Securing your Joomla Website During Installation

Protecting your Joomla website during installation could be kind of hard. In this JovialGuide, we have broken everything down for you to be able to understand.

The following 3 sections of this post, will teach you how to keep your Joomla website safe during installation.

Choose a Reliable Web Hosting Company That is Configured for Strong Security

Your web hosting provider contributes greatly to most of the vulnerabilities in your Joomla website. Choosing a reliable web hosting provider that is configured for security should be the first thing you should always have in mind when choosing a hosting company for your Joomla website.

Another thing you should understand about website hosting is the difference between shared hosting and managed hosting.

Shared hosting is the cheapest hosting plan and recommended for small websites. If you host your website on a shared hosting server, your website will become vulnerable to attacks at anytime, since every other website is hosted on the same shared hosting server as your own. Since you are sharing the same server with other website owners, an attack on any website may affect your website.

Managed hosting is more secure than shared hosting because you are not sharing the same web server as every other website. When you pay for a managed hosting plan, you are given a properly configured and secure webserver for your Joomla website with expert support. At this time, you don’t have to worry about the technical aspects of your Joomla website, they are done by your web hosting experts. The other side of managed hosting is that it’s very expensive compared to shared hosting.

We always recommend SiteGround because of their properly configured webserver for security. Their excellent web hosting services have made them to be an official web hosting provider for WordPress (recommended by If you are unsure how reliable and secure SiteGround is for Joomla, see the 5 best reasons you should transfer or host your Joomla website with SiteGround

Joomla Website Installation

This section is the most important section of all. Because it has to do with your website login details and database configuration settings.

The Joomla installation processes are grouped into 3 stages. These stages are:

  • the main configuration stage (first stage)
  • the database configuration stage (second stage)
  • and the overview stage (final stage)

Let’s look at them one after the other, starting from the main configuration stage.

The Main Configuration Stage

Main configuration stage in Joomla installation

This stage lets you enter the site name, description, super user username, email, and password. In this JovialGuide, we are only concentrating on the super user account details (email, username and password).

Create a New Email Account

We recommend you create a new email account with a very complex password, specially for your Joomla website. This new email account will not be used for any other website/verification, but only used as the Email account of the super user of your Joomla website.

Choose a Smart Username

You are to choose a name that would be used as the username of the super user. This should be a name that is only known to you.

Choose a strong password

When we say a strong password, we mean a complex password that cannot be pronounced. Avoid using words such as: admin, pass, adminpass, 12345, abcde, 00000, etc. Also stay away from using your name, date of birth, pet name, best friend’s name, etc, as your password. They are easy-to-guess! Using a complex password that cannot be pronounced or guessed hardens your Joomla website!

Your password should be at least 10 characters, made up of alphabets (capital and small letters), numbers, special characters (example ¦¬{~), multiplication sign, division sign, etc. Your password should at least look like this: )_=IDjk?^+382sGFU@%_. Our password example contains numbers, letters (upper and lower case), and special characters, resulting to a total of 20 characters. With this example, your attacker will find it pretty hard to guess or crack your password.

The Database Configuration Stage

Database configuration in Joomla installation

The database configuration stage (of Joomla installation) gives you the ability to specify the name of your Joomla database, username of the database, password of the database, host name, table prefix and an option to remove or backup old tables from previous Joomla installation. In this post, our concentration are on database password and table prefix. They are the important ones in Joomla security.

Database Password

Your database password must always be as strong as a rock. Or, even stronger than a rock! For strong security, it should be a combination of letters (upper and lower cases), numbers and special characters. This alone makes it pretty hard for any attacker to get into your Joomla database.

Table Prefix

A database table prefix or table prefix is a string added to the name of the table of your website. It helps you run more than one or multiple installations on just one database.

Enter a complex prefix into the table prefix field. It should be a combination of letters and numbers only, resulting to a total of 5 characters. It should be complex enough such that no one can guess it. Your table prefix should look something like this: g24yf.

One last thing you should note is that your database prefix should always end with an under-score sign (_). Your table prefix with an under-score will look like this g24yf_ . That is the standard way of writing a table prefix.

The Overview Stage

The overview page/stage is the last stage in Joomla installation. This page shows you all of the things you did during the installation of Joomla (main configuration stage and the database configuration stage). It also shows you other vital information you need to know about your Joomla website.

If any item is marked no, we recommend you contact your web hosting provider for it to be corrected. Else, it will affect your website’s performance.

Final Words on – Securing Joomla Website During Installation

Though, Joomla is a pretty secure Content Management System (CMS), it has its own vulnerabilities that could be exploited. This means that no website is free from vulnerabilities and no website has 100% security.
