ps -aux after su

[asus8420]

Can you help me with configuration grsec, please.
Probably to make so the user would not see another's process even after does su?

I have one more problem.
After install i switch grsec to learning mode, but after reboot grsec is disable.
#gradm -S
The RBAC system is currently disabled.
How to make grsec always enable?
Thanks
