Re: Firewall Rule Audit Software/Service

We are in the process of a major revamp of our rules. We recently changed
vendors so some old rules no longer "fit" with the new firewall. We have
recently started using spreadsheets for tracking.

We have two SOPs for firewall changes. One is used for internal requests
for internal communications from our ERP, Server and Network teams. They
enter the applicable info into the spreadsheet and notify the security team
a change has been requested. This covers 90% of our requests. For internal
communications requests from non-IT personnel or any request for
external/Internet based clients to communicate to internal resources, we
use a form that requires approval from department heads.  We are a two man
security team with automatic notifications of changes generated by our
firewalls sent to both security team members for review and confirmation.
This works for us but can be improved. We have a change management process,
but, firewall changes that are minor are considered routine and do not
require review. Major changes and code updates go through the change
procedure.

Roman, we have something similar... RANCID checks our configs hourly, and
emails the entire itsec team of any changes

A formal change control policy/process is the best security control for
managing authorized administrator changes. I also have a script that runs
daily and notifies me of any changes to the firewall config, this can
easily be modified to notify the entire team whenever any configuration
item is changed.

Do you have a formal process that must be followed for an exception to be
made?  Our problem is that several people have legitimate access to make
updates—but getting everyone to follow the same process is a challenge.

mine.

I’d love to hear the answer to this one.  Even just learning how people
tackle documenting and reviewing their rules would be beneficial.

We are looking at updating our Firewall Rule Audit structure so that we
check over all of our rules at least once a year to verify whether they
still need to be in place. Since we have multiple groups & multiple
firewalls, each with their own specific set of rules the goal is to have
some central structure where the audit can be recorded. Are any of you
using a software or service that provides the ability for multiple users to
log in & check off firewall rules? Please feel free to contact me off list
if that is better for you.



Thank You,

Will Telfer, M.S.
