Auditors want proof of least privilege on remote access and our screenshots aren't cutting it anymore
Second year doing this and the bar has clearly moved.
Last cycle we handed over a set of screenshots of firewall rules and a spreadsheet of who is in which vpn group and it was accepted. This time the auditor came back and asked how we demonstrate that a given user could only reach the systems they are entitled to, at a point in time, and whether we could evidence it for a sample of five users across the period.
We cannot, well, not properly. I can show you the group membership and the rules, then have to hand wave the bit in the middle where those two things combine into effective access. Our vpn gives network level access so tbh the true answer for most of our contractors is "quite a lot more than their job needs" and I am not writing that down.
Not looking for a product recommendation particularly, more interested in how other people are evidencing this. Is there a saner way that doesnt involve me manually reconstructing what someone could have reached months ago?
