Intrusion Detection recommendations

The PIX was originally developed as a “Network Translation, Inc.” box (translation.com <http://translation.com/>). (John Mayes, Brantley Coile, Johnson Wu)

Cisco continued the PIX name for many years and through some major changes to the operating system. A later round of major changes had it renamed to ASA.

Up through PIX 7 the PIX and ASA ran the same code releases. With PIX 8, PIX continued on the Finesse OS line, but ASA went to a Linux kernel.
