11 Key Tips for WordPress Website Security

Security of WordPress

The security of WordPress websites has always been a crucial concern for website owners. With its market share accounting for nearly 40% of all websites, it often becomes a target for hackers and malicious software. Any vulnerabilities in the core software, plugins, or improper hosting and login credentials management can expose the site to malware or Trojan attacks. If a website is compromised without the owner’s knowledge, it might be blacklisted by Google or, worse, become a tool for fraudulent activities.

Recently, scam groups have impersonated online banking websites, sending text messages requesting users to update their account information, thereby stealing their credentials. Many banks have issued warnings, urging customers to remain vigilant. I have personally encountered a similar situation where my website was hacked, and some pages were replaced with phishing content. Fortunately, the issue was detected in time, preventing further damage.

Therefore, once a website is live, it should follow multiple security practices to minimize the risk of attacks and avoid penalties from Google’s search algorithms. If the website contains member data, ensuring data security becomes even more critical. Here are some key methods to enhance the security of your WordPress site:

  1. Website Backup: Keeping a clean backup of your site after it goes live is crucial. This way, even if the site is hacked, it can be quickly restored to a safe state. For frequently updated sites, it’s advisable to set up automated backups and store them in cloud storage.

  2. Choosing a Secure Hosting Provider: Website security doesn’t rely solely on WordPress security plugins; the hosting provider’s security features are equally important. Opt for hosting services with firewalls, DDoS protection, and other security measures to significantly reduce the risk of attacks.

  3. Strengthen Admin Username and Password: Change the default admin username and avoid using simple passwords. Tools like KeePassXC can help you securely store and manage complex passwords.

  4. Change the Admin Login URL: Install plugins like WPS Hide Login to change the default WordPress admin login URL, making it harder for hackers to locate the login page.

  5. Avoid Using Unverified Themes or Plugins: Always choose official or certified plugins and themes. Using unverified sources can introduce malicious software into your site, posing significant security risks.

  6. Protect the wp-config.php File: This file contains sensitive site settings. Adjust its permissions and configure server rules to prevent unauthorized access.

  7. Disable XML-RPC: If XML-RPC is not needed, it should be disabled to prevent the website from being exploited for DDoS attacks or other malicious activities.

  8. Enable SSL Certificates: SSL encryption ensures that data transmission between users and the server remains secure, boosting your site’s trustworthiness and SEO ranking on Google.

  9. Use the Latest PHP Version: Updating to the latest PHP version helps avoid the risks associated with unsupported older versions and their vulnerabilities.

  10. Keep Themes and Plugins Up to Date: Regularly update your site’s themes and plugins to fix known vulnerabilities and ensure stability and security.

  11. Regularly Update the WordPress Core: As an open-source platform, WordPress is a common target for hackers due to its widespread use. However, the open-source nature also allows the community to report bugs and security issues, which the development team continuously addresses. To keep your site secure, it’s important to update WordPress to the latest version to patch known vulnerabilities. Before upgrading, make sure to evaluate whether all plugins are compatible with the new version and back up the entire site to prevent any issues during the upgrade process.

Implementing these methods can greatly improve the security of a WordPress website, ensuring it remains both visually appealing and structurally secure. As the website grows, balancing feature expansion with continuous security maintenance is crucial to ward off potential cyber threats and ensure optimal site performance.
