"Profiles" preference?

I have been using Macintosh for decades now, and something new has appeared unbidden. In System Preferences I have a new preference pane entitled "Profiles." I have read about this pane but never seen it. It is next to "Start up Disk."

When I open the Profiles pane, I see one "provisioning profile" in there. It is for iMovie_27_Sep. In green letters the panel says Verified. The dated "Received" is seven minutes ago.

I do not knowingly use iMovie, but a week or two ago it appeared in Software Update. I am not aware of downloading an upgrade.

Is this new Profiles good? Or should I worry about it?
