Hi Hiep,

i installed apache on centos 5 and i have some questions regarding security for apache. i read security tips on http://httpd.apache.org/docs/2.2/misc/security_tips.html and get the idea, but still need some advices from guru here.

/etc/httpd/conf/httpd.conf:
ServerRoot "/etc/httpd"
User apache
Group apache
DocumentRoot "/var/www/html"

as of now, /var/www/html/ belongs to root user & group.

Make this apache:apache, it fits better with the User/Group specifiers above.

is there any security risk by changing /var/www/html/ to apache:apache?
how are the developers upload/download  files?
should i create a user/group and let all of them use this user to upload/download files?


but i have couple developers here that need to upload files to this folder that i don't want to give out the root password. what should i change /var/www/html/ folder to?

Use apache:apache if you think that all developers are trustworthy ;-) Definitely not root:root. When you make the ownership change, verify that apache:apache may indeed read /var/www/html/.
how do i verify this?


i also have a SSI folder (/var/www/html/includes) that i don't want any web user to have access to because these includes files contain user/password to mysql.
for example, at the beginning of /var/www/html/index.php, i have:
<?
include_once('/var/www/html/includes/global.php');
include_once('/var/www/html/includes/connect.php');
?>

PHP includes this way locally, from the file system. There is no need to park these files in the docroot tree. E.g., stick them in /var/www/includes/, outside of /var/www/html. Then use include_once('/var/www/includes/global.php').

i try to prevent web user doing this:
wget http://10.0.0.120/includes/global.php
but at the same time allow apache server to access files in /var/www/html/inclues/ folder.

Definitely a good idea ;-)
See above..
HTH,
