Did you know that an average WordPress website is attacked every 22 minutes? With more and more people learning online, your WordPress Learning Management System (LMS) is more than just a website. It’s a place where you store private student data, useful course materials, and maybe even financial data. In fact, WordPress websites receive over 90,000 attacks each minute, with a whopping 43% of hacks targeting small and medium-sized enterprises, including online course creators. With sensitive student data, payment information, and intellectual property at stake, a single vulnerability can result in catastrophic breaches.
Protecting your digital classroom is no longer an option; it’s a must. This thorough guide will provide you with actionable techniques and best practices for fortifying your WordPress LMS against the ever-changing risks of hackers and data breaches, resulting in a secure and trustworthy learning environment for both students and teachers.
WordPress Security Checklist
The key to website security, and hence WordPress LMS security, is to follow the suggested protocols. Although there is no guarantee that you will not encounter problems, doing so reduces the likelihood of them occurring significantly.
Protecting your WordPress LMS does not have to be complicated. Our checklist simplifies everything down into simple steps. Following it will ensure the security and trustworthiness of your online learning platform, giving you and your students peace of mind.
✅ Update core WordPress, plugins, and themes
✅ Securing the login procedure
✅ Reliable Hosting
✅ Enable SSL/HTTPS
✅ Use of security plugins
✅ Remove unused/outdated plugins & themes
✅ Defining user roles
✅ Securing file and directory permissions
✅ Disable XML-RPC
✅ Installing a Web Application Firewall (WAF)
1- Updating
Updating your core WordPress, PHP version, plugins, and themes is critical. These have new security patches and performance enhancements.
Core WordPress
One of the easiest methods to increase WordPress LMS security is to update your core WordPress version.
Log in to your WordPress admin panel, then select Dashboard > Updates from the menu on the left to see if a WordPress update is available. We strongly advise you to upgrade as soon as possible if one is available.
Updating Themes
One of the leading causes of compromised security is outdated themes. To update themes, go to Appearance > Themes and click Update.
Updating Plugins
Another big factor in WordPress LMS breaches is outdated plugins. For a detailed guide on updating plugins, refer to one of our posts, “How to Install and Update WordPress Plugins—Easy Guide for Beginners.”
Disclaimer: We strongly advise you to make a Backup and roll the updates on a testing environment first. If you wish to know how to set up a testing environment, please refer to our post “The Step-by-Step Guide to Testing Your WordPress Website Like an Expert.”
2- Securing Login Procedure
We ranked this high in the checklist because it is one of the most crucial aspects of keeping your LMS secure. It is fundamental to keeping your accounts secure from malicious login attempts.
- Use of Strong Passwords: Weak passwords expose your website to botnets and unwanted access. Virus-infected computers controlled by hackers are called botnets. You can enforce a password policy that would make the user set strong passwords that can not be easily brute-forced.
- Limit Login Attempts: Limiting the number of login attempts a user can make on incorrect credentials also greatly reduces any chance of brute-force attacks, making your LMS safe. Some hosting has it by default; if not, you can use the Limit Login Attempts plugin to set it up.
- Enable two-factor authentication (2FA): 2FA requires a second device to verify sign-on. It is one of the easiest and most effective login security methods.
- Use captcha: It will add another layer of security to your LMS platform. It ensures that the login attempt is indeed made by a person and not a bot.
3- Reliable Hosting Provider
One of the first lines of defense against hackers and data breaches is your hosting provider. A secure, high-performance hosting provider is more than simply a speed boost; it is the cornerstone for your LMS security. Consider it like designing a bank vault: no matter how tight your lock (plugins/passwords), a weak doorframe (server) allows hackers to break through.
What should you look for in a good hosting provider? Let’s list it down!
- Reliable hosts automatically patch operating system and server flaws, preventing hacker exploits.
- Premium hosting protects your site if another site on the server is compromised. A single compromised site on low-end shared hosting can compromise all sites.
- Most reliable providers feature scheduled backups so that you may restore your LMS in minutes rather than hours or days.
- DDoS attacks can disable your website. Top hosting companies have DDoS mitigation to keep your LMS running and handle high traffic.
- Security issues occur outside business hours. A reliable host offers 24/7 support to help you respond to threats and limit damage.
- Safe hosts allow you to create a staging area to test your new updates without breaking your live LMS.
Here are some suggestions for LMS-Friendly hosting providers.
4- Enable SSL/TLS
SSL (Secure Sockets Layer) is the gold-standard encryption technique that establishes a secure connection between your WordPress site and your users’ browsers. Without it, hackers can intercept login passwords, financial information, and student data as they transit over the Internet.
Today, SSL has mostly been replaced by a more modern version called TLS (Transport Layer Security), but the term SSL is still commonly used.
Most good hosting providers offer free SSL certificates. You may need to access your hosting provider’s control panel and enable an SSL certificate from the security section. After that, you can use a plugin like Really Simple SSL. This plugin automatically detects your SSL certificate and updates your URLs to use HTTPS.
5- Using Security Plugins
We also recommend using a good security plugin. Wordfence is a very good choice. On average, it blocks approximately 202 million attacks per day, making it a highly reliable plugin.
It provides an array of security features, such as:
- Monitors login attempts to stop unauthorized access.
- Scans core files, themes, and plugins for malware, bad URLs, backdoors, SEO spam, and code injections.
- It blocks harmful traffic from reaching your site with its firewall.
- Automatically updates Wordfence and assists with plugin security updates.
- It supports two-factor authentication, is compatible with Cloudflare, and uses a Content Delivery Network (CDN) that speeds up and secures websites.
6- Remove The Unused Themes & Plugins
Keeping Unused Themes & Plugins is a Major Security Risk for Your WordPress LMS. Unused themes and plugins are like unlocked backdoors for hackers, even if disabled. According to WPScan, plugins and themes account for 99% of all vulnerabilities on your WordPress platform.
To remove an unused plugin, follow these steps:
Note: The Delete button will only appear after you deactivate the plugin.
To remove an unused theme, follow these steps:
7- Define User Roles Properly
A WordPress LMS (Learning Management System) handles sensitive information, including student records, payments, certifications, and course content. Without appropriate user role descriptions, you risk instructors accidentally deleting courses, students accessing admin panels, or accounts being hijacked, resulting in data breaches.
To define user roles, follow these steps:
To edit those user roles, you can download the Members plugin.
That’s how simple it is to assign user role privileges.
Using a Plugin to Divide Content
You can also use a third-party plugin to categorize the content displayed to the general public and enrolled students.
One such plugin is “Custom Tabs For LearnDash.” This plugin by LDninjas allows course creators to enhance their courses, lessons, topics, quizzes, and groups with unique customized tabs, making their courses very engaging and tailored to students’ needs. These tabs are displayed to the right of the default tabs and can contain anything from HTML, media ( images & videos ), and shortcodes.
8- Secure File and Directory Permissions
WordPress websites have files and directories with access and modification controls. Anyone with site access can view and modify files without these permissions. You have most likely seen the WordPress files and directories if you use cPanel or file transfer protocol (FTP) to access your website.
Generally speaking, 644 for files and 755 for folders are the appropriate file permission values for WordPress. However, there are times when you may want to secure your files further, as is frequently the case with the .htaccess and wp-config.php files.
In conclusion, WordPress users should restrict server file access and modification. Recommended WordPress file permissions are:
9- Disable XML-RPC
One of many WordPress features is remote content publishing. This is done through XML-RPC, and you may need to keep it enabled if you use the WordPress app, Jetpack plugin, or trackbacks and pingbacks.
Though it is a safe feature, hackers using brute force attacks often exploit XML-RPC to access your website. The easiest way to disable XML-RPC is through the plugin.
To disable it, follow these steps:
10- Installing a Web Application Firewall (WAF)
Another effective way to defend your LMS against hacking attempts is to use a Web Application Firewall (WAF). This allows you to ban dubious IP addresses and filter all incoming traffic.
You can be sure that hackers won’t even be able to get to your LMS because it has a defense mechanism that acts as a wall. If you are using Wordfence, then it has the firewall active by default. However, you can optimize the firewall using the premium version of Wordfence. You can refer to the Optimizing the Firewall guide from Wordfence for further firewall optimization.
11- Remove Inactive Users
If you have inactive user accounts, your website may become cluttered and pose security risks. Users are generally considered inactive if they haven’t signed into their account in the last 90 days. These accounts should be removed for security concerns. There’s a chance that these old passwords have already been leaked onto the dark web.
To remove these inactive users, follow these steps:
13- Hide wp-admin / wp-login.php Page
Another first line of defence you can take is hiding the login page address to prevent hackers from making attempts. WordPress assigns the login page address to your domain name by default with the suffix wp-admin or wp-login.php.
Changing your LMS’s default login page address can prevent hackers from attempting to log in. The most straightforward way is to do it through a plugin. You can use WPS Hide Login. Once you change the URL, only share it with the people you trust.
14- Backup
Lastly, making regular backups is the most crucial part of ensuring your LMS platform stays live. If your LMS is hacked, you can promptly restore the older backup after resetting your credentials. This will ensure that your LMS platform always stays live and accessible to your students.
You can manually create database backups, but the most straightforward method is to use your security plugin. One of the most reliable and well-reputed backup plugins is UpdraftPlus. If you wish to know how to create backups using Updraft Plus, refer to their documentation here.
