WordPress Security Basics: Protect Your Website from Threats

WordPress is one of the most popular content management systems, powering over 40% of websites globally. However, its popularity also makes it a prime target for cyberattacks. Understanding and implementing basic security measures is essential to safeguard your website from vulnerabilities, malware, and unauthorized access.

This guide outlines fundamental steps to enhance your WordPress security and ensure a safer online presence.

Why WordPress Security Is Crucial

1. Prevent Data Breaches

• Protect sensitive user data such as emails, passwords, and payment information.

2. Avoid Downtime

• Hacked websites may face outages, resulting in lost revenue and trust.

3. Maintain Reputation

• A secure site enhances credibility with users and search engines.

Step 1: Secure Login Practices

1. Use Strong Passwords

• Avoid common passwords like “123456” or “password.”
• Use a password manager to create and store complex passwords.

2. Enable Two-Factor Authentication (2FA)

• Add an extra layer of security by requiring a verification code along with your password.
• Recommended plugins: Google Authenticator or Wordfence Login Security.

3. Change Default Admin Username

• Avoid using “admin” as your username, which is often targeted in brute-force attacks.

Step 2: Keep WordPress Updated

1. Update Core, Plugins, and Themes

• Regularly update WordPress to the latest version to patch vulnerabilities.
• Enable automatic updates for minor releases.

2. Remove Inactive Plugins and Themes

• Deactivate and delete unused plugins and themes to minimize attack vectors.

Step 3: Install a Security Plugin

Recommended Security Plugins

Step 4: Protect Your Files

1. Change File Permissions

• Restrict file permissions to prevent unauthorized access.
• Recommended settings:

  • Directories: 755

2. Disable File Editing

• Prevent users from editing theme or plugin files via the dashboard.
• Add this code to your wp-config.php file:

define('DISALLOW_FILE_EDIT', true);

3. Secure wp-config.php

• Move wp-config.php to a higher directory for added protection.
• Restrict access using .htaccess:

<files wp-config.php> 
order allow,deny 
deny from all 
</files>

Step 5: Set Up a Web Application Firewall (WAF)
