These are a manual process. Tools may aid in the process, but it is
still a process of comparing config to policy (and hopefully one
exists).
No tool can decide what is good for a firm/company. Tools will help
extract the data, but to my knowledge there is no expert system that
will analyse a company security policy and map it to a list of ingress
and egress filters. (Maybe a good topic for a hopeful PhD candidate in
Computational Linguistics, Computational learning and Security).

I would say that the best audit for firewalls are manual. There are
tools that can point things out to you, but usually I run nessus or
similar from the outside to gain knowledge of open ports, then I
manually go through the acl's. Once, that's cleaned up, look at your
object groups, hit counters, and translations.

Subject: Re: Firewall rulebase audit
Hi
You can check check this:
CIS Level 1 & 2 Benchmarks and Audit Tool for Cisco IOS Routers and PIX
firewalls.
http://cisecurity.org/bench_cisco.html
I have a pair of PIX firewalls that I need to audit. I was hoping to
get some guidelines for doing this. Antyhing specific to PIX would be
even better.
1) What is the best/easiest way to document a current policy?
Spreadsheet?? I would like to know what ports (services) are open and
to where? Also duplicates, etc.? Would it be best just to put it in a
spreadsheet? Is there a tool for this?
2)Is there standard Analysis checklist to go by when reviewing a (PIX)
firewall policy?
Any help is highly appreciated.
Thank you,
