How to add read permission access to /conf/sevenup

[AEMWizard]

Hello there, 

I have a folder in /conf/sevenup, and I wish to give "everyone group" this resource + all it's children "READ" permission. Programmatically, how can we achieve this?

This is just a one time activity and why do you want to add maintenance overhead via code?
