Introduction

How to Secure Your WordPress Site from Hackers is one of the most important skills every website owner should learn. Every day, thousands of WordPress websites are targeted by automated bots, malware, brute-force login attempts, and other cyberattacks. A single security vulnerability can result in stolen data, damaged SEO rankings, lost customers, and even complete website downtime.

The good news is that WordPress is highly secure when it’s maintained properly. By following a few proven security practices, you can dramatically reduce the risk of hackers compromising your website. Most attacks succeed because websites are outdated, poorly configured, or missing basic security measures.

In this guide, I’ll share the same security checklist I use when setting up WordPress websites for clients. These practical steps are beginner-friendly, easy to implement, and effective for both personal blogs and business websites.

Why WordPress Websites Get Hacked

Hackers don’t usually target WordPress itself—they look for weak websites with outdated software or poor security practices.

Common reasons websites get hacked include:

• Outdated WordPress versions
• Vulnerable plugins
• Outdated themes
• Weak passwords
• Poor hosting security
• Malware infections
• Brute-force attacks
• Incorrect file permissions

Most of these issues can be prevented with regular maintenance and a few simple security settings.

---

Keep WordPress Updated

One of the easiest ways to improve website security is to keep WordPress updated.

Every update may include:

• Security patches
• Bug fixes
• Performance improvements
• Compatibility updates

Before updating WordPress:

• Create a full website backup.
• Update plugins first.
• Update your active theme.
• Test your website after the update.

Use Strong Login Credentials

Weak usernames and passwords remain one of the biggest causes of hacked WordPress websites.

Avoid using:

• admin
• administrator
• password123
• 12345678

Instead:

• Use a unique username.
• Create a password with at least 16 characters.
• Include uppercase and lowercase letters.
• Add numbers and symbols.
• Store passwords in a password manager.

Strong credentials make brute-force attacks much less effective.

---

Enable Two-Factor Authentication

Two-factor authentication (2FA) adds an extra verification step after entering your password.

Even if someone steals your password, they still need access to your authentication code.

Popular 2FA apps include:

• Google Authenticator
• Microsoft Authenticator
• Authy

Most modern WordPress security plugins include built-in support for two-factor authentication.

Install a WordPress Security Plugin

A reliable security plugin protects your website from many common attacks without requiring advanced technical knowledge.

Popular security plugins include:

• Wordfence Security
• Solid Security (formerly iThemes Security)
• Sucuri Security
• All In One WP Security & Firewall

These plugins provide features such as:

• Malware scanning
• Firewall protection
• Login protection
• File integrity monitoring
• Security notifications

Install only one comprehensive security plugin to avoid conflicts.

Configure Basic Security Settings

After installing your security plugin, enable these recommended features:

• Web Application Firewall (WAF)
• Malware scanning
• Login protection
• File change detection
• Email security alerts

Run a full security scan after completing the initial configuration.

---

Use SSL Encryption

SSL encrypts all data transferred between your visitors and your website.

Without SSL:

• Login credentials can be intercepted.
• Sensitive information is exposed.
• Browsers may label your website as “Not Secure.”

You can identify SSL-enabled websites by the padlock icon and the https:// prefix.

Most hosting providers, including Hostinger, offer free SSL certificates.

Change the Default Login URL

By default, every WordPress website uses:

/wp-login.php

or

/wp-admin

Hackers know these URLs and often target them with automated login attempts.

Changing the login URL makes brute-force attacks more difficult because attackers can no longer easily locate your login page.

Several security plugins allow you to change the login URL without editing core files.

---

Limit Login Attempts

Unlimited login attempts make brute-force attacks much easier.

Limiting failed login attempts helps block bots that repeatedly try different username and password combinations.

Recommended settings:

• Maximum failed attempts: 5
• Lockout duration: 30 minutes
• Permanent block after repeated lockouts

Most security plugins include this feature.

---

Secure the wp-config.php File

The wp-config.php file contains your website’s most sensitive information, including database credentials and security keys.

Protect this file by:

• Setting proper file permissions.
• Keeping it outside the public directory if your hosting supports it.
• Never sharing its contents publicly.
• Regularly reviewing it for unauthorized changes.

A secure wp-config.php file significantly reduces the risk of attackers accessing your website configuration.

How to Edit wp-config.php Safely

---

Disable File Editing from the WordPress Dashboard

By default, WordPress allows administrators to edit theme and plugin files directly from the dashboard.

If an attacker gains admin access, this feature can be abused to inject malicious code.

To disable file editing, add the following line to your wp-config.php file:

define('DISALLOW_FILE_EDIT', true);

This small change improves security by preventing code edits through the WordPress admin panel.

---

Secure File Permissions

Incorrect file permissions can make your WordPress website vulnerable to unauthorized access. Setting the correct permissions ensures that only the necessary users and processes can read or modify files.

Use these recommended permissions:

File/Folder	Permission
Folders	755
Files	644
wp-config.php	600 or 640

Avoid using 777 permissions, as they give everyone full access and create a major security risk.

---

Enable a Website Firewall (WAF)

A Web Application Firewall (WAF) acts as the first line of defense between your website and attackers. It filters malicious traffic before it reaches your WordPress installation.

A firewall can protect your site from:

• Brute-force login attempts
• SQL injection attacks
• Cross-site scripting (XSS)
• Malware requests
• Suspicious bots

Many WordPress security plugins include a built-in firewall, while cloud-based services provide additional protection.

Enable Firewall Rules

After enabling your firewall, configure these settings:

• Block known malicious IP addresses
• Enable bot protection
• Protect the login page
• Enable country blocking if required
• Monitor firewall logs regularly

A properly configured firewall blocks many attacks before they reach your website.

---

Scan Your Website for Malware Regularly

Even secure websites should be scanned regularly. Malware can be injected through vulnerable plugins, outdated themes, or compromised administrator accounts.

Schedule automatic malware scans weekly or daily if your website handles sensitive information.

Look for:

• Suspicious PHP files
• Modified core files
• Unknown administrator accounts
• Hidden redirects
• Spam links

Remove any detected malware immediately and change all administrator passwords afterward.

---

Disable XML-RPC if You Don’t Need It

XML-RPC is a WordPress feature that allows remote communication with your website. While useful for certain applications, it is also a common target for brute-force and DDoS attacks.

If you don’t use mobile publishing apps or remote publishing tools, consider disabling XML-RPC to reduce potential attack vectors.

Several security plugins provide a one-click option to disable it safely.

---

Protect Your Database

Your database stores all of your website’s content and settings, making it one of the most valuable targets for attackers.

Improve database security by:

• Using strong database passwords
• Limiting database user privileges
• Changing the default database table prefix during installation
• Removing unused database tables
• Optimizing the database regularly

These practices reduce the chances of unauthorized database access.

Enable Automatic Backups

Backups are your safety net. If your website is hacked or infected with malware, a recent backup allows you to restore it quickly.

A good backup strategy includes:

• Daily automatic backups
• Weekly full backups
• Off-site cloud storage
• Regular backup testing

Reliable backup plugins make this process simple and automatic.

Choose Secure WordPress Hosting

Your hosting provider plays a significant role in your website’s security.

Look for hosting that includes:

• Free SSL certificates
• Malware scanning
• Daily backups
• Server-level firewall
• DDoS protection
• Automatic updates
• 24/7 support

Quality hosting reduces the risk of many common security issues before they reach your website.

---

Monitor User Accounts

Review administrator accounts regularly and remove any users who no longer require access.

Follow these best practices:

• Limit the number of administrators.
• Assign the lowest required user role.
• Delete inactive accounts.
• Enable two-factor authentication for administrators.

This reduces the chances of unauthorized access through compromised accounts.

---

Common WordPress Security Mistakes

Many website owners unintentionally create security risks.

Avoid these common mistakes:

• Ignoring WordPress updates
• Installing plugins from untrusted sources
• Using weak passwords
• Keeping unused plugins activated
• Not creating regular backups
• Disabling security scans
• Giving administrator access to every user
• Ignoring malware warnings

Avoiding these mistakes can significantly improve your website’s security.
