Intrusion Detection recommendations

I believe the ASA was first developed as the PIX on Plan 9.  The OS that came out of that was originally called Finesse OS, but was later renamed as PIX OS.  After Cisco purchased the PIX and renamed it to the ASA, they began using a Linux kernel around PIX OS V8.

The ASA, like so many network/security appliances anymore, runs Linux (or
*BSD) under the hood, however I don't know how old or horribly mangled it is.
