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.
