default permissions for new group policy objects

our GPO infrastructure has grown over the years and each admin has done its own type of work.
now i have to cleanup all those delegation settings.

what are the default settings and which ones are recommended for having high security?

i know,whenever I create a new GPO the following Active Directory system groups are granted access:
- Authenticated Users
- Domain Admins
- Enterprise Admins

by default.can or should i remove any of these and which ones would make sense to ad?

Can you be a little more specific. Are you trying to harden desktops, IE, server...etc?

You should not change any of those permissions unless you need to. For example, you may want to limit what objects process a GPO. You would remove authenticated users and add in the objects (or the objects group).

If you are wanting a way to manage who does what with Group policy, look up advanced group policy management.
