Before you invest in access control

The gap between knowing this and actually doing it is where most teams lose ground. Before you spend anything on access control, it is worth confirming a few things are already true.

Security is a maintenance habit rather than a purchase, which is why it drifts. Assume whoever inherits this will have half your context and none of your patience.

Prerequisites

• You can describe the outcome you want in one sentence
• Someone owns it after the work is done
• Give the least access that lets someone do their job
• You have a way to tell whether it worked

What to watch for

Review who has access when people change roles. Getting it slightly wrong is survivable. Ignoring it entirely is not. The failure mode is not doing it wrong, it is doing it once and assuming it stays done.

Shared logins destroy accountability. That sounds obvious written down. It is still the thing most often skipped. Doing this properly once is usually cheaper than doing it approximately three times.

How to tell if yours is fine

The realistic threat for most small businesses is automated and opportunistic, not targeted. Three things worth confirming about access control before you move on:

• Someone can say what the current setup is without going to look
• Give the least access that lets someone do their job — and you know whether that is true here
• There is a way to tell whether the last change to this helped

Worth checking on your own setup before it becomes someone else's problem to fix.
