2025 WordPress Security Audit Checklist

By following a structured WordPress Security Audit Checklist, website owners can proactively prevent attacks, safeguard sensitive data, maintain SEO performance, and protect their brand reputation. Below, we discuss 10 essential steps every WordPress website should follow during a comprehensive security audit in 2025.

1. Update WordPress Core, Themes, and Plugins

One of the most overlooked yet critical steps in a WordPress Security Audit is ensuring that the WordPress core, all installed themes, and plugins are up to date. Cybercriminals frequently exploit outdated software with known vulnerabilities, making neglected updates one of the easiest ways for hackers to gain access. WordPress regularly releases updates not just for new features, but primarily to address security issues and patch vulnerabilities. Similarly, themes and plugins especially widely used ones can become major entry points for attackers if they are outdated or unsupported. Before making updates, it’s recommended to use best wordpress backup plugins to secure your site and prevent data loss.

During your WordPress Security Audit, it is essential to:

• Verify the WordPress Core Version: Ensure your website runs the latest stable version of WordPress to benefit from all security patches.
• Update Themes and Plugins: Regularly update all active themes and plugins to prevent known exploits.
• Remove Unused or Inactive Components: Unused plugins and themes, even if inactive, can still be vulnerable to attacks. Removing them reduces your website’s attack surface.
• Check for Automatic Updates: Enable automatic updates where possible, especially for minor security patches, to ensure timely protection.
• Test After Updates: After updating, verify that your website functions correctly and that no compatibility issues arise.

Maintaining updated software during a WordPress Security Audit not only strengthens your site’s defenses but also enhances overall performance and stability. This proactive step lays the foundation for a secure, resilient WordPress website capable of withstanding evolving cyber threats. 

2. Conduct a Comprehensive User Role and Permission Audit

User management is a critical aspect of a WordPress Security Audit. Websites often accumulate multiple user accounts over time, many of which might have higher privileges than necessary. Excessive admin or editor-level access increases the likelihood of accidental or malicious misuse, making it essential to review all accounts carefully. Conducting a comprehensive audit involves verifying each user’s role, assessing whether their access is still required, and removing inactive or suspicious accounts. Enforcing strong password policies ensures that each user maintains a secure login, reducing the risk of unauthorized access. Using best website hosting for WordPress can also reduce server-level vulnerabilities.

Limiting permissions to only what is necessary for a user’s specific role minimizes exposure to potential brute-force attacks and insider threats. For example, contributors or authors should not have admin-level capabilities, and any elevated privileges should be granted only on a temporary or conditional basis.

Additional steps to enhance security during this audit include:

• Enable Two-Factor Authentication (2FA): Adds an extra layer of protection for admin and privileged accounts.
• Regularly Review User Activity: Monitor login attempts, failed access, and unusual behavior to detect potential breaches.
• Audit Role Assignments: Ensure users are assigned only the permissions necessary for their tasks.
• Remove Dormant Accounts: Deleting inactive users eliminates potential entry points for attackers.

By performing a detailed user role and permission audit, you strengthen your website’s defenses and ensure that your WordPress environment remains secure against both internal and external threats.

3. Implement Strong Password Policies

Weak passwords remain a leading cause of website breaches. During a WordPress Security Audit, evaluating the strength and management of passwords is critical to safeguarding your website from unauthorized access. Hackers frequently use brute-force attacks or credential-stuffing techniques to exploit weak or repeated passwords, which can compromise sensitive data, user accounts, and administrative controls. Ensuring that all users, especially those with administrative privileges, follow strong password practices is a foundational step in website security.

A strong password should:

• Combine uppercase and lowercase letters: This increases complexity and reduces predictability.
• Include numbers and special characters: Adding these elements makes passwords harder for automated attacks to guess.
• Have a minimum length of 12 characters: Longer passwords are exponentially more difficult to crack than short ones.

Avoid predictable patterns: Refrain from using sequential numbers, common words, or repeated passwords across accounts.

Beyond creating strong passwords, integrating a password manager can help users generate, store, and autofill secure credentials without relying on memory. Regularly enforcing password updates further minimizes risk from previously exposed credentials.

Combining strong passwords with two-factor authentication (2FA) adds an additional layer of protection, requiring verification beyond just the password itself. During a WordPress Security Audit, implementing these practices ensures your website is resistant to unauthorized logins, significantly reducing the chances of security breaches and maintaining the overall integrity of your site.

4. Scan for Malware and Vulnerabilities

A proactive WordPress Security Audit includes scanning your website for malware, viruses, and potential vulnerabilities. Modern malware can silently infect files, inject malicious scripts, or compromise sensitive databases without showing immediate signs, making regular scans essential for website safety. Scanning helps identify hidden threats before they escalate into severe security breaches, data loss, or performance issues.

To carry out an effective scan, leverage reliable tools such as Wordfence, Sucuri, or iThemes Security, which provide comprehensive detection of malware, suspicious code, and vulnerabilities in themes, plugins, and core files. These tools offer both manual and automated scanning options, allowing you to schedule regular checks without disrupting website functionality.

Key steps during this part of a WordPress Security Audit:

Perform Full Site Scans: Analyze all files, databases, and scripts for malware or anomalies.

Review Security Reports Carefully:

• Understand flagged issues, prioritize critical threats, and plan immediate remediation.
• Remove or Quarantine Infected Files: Prevent malware from spreading to other parts of your website.
• Update Vulnerable Components: Patch insecure plugins, themes, or WordPress core to close potential attack vectors.
• Schedule Regular Scans: Automated scans ensure continuous monitoring and early detection of new threats.

Regularly scanning your WordPress site ensures vulnerabilities are identified and addressed promptly, protecting sensitive data, maintaining website performance, and building visitor trust while strengthening overall security posture.

5. Review and Harden File Permissions

File and directory permissions are a critical aspect often overlooked in a WordPress Security Audit. Incorrect permissions can provide attackers or malicious scripts with the ability to modify crucial files, gain administrative access, or inject harmful code into your website. Ensuring proper permissions during a security audit is essential for protecting your site’s integrity and minimizing potential vulnerabilities.

During a WordPress Security Audit, begin by reviewing all sensitive files and directories. Critical files such as wp-config.php and .htaccess should have strict permissions to prevent unauthorized access. A general rule of thumb is that directories should have permissions set to 755, which allows the owner full control while restricting others to read and execute access only. Files, on the other hand, should typically be set to 644, giving the owner read and write permissions and limiting others to read-only access. Avoid using 777, as it grants full read, write, and execute permissions to anyone, significantly increasing the risk of hacks.

Other best practices include:

• Regularly auditing all file and folder permissions to detect deviations from recommended settings.
• Limiting access to sensitive directories for non-administrative users.
• Using security plugins to automate detection of incorrect permissions and alert you to potential vulnerabilities.
• Implementing server-level restrictions where possible to further protect critical files.

Hardening file permissions during a WordPress Security Audit is a foundational step in safeguarding your website from unauthorized modifications, malware injections, and potential breaches, ensuring a stronger and more secure web environment.

6. Secure the WordPress Login and Admin Area

The login page and admin dashboard are the most targeted areas for hackers. During a WordPress Security Audit, it is essential to implement measures that secure these critical access points, as they are the gateway to your website’s core functionality and sensitive data. Unauthorized access to the admin area can lead to website defacement, malware injection, data theft, or complete site compromise. Ensuring the login and admin areas are secure is therefore a priority in any thorough WordPress Security Audit.

Key steps to secure the WordPress login and admin area include:

Login URL Masking: Change the default login URL from /wp-admin or /wp-login.php to a custom URL. This makes it harder for automated bots and attackers to locate the login page.

• Limit Login Attempts: Restrict the number of login attempts per user to prevent brute-force attacks. Multiple failed login attempts should trigger temporary blocks or alerts.
• Monitor Login Activity: Track unusual login behavior, including repeated failed attempts or logins from unfamiliar IP addresses. Real-time monitoring can help identify potential security threats early.
• Enable Two-Factor Authentication (2FA): Adding 2FA requires users to provide an additional verification code during login, greatly reducing the risk of unauthorized access.
• Use reCAPTCHA or Similar Tools: Prevent automated bots from attempting to access the login page, protecting your site from malicious login attempts.

Regularly auditing the login and admin process during a WordPress Security Audit ensures your administrative area remains protected, significantly reducing the risk of attacks and maintaining overall website integrity.

7. Backup Strategy Review

A robust backup strategy is indispensable in any WordPress Security Audit. Even with the best security measures, unforeseen attacks, server failures, or accidental deletions can compromise your website. Backups serve as a safety net, allowing you to restore your site to a previous working state with minimal downtime and data loss. During a security audit, it is essential to evaluate the frequency, storage, and accessibility of backups. Websites with dynamic content, such as eCommerce platforms or blogs with frequent updates, require more frequent backups compared to static sites.

Ensure that backups are stored in secure off-site locations, such as cloud storage or external servers, rather than relying solely on the website server. This protects your data even if the primary server is compromised. Verify that you can restore your website quickly and efficiently, testing backup restorations periodically to ensure reliability.

Automated backup solutions integrated with WordPress, like UpdraftPlus or BackupBuddy, simplify the process by providing scheduled snapshots of your website and database.

Key considerations for a strong backup strategy during a WordPress Security Audit:

• Frequency: Daily, weekly, or real-time backups depending on website activity.
• Storage: Secure off-site locations, encrypted if possible.
• Restoration Testing: Regularly verify that backups can be restored successfully.
• Automation: Use reliable WordPress plugins for scheduled backups.
• Comprehensive Coverage: Include both files and databases in backups.

Implementing a strong backup strategy ensures that, in the event of an attack or failure, your website remains resilient and your data is fully recoverable.

8. SSL and HTTPS Verification

Securing data in transit is a vital component of a WordPress Security Audit. SSL certificates play a key role by encrypting the communication between a user’s browser and your server, ensuring that sensitive information such as login credentials, payment details, and personal data remains protected from eavesdropping, interception, or man-in-the-middle attacks. During the audit, it is crucial to verify that your SSL certificate is valid, correctly installed, and configured to cover all necessary subdomains. This ensures that no portion of your website is left vulnerable.

Additionally, make sure that all pages, particularly login forms, checkout pages, contact forms, and any page collecting sensitive information, are served over HTTPS rather than HTTP. Mixed content, where some elements load over HTTP, can compromise security and trigger browser warnings. Implementing HTTPS also has added benefits beyond security. Search engines like Google prioritize secure websites, so ensuring proper SSL implementation can improve your SEO rankings. Furthermore, displaying the padlock icon in browsers reassures visitors that your website is trustworthy and safe to use.

Key steps for SSL and HTTPS verification in a WordPress Security Audit include:

• Check that your SSL certificate is active and not expired.
• Confirm that all pages, forms, and assets load over HTTPS.
• Redirect all HTTP traffic to HTTPS automatically.
• Review subdomains to ensure they are included in the SSL coverage.
• Monitor for mixed content issues that could trigger browser warnings.

Proper SSL and HTTPS implementation is an essential step in maintaining a secure, credible, and SEO-friendly WordPress website.

9. Database Security Checks

WordPress relies heavily on its database to store content, user information, and site configurations. During a WordPress Security Audit, examining database security is crucial to safeguard your website against SQL injection attacks, unauthorized access, and other potential threats. Databases are often targeted by attackers because they contain the backbone of your website’s data, including sensitive user details and configuration settings. Strengthening database security helps maintain the integrity, availability, and confidentiality of your WordPress site.

Key steps to ensure database security during a WordPress Security Audit include:

• Change the Default Database Prefix: By default, WordPress uses the wp-prefix for database tables, which makes automated attacks easier. Changing it to a custom prefix reduces exposure to SQL injection attempts.
• Restrict Database Access Privileges: Grant database users only the permissions they need. Avoid using root or admin accounts for daily operations to limit the potential damage from a compromised account.
• Use Strong Credentials: Ensure that your database username and password are complex, unique, and regularly updated to prevent unauthorized access.
• Regular Backups: Maintain frequent, automated backups of your database to quickly recover from accidental data loss or attacks.
• Encrypt Sensitive Data: Encrypting user information and critical data adds an additional layer of security, making it difficult for attackers to exploit.

Implementing these practices as part of your WordPress Security Audit helps prevent data breaches, protect user information, and maintain the overall integrity and reliability of your website.

10. Monitor and Review Logs Regularly

Monitoring website activity is an essential final step in a WordPress Security Audit. Logs serve as a vital record of everything happening on your website, including user logins, failed login attempts, file changes, and plugin updates. These logs allow website administrators to detect anomalies and suspicious activities before they escalate into serious security breaches. Regularly reviewing these logs can help identify patterns of attempted hacks, unauthorized access attempts, or unusual file modifications that may indicate malware infections. Implementing security plugins with real-time monitoring, alerts, and detailed reporting makes this process more efficient and proactive. Using wordpress multilingual plugins can also help monitor activity across different language versions of your site.

Some plugins also offer automated actions, such as temporarily blocking IP addresses after repeated failed login attempts or notifying admins of critical file changes. By continuously tracking and analyzing website activity, you create a vigilant security environment that not only detects potential threats early but also strengthens overall website resilience. This step ensures that your website remains secure, reliable, and capable of defending against emerging cyber threats, making it a crucial component of any comprehensive WordPress Security Audit.
