Turn off network settings and power button in lock screen

[kaki2308]

Hello

How I can turn off all these buttons in lock screen (when I'm not logged in). I mean: network settings, power putton and ease of access.
I marked them by red color on image.


I don't want to anyone coud turn off or change my settings (like turn off wifi).
