#  Introduction 

Normally a user can use the **ps** command to see any process running on a system.  
A nice additional security measure is to hide these processes.   
A user may be able to "see" only her own processes thanks to the **security.curtain** sysctl option. 

#  Execution

Run following command as a user with root privileges: 
    
    # sysctl -w security.curtain=1
    

Now type as normal user: 
    
    # ps auxww
    

You should be able to see only processes belonging to your user.
