Preventing logged out users from accessing buddypress navigation pages

Found this thread

I will also like to prevent logged out users from access to activity, members, groups and blogs. I followed the thread but seeing we are now about 7 months later I am thinking that the codes have somewhat changed so I don’t want to risk messing anything up.

Can someone verify if I can still use this same method and achieve the same results that Tammie advised?

Also is it a good idea to put these changes in bp-daily/library/components/buddypress/buddypress-navigation.php or can this same file be copied to the child instead? And do I use the same directory structure?

My setup is as follows…

buddypress 1.2.7 bp-daily 3.9.2 wordpress 3.0.3
