Keep an eye on the patterns, not the objects. Check for anything that deviates from the normal flow—odd timing, mismatched logs, or a sudden drop in activity where there should be none. Use layered detection, so if one sensor fails, another catches it. And always keep a small, dedicated audit team that can question the obvious before it becomes a problem.

Look at any login or transaction that occurs outside the usual hours—say 11 pm to 5 am. Flag any IP that appears in multiple geo‑regions in a short span. In logs, keep an eye on failed authentication bursts, sudden drops in sensor data, and any changes to privileged user accounts that aren’t accompanied by a proper change‑request note. Those are the first red‑flags.
