Some years ago my Web Operations team was given the responsibility by the Network team for making sure that all firewall rules relating to our service were correct, secure and up to date.Great! We thought, we can totally use this as a chance to optimise, align and really take control of this important area of our service.But there was a catch!We were not allowed access to firewall to view the current rules directly. If we wanted to see the rules then we needed to raise a ticket and our rules would be exported to a spreadsheet (sometime within 1-3 days) and we CERTAINLY would never be allowed to modify and publish our rules directly.Instead we needed to raise a ticket describing the changes we wanted and someone would interpret those instructions (usually incorrectly), implement them for us (because hey, we couldn't possibly learn and understand how to do something so specialised and complex ourselves!) and then ask us to check the result (which remember requires another ticket to get the latest view of the rules!)
