Overview & Background

This blog is focused on the Cisco ASA 5500 Series Security Appliance. I have been working with Cisco products since their routers had IOS 11.0. The intention of this blog is to share technical information, tutorials, tips and configuration examples in a simple "how to" manner.

The Cisco ASA is the descendant of the older Cisco PIX series firewall which became part of Cisco's portfolio when they acquired Network Translation in 1995. In 2005, Cisco introduced the ASA which combined functionality of the PIX, VPN Concentrator, and IPS Product lines. Through PIX OS release 7.x (codenamed finesse) the PIX and the ASA used the same software images. Beginning with PIX OS version 8.x, the operating system code diverges, with the ASA using a Linux kernel.

ASA Order of Operations

Several years ago I went to networkers in Las Vegas while there I attended an ASA seminar. In that seminar as a slide detailing the ASA "order of operations". This was darn handy and since you cannot get the slides anymore I recreated and improved upon it. This has become very helpful over the years to share with customers as well a priceless troubleshooting aid!

Enjoy!
