17 WordPress Security Tips You Must Know

WordPress Security

Securing a WordPress website is crucial to protect it from potential threats and vulnerabilities. WordPress is a popular content management system (CMS) that powers a significant portion of the web, making it a prime target for hackers. In this comprehensive guide, we will explore various strategies and best practices to enhance the security of your WordPress website.

1. Keep WordPress Core, Themes, and Plugins Updated:

Regularly updating your WordPress core, themes, and plugins is one of the simplest yet most effective ways to enhance security. Developers frequently release updates to patch vulnerabilities and improve the overall security of their products. Thus, ensure automatic updates are enabled, and regularly check for updates manually if necessary.

2. Use Strong Authentication

Implementing strong authentication methods adds an extra layer of protection. Therefore, use complex passwords for all user accounts, including administrators, editors, and contributors. In addition, consider using two-factor authentication (2FA) to add an additional layer of security by requiring users to verify their identity through a secondary method, such as a mobile app or email.

3. Secure File Permissions

Proper file and directory permissions are crucial for preventing unauthorized access. Therefore, set file permissions to the minimum necessary level, allowing only authorized users to read, write, and execute files. The recommended file permission settings for directories are 755, and for files, it’s 644. Avoid using 777 permissions as it grants too much access.

4. Backup Your Website Regularly:

Regular backups are a vital component of a solid security strategy. In the event of a security breach or data loss, having a recent backup ensures that you can quickly restore your website to a previous state. Thus, use reliable backup plugins or services and store backups in secure off-site locations.

5. Install a WordPress Security Plugin

Numerous security plugins are available for WordPress that can enhance the security of your website. Examples include Wordfence, Sucuri Security, and iThemes Security. These plugins offer features such as firewall protection, malware scanning, and login attempt monitoring. As such, choose a reputable security plugin and configure it according to best practices.

6. Implement a Web Application Firewall (WAF)

A Web Application Firewall is designed to filter and block malicious traffic before it reaches your website. WAFs can protect against various online threats, including SQL injection, cross-site scripting (XSS), and distributed denial-of-service (DDoS) attacks. Some hosting providers such as HostZion offer built-in WAFs, or you can use third-party services.

7. SSL/TLS Encryption

Secure Sockets Layer (SSL) or its successor, Transport Layer Security (TLS), encrypts data transmitted between the user’s browser and your website server. This encryption is crucial for securing sensitive information such as login credentials and payment details. Therefore, acquire an SSL certificate and ensure that your website uses HTTPS.

8. Limit Login Attempts

Brute force attacks involve repeatedly attempting to log in to a website using various username and password combinations. Limiting the number of login attempts helps thwart these attacks. Moreover, implementing this restriction can be done through plugins or by configuring server settings.

9. Disable Directory Listing

By default, web servers may display the contents of directories if an index file (like index.html) is not present. Disable directory listing to prevent hackers from gaining insights into your file structure. This can be achieved by adding or modifying directives in your web server configuration file.

10. Disable XML-RPC

XML-RPC is a feature that allows external applications to communicate with your WordPress site. While it can be useful for certain functionalities, it is also a common target for attacks. Therefore, if you don’t need XML-RPC, consider disabling it to reduce the attack surface.

11. Monitor User Activity

Keep an eye on user activity, especially for administrative users. Moreso, regularly review user accounts and audit their roles and permissions. Consequently, if there are inactive or suspicious accounts, remove or restrict them immediately.

12. Choose a Reliable Hosting Provider

The security of your WordPress website is also influenced by your hosting provider. Opt for a reputable hosting company like HostZion that emphasizes security measures, offers regular server updates, and provides support for the latest PHP and MySQL versions.

13. WordPress Security Headers

Utilize security headers to enhance your website’s protection against common web vulnerabilities. Headers like Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Content-Type-Options can mitigate risks associated with cross-site scripting and other attacks.

14. Regular WordPress Security Audits

Conduct regular security audits of your website. This involves scanning for vulnerabilities, reviewing logs, and checking for outdated software. Use tools like security scanners and follow industry best practices to ensure that your website remains secure over time.

15. Educate Users and Administrators

Human error is a significant factor in security breaches. Educate users and administrators about best security practices, such as not clicking on suspicious links, using strong passwords, and being cautious with user privileges.

16. Isolate Environments

If you run multiple websites, consider isolating them from each other. This prevents a security breach on one site from affecting others. Virtual private server (VPS) environments and dedicated servers offer better isolation compared to shared hosting. However, if you choose to use shared hosting, you will need to consider using a more robust hosting provider like HostZion. This is because HostZion offers advanced isolation for shared hosting accounts.

17. Stay Informed About Security Threats

The landscape of cybersecurity is constantly evolving. Therefore, always stay informed about the latest security threats and vulnerabilities by following security blogs, forums, and official WordPress announcements. This is because being aware of potential risks allows you to proactively address them.


In conclusion, securing a WordPress website requires a multi-faceted approach that combines technical measures, user education, and proactive management. By implementing these strategies and staying vigilant, you can significantly reduce the risk of security breaches and ensure the continued integrity of your WordPress website.

Regularly reassess your security measures in response to emerging threats and updates in the cybersecurity landscape. Remember that a secure website is an ongoing commitment rather than a one-time task.
