Introduction to Joomla!

Joomla! is the second most popular Content Management System (CMS) in the world, powering roughly 3.3% of the websites on the interwebs. A PHP based open source CMS launched in 2005 as a fork of Mambo, Joomla! has grown in popularity over the years courtesy to its simplicity and ease of use, extensibility, size of community and security.
Although Joomla! as a system is considered fairly secure, it has been subject to security breaches over the years. Here is a breakdown of the most commonly known vulnerabilities for Joomla!,

  1. Vulnerabilities in the Code or Code Execution Flaws
  2. SQL Injection Attacks

While the CMS being used plays an important role when it comes to security there are certain steps that a web administrator can take to minimise the risk of a security breach, some of these include,

  1. Updating Passwords regularly or not using the same password across the entire setup.
  2. Updating the Core Files, Theme Files and Extensions as and when new updates are released.
  3. Not going the extra mile to further harden the security of the system.
  4. Not taking regular back-ups.
  5. Not going through security documentation and coding recommendations put forward by Joomla!

Here is a list of 10 extensions suggested by our team of Joomla! developers that you can use to further enhance the security of a Joomla! setup,

  1. Akeeba Backup
