WordPress powers over 40% of the web, which makes it the biggest target for hackers by a wide margin. The good news is that WordPress itself is well-maintained and secure when properly configured. Most security breaches happen because of outdated software, weak passwords, or preventable misconfigurations.
Here are ten practical steps you can take to keep your WordPress site safe.
1. Keep WordPress, Plugins, and Themes Updated
This is the single most important thing you can do. The majority of WordPress hacks exploit known vulnerabilities in outdated plugins or themes. When developers release an update that patches a security flaw, that flaw becomes public knowledge — and bots start scanning the internet for sites that haven't updated yet.
Enable automatic updates for minor WordPress releases (which include security patches). For plugins and themes, check for updates at least once a week. Remove any plugins or themes you aren't actively using — even deactivated ones can be exploited if they have vulnerabilities.
2. Use Strong Passwords and Two-Factor Authentication
Brute-force attacks — where bots try thousands of password combinations — are one of the most common attacks against WordPress. A password like admin123 will be cracked in seconds.
Use a unique, randomly generated password for your WordPress admin account (a password manager makes this painless). Then add two-factor authentication (2FA) as a second layer. Even if someone guesses your password, they can't get in without the second factor. Plugins like WP 2FA or Wordfence Login Security add 2FA in minutes.
3. Choose Secure Hosting
Your hosting environment is the foundation of your site's security. A good host provides server-level firewalls, malware scanning, automatic backups, and isolation between accounts so one compromised site can't affect others on the same server.
SpectraHost's WordPress hosting includes these protections by default, plus optimized server configurations for WordPress performance and security. The hosting layer is the one part of your security stack you can't fully control yourself — choose a provider that takes it seriously.
4. Install a Security Plugin
A WordPress security plugin adds features that WordPress doesn't include out of the box: file integrity monitoring, login attempt logging, malware scanning, and firewall rules. Popular options include Wordfence, Sucuri Security, and iThemes Security.
You don't need all of them — one solid security plugin is enough. Configure it once and let it run in the background, alerting you to anything suspicious.
5. Limit Login Attempts
By default, WordPress allows unlimited login attempts. That's an open invitation for brute-force attacks. Limiting login attempts to three or five before a temporary lockout stops most automated attacks cold.
Most security plugins include this feature, or you can use a standalone plugin like Limit Login Attempts Reloaded. You can also change the default login URL from /wp-admin to something custom, though this is security through obscurity and shouldn't be your only defense.
6. Disable XML-RPC If You Don't Need It
XML-RPC is a WordPress feature that allows external applications to communicate with your site. It was essential years ago for things like the WordPress mobile app and remote publishing tools. Today, the REST API handles most of those use cases better and more securely.
XML-RPC is a common attack vector for brute-force login attempts and DDoS amplification. If you don't use a tool that specifically requires it, disable it. Many security plugins offer a one-click toggle for this.
7. Use SSL Everywhere
An SSL certificate encrypts the connection between your visitors' browsers and your server. This protects login credentials, form submissions, payment data, and personal information from being intercepted.
Beyond security, SSL is now a ranking factor for search engines, and browsers display "Not Secure" warnings for sites without it. Make sure your entire site loads over HTTPS — not just the login page. WordPress has a setting for this under Settings → General, and plugins like Really Simple SSL can handle the migration if you're switching from HTTP.
8. Set Up Regular Backups
Backups won't prevent an attack, but they're your safety net when something goes wrong. If your site gets compromised, a clean backup means you can restore it in minutes instead of rebuilding from scratch.
Follow the 3-2-1 rule: three copies of your data, on two different media types, with one stored offsite. Use a backup plugin like UpdraftPlus or BlogVault to schedule automatic daily backups, and store copies in cloud storage (Google Drive, Dropbox, or Amazon S3) — not just on your hosting server.
SpectraHost also includes server-level backups, giving you an additional layer of protection beyond your WordPress backup plugin.
9. Set Correct File Permissions
File permissions control who can read, write, and execute files on your server. Incorrect permissions can allow attackers to modify your files or inject malicious code.
The standard WordPress permissions are:
- Directories:
755(owner can read/write/execute, others can read/execute) - Files:
644(owner can read/write, others can read only) wp-config.php:600or640(restricted access — this file contains your database credentials)
Never set permissions to 777 (full access for everyone). If a plugin asks you to do this, find a different plugin.
10. Monitor Your Site
Security isn't a one-time setup — it requires ongoing awareness. Monitor your site for unexpected changes: new admin users you didn't create, modified files, unfamiliar plugins, or sudden traffic spikes that could indicate an attack.
Your security plugin should handle most monitoring automatically. Pair it with uptime monitoring to get alerted if your site goes down unexpectedly. Check the SpectraHost security overview for details on what's included with your hosting plan.
Start With a Secure Foundation
Most WordPress security issues are preventable. Keep your software updated, use strong credentials, choose quality hosting, and set up backups — those four actions alone eliminate the vast majority of threats.
