Network Access
Network Access records who and what authenticated onto your network — the MAC, the user, the switch or access point, the port, the SSID, and how they got on. It answers questions no amount of device polling can: did that laptop authenticate by 802.1X or MAB, and which policy let it on?
The source is Aruba ClearPass, which sends its RADIUS accounting to your site collector.

Turning it on
Network Access is an optional module and is off by default. Switch it on under Settings → Modules.
Enabling the module isn't enough. The Network Access entry stays hidden from the menu until a ClearPass connection is configured — so if you've enabled it and still can't see it, that's why. See Setting up ClearPass.
Two things worth knowing up front
No ClearPass credentials are stored. The integration is one-way syslog: ClearPass sends to your collector. JOATOS holds no ClearPass username, password, or API token — there's nothing to rotate and nothing to leak.
History is kept, not fetched. Records are stored as they arrive, so the log stays fast and still shows history even when ClearPass or the collector is down. The flip side is that there's no backfill — you'll see what has arrived since you set it up, not what happened before.
