The ASA 5585-X has a slot for an I/O module. These range in processing power by a factor of 10, from SSP-10 SSP-20, SSP-40 and SSP-60. SSP stands for security services processor. The configuration is initially in memory as a running-config but would normally be saved to flash memory.OptionsThe 5512-X, 5515-X, 5525-X, 5545-X and 5555-X can have an extra interface card addedThe 5585-X has options for SSP. In config mode the configuration statements are entered. There is a command line interface (CLI) that can be used to query operate or configure the device. 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.The ASA software has a similar interface to the Cisco IOS software on routers. The ROMMON also has a command line that can be used to load or select other software images and configurations. In the boot sequence a boot loader called ROMMON (ROM monitor) starts, loads a Linux kernel, which then loads the lina_monitor, which then loads lina. This schedules processes internally rather than using the Linux facilities.
It runs a single Executable and Linkable Format program called lina. It's typically placed in the forwarding path so that all packets have to be checked by the firewall, where we can drop or permit them.ArchitectureThe ASA software is based on Linux.
