A Detailed WordPress Website Security Checklist for 2024

While many website owners are fully aware of the importance of following good website security practices in order to protect sensitive information and customer data from hackers, the truth is that the vast majority of those website owners don’t actually follow a good security plan that works.

You see, website security goes way beyond simply setting secure passwords or enabling two-factor authentication to log in. Did you know that only 8% of WordPress breaches happen?

Web hackers and cybercriminals are simply becoming far more sophisticated than ever before, and the result of that is websites and blogs across the internet are becoming increasingly vulnerable as well.

But the good news is that when it comes to website security, there are a large number of different things that you can do to beef up your defenses to stop hackers and reduce your vulnerabilities, and that’s what we’re going to talk about today by going over a series of steps and strategies you can use to greatly increase the security of your website.

10 Website Security Checklist to Setup the Perfect Security Strategy

Here are some basic steps you can take to develop a website security strategy that actually works:

  • Stop Brute Force Log-In Attempts
  • Watch Out For SQL Injection
  • Choose A Secure Hosting Platform
  • Use The Latest Version of Plugins
  • Install An SSL Certificate
  • Update WordPress Version Regularly
  • Use Secure WP-Admin Login Credentials
  • Set Up Safelist and Blocklist for the Admin Page
  • Use Trusted WordPress Themes
  • Remove Unused WordPress Plugins and Themes.

Lets see them in details-

Stop Brute Force Log-In Attempts

One of the most common threats that website owners face each day is hackers bombarding them with brute force log-in attempts.

A brute force log-in attempt is where hackers will use specialized software to try every combination of symbols, numbers, characters, and letters until they find a combination that allows them access.

So long as your website utilizes user authentication, odds are good that you will one day become the target of a brute force attack if you haven’t already.

Fortunately, there are a few methods at your disposal to stop brute force attacks. The simplest way is to only allow users a limited number of login attempts within a specified time period.

However, the issue with this method is that the hacker can lock out vast quantities of user accounts, which will then cause a DoS (denial of service).

An even better method that you can use is to log out an entire IP address after a sufficient number of failed login attempts. Or alternatively, another method you can use will be to design your website to direct the user to an “HTTP 401” error page after an insufficient number of login attempts.

Watch Out For SQL Injection

An SQL injection attack is a code injection hacking technique where a cybercriminal will attempt to insert SQL (structured query language) statements into input fields.

The reason they will be able to accomplish this is because of poor coding in your web applications that leaves them vulnerable.

To stop an SQL injection before it happens, therefore, you will need to utilize typed and parameterized database queries, which you can accomplish using a programming language such as PHP or Java, among others.

Choose A Secure Hosting Platform

One of the most important factors to consider when choosing a web host is security.

That being said, there’s not just one security factor to consider with a web host, but rather several.

At the bare minimum, you will want to choose a web host that offers you each and every one of the following security practices, presented in alphabetical order:

  • Firewalls
  • DDoS Protection
  • Domain Name Privacy
  • Spam Filter
  • Virus Protection

Out of these, one of the most important is the firewall or a piece of software that is designed to filter requests to your web server. They will then block certain requests, based on a variety of factors before they reach your web server.

DDoS Protection is also particularly important to have. A DDoS, or Distributed Denial of Service, attack is where thousands of requests will be sent to your website simultaneously, which overloads the website and causes it to shut down.

DDoS protection from your web host of choice will analyze DDoS activity on your website to block certain requests while enabling legitimate traffic to get through. That being said, while most web hosting providers offer firewalls, not all offer DDoS protection services, so be careful about your selection.

Use The Latest Version of Plugins

Updating your plugins is another critically important security strategy to follow. The longer your plugins go without receiving an update, the far more likely they are to have vulnerabilities to hacking.

This is because the developers of reputable website plugins are always working hard being the clock to patch vulnerabilities and update their plugins to keep them less exposed to attack.

That being said, over four out of every five WordPress websites don’t even have updated plugins,  even though updating them is one of the easiest security procedures to do.

All that you will have to do to update your plugin is to go to the ‘Plugins’ tab (if you are running WordPress) in the dashboard, and then check to see if any of your plugins are out of date.

If any are, you simply select ‘Update Now’ and you’re all set. Simple, right? And yet it’s astonishing that the majority of WordPress website owners don’t do it.

Install An SSL Certificate

Last but not least, another important security step to follow will be to install an SSL certificate.

An SSL certificate is simply a data file that will bind a cryptographic key to your web server’s detail. This activates the HTTPS protocol, which allows secure connections between your server and the web browser.

While SSL certificates are commonly used to protect financial data and information, they are still very important to use regardless of which type of website you are running.

Update WordPress Version Regularly

Regular software updates from WordPress are crucial for enhancing performance and fortifying security, effectively safeguarding your site against cyber threats.

Updating your WordPress version stands out as one of the simplest and most effective measures to bolster security. Despite this, approximately 50% of WordPress sites persist in running older versions, leaving them more vulnerable to potential threats.

To check whether your WordPress version is up to date, log in to your WordPress admin area and navigate to Dashboard → Updates on the left menu panel. If it indicates that your version is not current, we strongly recommend updating it promptly.


It's essential to stay vigilant about future update release dates to ensure your site remains free from running outdated WordPress versions. Additionally, we advise keeping your themes and plugins up to date. Outdated themes and plugins can lead to conflicts with the newly updated WordPress core software, resulting in errors and increased susceptibility to security threats.

Follow these straightforward steps to address outdated themes and plugins:

  • Navigate to your WordPress admin panel and go to Dashboard → Updates.
  • Scroll down to the Plugins and Themes sections, reviewing the list of themes and plugins ready for updates. Note that you can update them collectively or individually.
  • Click “Update Plugins” to ensure that your WordPress site remains secure and operates smoothly with the latest software versions.

Use Secure WP-Admin Login Credentials

Frequently, users make a common mistake by employing easily guessable usernames like “admin,” “administrator,” or “test,” thereby elevating the risk of their site falling prey to brute force attacks. In addition to this, attackers often leverage such vulnerabilities to target WordPress sites lacking robust password protection.

To enhance your site's security, we strongly recommend adopting a unique and complex username-password combination. As an alternative, consider following these steps to establish a new WordPress administrator account featuring a distinctive username:

  • From your WordPress Dashboard, navigate to UsersAdd New.
  • Create a new user and assign it the Administrator role. Add a password and hit the Add New User button once you’re done.

Set Up Safelist and Blocklist for the Admin Page

Securing your login page against unauthorized access and potential brute force attacks can be achieved by implementing URL lockdown. This involves utilizing a Web Application Firewall (WAF) service tailored for WordPress, such as Cloudflare or Sucuri.

When using Cloudflare, you can configure a zone lockdown rule to enhance your site's security. This rule allows you to define specific URLs that you want to lockdown, along with specifying the permitted IP range that can access these URLs. Consequently, individuals outside the designated IP range will be unable to access the specified URLs.

Use Trusted WordPress Themes

Nulled WordPress themes are unauthorized replicas of the original premium themes, often marketed at lower prices to entice users. However, these themes typically come with a myriad of security issues.

Frequently, providers of nulled themes turn out to be hackers who have compromised the original premium themes by embedding malicious code, including malware and spam links. Additionally, these themes may serve as potential backdoors for other exploits, posing a threat to the security of your WordPress site.

Best Free WordPress Blog Themes

Given that nulled themes are distributed illegally, users do not receive any support from the legitimate developers. This implies that in case of any issues with your site, you'll need to troubleshoot and secure your WordPress site independently.

To mitigate the risk of being targeted by hackers, we strongly advise selecting a WordPress theme from its official repository or reputable developers. Alternatively, consider exploring third-party themes in recognized theme marketplaces like ThemeForest, where a vast selection of premium themes is available, ensuring both quality and security.

Remove Unused WordPress Plugins and Themes

Keeping unused plugins and themes on the site can be harmful, especially if the plugins and themes haven’t been updated. Outdated plugins and themes increase the risk of cyberattacks as hackers can use them to gain access to your site.

Follow these steps to delete an unused WordPress plugin:

  • Navigate to PluginsInstalled Plugins.
  • You’ll see the list of all installed plugins. Click Delete under the plugin’s name.

Note that the delete button will only be available after deactivating the plugin.

Meanwhile, here are the steps to delete an unused theme:

  • From your WordPress admin dashboard, go to AppearanceThemes.
  • Click on the theme you want to delete. 
  • A pop-up window will appear, showing the theme details. Click the Delete button on the bottom-right corner.

You can follow these to create the perfect WordPress website security checklist.

Bonus: How to Utilize WordPress Website Security Using WordPress Security Plugins

WordPress has quite a few effective security plugins to help you secure your website. These plugins will make your work easy and you can take care of the complex tasks without any technical knowledge.

Here is how you can utilize the WordPress plugins-

  • Enable Two-Factor Authentication for WP-Admin: With a plugin like WordFence Security, you can enable two-factor authentication. It will add a second layer of protection to your WordPress site.
  • Back-Up WordPress Regularly: Due to WordPress or plugin/theme updates, your site can break or you can lose any data. With a WordPress plugin, you can keep a backup of your website regularly.
  • Limit Login Attempts: WordPress allows unlimited attempts to log in and it opens up to outside attacks. You can use a plugin like Loginizer, to limit the login attempts.
  • Change the WordPress Login Page URL: Every WordPress website shares the same default login URL: yourdomain.com/wp-admin. Relying on this default login URL can make it susceptible to hacking attempts, as it provides a predictable target for attackers. To enhance security, plugins such as WPS Hide Login and Change wp-admin Login offer the option to customize your login URL
  • Monitor User Activity: What your users are doing it is also an important part of website security. There are quite a few WordPress activity log plugins to help you with that.
