Joomla! is a popular Content Management System (CMS) having the second largest user base in the earth and the Internet is a really big, big, big thing. As good things coming in this area, bad things also surfaces. One of the worst thing among them is the security flaws that make websites vulnerable to exploit.

Security is a huge matter. It is not possible to make the security 100% flawless by following any standards. Because, security hole can surface not only in software, but also in hardware-level. However, the hope is that security experts have asked to follow some steps regarding stepping up securities.

The Joomla! Team is very serious about security. Whenever any security vulnerability is found, they fix it and release a fix immediately. On their official websites and in many seminars, they have provided many guidelines using various means to ensure the security of the websites.

There is NO perfect Security Measures, but, all we can do is to do our best to secure our Joomla! powered websites. In this blog post, I have compiled these security measures to help you raise the security level and safeguard your website.

Security Measures From Within Joomla! CMS

Use a strong password for Super Admin

In most of the cases, users keep the default “admin” username and password during installation and forget to change it to something rock-solid later. This is a seriously a bad practice.

Do not use common, guessable words for passwords, like, love, god, pass, admin, admin123, etc.

Use a online password generator which will give you unlimited, random strong passwords, like, Norton Password Generator, or, Secure Password Generator.

Protect your Administrator page URL

The URL to access Joomla! Administrator page is known to all, Wrap up this URL in a camouflage to protect it from everyone! Use a free Joomla! plugin, AdminExile by Using AdminExile, administrator URL will take the form something like, 

Reading its document, will give you detailed information.

Use Two-Factor Authentication

Enable Two-Factor Authentication on your Joomla! site. It will provide an extra level of security beside conventional login system. If anyone get a hold on to your credential, they still need a code that is generated on every 30 seconds and the owner of the website has the app that generates the code. There is a detailed discussion on Two-Factory Authentication on Joomla!’s website.

Use the latest Joomla! version

Whenever Joomla! released a new version, whether a major, minor or security fix release, you will receive notification from your website about the new release. In almost every new release, there are scores of bug fixed and few security fixes. It’s most important to update your Joomla! website as soon as possible.

Failing to update in time, you keep your website open to known security vulnerability.

Use the latest version of extensions you use

All major Joomla! extension providers use extension update server as per Joomla! standard. Whenever any extension provider publishes new release of any extension, as a users of that extension, an owner of a Joomla! website receives notification when he/she logs in in administrator area. Keep your extensions up-to-date when you see such update notice.

Do not use illegal “Nulled” copy of paid Joomla! extensions

Use extensions from trusted providers. Many users tend to get Joomla! extensions from various websites run by unscrupulous people. These extensions are stuffed with evil code punched into the extensions to get compromise host server and get away with valuable information like credit card info, users info, product info, etc.

If you run e-commerce business, blog than run Google Adsense, do not even think of using nulled or illegal copy of paid Joomla! extensions. Using such extensions will leave your website to various exploits and poses serious security holes.

Get rid of unused users

Disable, block or even delete all the user accounts which are not used any more.

Many times, super user accounts are created for website developers. When the development work is done, these types of accounts will create a security threat for your site. Therefore, it is desirable to delete these types of user accounts as soon as possible.

Disable Error Reporting from Global Configuration on Production Website

Error Reporting is enabled on the default Joomla installation. However, after migrating to the production server, this setting has to be disabled. Because, if there is a script error in the production level, it shows some information about that script with some detailed information on the script, which helps hackers to penetrate the security of the site.

In Global Configuration of Joomla!, click on Server tab and you can turn off error reporting in just one click.

Error Reporting in Joomla! must be disabled.

In order to improve the security of the website, the developers’ routine work list must contain a line to stop this error reporting option.

Security Measures outside Joomla!

Host on a reputable hosting providers

Most of the cheap hosting companies sell re-seller hosting through year-end offers and sell them into small packages. Most of them have no experience in hosting business. They just manage the hosting business solely from a commercial perspective. So, take advantage of the hosting service from a good hosting company, without being deceived in the flashy AD.

Rochen, Siteground, InMotion are good hosting service provider to name a few who are specialized in hosting setup favorable for Joomla! websites. Furthermore, you could get a good Virtual Private Server (VPS) if you are confident to set up one. Digital Ocean and RamNode are two good VPS provider.

Set proper file/folder permission

Due to the fact that most web servers are in Linux, there must be sufficient knowledge on how to set permissions on files and folders in this operating system. Otherwise, setting a permissions incorrectly means that the security of your Joomla! site is blown like a cotton in the air. Generally, the permissions of files, folders, and particularly, configuration.php must be set as follows:

  • Set the permissions for your Joomla folders to 755
  • Set the permissions for your Joomla files to 644
  • Set the permissions for your configuration.php file to 444
  • Never use 777 (full access) permissions!

From System Information menu item in Joomla!, your Joomla! website will provide many important information. By clicking on the Folder Permissions tab, it is easy to see and know whether Joomla! File and folder permissions are set correctly on the production server!

After the Joomla!-powered website is deployed, this checkup must be kept in the developer’s security routine checkup.

Backup your Joomla Site often

It is the quickest and best mean to bring your website back online again from the last backup you had taken.

The backup system can be automated in Akeeba Backup. Even backup files can be stored in Dropbox and made automated after a certain time interval.

Cloudflare is one of the CDN that you can use freely, beside its commercial packages for more advanced users. One of the benefit of Cloudflare CDN is that it saves your website from a level of DDOS attack, unethical attemp to comprise your website, serves the content of your website when your server is down, and many more.
