10 tips to secure your joomla site
Author Admin
Proper Hosting Environment
A properly configured server is highly recommended for your joomla website. Host your site on a server that runs PHP in CGI mode with su_php. This means that PHP runs under your own account user instead of the global Apache user and you don’t need to set insecure global permissions like CHMOD of 777.
a. Set register_globals OFF
b. Disable allow_url_fopen
c. Adjust the magic_quotes_gpc directive as needed for your site. The recommended setting for Joomla! 1.0.x is ON to protect against poorly-written extensions. Joomla! 1.5 ignores this setting and works fine either way.
d. Don’t use PHP safe_mode
Change the Default Database Prefix (jos_)
While installation, change the default database prefix to something random. This will prevent most of the SQL injection attacks as hackers try to retrive superadmin details from jos_users table. Disable FTP Layer
While installation, dont enable the FTP layer as it opens up a potential security hole since your FTP details are stored in plain text under a Joomla! configuration file. FTP layer is not required if your hosting is secured and configured properly for Joomla. Change superadministrator username
After installation, change the username for the super-administrator. By default, its admin. So change it something like ravi.chamria so that the username/password combination becomes difficult to guess or crack. Strong password
Always use strong password for the administrator accounts. An example of strong password is E@^M!$ <9@k. You can use sites like www.strongpasswordgenerator.com to generate a strong password.
A good addition is to password protect the administrator folder. In apache web server, you can do this htaccess file or in cpanel, you can use Password Protected Directory option to setup a password. This will add another layer of username/password before someone reaches your Joomla admin details. Needless to say, have this password different from Joomla admin password.
Enable SEF URLs
Most hackers use the Google inurl: command to search for a vulnerable exploit. So enable SEF urls from site configuration if you are using Joomla 1.5. You can also use extensions like SH404SEF for both Joomla 1.0 and Joomla 1.5. This will prevent hackers from finding the exploits as well as benefit you in SEO perspective. Upgrade to latest release of Joomla
Always upgrade to the latest release of Joomla as soon as possible. The current release is 1.5.11. You can subscribe to http://feeds.joomla.org/JoomlaSecurityNews or our blog feeds http://feeds2.feedburner.com/joomlainblog to get updates about the latest security releases.
Always download Joomla! from official sites, such as the Joomla! Forge, and check the MD5 hash
Third party extensions
There are more than 4000 extensions available for Joomla many of which are non-commercial. But dont take this as an opportunity to install unnecessary extensions on your website. Remember that most hacking attempts occur due to vulnerability in these extensions. So, always use extensions which are popular, has strong community backing and development process. Proper file/folder permissions
The proper file/folder permissions for your joomla website is:
* PHP files: 644
* Config files: 666
* Other folders: 755
You can CHMOD the files and folders using your FTP client.
Setup a backup and recovery process
Always rely on a strong backup and recovery protocol for your live website. Its not just hacking that may compromise your website but other factors like a faulty upgrade or extension install, hardware failure, hosting provider issues. You can use JoomlaPack, a non-commercial component native for both Joomla 1.0 and 1.5 for backup.

We hear you’ve written some new digital photography titles. What’s the story behind these books?
Wiley Publishing is releasing three new books of mine, Creative Close-Ups: Digital Photography Tips & Techniques , Creative Night: Digital Photography Tips & Techniques , and Creative Composition: Digital Photography Tips & Techniques . My idea with these books was to help people become better photographers by presenting the subject of digital photography in a different way.
They say that cameras don’t take photos, people do. It’s really true. Someone with a great eye can take masterful photos with an inexpensive camera. Therefore, it is important to know something about photo technique, but the really amazing thing is that we can conceptualize and come up with these bits and bytes that make up a photo—and they can be meaningful to people. I try to help people come up with images that are relevant and meaningful. Cameras and hardware are just tools. What’s with all the photos in these books?
Well, everyone likes to look at striking images, so one thing my photos do in these books is get people’s attention. However, the photos play another role as well. Each photo in my book is accompanied by the story of how the photo was made and the technical data related to the photo. That way, if you’re not ready to dive into the text itself, you can learn a lot just by browsing the photos. My feeling is that you truly do learn about photography by looking at photos. It’s much more important to look at images you admire and try and figure out why you like them than it is to read about photography. The photos in these books are baked into the DNA of the teaching strategy. By browsing through the pages, someone can learn a great deal and have an enjoyable visual experience at the same time. What’s the most important thing that readers can get out of your new books?
I want to inspire readers to be the most creative and best photographers they can be. If you pick up one of my books, I hope you can make use of the technical content and see how the photos relate to some of your own work. The most important thing, however, is to take the ideas in the book, get out there, and do some really peddle-to-the-metal creative photography.
