Why Security Audits are Important

Security audits are the backbone of robust WordPress security. Regular security audits can:

• Prevent data breaches
• Protect sensitive user information
• Maintain your site’s reputation and trustworthiness
• Ensure compliance with data protection regulations

Cyberattacks can lead to significant financial and operational damage, making proactive security measures indispensable for WordPress security.

Preliminary Steps: Backups and Updates

Importance of Backing Up Your Site

Before diving into the security audit, it’s critical to back up your site. In the event something goes wrong during the audit, a backup ensures that you can restore your site to its previous state without data loss.

How to Create a Full Backup

Use reliable plugins like WPMigrate or UpdraftPlus to create a complete backup of your WordPress website, including your database, themes, plugins, and media files.

Updating WordPress Core, Themes, and Plugins

Outdated software is a common entry point for attackers. Ensuring your WordPress core, themes, and plugins are up to date is fundamental for WordPress security. Updates often include security patches that protect against known vulnerabilities.

Step-by-Step Security Audit Process

A. Checking for Weak Passwords and ensuring 2FA is set

Importance of Strong Passwords

Weak passwords are one of the most common vulnerabilities. Ensuring all user accounts have strong, unique passwords is the first line of defence for WordPress security.

Enforce strong password policies when creating accounts and ensure you are implementing Two-Factor Authentication (2FA). The next step highlights the use of WordFence. This plugin has inbuilt 2FA abilities, so use that to keep the number of plugins down.

B. Scanning for Malware

Understanding Malware Threats

Malware can compromise your site’s functionality and steal sensitive information. Regular scans are essential for detecting and removing malicious code to enhance WordPress security.

Recommended Malware Scanning Plugins

Bronte recommends using robust security plugins like Wordfence but there are also other plugins like Sucuri Security for comprehensive malware scanning.

• Wordfence: Offers real-time threat defence and a malware scanner that checks core files, themes, and plugins for better WordPress security.
• Sucuri Security: Provides malware scanning, blacklist monitoring, and advanced security hardening.

How to Run a Malware Scan

Install and configure your chosen plugin, then run a full scan. Follow the plugin’s recommendations to address any detected issues.

C. Reviewing Plugin and Theme Security

Assessing the Security of Installed Plugins and Themes

Every plugin and theme is a potential vulnerability. Regularly review all installed plugins and themes to ensure they’re reputable and up to date.

Identifying and Removing Vulnerable or Unused Plugins

Remove any plugins or themes that are not actively maintained or that you no longer use. This will reduce your site’s attack surface and enhance WordPress security.

D. Verifying File Permissions (Only for some hosting providers)

Importance of Correct File Permissions

Incorrect file permissions can expose sensitive files, making them accessible to attackers. Proper file permissions are fundamental for WordPress security.

How to Check File Permissions

Use an FTP client or your hosting provider’s file manager to review file permissions. The recommended settings are:

• wp-config.php should be 440 or 400
• All directories should be 755
• All files should be 644

At Bronte, we monitor this for you, so you don’t have to worry about your website security when you host with us!

E. Analyzing Server Security

Server Configuration Best Practices

Ensuring your server environment is secure is crucial for overall WordPress security. This includes regular software updates and patches.

How to Secure Your Server Environment

• Disable XML-RPC if it’s not needed.
• Implement a Web Application Firewall (WAF) to filter out malicious traffic.
• Configure HTTP security headers to add additional layers of security.

F. Removing Deactivated Plugins and Themes

Why It’s Important

Deactivated plugins and themes can still be exploited by attackers. Removing them reduces the risk of vulnerabilities and enhances WordPress security.

How to Remove Deactivated Plugins and Themes

• Navigate to the Plugins section in your WordPress dashboard.
• Deactivate and delete any unused plugins.
• Navigate to the Appearance > Themes section.
• Delete any themes that are not in use, keeping only the active theme and a default WordPress theme as a backup.

G. Managing User Roles and Permissions

Evaluate the Necessity of Admin Accounts

Not every user needs admin-level access. Excessive admin accounts increase the risk of security breaches.

Our Recommendation for WordPress Security

Create an admin account solely for maintenance purposes. Assign Editor roles to yourself and other users who require access. This limits the capabilities of compromised accounts and enhances WordPress security.

How to Change User Roles

• Navigate to the Users section in your WordPress dashboard.
• Select the user accounts and change their roles to Editor or other appropriate levels.

H. Implementing a Website Firewall

Why Use a Web Application Firewall (WAF)

A WAF protects your site by filtering out malicious traffic before it reaches your server, enhancing overall WordPress security.

Recommended WAF Solutions

• Cloudflare: Provides comprehensive WAF services, including DDoS protection.
• Sucuri: Offers a robust WAF with global CDN for enhanced site speed and security.

I. Disabling XML-RPC

The Risks of XML-RPC

XML-RPC can be exploited for DDoS attacks and brute force login attempts, posing risks to WordPress security.

How to Disable XML-RPC

• Use a plugin like “Disable XML-RPC” to turn off this feature.
• Alternatively, add the following code to your .htaccess file:
• # Block WordPress xmlrpc.php requests <Files xmlrpc.php> order deny,allow deny from all </Files>

J. Enforcing Secure Login Procedures

Adding Captcha to Login Pages

Implementing CAPTCHA on login pages can prevent automated login attempts and enhance WordPress website security.

Recommended Plugins for CAPTCHA

• WordFence: This plugin already gives you the ability to add reCaptcha to your login forms so use this to avoid other plugins being installed to your site.

Tools for Conducting a Security Audit

Bronte recommends the following tool to assist you in conducting a comprehensive security audit:

• Wordfence: Provides malware scanning, firewall protection, and real-time monitoring for comprehensive WordPress security.

Post-Audit Actions and Follow-Up

Documenting Findings and Creating an Action Plan

Document all vulnerabilities found during your security audit and prioritize them based on risk. Create an action plan to address these issues systematically.

Implementing Security Improvements

Apply the necessary changes to improve your site’s WordPress security. This could involve updating software, changing passwords, or configuring security plugins.

Setting Up Regular Security Audits

Schedule regular security audits—quarterly or even monthly—to ensure ongoing protection and maintain robust WordPress security.

Educating Your Team on Security Best Practices

Security is a team effort. Ensure that everyone involved with your site is educated on security best practices and understands the importance of maintaining a secure environment.

Conclusion: Maintaining Security Over Time

Security is an ongoing process. Continuously monitor your site for threats, stay updated on the latest security risks, and regularly review your security practices. Utilize resources like security blogs, forums, and newsletters to stay informed.
