WordPress Security Checklist

A clear, actionable checklist to keep at the root of your WordPress operations.

Maintaining the security of your WordPress site isn’t just about installing a security plugin and hoping for the best—it’s a careful and methodical process. With threats constantly evolving, you need a clear, actionable checklist to ensure your WordPress site stays protected from vulnerabilities, hackers, and exploits.

In this guide, we’ve distilled years of security expertise into a straightforward WordPress security checklist. Follow along and tighten your website’s defenses step-by-step.


Your Complete WordPress Security Checklist

✅ Update WordPress Core Regularly

Regular core updates are fundamental. WordPress frequently releases security patches addressing vulnerabilities, so keeping your installation current drastically reduces your risk.

✅ Audit Your Plugins and Themes

Outdated, abandoned, or poorly coded plugins and themes are prime targets for hackers. Regularly audit your plugins and themes, delete unused ones, and ensure those you keep are consistently updated.

✅ Enforce Strong Passwords and User Permissions

Weak passwords and overly generous user permissions create open doors for attackers. Always use complex, unique passwords, consider two-factor authentication, and review permissions regularly to limit unnecessary admin access.

✅ Perform Regular Backups

No security strategy is foolproof without backups. Regularly backup your website to a secure, off-site location. This ensures quick recovery if something ever goes wrong.

✅ Install SSL Certificates (HTTPS)

SSL certificates encrypt the connection between your visitors and your website, protecting sensitive data and boosting trust. This is essential not just for security, but also for SEO and user experience.

✅ Conduct Regular Penetration Testing

Simulate cyberattacks regularly to discover hidden vulnerabilities before attackers do. Penetration testing proactively identifies weaknesses, allowing you to patch them before exploitation occurs.

✅ Monitor and Clean Up Old Subdomains

Unused or forgotten subdomains can serve as hidden backdoors for hackers. Regularly scan, identify, and disable subdomains that are no longer active or maintained.

✅ Harden Your Hosting Environment

Security begins at the hosting level. Ensure you choose a reliable, secure hosting provider with active security practices. Monitor your server environment closely for suspicious activity.

✅ Set Up a Web Application Firewall (WAF)

A Web Application Firewall filters traffic, blocks suspicious requests, and protects against common WordPress attacks such as SQL injections, brute force attacks, and cross-site scripting (XSS).

✅ Implement Real-Time Security Monitoring

Security monitoring allows you to detect unusual activity immediately. Setting up alerts for login attempts, file changes, and unauthorized access helps catch attacks early.


Other Organizational-Level Security Checklist Items

✅ Look Out for Link Poisoning

Hackers often inject malicious links into reputable sites to manipulate SEO or trick visitors. Regularly scan your website’s pages and links for suspicious or unauthorized content.

✅ Monitor and Clean Up Old Subdomains

Unused or forgotten subdomains can serve as hidden backdoors for hackers. Regularly scan, identify, and disable subdomains that are no longer active or maintained.

🔸 Prevent Subdomain Takeovers

Hackers frequently exploit forgotten or improperly configured subdomains to hijack your brand identity. Routinely check DNS entries, and remove or redirect unused records immediately.

🔸 Regularly Audit Subdomains

Periodically audit your entire DNS infrastructure. Tools like DNS enumeration scanners help identify unused subdomains, making it easy to eliminate unnecessary risk.

✅ Guard Against Phishing Attacks

Phishing remains one of the most common and damaging threats online. Here’s how to stay protected:

🔸 Employee Training & Awareness

Regularly educate your team on identifying phishing attempts, suspicious emails, and malicious links. Awareness significantly reduces the likelihood of successful phishing attacks.

🔸 Verify Sender Information

Always check email addresses and domain authenticity. Consider deploying email security tools that detect spoofing attempts and block malicious senders.

🔸 Use Email Authentication Protocols

Implement SPF, DKIM, and DMARC protocols on your email servers. These protocols greatly reduce the risk of email spoofing and phishing.

✅ Always Use a VPN

A Virtual Private Network (VPN) encrypts your internet connection, making it difficult for attackers to intercept sensitive data. Here’s why it’s crucial:

🔸 Secure Remote Access

Employees working remotely should always connect through a reputable VPN service to protect sensitive information and credentials from interception or man-in-the-middle attacks.

🔸 Prevent Data Leakage

A VPN masks your IP address and encrypts network traffic, significantly reducing the risk of data leaks or surveillance.

✅ General IT Security Best Practices

🔸 Regularly Update Operating Systems and Applications

Keep all software, not just WordPress, regularly updated. Updates frequently contain critical security patches and fixes.

🔸 Implement Multi-Factor Authentication (MFA)

MFA adds extra layers of security beyond passwords, reducing the risk of unauthorized access even if credentials are compromised.

🔸 Maintain Strong Network Security

Regularly audit your network security, ensuring firewalls, routers, and switches have secure configurations and updated firmware.

🔸 Encrypt Sensitive Data at Rest and in Transit

Always encrypt data, especially personal or financial information, both when stored and when transferring between systems.

🔸 Conduct Regular Employee Security Training

Educate your entire team regularly about current cyber threats, secure practices, and proper response procedures to ensure security awareness at all levels.

🔸 Enforce Regular Password Changes and Policies

Use a password manager to enforce regular password updates and ensure adherence to password complexity policies.


Future-Proofing Your WordPress Security

Following this checklist greatly reduces your risk—but security isn’t static.

As threats evolve, so must your defenses. Regularly revisit this checklist, adapt to emerging threats, and stay vigilant.
