Aloha all!

I have come across a couple of C5 sites which have been hacked, evidently due to poor file permissions (which is of no fault of Concrete5). I was wondering if there are any add-ons or security auditing tools which make it easy to check the entire Concrete5 installation to ensure that the file permissions are solid. Anybody know of such a thing or should I write it myself?

Thanks in advance!
Cheers,

Alex
