, such as an inbuilt switch, and power over Ethernet ports. Cisco determined that most of the low end devices had too little capacity to include the features needed, such as anti-virus, or sandboxing, and so introduced a new line called next generation firewall.
