How to Secure Your WordPress Website in 2024

1. Set Strong Passwords and Login Rules

Weak passwords are a common vulnerability in WordPress sites, making them an easy target for hackers. Setting up strong password policies and login rules is a must to keep your website secure.

Strong Password Guidelines

Here’s what you should enforce for passwords:

• Use at least 20 characters.
• Include a mix of uppercase and lowercase letters.
• Add numbers and special characters.
• Avoid predictable choices like common words, names, or dates.
• Require users to update passwords every 120 days.

“Your WordPress security is only as good as your WordPress password security. If you have a simple password, you have a simple site to hack.” – SolidWP ^[5]

Login Protection Tips

Boost login security by applying these methods:

User Role Management

Restricting access and managing user roles carefully is another layer of protection. Follow these practices:

• Grant Administrator access only to essential team members.
• Enable two-factor authentication for all admin accounts.
• Remove inactive user accounts right away.
• Reassign content when removing users with Author roles.
• Conduct regular audits of user roles.

Using a password manager can simplify creating and storing complex passwords. WordPress itself generates 24-character passwords ^[4], and you can enforce this across all accounts with plugins like iThemes Security or Melapress Login Security ^[5][6].

These steps build a strong foundation for login security. To take it even further, consider adding two-factor authentication.

2. Add Two-Factor Authentication

Strengthening your login setup is crucial, and adding two-factor authentication (2FA) takes your security to the next level. With cyberattacks happening every 39 seconds and around 13,000 WordPress sites targeted daily in 2023 ^[8], 2FA is a smart way to protect your site.

How 2FA Works

2FA adds an extra layer of security by requiring two steps to verify your identity:

• Your password (the first layer)
• A second method that only you can access

This second method could be an authenticator app, a security key, push notifications, email links, or SMS codes (though SMS is generally not recommended ^[11]). Below are some plugins that make adding 2FA simple.

Recommended 2FA Solutions

• WP 2FA (4.6/5 stars) ^[10]

• miniOrange’s Google Authenticator ($15/year) ^[7]

Implementation Tips

To make 2FA effective, keep these tips in mind:

• Make it mandatory for all users.
• Roll it out in phases to ensure a smooth transition.
• Consider adaptive multi-factor authentication (MFA) for added flexibility.
• Document recovery steps for users.
• Provide secure storage for backup codes.

Overcoming Common Challenges

Despite its benefits, 68% of users skip 2FA ^[12]. To tackle this issue:

• Offer clear, step-by-step setup instructions.
• Ensure your system is fully compatible with 2FA.
• Plan for integrating older systems.
• Clearly explain how 2FA improves security to encourage adoption.

3. Update WordPress Core, Themes, and Plugins

Keeping your WordPress installation up to date is one of the most effective ways to protect your site. Outdated versions of WordPress, themes, or plugins are often exploited by hackers. In fact, over 50% of hacked websites were compromised because of outdated plugins and themes ^[15].

Why Updates Matter

WordPress frequently releases updates to fix security issues and vulnerabilities. In 2023, 75% of WordPress sites were running version 6, while the remaining 25% using older versions were at a much higher risk of being hacked ^[13].

How to Update Safely

Before making any updates, always create a backup of your site using a reliable plugin ^[16][18]. If possible, test updates in a staging environment to avoid unexpected downtime ^[18].

Tips for Updating

• Check Compatibility: Review changelogs and documentation to ensure updates are compatible with your WordPress version, themes, and plugins.
• Update One at a Time: Apply updates individually ^[17].
• Test After Updates: Check key features like forms, contact pages, e-commerce functionality, admin access, and overall site speed after each update.

Addressing potential issues during updates is just as important as applying them.

Common Issues and Fixes

Here’s how to resolve some frequent problems when updating:

Always download updates from trusted sources like the official WordPress repository to ensure security ^[14].

Automating Updates

Consider enabling automatic updates for minor security patches while manually reviewing and approving major updates. This approach ensures you stay protected without risking unexpected changes to your site’s functionality.

4. Choose the Right Security Plugin

Picking the right security plugin is key to protecting your site from cyberattacks ^[19]. With WordPress powering more than 60% of websites, it’s a popular target for hackers ^[19]. Below, we’ve compared some of the best plugins to help you find the one that suits your needs.

While strong passwords and regular updates are your first line of defense, a security plugin adds an extra layer of protection.

Top Security Plugins Comparison

Here’s a quick breakdown of top WordPress security plugins:

• Impact on Site Performance: Make sure the plugin doesn’t slow down your site.

These features ensure your site stays secure without compromising usability.

Performance Matters

For high-traffic websites, how a plugin uses resources is a big deal. Wordfence, for example, has over 4,000 five-star reviews ^[22], but some hosting providers avoid it due to its resource demands ^[19]. Plugins like MalCare or Sucuri are better choices for balancing performance and protection ^[23].

Choosing the Best Plugin for You

Ultimately, the right plugin depends on your site’s size, budget, and specific needs. For instance, e-commerce sites often require more robust security features than a basic business site. Take into account your technical expertise too – some plugins are more user-friendly than others.

5. Set Up SSL Security

SSL certificates play a key role in protecting data and building user trust. Alongside measures like strong passwords and two-factor authentication (2FA), SSL ensures secure data transmission. As of November 2024, HTTPS pages make up over 93% of browsing time on Chrome ^[27].

Why SSL Matters

SSL encrypts data, safeguarding credentials and securing transactions. It also displays a trusted padlock icon in the browser and can improve search rankings. Google has prioritized HTTPS as a ranking signal since 2014 ^[26].

Types of SSL Certificates

SSL works alongside other security measures to protect data transfers and strengthen your site’s overall defenses.

How to Implement SSL

Follow these steps to secure your WordPress site:

1. Install the Certificate
   Obtain an SSL certificate through your hosting provider or free services like Let’s Encrypt ^[25].
2. Update WordPress Settings
   Adjust the WordPress Address and Site Address in the admin panel to use HTTPS ^[25].
3. Redirect Traffic
   Set up automatic redirection from HTTP to HTTPS to ensure all traffic is secure ^[25].

Common Mistakes to Avoid

“Users find it easier to trust a secure site… they do know the little padlock icon means a site cares about their privacy.” – Developer.WordPress.org ^[24]

To maintain SSL protection:

• Keep track of certificate expiration dates.
• Use tools like Qualys SSL Labs to verify proper installation.
• Update internal links to use HTTPS.
• Configure Google Search Console for the HTTPS version of your site ^[25].

6. Create Regular Website Backups

Backups are your last line of defense against data loss and downtime. With over 43% of businesses worldwide using WordPress as their website platform ^[28], having a solid backup plan is critical to keeping your site running smoothly. This step works hand-in-hand with other security measures to ensure you can bounce back quickly after any issues.

Backup Types and Scheduling

Not all backups are the same. Here’s a breakdown of common types and when to use them:

The 3-2-1 Backup Rule

Follow the 3-2-1 rule: keep three copies of your data, store them on two different types of storage, and have one copy off-site ^[30]. This approach minimizes risks from hardware failures or cyberattacks.

Automated Backup Tools

Consider using automated solutions to simplify the process:

• BlogVault ($149/year): Great for larger sites, offering incremental backups and unlimited offsite storage ^[31].
• UpdraftPlus ($70/year): A good option for smaller sites with 1GB storage and multiple cloud integrations ^[31].
• Duplicator ($69/year): Ideal for advanced users who need migration features ^[31].

Tips for Managing Backups

• Schedule backups during low-traffic hours to avoid slowing down your site ^[28].
• Test your backups regularly by restoring them in a staging environment to ensure they work ^[29].
• Monitor backup success with uptime monitoring tools to confirm schedules run as expected ^[28].
• Delete local backup files after transferring them to remote storage for added security ^[28].

Where to Store Your Backups

Modern backup solutions use encryption to secure data during storage and transfer ^[33]. However, backups provided by web hosts are often stored on the same server as your site, which can be risky ^[34]. To keep your data extra safe, configure your backups to automatically save copies to secure cloud services like Google Drive, Dropbox, or Amazon S3. That way, even if your main server goes down, your backups are protected ^[32].

7. Install a Web Application Firewall

A Web Application Firewall (WAF) serves as a shield between your visitors’ browsers and your web server. It filters traffic at the application layer, blocking advanced attacks like SQL injection and cross-site scripting ^[35]. With WordPress powering 40% of the web, it’s often a target for cyber threats, making a WAF an essential security tool ^[36].

Comparing Top WAF Options

Here’s a quick breakdown of some popular WAF solutions for WordPress:

Each of these options has distinct features and pricing, so choose the one that best fits your website’s needs.

Best Practices for Setting Up a WAF

• Opt for a DNS-level firewall for better efficiency ^[37].
• Regularly update threat signatures to stay ahead of new vulnerabilities.
• Customize firewall rules to align with your website’s requirements.
• Continuously monitor performance and fine-tune settings as necessary.

Zero-Day Threat Protection

Modern WAFs can detect and block emerging threats before patches are released. This provides critical protection against zero-day vulnerabilities, especially for business-oriented websites.

Additional Security Features

Many WAFs come with enhanced tools, such as:

• Real-time Traffic Analysis to identify suspicious activity
• Brute Force Prevention to stop unauthorized login attempts
• Bot Protection to reduce spam and automated attacks
• Performance Optimization to ensure your site runs smoothly

Implementing a WAF not only enhances your site’s security but also helps maintain its reliability and performance.

8. Track Site Activity and Run Security Checks

Monitoring your website helps catch threats before they become serious problems. In 2022, 96.2% of attacks targeted WordPress ^[2]. For business websites, keeping track of activity and running regular scans is a must. Below, we’ll look at tools and strategies to stay ahead.

Tools for Monitoring Activity

Modern WordPress monitoring tools provide detailed insights into user behavior and potential threats. Here’s a comparison of a few popular options:

Key Metrics to Watch

Pay attention to these critical security metrics to keep your site safe:

• Failed login attempts: A spike could indicate a brute-force attack.
• File and database changes: Unauthorized modifications can signal a breach.
• Plugin and theme updates: These are common entry points for attackers.
• Changes to user permissions: Unexpected alterations could be a red flag.
• Unusual traffic patterns: Sudden spikes or drops may indicate malicious activity.
• Server connectivity issues: Frequent outages might point to deeper problems.

These metrics help you decide how often to run audits and what to focus on.

How Often Should You Scan?

For sites handling sensitive data, monthly security audits are recommended. For others, quarterly checks should suffice ^[39]. Always perform an immediate review after major updates or when unusual activity is detected.

“Swift action on those notifications is equally essential.” – Mart Virkus, Head of Marketing, Patchstack ^[40]

Addressing Vulnerabilities

Did you know that 90% of WordPress security issues come from plugins ^[39]? When reviewing your site, focus on these common threats:

• Cross-site scripting (XSS): These account for 50% of plugin vulnerabilities.
• Cross-site request forgery (CSRF): Found in 15% of cases.
• SQL injection attempts
• Malware infections
• Unauthorized file permission changes

Real-World Example

Proactive monitoring delivers results. For instance, WPBeginner used Sucuri’s tools to block over 450,000 attacks in just three months ^[38]. With ransomware payouts averaging $1,542,333 in 2023 ^[41], staying ahead of threats isn’t optional – it’s necessary.

Tips for Effective Implementation

Here are some best practices to ensure your monitoring is effective:

• Set up real-time alerts for critical events.
• Log and review all admin actions regularly.
• Restrict access to activity logs.
• Enable visual change monitoring to catch unauthorized edits.

9. Lock Down WordPress Database

After securing WordPress logins and files, it’s equally important to focus on protecting your database. The database holds critical business data, making it a priority in your site’s overall security strategy.

Strengthen Database Security

Start by changing the default WordPress table prefix, which is often set to wp_. Sticking with the default makes your site an easier target for automated attacks ^[44]. Here’s a quick comparison of key security measures for your database:

Key Steps to Protect Your Database

Input Validation and Sanitization
Use wpdb->prepare for sanitizing inputs ^[43]. This step is crucial in defending against SQL injection attacks that could compromise your database.

Access Control
SQL injection can expose sensitive details like usernames, passwords, and even financial information. Limit database privileges to reduce the risk of unauthorized access ^[43].

Error Message Management
Avoid displaying detailed error messages. Instead, create generic error pages to prevent attackers from learning about your database structure ^[42].

Monitoring and Prevention Tools

Regularly monitor SQL statements between your database and connected applications to catch vulnerabilities early ^[42]. Some popular tools include:

• Sucuri: Comprehensive database protection starting at $229/year ^[21].
• MalCare: Offers deep scanning for $149/year ^[21].
• Wordfence: Includes free database monitoring features ^[21].

Best Practices for Database Security

• Firewall Protection: Use a web application firewall to monitor and control database access ^[42].
• Encryption: Encrypt sensitive data to keep it secure ^[42].
• Audit Logs: Maintain detailed logs of database activities to detect and investigate potential breaches ^[43].

Real-Time Security Measures

Modern WordPress security plugins can provide real-time database protection. Features like malware scanning, automated backups, SQL injection prevention, and activity monitoring are essential for keeping your database safe. These tools add an extra layer of defense to your overall security plan.

10. Set Correct File Permissions

Beyond securing your login credentials and database, setting the right file permissions is another key step to safeguard your WordPress site.

File permissions determine who can read, write, or execute your WordPress files and directories. These permissions are represented by numeric values: read (4), write (2), and execute (1).

Understanding WordPress File Permissions

Key Security Settings

To protect your site, set these permissions:

• Directories (e.g., public_html, wp-admin, wp-includes, wp-content): 755
• Regular files (e.g., index.php, .htaccess, theme and plugin files): 644
• wp-config.php: 640

These settings prevent unauthorized access while maintaining functionality ^[45].

How to Update File Permissions

There are two main ways to adjust file permissions:

• Using an FTP client: Open your WordPress root directory, right-click the file or folder, choose ‘File Permissions,’ and input the correct numeric value.
• Via SSH for bulk changes: Run the following commands:

  find . -type f -exec chmod 644 {} +  
  find . -type d -exec chmod 755 {} +
  

“Improper file permissions enable attackers to gain unauthorized access.” – getastra.com ^[46]

Tips for Managing File Permissions

• Always create a backup before making any changes.
• Stick to the principle of least privilege – only allow access that’s absolutely necessary.
• Check your site’s functionality after updates to ensure nothing breaks.
• Regularly review file access logs for suspicious activity.
• Use security plugins to scan and audit file permissions automatically.

Conclusion

Protecting your WordPress website is more important than ever, with cybercrime damages expected to reach $10.5 trillion annually by 2025 ^[48]. Considering WordPress powers nearly half of all websites globally and faces 4.7 million hack attempts each year ^[1], securing your site isn’t just smart – it’s essential for staying in business.

Every day, Google blacklists around 10,000 websites due to malware or phishing ^[3]. The main culprits? Outdated software and weak passwords ^[1]. These risks can be drastically reduced by following proper security practices.

Taking security seriously also has practical benefits:
