WordPress Security Explained

Learn why WordPress is a secure web platform for building and running your business online …

WordPress Security OverviewIn 2013, WordPress installations around the world were subjected to a global-scale brute force attack.

These attacks were caused by computers infected with viruses and programmed to attack other vulnerable installations (called “botnets”).

WordPress is often the target of attacks by hackers

On March 11, 2014, many technology sites began reporting that 162,000 WordPress-powered sites had been hacked.

According to the Cnet report,

“With some old-fashioned trickery, hackers were able to get more than 162,000 legitimate WordPress-powered Web sites to mount a distributed-denial-of-service attack against another Web site.”

As described by security firm Sucuri, hackers had leveraged a well-known flaw to attack unsuspecting WordPress sites and direct a distributed-denial-of-service cyber attack (DDoS) towards another popular website.

Whenever worldwide brute-force attacks happen on WordPress sites, it’s natural for website owners to start questioning just how safe and secure WordPress is as a software for running their websites.

Being the world’s most used CMS makes WordPress an obvious target for hacking attacks. But do you really need to be concerned about WordPress as being a secure platform for building your business website?

In this article, you will learn some of the main reasons why you should definitely choose WordPress if you have any concerns about website security.

WordPress Security Explained

Let’s start by looking at facts …

Thousands of websites and blogs are hacked every year … not just WordPress sites!

The sheer number of attacks on websites and blogs worldwide is rising, and things are only going to get worse.

It’s safe to assume that if your website or blog hasn’t been hacked yet, then it’s only a matter of time … regardless of the web platform your website has been built with!

Since it’s not a matter of if, but a matter of when before your website is targeted by malicious hackers, are there any advantages that WordPress can offer you in terms of security?

How Vulnerable Are “Open Source” Software Programs?

Some people argue that WordPress cannot be a safe platform for building and running a web presence because it’s a freely available open source software.

Open source CMS programs like WordPress, Drupal and Joomla are free to use and anyone can access the underlying software code.

The argument against using WordPress, then, goes something like this: If everyone can study the Open Source code for WordPress, then hackers can also easily obtain all of the code and study every single line, looking for security weaknesses in the code that can be exploited …

It's no longer a matter of if, but when before your website is targeted by hackers ... WordPress or no WordPress!

(It’s no longer a matter of if, but when before your website will be targeted by hackers … WordPress or no WordPress!)

While it’s true that WordPress is a free program and hackers can easily access it and study the code looking for weaknesses or vulnerabilities (hackers can do the same with any software program), the fact that WordPress is a free, open software platform actually makes it a whole lot more secure in many ways.

This is because WordPress has the support of a community consisting of thousands of people such as software programmers, plugin developers and theme designers who are constantly working to help to improve the platform and make WordPress more secure …

With WordPress, a huge community of volunteers worldwide is responsible for keeping the platform up-to-date.

WordPress continually evolves because of the effort of a global community working around the clock to fix any issues detected by users. It benefits from thousands of web developers, designers and users committed to improving the software, identifying and fixing security holes and making the WordPress platform safer for every user …

The moment that a security vulnerability is identified by developers or users, these are then logged in user forums and addressed by the WordPress developers …

The WordPress community support system, therefore, is quite formidable and anyone can help contribute to securing the software.

For example:

  • If you discover bugs or a security exploit, you can report these by emailing security@wordpress.org.
  • If you find issues in a WP plugin, you can report these by sending an email to plugins@wordpress.org.

This is one of the reasons why the WordPress team releases new version updates so frequently, and why you need to keep your WordPress sites and blogs regularly maintained …

WordPress CMS Vs Proprietary Platforms

Compare what we have just discussed above with proprietary platforms where often the responsibility for maintaining software security, fixing bugs, etc. falls to a smaller team of developers with limited resources and you will quickly realize the value and advantages of using WordPress to run your business web presence on a secure platform.

The WordPress CMS is free to download, modify and use, and hundreds of volunteers and expert developers work on improving the software. Can a proprietary CMS company afford to employ as many developers and programmers and still deliver users software that is 100% free to download, use and modify as they wish?

WordPress Vs Other Open Source CMS Applications

CMS Platforms

(CMS Platforms)

Whilst on the topic of Open Source content management applications, there is valid research to support the fact that the WordPress CMS is actually safer than other leading Open Source CMS platforms such as Drupal and Joomla.

For example, the chart below shows the number of security vulnerabilities discovered in each of these CMS platforms …

Other research shows that, because WordPress is quite easy to use and maintain, when sites across different CMS platforms were tested for security issues, sites run on WordPress had a significant degree of less exposure to risk …

WordPress Should Not Be Blamed

Whenever WordPress sites are attacked, you shouldn’t be too quick to place the blame on WordPress.

According to a report called “Compromised Websites: An Owner’s Perspective,” which is published by security organizations Commtouch and StopBadware, a large number of website owners have no idea about the security threats their websites are exposed to, how to secure a website, or deal with compromised web security.

In fact, over 60% of webmasters surveyed in this report didn’t know how their sites were hacked after an attack …

Many webmasters don't know how their websites got hacked.

Of immediate concern, however, is the fact that most security problems seem to be related to site owners running sites with an outdated version of WordPress …

Many security issues come from sites running outdated WordPress versions.

When WordPress security issues were looked at in more detail, it was found that only a small percentage of vulnerabilities discovered in third-party code are actually found in the WordPress CMS core, while 70% – 80% percent of all security issues are found in plug-ins and extensions created by third-party developers …

Like all robust web platforms, WordPress is regularly updated to deal with new security threats that may arise. Improving security is always a concern, and to that end, you should always keep your WordPress site, plugins, and themes up-to-date.

WordPress … Secure Enough For Banks To Use!

The amount of misinformation about how secure WordPress is has even led the co-founder of WordPress, Matt Mullenweg, to chime in and reply to posts online.

In a blog post entitled “A Bank Website on WordPress” published on April 15, 2015, Matt wrote the following about WordPress …

There’s a thread on Quora asking “I am powering a bank’s website using WordPress. What security measures should I take?” The answers have mostly been ignorant junk along the lines of “Oh NOES WP is INSECURE! let me take my money out of that bank”, so I wrote one myself, which I’ve copied below.

I agree there’s probably not a ton of benefit to having the online banking / billpay / etc portion of a bank’s website on WordPress, however there is no reason you couldn’t run the front-end and marketing side of the site on WordPress, and in fact you’d be leveraging WordPress’ strength as a content management platform that is flexible, customizable, and easy to update and maintain.

Matt then goes on to provide a couple of security tips, before stating the following …

For an example of a beautiful, responsive banking website built on WordPress, check out Gateway Bank of Mesa AZ. WordPress is also trusted to run sites for some of the largest and most security-conscious organizations in the world, including Facebook, SAP, Glenn Greenwald’s The Intercept, eBay, McAfee, Sophos, GNOME, Mozilla, MIT, Reuters, CNN, Google Ventures, NASA, and literally hundreds more.

As the most widely used CMS in the world, many people use and deploy the open source version of WordPress in a sub-optimal and insecure way, but the same could be said of Linux, Apache, MySQL, Node, Rails, Java, or any widely-used software. It is possible and actually not that hard to run WordPress in a way that is secure enough for a bank, government site, media site, or anything.

Millions of businesses around the world, including banks, global corporations and e-commerce sites use WordPress to build their websites, not just bloggers.

Other Issues Affecting Site Security

Other studies on issues that play a role in WordPress security point to areas such as:

  • No platform is completely safe from security threats. As many as 90% of all websites across all platforms are vulnerable to attack, mostly due to using outdated software.
  • The biggest security risk in all web platforms seems to be the users themselves. For example, many users ignore good password security practices.
  • Lack of constant system monitoring. All security systems need frequent monitoring, testing, updating and improvement.
  • Server setup. For example, sites on shared webhosting servers are only as safe as the least secure site on the grid, so if another user on your shared server gets their site hacked into, then every site on your shared server can potentially become vulnerable.

There’s No Reason To Avoid Using WordPress

As this article has hopefully shown, WordPress is quite secure. As long as you implement basic security measures and keep your WordPress software (and themes, plugins, etc.) regularly updated, there’s really no reason not to use WordPress to run your web site or blog.
