[SOLVED] Permissions safety check in linux?

Issue

What is the quickest way to check the permissions of several folders and files in /home to see if any accounts have permissions set to an unsafe value?

What would be considered unsafe?

• files that have access levels that could potentially be written to from the public
• read access to .htaccess, .svn, etc files
• any files that may otherwise compromise the safety of the web server

EDIT

I think this is a two-part question. I've mentioned what I think is unsafe above, but perhaps it should also be asked: what else could make a site unsafe on a permissions level? What are the risk and how do you check for them?

Solution

Obvious answer:

find -L /home -perm 0777

Prints out all the files/directories with the mode 0777, typically a mode you don't want set.

More specific:

find -L /home -perm /o+w 

All files/directories that can be written to by anyone.

find -L /home -perm /o+r -name '.*' -type f

All files that start with a . that can be read by anyone

any files that may otherwise compromise the safety of the web server

There's not going to be any comprehensive way of quickly determining this.
