1.  Are you running PHP apps on the web server?  Perl apps?  Bad code in
dynamic apps is the main way security breaches happen if via apache.
And in those cases is usually the ability to execute some script
(sometimes one that the bad guys upload first) that is the issue.  Many
times this happens because programmers of the dynamic (php, perl,
python, ruby, etc.) do not properly vet the input of some form or other

2.  Why have password logins at all?  Using a secure ssh key only for
logins makes the most sense.

3.  Please do not top post.
