To add weight to a discussion I'm having, I'm trying to find concrete examples of why having the /root directory world readable is bad from a security point of view.I have found plenty of instances online of people repeating the mantra that it's really not good to give /root say, 755 perms, but with no further evidence.Could someone please provide a scenario where a system's security can be compromised if this is the case? The less contrived the better - so, for example, how can a freshly installed Centos system suffer if /root has 755 perms?EDIT - Thanks for the replies, but so far no concrete examples. To put it another way, how could you use the fact that /root is visible to compromise the system? Are there any examples of programs being installed and assuming that /root is not accessible to everyone?EDIT 2 - I think the consensus so far is that it's not a great security risk, other than someone not checking perms and using the directory as if it were private to root.
