WordPress is one of the most popular content management systems (CMS) in the world, powering over 30% of all websites. While WordPress is known for its ease of use and flexibility, it is also a popular target for hackers and cybercriminals. Therefore, it is essential to take WordPress security seriously and implement best practices to protect your website from potential threats.
WordPress security is a complex topic that requires a multi-layered approach. There are several fundamental security practices that website owners should follow to secure their WordPress site. These include keeping WordPress and all plugins and themes up to date, using strong passwords, and limiting user access and permissions.
In addition to these fundamental practices, there are advanced security measures that website owners can implement to further enhance their WordPress security. These measures include using a web application firewall (WAF), implementing SSL/HTTPS, and regularly backing up your website. By following these best practices, website owners can significantly reduce the risk of a security breach and keep their WordPress site secure.
Key Takeaways
- WordPress security requires a multi-layered approach, including fundamental security practices and advanced security measures.
- Fundamental security practices include keeping WordPress and all plugins and themes up to date, using strong passwords, and limiting user access and permissions.
- Advanced security measures include using a web application firewall (WAF), implementing SSL/HTTPS, and regularly backing up your website.
WordPress Security Fundamentals
Use Strong Passwords
One of the most basic and essential steps in securing a WordPress site is using strong passwords. A strong password consists of a combination of uppercase and lowercase letters, numbers, and special characters. It should be at least 12 characters long and unique to each account.
WordPress provides a built-in password strength meter that evaluates the strength of a password and provides feedback to users. It is recommended to use a password manager to generate and store complex passwords.
Keep WordPress Updated
Keeping WordPress up to date is crucial for maintaining website security. WordPress releases regular updates that include security patches, bug fixes, and new features. Failure to update WordPress, themes, and plugins can leave your site vulnerable to security threats.
WordPress offers automatic updates for minor releases, but it is recommended to manually update major releases. Before updating, it is essential to backup the website to avoid data loss.
Implement SSL Encryption
Implementing SSL encryption is an essential step in securing a WordPress site. SSL encryption secures data in transit between the user’s browser and the server. It encrypts sensitive information such as login credentials, credit card details, and personal data.
To implement SSL encryption, a website owner needs to obtain an SSL certificate from a trusted certificate authority and install it on the server. It is recommended to use a reputable web hosting provider that offers SSL encryption as part of their hosting plans.
By implementing these WordPress security fundamentals, website owners can significantly reduce the risk of security breaches and protect their site from malicious attacks.
Securing WordPress Configuration
Protect wp-config.php
The wp-config.php file contains sensitive information such as database credentials, security keys and salts, and other configuration settings. It is crucial to protect this file from unauthorized access. Here are a few best practices to secure the wp-config.php file:
- Move
wp-config.phpto a directory outside of the public_html or www folder. This will prevent anyone from accessing the file through the browser. - Set file permissions to 400 or 440 to limit access to the file.
- Add the following code to the
.htaccessfile to restrict access to thewp-config.phpfile:
<files wp-config.php>
order allow,deny
deny from all
</files>
- Use security plugins that offer additional protection for the
wp-config.phpfile.
Disable File Editing
By default, WordPress allows administrators to edit plugin and theme files from within the WordPress dashboard. While this feature can be convenient, it can also be a security risk if someone gains unauthorized access to the dashboard. Disabling file editing can prevent attackers from modifying plugin or theme files. Here’s how to disable file editing:
- Add the following code to the
wp-config.phpfile:
define( 'DISALLOW_FILE_EDIT', true );
- Use security plugins that offer the option to disable file editing.
By following these best practices, website owners can significantly improve the security of their WordPress configuration.
User Access and Permissions
Limit Login Attempts
Limiting login attempts is an effective way to prevent brute force attacks on WordPress sites. Brute force attacks are automated attempts to guess a user’s login credentials by trying different combinations of usernames and passwords. By limiting the number of login attempts, attackers are prevented from making multiple attempts to guess the password.
WordPress users can limit login attempts by installing plugins such as Login Lockdown or Limit Login Attempts. These plugins allow users to set limits on the number of login attempts made from a particular IP address. Once the limit is reached, the user is locked out of the site for a specified period of time.
Enforce User Roles
Enforcing user roles is another best practice for securing WordPress sites. WordPress has six default user roles: Super Admin, Administrator, Editor, Author, Contributor, and Subscriber. Each role has different permissions and access levels.
Users should be assigned roles based on their responsibilities and the tasks they need to perform on the site. For example, a user who only needs to create and edit content should be assigned the Author role, while a user who needs to manage the site’s settings and plugins should be assigned the Administrator role.
WordPress users can enforce user roles by using plugins such as User Role Editor or Members. These plugins allow users to create custom roles and assign permissions to each role. By enforcing user roles, users are prevented from accessing areas of the site they do not have permission to access.
Advanced Security Measures
Set Up a Web Application Firewall
A web application firewall (WAF) is a security tool that monitors and filters incoming and outgoing traffic to your website. It helps to protect your website from various types of attacks such as cross-site scripting (XSS), SQL injection, and brute force attacks. A WAF can also block malicious traffic and prevent unauthorized access to your website.
There are several WAFs available for WordPress, both free and paid. Cloudflare is a popular choice among WordPress users as it adds a lot of security layers that block common attacks. Sucuri is another popular WAF that provides comprehensive security for your website.
Regularly Scan for Malware
Regularly scanning your website for malware is another important step in securing your WordPress site. Malware can infect your website through vulnerable plugins, themes, or outdated WordPress versions. It can cause your website to malfunction, steal sensitive data, or even harm your visitors.
There are several WordPress security plugins available that can help you scan your website for malware. Wordfence is a popular security plugin that provides malware scanning, firewall protection, and other security features. Sucuri is another security plugin that provides malware scanning, website monitoring, and other security features.
In addition to using security plugins, it is also important to keep your WordPress site up-to-date with the latest versions of WordPress, plugins, and themes. This helps to ensure that your website is protected against known vulnerabilities and security threats.
