Remove user permission for specific folder

Question

I have created folder in home. I have also created new user.

I want that specific folder can only be accessed by the new created user. I want to remove root privileges for that folder.

I am using this command to give ownership to that user

chown -R newUser:newUser folder_name

It is changing the ownership to new user but it is still accessible by other users. I want that it can only be accessed by new user and root and not by the previously created users.

Answer 1

You can't revoke access permissions from root. It's special user that by design should access almost everything.
