Thank you,

Subject: RE: firewall change request


There have been a couple really good, detailed answers to this issue. Do
others on the list have no change controls to speak of? And if you do,
what changes are people allowed to make without a requiring a formal
process of review, approval and documentation? For those with clear
policy guidance, would you be willing to share the details?

For me, our policy says that the change request process is required for
"any change that has a reasonable expectation of impacting customer
service availability". In reality though, we go through the full process
for any and all firewall rule changes, regardless the expected impact on
service availability, like adding a host object to a group, then
installing policy. 

We use a browser-based form in which we specify the changes to be made
and their impact. This must receive the prior approval of at least one
of seven IT supervisors, and at least one higher level IT manager. One
of these supervises the firewall team, the other has authority over IT
for a business unit that might be affected. Neither has more than
rudimentary experience in or knowledge of firewalls or networking. The
other five can sign off the change after the fact.

(In reality, we first request permission to submit the request, from
these same supervisors. The form doesn't get filled out until we've
received their permission do it. We request permission to request
permission to perform a change. The entire process can take up to a
week.)

They then specify when the change can be made. Some changes are made the
same day during business hours, others wait until an after hours window
opens, usually simply after 5:30 pm. In the case of one critical
firewall cluster, there is only one window per month, a Tuesday between
4:00 am and 6:00 am.
