In today's digital age, where the internet plays a vital role in our everyday lives, the importance of website security has reached unprecedented levels. With the increasing number of cyber threats and attacks, ensuring the security of your WordPress website is paramount. Common security risks specific to WordPress include vulnerabilities in themes and plugins, weak user credentials, insufficient file permissions, and the lack of regular backups.
To mitigate these risks, you have to stay proactive. Keep your WordPress themes and plugins updated, choose strong user credentials, enable two-factor authentication, regularly update the WordPress core, set appropriate file permissions, and implement a reliable backup strategy.
Read on as we discuss 10 effective measures for enhancing security and protecting your prized WordPress website.
Assess Your Current Website Security
Assessing website security involves evaluating weaknesses in infrastructure, applications, and security measures. It includes vulnerability scanning, penetration testing, code review, authentication and access controls, network assessment, updates and patches, employee training, and incident response planning.
Strengthen User Access Control
To enhance user access control for WordPress, follow these recommended practices:
- Use strong usernames and passwords, enforcing complexity requirements.
- Limit user privileges by assigning appropriate roles and permissions.
- Keep WordPress and plugins updated to patch security vulnerabilities.
- Implement two-factor authentication (2FA) for added security.
- Limit login attempts to prevent brute force attacks.
- Monitor user activity to detect suspicious behavior.
- Disable file editing to prevent unauthorized code modifications.
- Secure user registration to prevent spam and ensure authenticity.
- Use HTTPS to encrypt user communications.
- Backup your site to protect against security incidents and data loss regularly.
Keep WordPress Core, Themes, and Plugins Updated
It's recommended to update WordPress Core through the admin dashboard. However, before doing so, it's always good practice to back up your data in case anything goes wrong.
Next, it is recommended to keep official themes or themes from trustworthy sources up to date. You can easily do this through the admin dashboard by checking for available updates and applying them accordingly.
Similarly, for plugins, it's important to keep them updated to ensure optimal functionality and security. You can update plugins through the admin dashboard as well, where you can view the available updates and proceed with the installation.
Implement Secure Hosting Practices
Follow these secure hosting steps and safeguard your website from potential threats:
- Choose a reputable hosting provider that offers secure hosting environments and necessary security features.
- Keep your server software up to date, including the operating system, web server software, and PHP, to address vulnerabilities.
- Use secure file transfer protocols like SFTP or SSH instead of unencrypted options like FTP.
- Use strong and unique credentials for your hosting account, database, and server, and consider utilizing a password manager.
- Configure file permissions properly to restrict access to sensitive files and directories.
- Implement a Web Application Firewall (WAF) to filter and block malicious web traffic.
- Enable HTTPS with an SSL/TLS certificate to encrypt data transmission between your website and visitors.
- Back up your WordPress files and databases to an off-site location regularly.
- Monitor server logs for suspicious activity to detect potential security issues.
- Stay updated with security advisories related to your hosting environment to remain informed about emerging threats.
Secure the WordPress Admin Area
Here are some key measures to enhance the security of your WordPress admin control:
- Use strong login credentials with unique usernames and strong passwords, avoiding common choices. Consider implementing two-factor authentication for added security.
- Change the default admin URL to make it more difficult for attackers to target. Use plugins or custom code to modify the login URL.
- Limit login attempts by using plugins or security solutions that restrict the number of login tries from a single IP address.
- Restrict access to the admin area by allowing only specific IP addresses or ranges to access it.
- Enable SSL/TLS encryption (HTTPS) with a valid certificate to encrypt communication and prevent unauthorized interception of sensitive information.
- Protect the wp-admin directory by using server configuration files like .htaccess to restrict access, such as limiting by IP address or implementing password protection.
- Implement a web application firewall (WAF) to detect and block malicious traffic targeting the admin area, including common attack vectors.
- Update WordPress and plugins to apply the latest security patches and bug fixes regularly.
- Monitor and log activity in the admin area to identify any suspicious behavior or unauthorized access attempts.
- Choose a reputable hosting provider that offers a secure hosting environment with proper security measures in place, such as firewalls, intrusion detection systems, and regular server updates.
Protect Against Malware and Hacks
Here are a few essential steps you can take:
- Use Reliable Themes and Plugins – Obtain themes and plugins from reputable sources like the official WordPress repository or well-known developers. Regularly update them to ensure you have the latest versions equipped with necessary security patches.

- Use Security Plugins – Install security plugins specifically designed for WordPress websites. These plugins offer features like malware scanning, firewall protection, and login security enhancements.
- Perform Regular Backups – Create backups of your entire WordPress website, including files and the database, on a regular basis. Store these backups in a secure location separate from your website server.
- Monitor for Suspicious Activity – Set up a system to monitor your website for any suspicious activity or unauthorized access attempts. Monitor log files, review security reports, and consider using intrusion detection systems.
- Educate Yourself and Your Users – Stay informed about the latest security practices and threats in the WordPress ecosystem. Educate your users on basic security measures such as identifying and avoiding phishing emails, using strong passwords, and being cautious when installing unknown themes or plugins.
Harden Your Website's File and Directory Permissions
Some key recommendations for hardening permissions in a WordPress website include:
- Directory Permissions – Set directories to 755 using the command chmod 755 directory_name.
- File Permissions – Set PHP files (including WordPress core files) to 644 using the command chmod 644 file_name.
- Wp-config.php – Protect sensitive information by setting its permission to 600 using the command chmod 600 wp-config.php.
- .htaccess – Set its permission to 644 as it contains important configuration directives. Use the command chmod 644 .htaccess.
