the problem with your /var/www/html permissions is the user/group "apache"
can write to directories and files. which can be used by anyone on the
internet(bad guys) to use potentially exploitable dynamic
pages(.php/.cgi/etc) to add/modify files on your server. this is a bad
thing. SELinux may offer some protections.
i would:
chmod -R g-w /var/www/html
chown -R somewebuser /var/www/html
(replace somewebuser with the unix user account to modify the website.)
