The </del>access <del style="font-weight: bold; text-decoration: none;">control log showed one event.

The outermost layer typically covers the building perimeter and parking areas, followed by lobby and hallway access control, then server </del>room <del style="font-weight: bold; text-decoration: none;">doors, and finally individual rack enclosures. Each layer uses a different verification method so that defeating one does not automatically grant access to the next. A visitor might swipe a badge to enter the building, but reaching the server room requires a second credential plus biometric confirmation, and opening a specific rack requires yet another authorization tied to that person's role</del>.

This integration is one of the more technically involved parts of a layered deployment and is usually where working with an experienced data center security systems integrator pays off, since misconfigured RFID zones are a common source of false positives</ins>.</div></td></tr> <!-- diff cache key 2d4chan:diff:1.41:old-1020044:rev-1020059:php=table --> </table>
