WordPress Security Basics: Protecting Your Site from Hackers

WordPress is the most popular website platform in the world, which also makes it the biggest target for hackers. Most WordPress hacks are not sophisticated attacks by skilled hackers. They are automated bots scanning the internet for sites with known vulnerabilities, weak passwords, or outdated software.

The good news is that securing your WordPress site does not require deep technical knowledge. A handful of fundamental practices will protect you from the vast majority of attacks.

Keep Everything Updated

The single most important security measure is keeping WordPress core, themes, and plugins updated. Most WordPress hacks exploit known vulnerabilities in outdated software. When developers discover a security flaw, they release an update to fix it. If you do not install that update, your site remains vulnerable.

Enable automatic updates for WordPress core and plugins. Check for updates weekly and apply them promptly. If a plugin or theme has been abandoned (no updates for over a year), replace it with an actively maintained alternative.

Website Security Checklist

Use Strong Passwords

Weak passwords are the second most common attack vector. Do not use common passwords, dictionary words, or easily guessable combinations. Every admin account should use a unique password of at least 16 characters with a mix of letters, numbers, and symbols.

Use a password manager to generate and store strong passwords. Never reuse passwords across sites. If one site is breached and you used the same password on your WordPress site, attackers will try it there too.

WordPress allows unlimited login attempts by default, which makes brute force attacks easy. A brute force attack is when a bot tries thousands of username and password combinations until it gets in.

Install a plugin that limits login attempts. After a set number of failed attempts (typically three to five), the plugin blocks that IP address for a period. This makes brute force attacks impractical.

Bots target the default WordPress login page at /wp-admin and /wp-login.php. Changing your login URL to something custom eliminates these automated attacks because bots cannot find your login page.

Several plugins can change your login URL with a few clicks. Choose a URL that you will remember but that bots will not guess.

Install a Security Plugin

A comprehensive security plugin adds multiple layers of protection. Look for one that includes:

A web application firewall to block malicious traffic
Malware scanning to detect compromised files
Login security features like two-factor authentication
File integrity monitoring to alert you when core files change
IP blocking to ban known malicious addresses

Popular options include Wordfence and Sucuri. Either one provides solid protection for most sites.

Set Up Regular Backups

Backups are your insurance policy. If your site is hacked and you cannot clean it, you need to be able to restore a clean version. Without backups, a hack could mean rebuilding your entire site from scratch.

Set up automated daily backups that store copies off-site (not just on your hosting server). Test your backup restoration process at least once to make sure it actually works.

Additional Security Measures

Use two-factor authentication for all admin accounts
Remove unused themes and plugins (they can still be exploited even when deactivated)
Disable file editing through the WordPress dashboard
Use a hosting provider that includes server-level security measures
Keep your computer and devices secure since compromised devices can compromise your website
